Subject: [PATCH v2] dt-bindings: mmc: fsl-imx-mmc: Document the required clocks
Date: Thu, 22 Feb 2024 11:39:11 -0300 [thread overview]
Message-ID: <20240222143911.979058-1-festevam@gmail.com> (raw)
From: Fabio Estevam <festevam@denx.de>
The fsl-imx-mmc hardware needs two clocks to operate: ipg and per.
Document these required clocks.
This fixes the following schema warning:
imx27-apf27dev.dtb: mmc@10014000: Unevaluated properties are not allowed ('clock-names', 'clocks' were unexpected)
from schema $id: http://devicetree.org/schemas/mmc/fsl-imx-mmc.yaml#
Signed-off-by: Fabio Estevam <festevam@denx.de>
---
Changes since v2:
- None. Just fixed a typo in the dt list.
