pinctrl: imx: Return NULL if no group is matched and found

2025-05-09T07:50:36+00:00

[ Upstream commit e64c0ff0d5d85791fbcd126ee558100a06a24a97 ] Currently if no group is matched and found, this function will return the last grp to the caller, this is not expected, it is supposed to return NULL in this case.

pinctrl: freescale: fix COMPILE_TEST error with PINCTRL_IMX_SCU

[ Upstream commit 58414a31c5713afb5449fd74a26a843d34cc62e8 ] When PINCTRL_IMX_SCU was selected by PINCTRL_IMX8DXL or PINCTRL_IMX8QM combined with COMPILE_TEST on a non-arm platforms, the IMX_SCU dependency could not be enabled.

pinctrl: imx: Switch to LATE_SYSTEM_SLEEP_PM_OPS()

2024-08-23T16:15:52+00:00

Replace SET_LATE_SYSTEM_SLEEP_PM_OPS() with its modern LATE_SYSTEM_SLEEP_PM_OPS() alternative. The combined usage of pm_sleep_ptr() and LATE_SYSTEM_SLEEP_PM_OPS() allows the compiler to evaluate if the runtime suspend/resume() functions are used at build time or are simply dead code. This allows removing the __maybe_unused notation from the runtime suspend/resume() functions.

pinctrl: freescale: mxs: Fix refcount of child

2024-06-26T09:59:31+00:00

of_get_next_child() will increase refcount of the returned node, need use of_node_put() on it when done. Per current implementation, 'child' will be override by for_each_child_of_node(np, child), so use of_get_child_count to avoid refcount leakage.

The generic pinctrl-scmi.c driver could not be used for i.MX95 because i.MX95 SCMI firmware not supports functions, groups or generic 'Pin Configuration Type and Enumerations' listed in SCMI Specification. i.MX95 System Control Management Interface(SCMI) firmware only supports below pin configuration types which are OEM specific types: 192: PIN MUX 193: PIN CONF 194: DAISY ID 195: DAISY VAL To Support fsl,pins property together with SCMI OEM protocol, add this driver.
