2020-12-04pinctrl: falcon: add missing put_device() call in pinctrl_falcon_probe()Yu Kuai1-5/+9
if of_find_device_by_node() succeed, pinctrl_falcon_probe() doesn't have a corresponding put_device(). Thus add put_device() to fix the exception handling for this function implementation.

2019-08-06pinctrl: falcon: Add of_node_put() before returnNishka Dasgupta1-1/+4
Each iteration of for_each_compatible_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in two places. Issue found with Coccinelle.

2018-09-14pinctrl: Include <linux/gpio/driver.h> nothing elseLinus Walleij1-1/+1
These drivers are GPIO drivers, and the do not need to use the legacy header in <linux/gpio.h>, go directly for <linux/gpio/driver.h> instead. Replace any use of GPIOF_* with 0/1, these flags are for consumers, not drivers. Get rid of a few gpio_to_irq() users that was littering around the place, use local callbacks or avoid using it at all. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-08-28pinctrl: Pass all configs to driver on pin_config_set()Sherman Yin1-27/+36
When setting pin configuration in the pinctrl framework, pin_config_set() or pin_config_group_set() is called in a loop to set one configuration at a time for the specified pin or group. This patch 1) removes the loop and 2) changes the API to pass the whole pin config array to the driver. It is now up to the driver to loop through the configs. This allows the driver to potentially combine configs and reduce the number of writes to pin config registers. All c files changed have been build-tested to verify the change compiles and that the corresponding .o is successfully generated.
