pinctrl: driver for Conexant Digicolor CX92755 pin mapping
This adds pinctrl and gpio driver to the CX92755 SoC "General Purpose Pin Mapping" hardware block. The CX92755 is one SoC from the Conexant Digicolor series. Pin mapping hardware supports configuring pins as either GPIO, or up to 3 other "client select" functions. This driver adds support for pin muxing using the generic device tree binding, and a basic gpiolib driver for the GPIO functionality. This driver does not currently support GPIO interrupts, and pad configuration. v2: * Address review comments for Linus Walleij: - Add a pointer to pinctrl_desc in struct dc_pinmap - Drop the now redundant pinctrl_pin_desc field - Adapt dc_get_group_{name,pins} to these changes, and add a comment explaining the 1-to-1 pin-groups relation * Staticise dc_pmxops * Protect the GP_CLIENTSEL clct parameter with parenthesis Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
