[PATCH 2/2] dt-bindings: input: Update documentation for clps711x-keypad

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since the driver switched to using the syscon_regmap_lookup_by_phandle()
function, we need to specify the phandle for the driver. This patch
updates the driver binding documentation for these changes.
