2024-09-02pinctrl: madera: Simplify with dev_err_probe()Yan Zhen1-6/+3
Switch to use dev_err_probe() to simplify the error path and unify a message template. Using this helper is totally fine even if err is known to never be -EPROBE_DEFER. The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.

2024-09-02pinctrl: renesas: rzg2l: Introduce single macro for digital noise filter ↵Lad Prabhakar1-32/+20
configuration Support for enabling the digital noise filter, and support for configuring the noise filter stages (via the FILNUM register) and the sampling interval (via the FILCLKSEL register) are related: a pin supports either all or none of them. Hence simplify declaring digital noise filter support for a pin by using a single feature flag instead of three separate flags.

2024-08-23pinctrl: samsung: Use kmemdup_array instead of kmemdup for multiple allocationShen Lichuan1-2/+2
Let the kmemdup_array() take care about multiplication and possible overflows. Using kmemdup_array() is more appropriate and makes the code easier to audit.

2024-08-08pinctrl: samsung: Add support for pull-up and pull-downVishnu Reddy4-0/+126
Gpiolib framework has the implementation of setting up the PUD configuration for GPIO pins but there is no driver support. Add support to handle the PUD configuration request from the userspace in samsung pinctrl driver.

2024-08-05pinctrl: s32cc: add update and overwrite options when setting pinconfAndrei Stefanescu1-7/+23
The previous pinconf settings(made by the bootloader) need to be overwritten when configuring the pinctrl of a driver during the boot process. Configuring the bias of a GPIO at runtime (e.g. pull-up) needs to preserve the other settings unaltered. This patch introduces changes to differentiate between the two cases.

2024-08-05pinctrl: s32cc: configure PIN_CONFIG_DRIVE_PUSH_PULLAndrei Stefanescu1-0/+4
Previously, it was possible to only configure the open-drain for a pin. However, after a pin got configured with open-drain, there wasn't any way to disable it. Add the push-pull configuration in order to reverse the open-drain configuration.

2024-08-05pinctrl: s32cc: enable the input buffer for a GPIOAndrei Stefanescu1-9/+8
The IBE (input buffer enable) should be enabled for a GPIO. Reading the value will return the one from the input register, writing the value will return the one from the output register. This offers the flexibility to check if the value intended to be set matches the actual physical one.
