Add nodes for GPU (Mali 400) to Exynos4210 and Exynos4412. Describe the
GPU as much as possible however still few elements are missing:
1. Exynos4210 bus clock is not described in hardware manual therefore
the IP gate clock was provided,
2. Exynos4412: Not sure what to do with CLK_G3D clock responsible for
gating entire IP block (it is now being disabled as unused),
3. Regulator supplies on Trats board.
Limited testing on Odroid U3 (Exynos4412).
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Changes since v1:
1. Use samsung,exynos4210-mali compatible
2. Use CLK_G3D as bus clock (clock for entire IP block)
3. Remove some of operating points to match Mali in Tizen kernel.
Previously they were taken from datasheet but this information is too
generic.
4. Add 533 MHz opp to Exynos4412-prime.

Add nodes for GPU (Mali T760) to Exynos7. Current support for Exynos7
misses a lot, including proper clocks, power domains, frequency and
voltage scaling and cooling. However this still can provide basic GPU
description. Not tested on HW.

Enable support for Mali GPU with Panfrost and LIMA drivers. Most of
Exynos chipsets come with Mali GPUs:
1. Mali 400 (Exynos3250, Exynos4210, Exynos4412),
2. Mali T628 (Exynos542x).
As Mali GPU is quite popular among ARM vendors, other platforms will
benefit as well.

Enable support for Mali GPU with Panfrost and LIMA drivers. Most of
Exynos chipsets come with Mali GPUs:
1. Mali 400 (Exynos3250, Exynos4210, Exynos4412),
2. Mali T628 (Exynos542x).

It makes sense to enable lima for arm64 defconfig as well since it's
used on number of 64-bit Allwinner SoCs.

I wasn't aware that some of ARMv8 SoCs still use Utgard. In such case
it makes sense indeed, I will send a follow up.
Thanks for feedback!

Exynos5433-tm2 board support the exynos-bus device which
used the simple_ondmenad governor of devfreq.
Why do you remove this configuration from the defconfig?

It is selected by default by DRM_PANFROST. The difference is that
PANFROST selects it as module. The 'y' is chosen because of:
SCSI_UFSHCD [=y] && SCSI_LOWLEVEL [=y] && SCSI [=y] && SCSI_DMA [=y]

When I tried to find the history of CONFIG_DEVFREQ_GOV_SIMPLE_ONDEMAND
for defconfig, the following patch[1] added this configuration.
[1] b972ff75f2938c39e2205c23ea0e531d36b27f86
- "arm64: defconfig: Enable UFS on msm8996"
I think that this patch will affect the opration of 'USF on msm8998'.

Hi Chanwoo,
Thanks for the feedback. Unfortunately I do not see how removing a
dependency will affect that SCSI_UFSHCD. The
DEVFREQ_GOV_SIMPLE_ONDEMAND is still built in, exactly the same as
before...
Best regards,
Krzysztof
