[PATCH v3 2/2] arm64: dts: imx95: Describe Mali G310 GPU
From: Marek Vasut <hidden>
Date: 2025-09-25 20:40:08
Also in:
dri-devel, imx, linux-devicetree
Subsystem:
arm/freescale imx / mxc arm architecture, the rest · Maintainers:
Frank Li, Sascha Hauer, Linus Torvalds
The instance of the GPU populated in i.MX95 is the G310, describe this
GPU in the DT. Include dummy GPU voltage regulator and OPP tables.

V2: - Drop regulator-{always,boot}-on from fixed-gpu-reg regulator
- Keep the GPU and GPUMIX always enabled
- Switch from fsl, to nxp, vendor prefix
- Fix opp_table to opp-table
- Describe IMX95_CLK_GPUAPB as coregroup clock
- Sort interrupts by their names to match bindings
V3: - Drop perf power domain
- Drop reset block controller
