Revert "pinctrl-amd: enable IRQ for WACF2200 touchscreen on Lenovo Yoga 7 14AGP11"

2026-05-29T22:00:33+00:00

This reverts commit 3812a9e84265a5cdd90d29fe8d97a023e91fb945.

The probe ordering fix in the following patch ensures amd_gpio_probe()
completes before i2c-designware probes AMDI0010:02, allowing the
existing amd_gpio_irq_enable() flow to work correctly. The manual IRQ
restoration added by this patch is therefore no longer needed.

pinctrl: mcp23s08: Read spi-present-mask as u8 not u32

2026-05-25T07:50:48+00:00

The binding (microchip,mcp23s08) specifies microchip,spi-present-mask
as uint8, but driver would read u32, causing type mismatch. Use
device_property_read_u8 to match binding spec, hardware (8 chips max),
& prevent probe failure.

pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init

2026-05-25T07:50:48+00:00

Regmap initialization triggers regcache_maple_populate() which attempts
SPI read to populate cache. SPI read requires mcp->dev and mcp->addr to
be set, without them, NULL pointer dereference occurs during probe.

Move initialization before mcp23s08_spi_regmap_init() call.

pinctrl-amd: enable IRQ for WACF2200 touchscreen on Lenovo Yoga 7 14AGP11

2026-05-13T07:34:55+00:00

On Lenovo Yoga 7 14AGP11 (83TD), the WACF2200 touchscreen controller
is wired via I2C2 (AMDI0010:02) with its interrupt on GPIO pin 157
(confirmed via ACPI _CRS GpioInt decode). After amd_gpio_irq_init()
clears all GPIO interrupts at boot, pin 157 is never re-enabled,
preventing the touchscreen from signalling the driver.

Windows keeps GPIO 157 INTERRUPT_ENABLE (bit 11) and INTERRUPT_MASK
(bit 12) set after initialisation. Add a DMI quirk to restore these
bits after amd_gpio_irq_init() on this hardware.

pinctrl: imx1: Allow parsing DT without function nodes

2026-05-11T19:55:23+00:00

The old format to define pinctrl settings for imx in DT has two hierarchy
levels. The first level are function device nodes. The second level are
pingroups which contain a property fsl,pins. The original ntention was to
define all pin functions in a single dtsi file and just reference the
correct ones in the board files.

The commit ("5fcdf6a7ed95e pinctrl: imx: Allow parsing DT without function
nodes") already make moden i.MX chip support flatten layout.

Make legacy chipes (more than 15 years) support this flatten layout also.

pinctrl: qcom: Fix wakeirq map by removing disconnected irqs for sm8150

2026-05-05T09:27:27+00:00

PDC interrupts 122-125 were meant for ibi_i3c wakeup but sm8150 do not
support i3c. GPIOs 39,51,88 and 144 are also connected to different PDC
pin and already reflected in the wake irq map.

Remove the unsupported wakeup interrupts from the map.

pinctrl: meson: amlogic-a4: fix deadlock issue

2026-04-28T09:50:13+00:00

Accessing the pinconf-pins sysfs node may deadlock.

pinconf_pins_show() holds pctldev->mutex, and the platform driver
calls pinctrl_find_gpio_range_from_pin(), which tries to acquire
the same mutex again, leading to a deadlock.

Use pinctrl_find_gpio_range_from_pin_nolock() to fix this issue.
