pinctrl: sunxi: a523: Remove unneeded IRQ remuxing flag

2026-07-24T14:16:08+00:00

[ Upstream commit eaf84ff673409fa3dfc390c6afb53b641ee5acba ] The Allwinner A10 and H3 SoCs cannot read the state of a GPIO line when that line is muxed for IRQ triggering (muxval 6), but only if it's explicitly muxed for GPIO input (muxval 0). Other SoCs do not show this behaviour, so we added a optional workaround, triggered by a quirk bit, which triggers remuxing the pin when it's configured for IRQ, while we need to read its value. For some reasons this quirk flag was copied over to newer SoCs, even though they don't show this behaviour, and the GPIO data register reflects the true GPIO state even with a pin muxed to IRQ trigger. Remove the unneeded quirk from the A523 family, where it's definitely not needed (confirmed by experiments), and where it actually breaks, because the workaround is not compatible with the newer generation pinctrl IP used in that chip. Together with a DT change this fixes GPIO IRQ operation on the A523 family of SoCs, as for instance used for the SD card detection.

pinctrl: sunxi: fix regulator leak in sunxi_pmx_request() error path

2026-07-24T14:15:46+00:00

[ Upstream commit 334f7bcbdc79dc8e5b938ac3372453a5368221cf ] In the error path of sunxi_pmx_request(), the code calls regulator_put(s_reg->regulator) to release the regulator. However, s_reg->regulator is only assigned after a successful regulator_enable(). This causes a memory leak: the regulator obtained via regulator_get() is never properly released when regulator_enable() fails.

pinctrl: sunxi: use kcalloc() instead of kzalloc()

Use devm_kcalloc() in init_pins_table() and prepare_function_table() to gain built-in overflow protection, making memory allocation safer when calculating allocation size compared to explicit multiplication.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

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.
