[PATCH] drm/etnaviv: correct timeout calculation
by Lucas Stach 09 Mar '18

09 Mar '18

The old way did clamp the jiffy conversion and thus caused the timeouts to become negative after some time. Also it didn't work with userspace which actually fills the upper 32bits of the 64bit timestamp value. Fix this by using the solution developed and tested by Russell.

[PATCH] drm/etnaviv: etnaviv_sched: Staticize functions when possible

[PATCH 0/3] drm: Add LVDS decoder bridge
by Jacopo Mondi 09 Mar '18

09 Mar '18

Hello, this small series add a driver for transparent LVDS decoders, as Thine THC63LVD1024 device. The R-Car Gen3 V3M Eagle board feature such a converter, that has been so far not described as part of the display output pipeline. Now that a driver has been added, the Eagle DTS file has been updated to include the transparent decoder chip. So far so good, but currently the current DRM Bridge API do not provide support to query a mode from another bridge as it is possible to do on panel devices. In our case the LVDS decoder is connected to the output of R-Car DU lvds encoder (drivers/gpu/drm/rcar-du/rcar_lvds.c). As its 'mode_set' function shows, LVDS modes cannot be propagated from bridge to another bridge, but are instead inferred from the bus_format field of the panel's connector. It is my intention to propose an API extension to allow formats to be propagated through bridges, but knowing the DRM/KMS subsystem very superficially I would appreciate any pointer from more experienced developers. For Renesas side: The series is based on Laurent's drm/next/du branch with patches on top for: - Sergei: Enable PFC, I2c, GPIOs for r8a77970 - Sergei: Add support for r8a77970 in DU and add display device nodes in r8a77970 DTSI - Niklas: Connect DU LVDS output to HDMI bridge adv7511w in Eagle DTS - Sergei: fix video output on R8A77970 A base branch with these patches applied is available at git://jmondi.org/linux v3m/v4.16-rc3/base Tested on Eagle board, making sure DU probes and testing all available output modes (of which only a few are actually working, I suspect due to faulty mode propagation through DRM bridges).

[PATCH v3 00/16] Implement H3/H5 HDMI driver
by Jernej Skrabec 09 Mar '18

09 Mar '18

This series implements H3/H5 HDMI driver. It was tested on OrangePi 2 (H3), OrangePi Plus2e (H3) and OrangePi PC2 (H5) with many resolutions and it works well. Code is based on linux-next, next-20180228 tag. Best regards, Jernej Changes in v3: - Removed TCON patch to skip LVDS procesing - Added TCON patch to release exclusive clock lock - Minimal clock rate is now returned immediately in round_rate for NM PLLs Changes in v2: - Fixed build warning on arm64 - Fixed condition in determine_rate function in HDMI PHY clock driver - Added defines for polarity settings in HDMI PHY - Added patch to skip LVDS code path altogether if TCON doesn't support it. - round_rate for NM PLLs now rounds to minimal rate if requested rate is lower. - set_rate for NM PLLs doesn't fail if requested rate is lower than minimal (round_rate is called before which already guarantees that rate is not lower than minimal). Jernej Skrabec (16): clk: sunxi-ng: Add check for minimal rate to NM PLLs clk: sunxi-ng: h3: h5: Add minimal rate for video PLL clk: sunxi-ng: h3: h5: Allow some clocks to set parent rate clk: sunxi-ng: h3: h5: export CLK_PLL_VIDEO dt-bindings: display: sun4i-drm: Add compatibles for H3 HDMI pipeline drm/sun4i: Release exclusive clock lock when disabling TCON drm/sun4i: Add support for H3 display engine drm/sun4i: Add support for H3 mixer 0 drm/sun4i: Fix polarity configuration for DW HDMI PHY drm/sun4i: Add support for variants to DW HDMI PHY drm/sun4i: Move and expand DW HDMI PHY register macros drm/sun4i: Add support for H3 HDMI PHY variant drm/sun4i: Allow building on arm64 ARM: dts: sunxi: h3/h5: Add HDMI pipeline ARM: dts: sun8i: h3: Enable HDMI output on H3 boards ARM64: dts: sun50i: h5: Enable HDMI output on H5 boards .../bindings/display/sunxi/sun4i-drm.txt | 6 + arch/arm/boot/dts/sun8i-h3-bananapi-m2-plus.dts | 25 ++ arch/arm/boot/dts/sun8i-h3-beelink-x2.dts | 25 ++ arch/arm/boot/dts/sun8i-h3-libretech-all-h3-cc.dts | 25 ++ arch/arm/boot/dts/sun8i-h3-nanopi-m1.dts | 25 ++ arch/arm/boot/dts/sun8i-h3-orangepi-2.dts | 25 ++ arch/arm/boot/dts/sun8i-h3-orangepi-lite.dts | 25 ++ arch/arm/boot/dts/sun8i-h3-orangepi-one.dts | 24 ++ arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts | 25 ++ arch/arm/boot/dts/sunxi-h3-h5.dtsi | 108 ++++++ .../boot/dts/allwinner/sun50i-h5-orangepi-pc2.dts | 25 ++ .../dts/allwinner/sun50i-h5-orangepi-prime.dts | 25 ++ .../allwinner/sun50i-h5-orangepi-zero-plus2.dts | 25 ++ drivers/clk/sunxi-ng/ccu-sun8i-h3.c | 32 +- drivers/clk/sunxi-ng/ccu-sun8i-h3.h | 4 +- drivers/clk/sunxi-ng/ccu_nm.c | 7 + drivers/clk/sunxi-ng/ccu_nm.h | 27 ++ drivers/gpu/drm/sun4i/Kconfig | 2 +- drivers/gpu/drm/sun4i/Makefile | 1 + drivers/gpu/drm/sun4i/sun4i_drv.c | 1 + drivers/gpu/drm/sun4i/sun4i_tcon.c | 6 +- drivers/gpu/drm/sun4i/sun8i_dw_hdmi.h | 157 ++++++++- drivers/gpu/drm/sun4i/sun8i_hdmi_phy.c | 369 ++++++++++++++++++--- drivers/gpu/drm/sun4i/sun8i_hdmi_phy_clk.c | 132 ++++++++ drivers/gpu/drm/sun4i/sun8i_mixer.c | 12 + include/dt-bindings/clock/sun8i-h3-ccu.h | 2 + 26 files changed, 1070 insertions(+), 70 deletions(-) create mode 100644 drivers/gpu/drm/sun4i/sun8i_hdmi_phy_clk.c -- 2.16.2

[git pull] drm fixes for 4.16-rc5
by Dave Airlie 09 Mar '18

09 Mar '18

Hi Linus, There are a small set of sun4i and i915 fixes: sun4i: divide by zero, clock and LVDS fixes i915: 1 fix for perf and a 1 race fix However amdgpu is a bit more than we are normally comfortable with at this point, however it does fix a lot of display issues with the new DC code which result in black screens in various configurations along with some run of the mill gpu configuration fixes. I'm happy enough that the fixes are limited to the DC code and should fix a bunch of issues on the new raven ridge APUs that we are seeing shipped now. Thanks, Dave.
