2025-06-24pinctrl: canaan: k230: Fix order of DT parse and pinctrl registerZe Huang
Move DT parse before pinctrl register. This ensures that device tree parsing is done before calling devm_pinctrl_register() to prevent using uninitialized pin resources. Fixes: 545887eab6f6 ("pinctrl: canaan: Add support for k230 SoC") Reported-by: Yao Zi <ziyao@disroot.org> Signed-off-by: Ze Huang <huangze@whut.edu.cn> Link: https://lore.kernel.org/20250624-k230-return-check-v1-2-6b4fc5ba0c41@whut.edu.cn Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2025-06-24pinctrl: canaan: k230: add NULL check in DT parseZe Huang
Add a NULL check for the return value of of_get_property() when retrieving the "pinmux" property in the group parser. This avoids a potential NULL pointer dereference if the property is missing from the device tree node. Also fix a typo ("sintenel") in the device ID match table comment, correcting it to "sentinel".

2025-06-24pinctrl: berlin: fix memory leak in berlin_pinctrl_build_state()Yuan Chen
In the original implementation, krealloc() failure handling incorrectly assigned the original memory pointer to NULL after kfree(), causing a memory leak when reallocation failed.

2025-06-24pinctrl: sunxi: Fix memory leak on krealloc failureYuan Chen
In sunxi_pctrl_dt_node_to_map(), when krealloc() fails to resize the pinctrl_map array, the function returns -ENOMEM directly without freeing the previously allocated *map buffer. This results in a memory leak of the original kmalloc_array allocation.

2025-06-18pinctrl: Constify pointers to 'pinctrl_desc'Krzysztof Kozlowski
Pin controller core code only stores the pointer to 'struct pinctrl_desc' and does not modify it anywhere. The pointer can be changed to pointer to const which makes the code safer, explicit and later allows constifying 'pinctrl_desc' allocations in individual drivers.

2025-06-18pinctrl: amd: Constify pointers to 'pinctrl_desc'Krzysztof Kozlowski
Internal functions obtaining pointers to 'struct pinctrl_desc' do not modify the contents so they can be made pointers to const. This makes code safer, explicit and later allows constifying 'pinctrl_desc' in pinctrl core code.

Pinctrl drivers for K210, TB10X and ZYNQ do not reference any machine headers, thus can be compile tested for increased build coverage.

2025-06-18pinctrl: starfive: Allow compile testing on other platformsKrzysztof Kozlowski
Always descent to drivers/pinctrl/starfive/ because limiting it with SOC_STARFIVE is redundant since its Makefile doesn't build anything if no Starfive-specific pin control Kconfig options are enabled. This allows compile testing on other architectures with allyesconfig.
