Hello,
This patch series is a third attempt at removing the omapdrm and omapdss devices from platform code. Most of the patches from the previous version have been picked up already, this version contains all the leftovers.
The omapdss/omapdrm initialization code is quite a mess. The physical devices are instantiated from DT, but two virtual devices named omapdrm and omapdss are instanciated from platform code to pass SoC version information to the drivers through platform data.
The only remaining users of the platform data are the OMAP HDMI encoders. The series starts with a small cleanup in patch 01/11, followed by patches 02/11 to 05/11 that replace the SoC version with HDMI encoder version. Another small cleanup in patch 06/11 completes the HDMI encoders part of the series.
The next step is to remove the omapdss platform driver (for the virtual omapdss platform device, also known as core code, not to be confused with the omapdss_dss driver for the DSS hardware device). Patches 07/11 adds omapdrm platform device registration to the omapdss_dss driver to replace board code, and patch 08/11 finally removes the omapdss platform driver.
Note that registering the omapdrm platform device from within the omapdss_dss driver is a hack, but isn't worse than the current situation. Quite the contrary, given that the omapdrm device exists for the sole purpose of supporting the omapdrm/omapdss driver architecture, moving it out of platform code can be considered as (slightly) cleaner. In any case, it will be easier to refactor the code as everything is now isolated on the driver side.
Patches 09/11 and 10/11 remove the now unnecessary platform devices from platform code, and patch 11/11 removes the now unused omapdrm platform data structure.
A few patches touch the ARM mach-omap2 code, the OMAP sound driver and the OMAP fbdev driver. The ARM and sound patches have all been posted before and acked by Tony for mach-omap2 and Mark for sound for upstreaming through the drm tree. The fbdev change in patch 03/11 is new, and I'd like to get Bartlomiej's ack on it.
The series is based on top of "[PATCH v3 00/35] omapdrm: Deconstruct DSS features".
