Revert "pinctrl: s32cc: implement GPIO functionality"

2026-07-31T22:06:02Z

This reverts commit 94cb9e8f270797e489633cfa53d2d44afecb8bef. This collides with orthogonal changes in the GPIO tree, we need to rebase it and apply it to the GPIO tree instead. Signed-off-by: Linus Walleij

pinctrl: s32cc: fix unmet dependency for PINCTRL_S32CC

2026-07-25T09:47:48Z

Currently, PINCTRL_S32G2 selects PINCTRL_S32CC which needs GPIOLIB, without selecting or depending on GPIOLIB. However, other similar options in this subsystem actually select GPIOLIB instead of depending, so I think we can do the same here. This unmet dependency was found by kconfirm, a static analysis tool for Kconfig.

pinctrl: s32cc: implement GPIO functionality

2026-07-01T10:33:18Z

The updated SIUL2 block groups pinctrl, GPIO data access and interrupt control within the same hardware unit. The SIUL2 driver is therefore structured as a monolithic pinctrl/GPIO driver. GPIO data access and direction handling are implemented using the gpio-regmap library backed by a virtual regmap. The virtual regmap translates the gpio-regmap register model to the underlying SIUL2 registers: MSCR for direction, PGPDI for input values and PGPDO for output values. The existing pinctrl GPIO callbacks are used for the request/free path: they switch the pad to GPIO mode on request and restore the previous MSCR configuration when the GPIO is released. This change came as a result of upstream review in the following series: https://lore.kernel.org/linux-gpio/20260120115923.3463866-4-khristineandreea.barbulescu@oss.nxp.com/T/#m543c9edbdde74bdc68b6a2364e8b975356c33043 https://lore.kernel.org/all/20260504131148.3622697-7-khristineandreea.barbulescu@oss.nxp.com/ Support both SIUL2 DT layouts: - legacy pinctrl-only binding - extended pinctrl/GPIO/irqchip binding Reviewed-by: Linus Walleij Signed-off-by: Andrei Stefanescu Signed-off-by: Khristine Andreea Barbulescu Reviewed-by: Bartosz Golaszewski Link: https://lore.kernel.org/linux-gpio/20260120115923.3463866-4-khristineandreea.barbulescu@oss.nxp.com/T/#m543c9edbdde74bdc68b6a2364e8b975356c33043 Link: https://lore.kernel.org/all/20260504131148.3622697-7-khristineandreea.barbulescu@oss.nxp.com/ Signed-off-by: Linus Walleij

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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
