New drivers: - New driver for Renesas R8A779H0 also known as R-Car V4M. - New driver for the Awinic AW9523/B I2C GPIO expander.

Improvements: - The Nomadik pin control driver was for years re-used out of tree for the ST STA chips, and now the IP was re-used in a MIPS automotive SoC called MobilEyeq5, so it has been split in pin control and GPIO drivers so the latter can be reused by MobilEyeq5.

2024-03-06pinctrl: Add driver for Awinic AW9523/B I2C GPIO ExpanderAngeloGioacchino Del Regno3-0/+1137
The Awinic AW9523(B) is a multi-function I2C gpio expander in a TQFN-24L package, featuring PWM (max 37mA per pin, or total max power 3.2Watts) for LED driving capability. It has two ports with 8 pins per port (for a total of 16 pins), configurable as either PWM with 1/256 stepping or GPIO input/output, 1.8V logic input; each GPIO can be configured as input or output independently from each other. This IC also has an internal interrupt controller, which is capable of generating an interrupt for each GPIO, depending on the configuration, and will raise an interrupt on the INTN pin to advertise this to an external interrupt controller.

2024-02-29gpio: nomadik: request dynamic ID allocationThéo Lebrun1-18/+36
Move away from statically allocated GPIO IDs. Switch to dynamic ID allocation. Static IDs are deprecated because they cause issues when multiple GPIO controllers are to be found on the same platform. Add a bit of complexity to do pin number -> GPIO chip + offset. Previously, bank number and offsets were retrieved using division and remainder (bank size being constant 32). Now, to get the pin number matching a bank base, we must know the sum of ngpios of previous banks. This is done in find_nmk_gpio_from_pin() which also exposes the offset inside the bank. Also remove the assumption that bank sizes are constant. Instead of using NMK_GPIO_PER_CHIP as bank size, use nmk_gpio_chips[i]->ngpio.

2024-02-29gpio: nomadik: extract GPIO platform driver from drivers/pinctrl/nomadik/Théo Lebrun5-892/+21
Previously, drivers/pinctrl/nomadik/pinctrl-nomadik.c registered two platform drivers: pinctrl & GPIO. Move the GPIO aspect to the drivers/gpio/ folder, as would be expected. Both drivers are intertwined for a reason; pinctrl requires access to GPIO registers for pinmuxing, pull-disable, disabling interrupts while setting the muxing and wakeup control. Information sharing is done through a shared array containing GPIO chips and a few helper functions. That shared array is not touched from gpio-nomadik when CONFIG_PINCTRL_NOMADIK is not defined. Make no change to the code that moved into gpio-nomadik; there should be no behavior change following. A few functions are shared and header comments are added. Checkpatch warnings are addressed. NUM_BANKS is renamed to NMK_MAX_BANKS. It is supported to compile gpio-nomadik without pinctrl-nomadik. The opposite is not true.

2024-02-29gpio: nomadik: fix offset bug in nmk_pmx_set()Théo Lebrun1-2/+4
Previously, the statement looked like: slpm[x] &= ~BIT(g->grp.pins[i]); Where: - slpm is a unsigned int pointer; - g->grp.pins[i] is a pin number. It can grow to more than 32. The expected shift amount is a pin bank offset. This bug does not occur on every group or pin: the altsetting must be NMK_GPIO_ALT_C and the pin must be 32 or above. It might have occured. For example, in pinctrl-nomadik-db8500.c, pin group i2c3_c_2 has the right altsetting and pins 229 and 230.

The conversion to DEFINE_NOIRQ_DEV_PM_OPS() lost the ability of the compiler to optimize away the struct dev_pm_ops object when it is not needed. Fix this by replacing the use of pm_sleep_ptr() by a custom wrapper.

2024-02-21pinctrl: renesas: rzg2l: Add suspend/resume supportClaudiu Beznea1-4/+404
pinctrl-rzg2l driver is used on RZ/G3S which support deep sleep states where power to most of the SoC components is turned off. For this add suspend/resume support. This involves saving and restoring configured registers along with disabling clock in case there is no pin configured as wakeup sources. To save/restore registers 2 caches were allocated: one for GPIO pins and one for dedicated pins. On suspend path the pin controller registers are saved and if none of the pins are configured as wakeup sources the pinctrl clock is disabled. Otherwise it remains on. On resume path the configuration is done as follows: 1/ setup PFCs by writing to registers on pin based accesses 2/ setup GPIOs by writing to registers on port based accesses and following configuration steps specified in hardware manual 3/ setup dedicated pins by writing to registers on port based accesses 4/ setup interrupts. Because interrupt signals are routed to IA55 interrupt controller and IA55 interrupt controller resumes before pin controller, patch restores also the configured interrupts just after pin settings are restored to avoid invalid interrupts while resuming.

The pinctrl-rzg2l driver accesses gpio_chip.irq, which is available only if CONFIG_GPIOLIB_IRQCHIP=y, and uses APIs that are defined only if CONFIG_IRQ_DOMAIN_HIERARCHY=y (irq_chip_*_parent() APIs). On ARCH_RZG2L, CONFIG_IRQ_DOMAIN_HIERARCHY is selected anyway, e.g. by CONFIG_ARM_GIC_V3, but CONFIG_GPIOLIB_IRQCHIP is not (it is on R-Car). Make this explicit at the driver level for a clearer view of the dependencies.

Currently on irq_disable(), we are disabling gpio interrupt enable(ISEL). That means the pin is just gpio input and not gpio input interrupt any more. So, move configuring ISEL in rzg2l_gpio_child_to_parent_hwirq()/ rzg2l_gpio_irq_domain_free() so that the pin will be gpioint always even during irq_disable().
