pinctrl: Get rid of duplicate of_node assignment in the drivers

2021-12-16T03:18:30Z

GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove these assignment all at once. For the details one may look into the of_gpio_dev_init() implementation.

pinctrl: amd: Fix wakeups when IRQ is shared with SCI

2021-11-16T01:19:14Z

On some Lenovo AMD Gen2 platforms the IRQ for the SCI and pinctrl drivers are shared. Due to how the s2idle loop handling works, this case needs an extra explicit check whether the interrupt was caused by SCI or by the GPIO controller. To fix this rework the existing IRQ handler function to function as a checker and an IRQ handler depending on the calling arguments.

pinctrl: amd: disable and mask interrupts on probe

2021-10-16T21:56:59Z

Some systems such as the Microsoft Surface Laptop 4 leave interrupts enabled and configured for use in sleep states on boot, which cause unexpected behaviour such as spurious wakes and failed resumes in s2idle states. As interrupts should not be enabled until they are claimed and explicitly enabled, disabling any interrupts mistakenly left enabled by firmware should be safe.

pinctrl: amd: Handle wake-up interrupt

2021-09-16T22:48:45Z

Enable/disable power management wakeup mode, which is disabled by default. enable_irq_wake enables wakes the system from sleep. Hence added enable/disable irq_wake to handle wake-up interrupt.

pinctrl: amd: Add irq field data

2021-09-16T22:48:45Z

pinctrl_amd use gpiochip_get_data() to get their local state containers back from the gpiochip passed as amd_gpio chip data. Hence added irq field data to get directly using amd_gpio chip data.

pinctrl: Bulk conversion to generic_handle_domain_irq()

2021-08-12T10:39:39Z

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq(). Acked-by: Krzysztof Kozlowski Acked-by: Linus Walleij Signed-off-by: Marc Zyngier

pinctrl/amd: Add device HID for new AMD GPIO controller

2021-05-25T15:09:48Z

Add device HID AMDI0031 to the AMD GPIO controller driver match table. This controller can be found on Microsoft Surface Laptop 4 devices and seems similar enough that we can just copy the existing AMDI0030 entry.
