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. Fixes: 727eb02e ("pinctrl: renesas: Switch to use DEFINE_NOIRQ_DEV_PM_OPS() helper") Signed-off-by:

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. Signed-off-by:

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(). Signed-off-by:

Add the missing port pins P19 to P28 for RZ/Five SoC. These additional pins provide expanded capabilities and are exclusive to the RZ/Five SoC. Couple of port pins have different configuration and are not identical for the complete port so introduce struct rzg2l_variable_pin_cfg to handle such cases and introduce the PIN_CFG_VARIABLE macro. The actual pin config is then assigned in rzg2l_pinctrl_get_variable_pin_cfg(). Add an additional check in rzg2l_gpio_get_gpioint() to only allow GPIO pins which support interrupt facility. While at define RZG2L_GPIO_PORT_PACK() using RZG2L_GPIO_PORT_SPARSE_PACK(). Update the gpio-ranges property in the RZ/Five SoC DTSI, as it must match the driver. Signed-off-by:

Currently we assume all the port pins are sequential ie always PX_0 to PX_n (n=1..7) exist, but on RZ/Five SoC we have additional pins P19_1 to P28_5 which have holes in them, for example only one pin on port19 is available and that is P19_1 and not P19_0. So to handle such cases include pinmap for each port which would indicate the pin availability on each port. As the pincount can be calculated based on pinmap drop this from RZG2L_GPIO_PORT_PACK() macro. Previously we had a max of 7 pins on each port but on RZ/Five Port-20 has 8 pins, so move the single pin configuration to BIT(63). Signed-off-by:

If the number of provided enum IDs in a variable width config register description does not match the expected number, the checker uses the expected number for validating the individual enum IDs. However, this may cause out-of-bounds accesses on the array holding the enum IDs, leading to bogus enum_id conflict warnings. Worse, if the bug is an incorrect bit field description (e.g. accidentally using "12" instead of "-12" for a reserved field), thousands of warnings may be printed, overflowing the kernel log buffer. Fix this by limiting the enum ID check to the number of provided enum IDs. Signed-off-by:

Commit d3aaa720 ("pinctrl: renesas: rzg2l: Add pin configuration support for pinmux groups") introduced the possibility to parse pin configuration for pinmux groups. It did that by calling rzg2l_map_add_config() at the end of rzg2l_dt_subnode_to_map() and jumping to the remove_group label in case rzg2l_map_add_config() failed. But if that happens, the mutex will already be unlocked, thus this it will lead to double mutex unlock operation. To fix this move the rzg2l_map_add_config() call just after all the name argument is ready and before the mutex is locked. There is no harm in doing this, as this only parses the data from device tree that will be further processed by pinctrl core code.
