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

pinctrl: imx: Inline struct imx_pinctrl_soc_info access into probe

2025-01-25T12:06:32Z

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

pinctrl: imx: Drop .remove callback for SCU variant

2025-01-25T12:06:32Z

The return callback for SCU variant of the pinctrl drivers does nothing but returns 0. Remove the return callback from the SCU driver itself, that has the same effect. No functional change. Signed-off-by: Marek Vasut

pinctrl: imx: Rename imx_pinctrl_ops to match drivers

2025-01-25T12:06:32Z

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

pinctrl: imx: Push imx_pinctrl_ops into drivers and staticize

2025-01-25T12:06:32Z

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
