Input: mms114 - convert bindings to YAML and extend
This converts the Melfas MMS114 bindings and extend like this: - Require nodename touchscreen@ (this seems to be the case for all in-tree DTS files) - Add the mms134s and mms136 compatibles - Add the avdd and vdd power supplies - Define the I2C clock frequency property Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20210330201233.2360006-1-linus.walleij@linaro.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
