[PATCH v2 2/2] arm: dts: nxp: imx: Add support for Apalis Evaluation Board v1.2

From: Hiago De Franco
Date: Wed Jan 24 2024 - 09:22:09 EST


From: Hiago De Franco <hiago.franco@xxxxxxxxxxx>

Add support for the new Apalis Evaluation Board v1.2. Because
only the imx6q-apalis-eval.dts was available, the imx6q-apalis-eval.dtsi
has been created which has common hardware configurations for v1.0, v1.1
and v1.2. Both imx6q-apalis-eval.dts and imx6q-apalis-eval-v1.2.dts
files include imx6q-apalis-eval.dtsi.

Versions 1.0 and 1.1 are compatible with each other and should
use imx6q-apalis-eval.dts file. Now for v1.2, the new device-tree file
should be used.

v2:
- Add missing off-on-delay-us property with 100ms to reg_3v3_mmc and
reg_3v3_sd.
- Fix startup-delay-us property from 100us (reg_3v3_mmc and reg_3v3_sd)
and 1ms (reg_can1 and reg_can2) to 10ms.
- Fix pinctrl mux from 0xb000 to 0x1b0b0.
