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: k210: Use devm_clk_get_enabled() helpersWang Jianzheng1-27/+8
The devm_clk_get_enabled() helpers: - call devm_clk_get() - call clk_prepare_enable() and register what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the calls to clk_disable_unprepare().

Splitting error messages across multiple lines makes it harder to find them in the kernel sources. Fix this by joining the messages.

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. This patch removes the PIN_CFG_FILNUM and PIN_CFG_FILCLKSEL configuration macros and renames PIN_CFG_FILONOFF to PIN_CFG_NF.

2024-08-05pinctrl: ti: ti-iodelay: Fix some error handling pathsChristophe JAILLET1-31/+21
In the probe, if an error occurs after the ti_iodelay_pinconf_init_dev() call, it is likely that ti_iodelay_pinconf_deinit_dev() should be called, as already done in the remove function. Also in ti_iodelay_pinconf_init_dev(), if an error occurs after the first regmap_update_bits() call, it is also likely that the deinit() function should be called. The easier way to fix it is to add a devm_add_action_or_reset() at the rigtht place to have ti_iodelay_pinconf_deinit_dev() called when needed. Doing so, the .remove() function can be removed, and the associated platform_set_drvdata() call in the probe as well.

2024-08-04pinctrl: samsung: Use of_property_present()Rob Herring (Arm)1-4/+4
Use of_property_present() to test for property presence rather than of_find_property(). This is part of a larger effort to remove callers of of_find_property() and similar functions. of_find_property() leaks the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.

Add the Mobileye EyeQ5 pin controller driver. It belongs to a syscon region called OLB and gets spawned as auxiliary device to the platform driver for clock. Existing pins and their function live statically in the driver code rather than in the devicetree, see compatible match data.
