[PATCH 0/2] ARM: dts: meson: two GPU fixes

[Martin Blumenstingl]

While switching over to the main mesa git repository I was testing
kmscube again. On my Meson8m2 board I noticed that two interrupts were
correctly set up. This didn't cause any errors so far because on my
setup the lima driver is using the "pp_bcast" interrupt instead of
ppX and ppmmuX.

While fixing the interrupt lines I also noticed that I accidentally
left the switch-delay property in there. That was needed at some
point to run the out-of-tree lima kernel driver. It's not required
anymore and it's not documented so drop it.

Target release: v5.2 (if possible because this is where the lima kernel
driver will land). No need to send it for v5.1-rcX because there lima
driver won't be part of v5.1.

[PATCH 1/2] ARM: dts: meson8: fix GPU interrupts and drop an undocumented property

[Martin Blumenstingl]

The interrupts in Amlogic's vendor kernel sources are all contiguous.
There are two typos leading to pp2 and pp4 as well as ppmmu2 and ppmmu4
incorrectly sharing the same interrupt line.
Fix this by using interrupt 170 for pp2 and 171 for ppmmu2.

Also drop the undocumented "switch-delay" which is a left-over from my
experiments with an early lima kernel driver when it was still
out-of-tree and required this property on Amlogic SoCs.

Queued as fixes for v5.2.  I'll submit when v5.2-rc1 comes out.

For now, they're in my tree (branch: v5.2/fixes) and included in my
for-next branch for some broader testing.

Thanks,

Kevin
