Subject: [PATCH v2 0/8] arm64: dts: qcom: sa8295p: Enable GPU
Date: Thu, 21 Dec 2023 20:39:21 -0800	[thread overview]
Message-ID: <20231220-sa8295p-gpu-v2-0-4763246b72c0@quicinc.com> (raw)

Due to the different PMIC configuration found in the SA8295P platform,
compared to SC8280XP, the VDD_GFX pads are supplied by an dedicated
MAX20411 LDO.

Support for expressing the regulator supply is added to the binding, the
support for enabling the parent supply for GX is added, the missing
gfx.lvl power-domain is dropped, and the DeviceTree is wired up to
enable the GPU in this configuration.

Changes in v2:
- Made gpucc binding accept either power-domain or vdd-gfx-supply
- Updated comment in gdsc_gx_do_nothing_enable()
- Added a comment for the /delete-property/ power-domains
- Fixed node and property sort order in dts
- Switched zap firmware to use mbn file
- Link to v1: https://lore.kernel.org/r/20231220-sa8295p-gpu-v1-0-d8cdf2257f97@quicinc.com
