Subject: [PATCH] arm64: dts: imx8mp-debix-model-a: Remove USB hub reset-gpios
Date: Fri, 29 Sep 2023 10:11:23 -0300 [thread overview]
Message-ID: <20230929131123.651260-1-festevam@gmail.com> (raw)
From: Fabio Estevam <festevam@denx.de>
The SAI2_TXC pin is left unconnected per the imx8mp-debix-model-a
schematics:
https://debix.io/Uploads/Temp/file/20230331/DEBIX%20Model%20A%20Schematics.pdf
Also, the RTS5411E USB hub chip does not have a reset pin.
Remove this pin description to properly describe the hardware.
This also fixes the following schema warning:
hub@1: 'reset-gpios' does not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/usb/realtek,rts5411.yaml#
Fixes: 0253e1cb6300 ("arm64: dts: imx8mp-debix: add USB host support")
