Linus reports that some Renesas pin control sub-drivers are still including <linux/gpio.h> instead of <linux/gpio/driver.h>. As these sub-drivers don't need either, the includes can just be removed.

The checker failed to validate all enum IDs in the description of a register with fixed-width register fields, due to a miscalculation of the number of described states: each register field of n bits can have "1 << n" possible states, not "1". Increase SH_PFC_MAX_ENUMS accordingly, now more enum IDs are checked (SH-Mobile AG5 has more than 4000 enum IDs defined).

Validate consistency of the pin control tables for pins with I/O voltage capabilities. If a pin has I/O voltage register bits declarations through .pin_to_pocctrl(), the SH_PFC_PIN_CFG_IO_VOLTAGE flag should be set in the pin's configs, and vice versa.

Validate consistency of the pin control tables for pins with pull-up and/or pull-down capabilities. If a pin has bias register bits declarations in bias_regs[] or through .pin_to_portcr(), the corresponding SH_PFC_PIN_CFG_PULL* flags should be set in the pin's configs, and vice versa, and the .get_bias() and .set_bias() callbacks should be implemented.

Currently rcar_pin_to_bias_reg() takes a struct sh_pfc pointer, which is only available after the pin control driver has been initialized, thus preventing the checker from calling this function for validating consistency of the pin control tables. Fix this by replacing the parameter by a struct sh_pfc_soc_info pointer.

All implementations of the .pin_to_portcr() method implement the same conversion from Port Control Register offset to virtual address. Factor it out into the two callers. Remove the pfc parameter, as it is no longer used. Note that the failure handling in r8a7740_pin_to_portcr() is pro forma, as the function is never called with an invalid pin number.

The pfc parameter of the .pin_to_pocctrl() method was never used. It is a relic of the old I/O voltage handling before commit 8775306d ("pinctrl: sh-pfc: refactor voltage setting"). Remove the parameter, as it prevents the checker from calling this function for validating consistency of the pin control tables.
