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

2026-06-01T15:43:11+00:00

[ Upstream commit 52ac35b8a151446481496404af3a8e5e889b3c5a ] 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: abx500: Fix type of 'argument' variable

2026-05-23T11:03:20+00:00

[ Upstream commit 34006f77890d050e6d80cbee365b5d703c1140b4 ] The argument variable is assigned the return value of pinconf_to_config_argument(), which returns a u32. Change its type from enum pin_config_param to unsigned int to correctly store the configuration argument.

pinctrl: cy8c95x0: Avoid returning positive values to user space

[ Upstream commit 5ad32c3607cf241a1a2680cabd64cbcd757227aa ] When probe fails due to unclear interrupt status register, it returns a positive number instead of the proper error code. Fix this accordingly.

pinctrl: cy8c95x0: remove duplicate error message

[ Upstream commit 970dacb3b9f0fedbbbcfd7dbf1f4f22340b3f359 ] The pin control core is covered to report any error via message. The devm_request_threaded_irq() already prints an error message. Remove the duplicates. While at it, drop the info message as the same information about an IRQ in use can be retrieved differently.

pinctrl: mediatek: common: Fix probe failure for devices without EINT

[ Upstream commit 8f9f64c8f90dca07d3b9f1d7ce5d34ccd246c9dd ] Some pinctrl devices like mt6397 or mt6392 don't support EINT at all, but the mtk_eint_init function is always called and returns -ENODEV, which then bubbles up and causes probe failure. To address this only call mtk_eint_init if EINT pins are present. Tested on Xiaomi Mi Smart Clock x04g (mt6392).

pinctrl: equilibrium: fix warning trace on load

2026-03-25T10:05:38+00:00

[ Upstream commit 3e00b1b332e54ba50cca6691f628b9c06574024f ] The callback functions 'eqbr_irq_mask()' and 'eqbr_irq_ack()' are also called in the callback function 'eqbr_irq_mask_ack()'. This is done to avoid source code duplication. The problem, is that in the function 'eqbr_irq_mask()' also calles the gpiolib function 'gpiochip_disable_irq()' This generates the following warning trace in the log for every gpio on load.
