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 <[email protected]> Reviewed-by: Peng Fan <[email protected]> #for i.MX8ULP

2025-01-25pinctrl: imx: Split MMIO accessors into pinctrl-imx-mmio.cMarek Vasut
Split MMIO accessors into pinctrl-imx-mmio.c and build this file only if Kconfig symbol PINCTRL_IMX_MMIO is selected. Select PINCTRL_IMX_MMIO Kconfig symbol for all but pinctrl-imx8.c driver, which does not use the MMIO accessors. This reduces the amount of code compiled on platforms which do not use the code.

Get rid of the unnecessary ifdeffery in pinctrl-imx.h in the process. Remove all SCU support from pinctrl-imx.c imx_pinctrl_set_state_mmio() which makes that function a pure MMIO pinctrl configuration accessor. Update pinctrl-imx8.c to call imx_pinctrl_set_state_scu directly. No functional change. This patch is best viewed with git show -w due to indent change. Signed-off-by: Marek Vasut <[email protected]>
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 <[email protected]>

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().

2021-01-05dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIASSimon Glass
We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but in every other case we just use DM_. Update the alias macros to use the DM_ prefix. We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro is widely used and there is at least some benefit to indicating it us a U-Boot driver, particularly for code ported from Linux. So for now, let's keep that name. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <[email protected]>

2020-07-09core: add support for U_BOOT_DRIVER_ALIASWalter Lozano
Currently when using OF_PLATDATA the binding between devices and drivers is done trying to match the compatible string in the node with a driver name. However, usually a single driver supports multiple compatible strings which causes that only devices which its compatible string matches a driver name get bound. To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro, which generates no code at all, but allows an easy way to declare driver name aliases. Thanks to this, dtoc could be improve to look for the driver name based on its alias when it populates the U_BOOT_DEVICE entry.

2020-07-09drivers: rename drivers to match compatible stringWalter Lozano
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot.

This commit is necessary to be able to re-use the pinctrl code in early SPL to properly configure pins. The problem is that those "static" structures (without explicit initialization) are placed in the SDRAM area, which corresponds to u-boot proper (not even SPL). Hence, when one wants to configure pins before relocation via DTS/DM, the board hangs (imx6q SoC powered one) as only OCRAM area is available (0x009xxxxx). This commit prevents from this issue by moving the imx6_pinctrl_soc_info structure to data section (from BSS).
