[PATCH v7 00/21] Add basic pinctrl drivers for JHB100 SoC

[Changhuang Liang]

The JHB100 SoC has 13 pinctrl domains - sys0, sys0h, sys1, sys2, per0, per1,
per2, per2pok, per3, adc0, adc1, emmc, and vga.

In the current series, we will only add the following pinctrl:
 - sys0, sys0h, sys1, sys2
 - per0, per1, per2, per2pok, per3

The remaining pinctrl will be implemented in future series.

This series depends on the series:

Change since v5:
PATCH 3/5/7/9/11/13/15/17/19/21:
- Change #interrupt-cells from 3 to 2.
- Change #gpio-cells from 3 to 2.
- Revert the gpio-ranges element from 5 to 4.

PATCH 4:
- Remove struct jhb100_gpio_bank
- Remove starfive_of_node_instance_match()
- Remove IRQF_SHARED in devm_request_irq()
- Remove the use of gpio_generic_chip_init() and switch to using the
  custom jhb100_gpio_get/set().
- Replace of_device_get_match_data() with device_get_match_data().
- Add a set of macros to simplify getting GPIO register offsets and masks.
	#define JHB100_NR_GPIOS_PER_BANK		32
	#define JHB100_BANK_OFFSET(n)			((n) * 4)
	#define JHB100_GPIO_BANK(gpio)			((gpio) / JHB100_NR_GPIOS_PER_BANK)
	#define JHB100_GPIO_MASK(gpio)			BIT((gpio) % JHB100_NR_GPIOS_PER_BANK)
	#define JHB100_GPIO_REG_OFFSET(gpio)		JHB100_BANK_OFFSET(JHB100_GPIO_BANK(gpio))
- Update jhb100_gpio_irq_handler() to support domains with more than 32 GPIOs.
