pinctrl: renesas: rzg2l: Fix save/restore of {IOLH,IEN,PUPD,SMT} registers

2026-05-23T11:04:42+00:00

[ Upstream commit d9a60e367919752a1d398ebeba667f1e200fae1e ]

The rzg2l_pinctrl_pm_setup_regs() handles save/restore of
{IOLH,IEN,PUPD,SMT} registers during s2ram, but only for ports where all
pins share the same pincfg. Extend the code to also support ports with
variable pincfg per pin, so that {IOLH,IEN,PUPD,SMT} registers are
correctly saved and restored for all pins.

pinctrl: abx500: Fix type of 'argument' variable

2026-05-23T11:04:42+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: realtek: Fix function signature for config argument

2026-05-23T11:04:42+00:00

[ Upstream commit 1f5451844786ed203605528dca9e5d84ed378160 ]

The argument originates from pinconf_to_config_argument(), which returns a
u32. Therefore, the arg parameter should be an unsigned int instead of enum
pin_config_param.

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

2026-04-02T11:09:32+00:00

[ 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).

[ Upstream commit fd5bed798f45eb3a178ad527b43ab92705faaf8a ]

devm_add_action_or_reset() already invokes the action on failure,
