Commit b681af0bc1cc ("drm: panfrost: add optional bus_clock")
added an optional bus_clock to support Allwinner H6 T-720 GPU.
Increase the max clock items in the dt-binding to reflect this.
Bifrost GPU in Rockchip RK3568 SoCs also has a core and a bus clock
and it gets added here in a (very) similar way it was done for
allwinner,sun50i-h6-mali compatible in arm,mali-midgard binding.

That's midgard and this is bifrost... Driver changes are somewhat
irrelevant.

I guess that one is insufficient.

Rockchip SoCs RK3566 and RK3568 have a Mali Gondul core
which is based on the Bifrost architecture. It has
one shader core and two execution engines.
Quoting the datasheet:
Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency

RK356x SoCs have a second thermal sensor for the GPU:
This adds the cooling map / trip points for it to make use of it's
contribution as a cooling device.

I'm playing with 5.16 mainline on rk3566 based tvbox (x96-x6)
Box boots and I have working SD card, Eth, HDMI.
I applied this series as I want to get GPU working but I'm getting:
[ 3.169144] panfrost fde60000.gpu: get clock failed -517
[ 3.169646] panfrost fde60000.gpu: clk init failed -517

Maybe you have some hints here?

517 is EPROBE_DEFER, which implies it's waiting for the relevant clock
provider to show up. I see from patch #2 that SCMI is involved, so I'd
check that that's working and you have CONFIG_COMMON_CLOCK_SCMI enabled.

Robin,
Many thx!
Indeed issue was with SCMi CLK.
Now i see:
[ 3.092350] panfrost fde60000.gpu: clock rate = 594000000
[ 3.092906] panfrost fde60000.gpu: bus_clock rate = 500000000
[ 3.138340] panfrost fde60000.gpu: clock rate = 594000000
[ 3.138904] panfrost fde60000.gpu: bus_clock rate = 500000000
[ 3.171244] panfrost fde60000.gpu: clock rate = 594000000
[ 3.171888] panfrost fde60000.gpu: bus_clock rate = 500000000
good.
(unfortunately mesa 21.3.4 still goes with llvmpipe but this seems to be other issue i need to investigate)
thx again!
