From: Rahul Tanwar

Hi,

This series is to add pinctrl & GPIO controller driver for a new SoC.
Patch 1 adds pinmux & GPIO controller driver.
Patch 2 adds the corresponding dt bindings YAML document.

Patches are against Linux 5.4-rc1 at below Git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git

v7:
- Fix code quality/style related review concerns.
- Correct license id & data types used for some properties in dt bindings.
- Add possible values for drive-strength & slew rate in dt bindings.
- Rename compatible name to more self explanatory name in dt bindings.
- Fix make dt_binding_check reported errors. Ensure make dt_binding_check
passes.

v6:
- Fix code quality/style/readability related review concerns.
- Remove enum usage from pinmux property in dt bindings.

v5:
- Fix code style/readability related review concerns.
- Change data type of groups property to uint32-array in dt bindings.

v4:
- Correct data types for some pin config properties in dt bindings.
- Improve pattern regex as per review feedback in dt bindings.
- Remove eqbr_set_val() & set_drv_cur() reg update routines & instead
do reg updates in eqbr_pinconf_set() routine itself.
- Add locking in few ops where it was missing.
- Rename eqbr_gpio_desc struct to eqbr_gpio_ctrl and avoid using desc
in variable namings so as not to confuse with GPIO descriptors.
- Address code quality/convention/style related review concerns.

v3:
- Add locking for GPIO IRQ ops.
- Fix property naming mistake in dt bindings document.
- Address other code quality related review concerns.
- Fix a build error reported by kbuild test robot.
- Remove deleted structure fields from comments.

v2:
- Enable GENERIC_PINMUX_FUNCTIONS & GENERIC_PINCTRL_GROUPS and use core
provided code for pinmux_ops & pinctrl_ops. Remove related code from
the driver.
- Enable GENERIC_PINCONF & use core provided pinconf code. Remove related
code from the driver.
- Use GPIOLIB_IRQCHIP framework core code instead of implementing separtely
in the driver.
- Enable GPIO_GENERIC and switch to core provided memory mapped GPIO banks
design.
- Use standard pinctrl DT properties instead of custom made properties.
- Address review concerns for dt bindings document.
- Address code quality related review concerns.

v1:
- Initial version.
