pinctrl: nxp: Add i.MX94 daisy register offset

2025-09-26T12:51:21Z

Define the daisy register offset for i.MX94 at 0x608 within the iomuxc register space. This enables correct pad selection for daisy chain configuration on i.MX94 platforms. Signed-off-by: Jacky Bai Signed-off-by: Alice Guo Acked-by: Peng Fan

arm: pinctrl: Define .mux_mask field for NXP's SoC

2025-06-29T13:07:55Z

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 Reviewed-by: Peng Fan #for i.MX8ULP

firmware: scmi_agent: add SCMI pin control protocol support

2025-05-03T19:55:32Z

This patch adds SCMI pin control protocol support to make the pin controller driver based on SCMI, such as drivers/pinctrl/nxp/pinctrl-imx-scmi.c, can be bound to the SCMI agent device whose protocol id is 0x19. Signed-off-by: Alice Guo

pinctrl: nxp: add a pin controller driver based on SCMI pin control protocol

2025-05-03T19:55:32Z

This patch provides a pinctrl driver based on SCMI pin control protocol. Currently, only the PINCTRL_CONFIG_SET command is implemented. Signed-off-by: Ranjani Vaidyanathan Signed-off-by: Peng Fan Signed-off-by: Alice Guo Reviewed-by: Ye Li

pinctrl: imx: Split MMIO accessors into pinctrl-imx-mmio.c

2025-01-25T12:06:32Z

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. No functional change. Signed-off-by: Marek Vasut

pinctrl: imx: Fold imx_pinctrl_set_state_scu() from pinctrl-imx8.c

2025-01-25T12:06:32Z

The only user of the SCU pinctrl code is pinctrl-imx8.c , fold the entire pinctrl-scu.c code into pinctrl-imx8.c and remove the matching Kconfig symbols and Makefile entries. No functional change. Signed-off-by: Marek Vasut

pinctrl: imx: Split imx_pinctrl_set_state_scu() from imx_pinctrl_set_state_mmio()

2025-01-25T12:06:32Z

Call imx_pinctrl_set_state_common() from imx_pinctrl_scu_conf_pins(), rename imx_pinctrl_scu_conf_pins() to imx_pinctrl_set_state_scu(). 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

pinctrl: imx: Split imx_pinctrl_set_state() into common and mmio parts

2025-01-25T12:06:32Z

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

pinctrl: imx: Rename imx_pinctrl_remove() to imx_pinctrl_remove_mmio()

2025-01-25T12:06:32Z

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

pinctrl: imx: Split imx_pinctrl_probe() into common and mmio parts

2025-01-25T12:06:32Z

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
