Subject: [PATCH] dt-bindings: input: ti,ads7843: Allow SPI clock polarity
Date: Fri, 16 Oct 2026 17:31:31 -0300 [thread overview]
Message-ID: <20261016203131.454640-1-festevam@gmail.com> (raw)
imx27-eukrea-mbimxsd27-baseboard passes 'spi-cpol' in the ads7846
touchscreen node, which causes the following dt-schema warning:
imx27-eukrea-mbimxsd27-baseboard.dtb: ads7846@0 (ti,ads7846):
Unevaluated properties are not allowed (spi-cpol was unexpected)
Allow spi-cpol so the binding describes the existing configuration
without changing its SPI mode.
