ACPI table on Intel Galileo Gen 1 has wrong pin number for IRQ resource of the I²C GPIO expander. Since we know what that number is and luckily have GPIO bases fixed for SoC's controllers, we may use a simple DMI quirk to match the platform and retrieve GpioInt() pin on it for the expander in question.

The pin control framework checks pin boundaries before calling the respective driver's callbacks. Hence no need to check for pin boundaries, the respective conditionals won't be ever true. Signed-off-by:

The Cypress CY8C95x0 chips have an internal EEPROM that defines initial configuration. It might be that bootloader or other entity wrote the platform related setup into it. Don't override it in the driver. Signed-off-by:

The Cypress GPIO expander is an I²C discrete component. Hence the platform may contain more than one of a such. Currently this has limitations in the driver due to same name used for all chips of a type. Replace this with device instance specific name. Signed-off-by:

Since recently, the kernel is nagging about mutable irq_chips: "not an immutable chip, please consider fixing it!" Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new helper functions and call the appropriate gpiolib functions. Signed-off-by:

Move gpio suspend/resume execution local to driver and let it execute as close as possible to the moment the machine specific PM code is executed (by setting it to .noirq member of dev_pm_ops). With this the at91_pinctrl_gpio_suspend()/at91_pinctrl_gpio_resume() calls were removed from arch/arm/mach-at91/pm.c and also a header has been removed. The patch has been checked on sama5d3_xplained, sam9x60ek, sama5d2_xplained, sama7g5ek boards. Signed-off-by:

When the driver want to disable the signal of the function, it doesn't need to query the state of the mux function's signal on a pin. The condition below will miss the disable of the signal: Ball | Default | P0 Signal | P0 Expression | Other -----+---------+-----------+-----------------------------+---------- E21 GPIOG0 SD2CLK SCU4B4[16]=1 & SCU450[1]=1 GPIOG0 -----+---------+-----------+-----------------------------+---------- B22 GPIOG1 SD2CMD SCU4B4[17]=1 & SCU450[1]=1 GPIOG1 -----+---------+-----------+-----------------------------+---------- Assume the register status like below: SCU4B4[16] == 1 & SCU4B4[17] == 1 & SCU450[1]==1 After the driver set the Ball E21 to the GPIOG0: SCU4B4[16] == 0 & SCU4B4[17] == 1 & SCU450[1]==0 When the driver want to set the Ball B22 to the GPIOG1, the condition of the SD2CMD will be false causing SCU4B4[17] not to be cleared.

The mt8186 contains 8 GPIO physical address bases that correspond to the 'reg-names' of the pinctrl driver. The 'reg-names' entries in bindings are ordered incorrectly, though. The system crashes due of an erroneous address when the regulator initializes. We fix the 'reg-names' for the pinctrl nodes and the pinctrl-mt8186 example in bindings. Fixes: 338e953f ("dt-bindings: pinctrl: mt8186: add pinctrl file and binding document") Co-developed-by:

Add pinctrl driver to support pin configuration for LPASS (Low Power Audio SubSystem) LPI (Low Power Island) pinctrl on SC8280XP. This IP is an additional pin control block for Audio Pins on top the existing SoC Top level pin-controller. Hardware setup looks like: TLMM GPIO[189 - 207] --> LPASS LPI GPIO [0 - 18] This pin controller has some similarities compared to Top level msm SoC Pin controller like 'each pin belongs to a single group' and so on. However this one is intended to control only audio pins in particular, which can not be configured/touched by the Top level SoC pin controller except setting them as gpios. Apart from this, slew rate is also available in this block for certain pins which are connected to SLIMbus or SoundWire Bus.
