Hi Peng,
Subject: [PATCH v2 07/11] imx: tpc70: dts: Add TPC70 board (imx6q based) device tree description
This commit defines the TPC70 imx6q board with device tree description.
Is the imx6q-kp.dtsi usable for this board from Linux kernel?
The imx6q-kp.dtsi is defined in the Linux kernel [1].
However, not all features - like backlight, CAN, etc. are needed in U-Boot. To reduce SPL footprint, as the TPC70 is the first board (from i.MX6Q family of SoCs) which uses only DM in SPL and U-Boot proper, only the necessary subset of [1] was added to U-Boot.
Note:
[1] - https://elixir.bootlin.com/linux/v5.2.8/source/arch/arm/boot/dts/imx6q-kp.dt...
Right, and that's what we have CONFIG_OF_SPL_REMOVE_PROPS for, yes?
