Hello,
This patch series stems from subsystem-wide changes I wanted to compile-test with an ARM64 cross-compiler. My laziness to fire a 32-bit ARM build definitely resulted in more time being spent writing these patches, but hopefully they'll turn out to be useful for more people.
Patches 1/9 to 3/7 are fixes for compilation warnings on 64-bit platforms in the omapdrm and sti-drm drivers. They are a dependency for the Kconfig changes that follow to avoid introducing build warnings, but could also be merged before.
Patches 3/9 to 8/9 enable compilation of the imx-dcss, omapdrm, sti-drm and tegra-drm drivers on all architectures with COMPILE_TEST. I have tested compilation on arm64 and x86, with W=1. The patches are independent from each other, so they can be picked by their respective maintainers.
The last patch, 9/9, extends COMPILE_TEST support for the tilcdc driver to ARM64. The driver doesn't compile on x86 due to a missing __iowmb(), and I haven't taken the time to investigate how to solve this properly.
The main change since v1 is the extension of COMPILE_TEST to all platforms instead of only ARM and ARM64.
Please feel free to pick patches individually for the driver(s) you maintain.
