2025-06-29arm: pinctrl: Define .mux_mask field for NXP's SoCLukasz Majewski
The commit e8a9521e649f ("vf500/vf610: synchronise device trees with linux") has synchronized U-Boot's DTS with v5.19 Linux kernel. It turned out that in Linux's upstream iomuxc node description the 'fsl,mux_mask' was missing, so the U-Boot's pinctrl driver for NXP's Vybrid SoC was not working properly. As by default the mux mask was set to 0, for example the vf610 based boards (like BK4) were bricked, due to misconfiguration of gpio at early boot stage. The fix for all NXP eligible boards is to define .mux_mask field for soc specific *pinctrl_soc_info structure and use it directly in pinctrl MMIO driver, without the need to read the "fsl,mux_mask" property from device tree. This change brings the NXP's pinctrl driver in U-Boot closer to Linux upstream one. Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Peng Fan <peng.fan@nxp.com> #for i.MX8ULP
2025-01-25pinctrl: imx: Split imx_pinctrl_set_state() into common and mmio partsMarek Vasut
Split imx_pinctrl_set_state() into imx_pinctrl_set_state_common() and imx_pinctrl_set_state_mmio(). The former does the common configuration parsing, the later does call imx_pinctrl_set_state_common() and then does pin configuration using either SCU or MMIO accesses. The SCU part is going to be moved out in follow up patches. This is a preparatory patch for follow up pinctrl drivers which do not use the MMIO accessors, but some other means, like SCU or otherwise. Those will call the common imx_pinctrl_set_state_common() function wrapped into some other imx_pinctrl_set_state_*() function, in a way similar to imx_pinctrl_set_state_mmio() does so for MMIO accesses. Update all imx_pinctrl_set_state_mmio() call sites to call imx_pinctrl_set_state_mmio() instead. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
2025-01-25pinctrl: imx: Rename imx_pinctrl_remove() to imx_pinctrl_remove_mmio()Marek Vasut
The current implementation of imx_pinctrl_remove() is specific to the MMIO accessor implementation, rename the function to imx_pinctrl_remove_mmio() to make this obvious. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
2025-01-25pinctrl: imx: Split imx_pinctrl_probe() into common and mmio partsMarek Vasut
Split imx_pinctrl_probe() into imx_pinctrl_probe_common() and imx_pinctrl_probe_mmio(). The former does the common setup, the later does the common setup and MMIO access configuration. The common setup can be used as-is for SCU based systems, update the pinctrl-imx8 to call only the common setup, update all the other pinctrl drivers to call imx_pinctrl_probe_mmio(). No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
2025-01-25pinctrl: imx: Inline struct imx_pinctrl_soc_info access into probeMarek Vasut
The probe function is identical across all the pinctrl drivers. Inline the imx_pinctrl_soc_info access into imx_pinctrl_probe() and drop all the duplicate probe functions. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
2025-01-25pinctrl: imx: Rename imx_pinctrl_ops to match driversMarek Vasut
Rename the structure instances to match driver names, so they can be easily looked up e.g. in objdump and readelf outputs. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
2025-01-25pinctrl: imx: Push imx_pinctrl_ops into drivers and staticizeMarek Vasut
Move imx_pinctrl_ops into drivers and staticize. This is preparatory patch for follow up pinctrl drivers which will not use this variant of imx_pinctrl_ops content. This should not change size, as most of the deployments compiled in one pinctrl driver anyway. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master.

2023-01-20global: Finish CONFIG -> CFG migrationTom Rini
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...
