The new compatible string "microchip,sam9x75-xlcdc" is defined for sam9x75 variant of the sam9x7 SoC family.The is_xlcdc flag under driver data helps to differentiate the XLCDC and existing HLCDC code within the same driver. changes in v2: * Change the driver compatible name from "microchip,sam9x7-xlcdc" to "microchip,sam9x75-xlcdc". * Move is_xlcdc flag to driver data. * Remove unsed Macro definitions. * Add co-developed-bys tags * Replace regmap_read() with regmap_read_poll_timeout() call * Split code into two helpers for code readablitity.
