The Aspeed pinconf data structures are split into 'conf' and 'map' types, where the 'conf' struct defines which register and bitfield to manipulate, while the 'map' struct defines what value to write to the register and bitfield. Both structs have a mask member, and the wrong mask was being used to tell the regmap which bits to update. A todo is to look at whether we can remove the mask from the 'map' struct.

Use function callbacks for SCU related functions in pinctrl-imx.c in order to support the scenario of PINCTRL_IMX is built in while PINCTRL_IMX_SCU is built as module, all drivers using SCU pinctrl driver need to initialize the SCU related function callback, and no need to check CONFIG_PINCTRL_IMX_SCU anymore, hence stub functions also can be removed.

Most, but not all, Renesas pin control drivers use the "sh-pfc" pin control framework. As of commit 8449bfa9e6a9f7ec ("pinctrl: sh-pfc: Collect Renesas related CONFIGs in one place"), the code for this framework is always built when Renesas SoC pin control support is enabled, regardless of whether the enabled pin control drivers need it or not. Fix this by reintroducing the CONFIG_SH_PFC symbol to control inclusion of the "sh-pfc" framework and its dependencies, and selecting it when needed. This reduces kernel size of a typical RZ/A1 or RZ/A2 kernel by more than 6 resp. 11 KiB.

The drivers/pinctrl/sh-pfc subdirectory was originally created to group pin control drivers for various Renesas SuperH and SH-Mobile platforms. However, the name "sh-pfc" no longer reflects its contents, as the directory now contains pin control drivers for Renesas SuperH, ARM32, and ARM64 SoCs. Hence rename the subdirectory from drivers/pinctrl/sh-pfc to drivers/pinctrl/renesas, and the related Kconfig symbol from PINCTRL_SH_PFC to PINCTRL_RENESAS. Rename the git branch in MAINTAINERS, too, for consistency. Signed-off-by:

For pins requiring software driven IO output operations, the RZ/A1 Pin Controller uses either the "output-high" or "output-low" DT property to enable the corresponding output buffer. The actual line value doesn't matter, as it is ignored. Commit 42556242 ("pinctrl: generic: Add output-enable property") introduced a new DT property for this specific use case. Update the RZ/A1 Pin Controller DT bindings and driver to use this new property instead. Preserve backwards compatibility with old DTBs in the driver, as this comes at a very small cost. Notes: - The DT binding examples already used the new property, - There are no upstream users of the old properties. Signed-off-by:

driver_deferred_probe_check_state() may return -ETIMEDOUT instead of -EPROBE_DEFER after all built-in drivers have been probed. This can cause issues for built-in drivers that depend on resources provided by loadable modules. One such case happens on Tegra where I2C controllers are used during early boot to set up the system PMIC, so the I2C driver needs to be a built-in driver. At the same time, some instances of the I2C controller depend on the DPAUX hardware for pinmuxing. Since the DPAUX is handled by the display driver, which is usually not built-in, the pin control states will not become available until after the root filesystem has been mounted and the display driver loaded from it. Fixes: bec6c0ec ("pinctrl: Remove use of driver_deferred_probe_check_state_continue()") Suggested-by:
