2020-11-17drm/selftests/test-drm_mm: Mark 'hole_end' as always_unusedLee Jones
In the macro drm_mm_for_each_hole() 'hole_end' is provided as a container for 'hole_start + pos->hole_size', but is not utilised in this use-case. We cannot simply delete the variable, so here we tell the compiler that we're intentionally discarding the read value.

2020-11-17drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP ↵Marc Zyngier
registers Removing the meson-dw-hdmi module and re-inserting it results in a hang as the driver writes to HDMITX_TOP_SW_RESET. Similar effects can be seen when booting with mainline u-boot and using the u-boot provided DT (which is highly desirable). The reason for the hang seem to be that the clocks are not always enabled by the time we enter meson_dw_hdmi_init(). Moving this call *after* dw_hdmi_probe() ensures that the clocks are enabled.

When used as DPI this display requires DE to be active low and pixel data to be output on the negative edge.

2020-11-16drm/panel: s6e63m0: Simplify SPI writingLinus Walleij
This writing code is equivalent to the spi_write() helper in the SPI framework. Insert a comment that this will always work fine since SPI buffers are in native endianness.

2020-11-15drm/gma500: Remove 2D accel codePatrik Jakobsson
2D acceleration is only available on PSB and MRST and very slow on both platforms. CPU acceleration is faster so don't bother with 2D accel anymore.

2020-11-15drm/gma500: Remove GTT roll supportPatrik Jakobsson
GTT roll support was used to accelerate fb panning on some machines. Unfortunately this never worked properly with multiple monitors and caused issues on others where the framebuffer wouldn't fit in stolen memory. Let's remove it!

The OnePlus 6/T devices use different panels however they are functionally identical with the only differences being the resolution. The panels also don't seem to be used by any other devices, just combine them into one driver.
