Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

pinctrl: imx1: Allow parsing DT without function nodes

2026-05-11T19:55:23+00:00

The old format to define pinctrl settings for imx in DT has two hierarchy levels. The first level are function device nodes. The second level are pingroups which contain a property fsl,pins. The original ntention was to define all pin functions in a single dtsi file and just reference the correct ones in the board files. The commit ("5fcdf6a7ed95e pinctrl: imx: Allow parsing DT without function nodes") already make moden i.MX chip support flatten layout. Make legacy chipes (more than 15 years) support this flatten layout also.

pinctrl: imx: PINCTRL_IMX_SCMI should depend on ARCH_MXC

2026-03-10T09:12:25+00:00

i.MX95 SCMI firmware is only present on NXP i.MX94 and i.MX95 SoCs. Hence add a dependency on ARCH_MXC, to prevent asking the user about this driver when configuring a kernel without NXP i.MX SoC family support. While at it, relax the dependencies on ARM_SCMI_PROTOCOL and OF when compile-testing. Signed-off-by: Geert Uytterhoeven Reviewed-by: Peng Fan Signed-off-by: Linus Walleij

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

pinctrl: imx: Add support for NXP i.MX952

2026-01-07T14:14:53+00:00

The i.MX952 System Manager (SM) firmware supports the System Control Management Interface (SCMI) pinctrl protocol, similar to the i.MX95 SM. The base offset for the i.MX952 IOMUXC Daisy input register differs from that of the i.MX95. Update the pinctrl-imx-scmi driver to add support for i.MX952.

pinctrl: imx: Support NXP scmi extended mux config

2026-01-07T14:14:53+00:00

i.MX94 has special muxing options for certain pins. Their mux settings are not in IOMUXC module. i.MX System Manager Firmware includes new vendor defined pinctrl type to SCMI pinctrl driver to handle these pins. The MUX value field in the IOMUX table is extended to 16 bits where the lower 8 bits represent the current IOMUX value and the upper 8 bits represent the new extended mux added in i.MX94.

pinctrl: make struct pinfunction a pointer in struct function_desc

2025-09-08T12:22:41+00:00

We currently duplicate the entire struct pinfunction object in pinmux_generic_add_pinfunction(). While this is inevitable when the arguments come in split through pinmux_generic_add_function(), users of pinmux_generic_add_pinfunction() will typically pass addresses of structures in .rodata, meaning we can try to avoid the duplication with the help from kmemdup_const(). To that end: don't wrap the entire struct pinfunction in struct function_desc but rather just store the address.

pinctrl: constify pinmux_generic_get_function()

With all users of struct function_desc limited to only accessing it using the dedicated function and never modifying it, we can now constify the return value of pinmux_generic_get_function() treewide.

pinctrl: imx: don't access the pin function radix tree directly

2025-09-08T12:22:08+00:00

The radix tree containing pin function descriptors should not be accessed directly by drivers. There are dedicated functions for it. I suppose this driver does it so that the memory containing the function description is not duplicated but we're going to address that shortly so convert it to using generic pinctrl APIs.
