This is the full series for converting OMAP1 to multiplatform, rebased from my 2019 attempt to do the same thing. The soc tree contains simpler patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which means we are getting closer to completing this for all ARMv5 platforms (I have patches for PXA, which is the last one remaining).
Janusz already tested the branch separately and did the missing work for the common-clk conversion after my previous approach was broken.
The fbdev, mmc and ASoC portion of Janusz' work already went into the corresponding maintainer tree, but I include them here for reference. Unless there are any objections, I would add the entire series to the for-next branch of the soc tree, but only send the first 36 patches early in the merge window. After everything else has made it in, I would rebase the last two patches and send them separately, which may or may not make it in the merge window.

The omapfb driver is split into platform specific code for omap1, and driver code that is also specific to omap1.
Moving both parts into the driver directory simplifies the structure and avoids the dependency on certain omap machine header files.
As mach/lcd_dma.h can not be included from include/linux/omap-dma.h any more now, move the omap_lcd_dma_running() declaration into the omap-dma header, which matches where it is defined.

omapfb calls directly into the omap_set_dma_priority() function in the DMA driver. This prevents compile-testing omapfb on other architectures. Add an inline function next to the other ones for non-omap configurations.

To avoid relying on the mach/irqs.h header, stop using OMAP_LCDC_IRQ and INT_1610_SoSSI_MATCH directly in the driver code, but instead pass these as resources.

The register definitions in this header are used in at least four different places, with little hope of completely cleaning that up.
Split up the file into a portion that becomes a linux-wide header under include/linux/soc/ti/, and the parts that are actually only needed by board files.

From: Arnd Bergmann arnd@arndb.de
There are three remaining header files that are used by omap1 specific device drivers:
- mach/soc.h provides cpu_is_omapXXX abstractions - mach/hardware.h provides omap_read/omap_write functions and physical addresses - mach/mux.h provides an omap specific pinctrl abstraction
This is generally not how we do platform abstractions today, and it would be good to completely get rid of these in favor of passing information through platform devices and the pinctrl subsystem.
However, given that nobody is working on that, just move it one step forward by splitting out the header files that are used by drivers today from the machine headers that are only used internally.

The driver has always had a FIXME about this, and it seems like this trivial code move avoids a mach header inclusion, so just do it.
With that out of the way, and the header file inclusions changed to global files, the driver can also be compile-tested on other platforms.

There is only one board that uses the omap_cf driver, so moving the chipselect configuration there does not lead to code duplication but avoids the use of mach/tc.h in drivers.

omap2 stopped using this code with commit 8d39ff3d1696 ("ARM: OMAP2+: Remove unused legacy code for timer"), so just move it to mach-omap1 now, along with the other half of that driver.
BTW, if omap1 gains devicetree support, chances are that the drivers/clocksource/timer-ti-32k.c will be usable with minor modifications.
Regards,
Tony

It has been impossible to select this driver for six years without anyone noticing, so just kill it completely.

Most of the plat-omap/dma.c code is specific to the USB driver. Hide that code when it is not in use, to make it clearer which parts are actually still required.

Most of the plat-omap/dma.c code is specific to the USB driver.
The reason is simple: the omap_udc is the only driver which has not been ported to DMAengine. I had a patch if I recall to convert it, but I don't have a way to test it and the omap_udc sets some funky bits for DMA which we can not figure out on how to handle.
Hide that code when it is not in use, to make it clearer which parts are actually still required.

The legacy interface for omap-dma is only used on OMAP1, and the same is true for the non-DT case. Make both of these conditional on CONFIG_ARCH_OMAP1 being set to simplify the dependency.
The non-OMAP stub functions in include/linux/omap-dma.h are note needed any more either now, because they are only called on OMAP1.

No part of plat-omap/dma.c is called on omap2 any more, so anything omap2 specific in here can simply be removed.

No part of plat-omap/dma.c is called on omap2 any more, so anything omap2 specific in here can simply be removed.

From: Arnd Bergmann arnd@arndb.de
Most of the interface functions in plat/dma.c are only used from the USB driver, which is practically OMAP1 specific, except for compile testing.
The omap_get_plat_info(), omap_request_dma() and omap_free_dma() functions are never called on omap2 because of runtime checks.

The sram initialization code is the only shared omap1/2 code that is not a standalone driver, but it is very short. Having two copies of this code means some duplication of the sources, but actually saves object code size as it can be inlined better.

The sram initialization code is the only shared omap1/2 code that is not a standalone driver, but it is very short. Having two copies of this code means some duplication of the sources, but actually saves object code size as it can be inlined better.
FYI, the sram code should eventually be updated to use drivers/misc/sram.c, I recall there being some issues to deal with for PM related code though. Probably the PM related save and restore could be now handled with cpu_pm.

Tony

The address range 0xfee00000-0xfeffffff is used for PCI and PCMCIA I/O port mappings, but OMAP1 has its static mappings there as well.
Move the OMAP1 addresses a little higher to avoid crashing at boot.

This has the same problem I reported in 2019, with earlyprintk the system no longer boots:

The address range 0xfee00000-0xfeffffff is used for PCI and PCMCIA I/O port mappings, but OMAP1 has its static mappings there as well.
Move the OMAP1 addresses a little higher to avoid crashing at boot.
This has the same problem I reported in 2019, with earlyprintk the system no longer boots:
https://marc.info/?t=156530014200005&r=1&w=2Tested on OSK and SX1/qemu.
Thanks a lot for testing!
I managed to get to the bottom of this after just a few hours, and it turned out to be a simple math error on my end, as I got the alignment wrong, the offset has to be 0x00f00000 instead of 0x00fb0000 be section aligned. I made sure the kernel boots up (to the point of missing a rootfs) and uploaded the fixed branch.

Good to hear this got sorted out :)

The ISA I/O space handling in omap_cf is incompatible with PCI drivers in a multiplatform kernel, and requires a custom mach/io.h.
Change the driver to use pci_remap_iospace() like PCI drivers do, so the generic ioport access can work across platforms.
To actually use that code, we have to select CONFIG_PCI here.

Most of the header files are no longer referenced from outside arch/arm/mach-omap1, so move them all to that place directly and change their users to use the new location.
The exceptions are:
- mach/compress.h is used by the core architecture code - mach/serial.h is used by mach/compress.h
The mach/memory.h is empty and gets removed in the process, avoiding the need for CONFIG_NEED_MACH_MEMORY_H.

In a multiplatform randconfig kernel, one can have CONFIG_ARCH_OMAP1 enabled, but none of the specific SoCs. This leads to some build issues as the code is not meant to deal with this configuration at the moment:
arch/arm/mach-omap1/io.c:86:20: error: unused function 'omap1_map_common_io' [-Werror,-Wunused-function] arch/arm/mach-omap1/pm.h:113:2: error: "Power management for this processor not implemented yet" [-Werror,-W#warnings]
Use the same trick as on OMAP2 and guard the actual compilation of platform code with another Makefile ifdef check based on an option that depends on having at least one SoC enabled.
The io.c file still needs to get compiled to allow building device drivers with a dependency on CONFIG_ARCH_OMAP1.

In preparation for conversion of OMAP1 clocks to common clock framework, identify arch/arm/mach-omap1 local users of those clocks and update them to call clk_prepare_enable/clk_disable_unprepare() instead of just clk_enable/disable(), as required by CCF implementation of clock API.

Commit ef772f2ee31e ("ARM: OMAP: Fix CONFIG_DEBUG_LL") was supposed to fix low level debugging, most possibly by early enabling UART clocks. The fix actually introduced early reset of most bits of MOD_CONF_CTRL_0 register, with the exception of UART1 and UART2 clock related bits which were set high. However, UART1 clock bit can play different roles on different OMAP1 variants. On OMAP1610 it enables the clock as intended, but on OMAP1510 it switches the clock rate from 12 to 48 MHz. Even worth, for UART2 the bit changes its clock rate also on OMAP1610. As a result, UART rates set by a bootloader can be unintentionally changed early on kernel boot and low level debugging broken, not fixed. Besides, reset of all other bits was not justified.
Don't touch register bits not related to UART clocks. Also, don't touch the bit of UART2 clock. Make sure UART1 and UART3 are enabled early on relevant OMAP1610 machine types while preserving bootloader UART clock rates on others.

Since its introduction to the mainline kernel, omap1_uart_recalc() helper makes incorrect use of clk->enable_bit as a ready to use bitmap mask while it only provides the bit number. Fix it.

Drop them.

There are some OMAP1 clock code bits that have no effect: - crystal_type variable is set to 0 but never changed, then crystal_type == 2 condition is never true and ck_ref.rate never set to 19200000, - clk->ops->allow_idle() is called from omap_clk_enable_autoidle_all() but that op is not configured for any clock, then the function does nothing and the op field is not needed, - ENABLE_ON_INIT flag is set for some clocks but is never checked by any code, then not needed. Drop that code.

OMAP1 still uses its own implementation of standard clock API defined in include/linux/clk.h. Internals of that implementation are not visible outside OMAP1 directory. As a consequence, device drivers are not able to register clocks potentially provided by peripheral devices.
Drop OMAP1 implementation of the clock API and enable common clock framework. Modify the remaining low level code to be compatible with clock provider API and register the clocks with CCF.
Move initialisation of clocks to omap1_timer_init() to avoid memory allocation issues at early setup phase from where omap1_init_early() is called. Register the clocks after initialization of clock I/O registers, local clock pointers used by OMAP1 clock ops, and local .rate fields of clocks with no local implementation of .recalc ops, so CCF structures are populated with correct data during clock registration. Instead of enabling some of the registered clocks, flag them for CCF as critical. Introduce .is_enabled op using code that verifies hardware status of clock enablement, split out from implementation of .disable_unused op, so the latter is actually called by CCF for not requested but hardware enabled clocks. Add .round_rate ops where missing so .set_rate ops are called by CCF as expected. Since CCF allows parallel execution of .enable/.disable and .set_rate ops, protect registers shared among those groups of ops from concurrent access with spinlocks. Drop local debugfs support in favor of that provided by CCF.

Eventually there should be just separate clock controller instances for the clock registers banks, and then this should all disappear as the lock is instance specific. Anyways, that's probably best done as a separate changes later on.

With all the header files out of the way, and the clock driver converted to the common framework, nothing stops us from building OMAP together with the other platforms.
As usual, the decompressor support is a victim here, and is only available when CONFIG_DEBUG_LL is configured for the particular board.

This is the full series for converting OMAP1 to multiplatform, rebased from my 2019 attempt to do the same thing. The soc tree contains simpler patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which means we are getting closer to completing this for all ARMv5 platforms (I have patches for PXA, which is the last one remaining).
Janusz already tested the branch separately and did the missing work for the common-clk conversion after my previous approach was broken.
The fbdev, mmc and ASoC portion of Janusz' work already went into the corresponding maintainer tree, but I include them here for reference. Unless there are any objections, I would add the entire series to the for-next branch of the soc tree, but only send the first 36 patches early in the merge window. After everything else has made it in, I would rebase the last two patches and send them separately, which may or may not make it in the merge window.
Sounds like a good plan to me. I usually send the MMC pull-request on Mondays, the first day of the merge window.

Sounds good to me. I tested the current omap1-multiplatform-5.18 branch from mach-omap2 point of view, and things seem to work just fine for me. I don't currently have any omap1 hardware online to test with.
For the patches, please feel free to add:

The soc tree contains simpler patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which means we are getting closer to completing this for all ARMv5 platforms (I have patches for PXA, which is the last one remaining).
Janusz already tested the branch separately and did the missing work for the common-clk conversion after my previous approach was broken.
I tested the full series on the following OMAP1 boards: ams-delta, nokia770, osk, palmte and sx1 (QEMU only).
Apart from the earlyprintk breakage, everything seemed to work OK.
A minor note, zImage grows about 50 KB with a minimal kernel config. This is not yet critical, there's still about 7% headroom on 770 to the 2 MB bootloader limit on my setup. Also the decompression time is approaching the hardcoded watchdog timeout...

Nice, thanks a lot for testing!

I suspect that most of this is for the added devicetree code, and some more for the common-clk layer. For the omap1_defconfig, there is some hope to get part of the overhead back eventually by replacing board files with dts descriptions that are not part of the zImage itself, but it's unlikely to ever get smaller than it was.

With the updated patch 26 also earlyprintk now works, so if you still update the patches, feel free to add for the whole series:

I was just doing the merge, so I added the tag to the commit now.
There is now an "omap1/multiplatform-prep" branch that is part of arm/multiplatform, and I hope to not have to rebase that. I also have an arm/multiplatform-late branch with the remaining contents.
