The MAX77802 is a chip that contains regulators, 2 32kHz clocks, a RTC and an I2C interface to program the individual components. The are already DT bindings for the regulators and clocks and these reference to a bindings/mfd/max77802.txt file, that didn't exist, for the details about the PMIC. Signed-off-by: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx> --- Changes in v4: - Reword section about max77802 clock and regulator DT binding docs. Suggested by Lee Jones. - Align max77802 mfd required properties. Suggested by Lee Jones. Changes in v3: - Add Krzysztof Kozlowski Reviewed-by tag to patch #3. - Capitalise all acronyms. Suggested by Lee Jones. - Use relative path to refer other bindings. Suggested by Lee Jones. - Use IRQ_TYPE_NONE instead of 0 in example. Suggested by Lee Jones. Changes in v2: - Use the correct "maxim,max77802" compatible string. Suggested by Krzysztof Kozlowski - Use a pmic generic node name for the max77802 node example. Suggested by Sergei Shtylyov.
