The data field of an of_device_id structure has type const void *, so there is no need for a const-discarding cast when putting const values into such a structure. Done using Coccinelle.

The return value of of_device_get_match_data has type const void *. The desc field of the pctl structure also has a const type, so there is no need for the const-discarding cast between them.

This driver creates a const structure that it stores in the data field of an of_device_id array. Adding const to the declaration of the location that receives the const value from the data field ensures that the compiler will continue to check that the value is not modified. Furthermore, the const-discarding cast on the extraction from the data field is no longer needed. Done using Coccinelle.

On some systems, some PCB traces attached to GpioInts are routed in such a way that they pick up enough interference to constantly (many times per second) trigger. Enabling glitch-filtering fixes this.

Pinctrl single should just show how many pins were found, the physical address is already in the dev information.

We generally leave the GPIO clock disabled, unless an interrupt is requested or we're accessing IO registers. We forgot to do this for the ->get_direction() callback, which means we can sometimes [1] get incorrect results [2] from, e.g., /sys/kernel/debug/gpio. Enable the clock, so we get the right results! [1] Sometimes, because many systems have 1 or mor interrupt requested on each GPIO bank, so they always leave their clock on. [2] Incorrect, meaning the register returns 0, and so we interpret that as "input".

Add support for pinctrl on MT7622 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. However, the IO core for the MT7622 SoC is completely distinct from anyone of previous MediaTek SoCs which already had support, such as the hardware internal, register address map and register detailed definition for each pin. Therefore, instead, the driver is being newly implemented by reusing generic methods provided from the core layer with GENERIC_PINCONF, GENERIC_PINCTRL_GROUPS, and GENERIC_PINMUX_FUNCTIONS for the sake of code simplicity and rid of superfluous code. Where the function of pins determined by groups is utilized in this driver which can help developers less confused with what combinations of pins effective on the SoC and even reducing the mistakes during the integration of those relevant boards. As the gpio_chip handling is also only a few lines, the driver also implements the gpio functionality directly through GPIOLIB.
