2024-08-05pinctrl: ti: ti-iodelay: Fix some error handling pathsChristophe JAILLET
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.

2024-07-25of: remove internal arguments from of_property_for_each_u32()Luca Ceresoli
The of_property_for_each_u32() macro needs five parameters, two of which are primarily meant as internal variables for the macro itself (in the for() clause). Yet these two parameters are used by a few drivers, and this can be considered misuse or at least bad practice. Now that the kernel uses C11 to build, these two parameters can be avoided by declaring them internally, thus changing this pattern: struct property *prop; const __be32 *p; u32 val; of_property_for_each_u32(np, "xyz", prop, p, val) { ... } to this: u32 val; of_property_for_each_u32(np, "xyz", val) { ... } However two variables cannot be declared in the for clause even with C11, so declare one struct that contain the two variables we actually need. As the variables inside this struct are not meant to be used by users of this macro, give the struct instance the noticeable name "_it" so it is visible during code reviews, helping to avoid new code to use it directly. Most usages are trivially converted as they do not use those two parameters, as expected. The non-trivial cases are: - drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway - drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the checks had to be replicated in a different way, making code more verbose and somewhat uglier, but I refrained from a full rework to keep as much of the original code untouched having no hardware to test my changes All the changes have been build tested. The few for which I have the hardware have been runtime-tested too.

On the RZ/G2L SoC family, the direction of the Ethernet TXC/TX_CLK signal is selectable to support an Ethernet PHY operating in either MII or RGMII mode. By default, the signal is configured as an input and MII mode is supported. The ETH_MODE register can be modified to configure this signal as an output to support RGMII mode. As this signal is by default an input, and can optionally be switched to an output, it maps neatly onto an `output-enable` property in the device tree.

2024-07-04pinctrl: renesas: rzg2l: Clean up and refactor OEN read/write functionsPaul Barker
The variable naming in the various OEN functions has been confusing. We were passing the _pin & bit variables from rzg2l_pinctrl_pinconf_get() and rzg2l_pinctrl_pinconf_set() as the offset & pin argument to the oen_read() and oen_write() functions. This doesn't make sense, the first of these isn't actually an offset and the second is not needed for RZ/V2H but leads to confusion with the bit variable used within these functions. To tidy this up, instead pass the _pin variable directly to the oen_read() and oen_write() functions with consistent naming. Then rzg3s_read_oen() and rzg3s_write_oen() can use macros to get the port and pin numbers it needs. Instead of passing the pin capabilities into oen_read() and oen_write(), check that the pin supports OEN before calling these functions. Also, merge rzg3s_oen_is_supported() into rzg3s_pin_to_oen_bit() to give a single translation function which returns an error if the pin doesn't support OEN. While we're here, remove an unnecessary branch and clarify the variable naming. Lastly, check that we are not dealing with a dedicated pin before calling RZG2L_PIN_ID_TO_{PORT,PIN}().
