pinctrl: armada-37xx: propagate error from armada_37xx_gpio_get()

pinctrl: armada-37xx: set GPIO output value before setting direction

2025-06-19T13:27:59+00:00

commit e6ebd4942981f8ad37189bbb36a3c8495e21ef4c upstream. Changing the direction before updating the output value in the OUTPUT_VAL register may result in a glitch on the output line if the previous value in the OUTPUT_VAL register is different from the one we want to set. In order to avoid that, update the output value before changing the direction.

pinctrl: armada-37xx: use correct OUTPUT_VAL register for GPIOs > 31

2025-06-19T13:27:59+00:00

commit 947c93eb29c2a581c0b0b6d5f21af3c2b7ff6d25 upstream. The controller has two consecutive OUTPUT_VAL registers and both holds output value for 32 GPIOs. Due to a missing adjustment, the current code always uses the first register while setting the output value whereas it should use the second one for GPIOs > 31. Add the missing armada_37xx_update_reg() call to adjust the register according to the 'offset' parameter of the function to fix the issue.

pinctrl: mvebu: Fix devinit_dove_pinctrl_probe function

[ Upstream commit c25478419f6fd3f74c324a21ec007cf14f2688d7 ] When an error occurs during the execution of the function __devinit_dove_pinctrl_probe, the clk is not properly disabled. Fix this by calling clk_disable_unprepare before return.

pinctrl: mvebu: Switch to use DEFINE_NOIRQ_DEV_PM_OPS() helper

2023-08-21T15:58:10+00:00

Since pm.h provides a helper for system no-IRQ PM callbacks, switch the driver to use it instead of open coded variant. Reviewed-by: Jonathan Cameron Reviewed-by: Paul Cercueil Link: https://lore.kernel.org/r/20230717172821.62827-9-andriy.shevchenko@linux.intel.com Signed-off-by: Andy Shevchenko
