2023-12-04pinctrl: qcom: fail to retrieve configuration from invalid pin groupsRichard Acayan
The pinconf-groups debugfs file dumps each valid configuration item of all pin groups. Some platforms and devices may have pin groups which cannot be accessed, according to commit 691bf5d5a7bf ("pinctrl: qcom: Don't allow protected pins to be requested"). Fail for each configuration item of an invalid pin group by checking the GPIO chip's valid mask. The validity of the pin group cannot be checked in the generic pinconf dump (function "pinconf_generic_dump_one"), as it does not directly interact with the gpiochip or the pinmux callbacks (which would give it access to the request callback). Instead, an entry contains the ID and name of the pingroup with no properties when all items fail.

In the STMicroelectronics STM32 driver, stm32_gpio_direction_output() ignores the result of pinctrl_gpio_direction_output() for no good reason. Let's propagate errors from pinctrl_gpio_direction_output() upstream... Found by Linux Verification Center (linuxtesting.org) with the Svace static analysis tool.

2023-11-24pinctrl: realtek: Fix logical error when finding descriptorTzuyi Chang
The pin descriptor should be returned if the name has been found in the descriptor table. Remove the negation in the if statement for accurate retrieval.

2023-11-22pinctrl: intel: use the correct _PM_OPS() export macroRaag Jadav
Since we don't have runtime PM handles here, we should be using EXPORT_NS_GPL_DEV_SLEEP_PM_OPS() macro, so that the compiler can discard it in case CONFIG_PM_SLEEP=n.

2023-11-16pinctrl: lochnagar: Don't build on MIPSCharles Keepax
MIPS appears to define a RST symbol at a high level, which clashes with some register naming in the driver. Since there is currently no case for running this driver on MIPS devices simply cut off the build of this driver on MIPS.
