pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe

2022-03-15T01:22:50Z

This node pointer is returned by of_parse_phandle() with refcount incremented in this function. Calling of_node_put() to avoid the refcount leak.

pinctrl: Bulk conversion to generic_handle_domain_irq()

2021-08-12T10:39:39Z

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq(). Acked-by: Krzysztof Kozlowski Acked-by: Linus Walleij Signed-off-by: Marc Zyngier

pinctrl: nomadik: Remove unused variable in nmk_gpio_dbg_show_one

Clang warns: drivers/pinctrl/nomadik/pinctrl-nomadik.c:952:8: warning: unused variable 'wake' [-Wunused-variable] bool wake; ^ 1 warning generated. There were two wake declarations added to nmk_gpio_dbg_show_one when converting it to use irq_has_action but only one is used within its scope. Remove the unused one so there is no more warning.

Pull irq updates from Thomas Gleixner: "This is the second attempt after the first one failed miserably and got zapped to unblock the rest of the interrupt related patches. A treewide cleanup of interrupt descriptor (ab)use with all sorts of racy accesses, inefficient and disfunctional code.

pinctrl: nomadik: db8500: Add more detailed LCD groups

We need a more granular distribution among funcion A and function B for the LCD pins for the Samsung GT-I9070. Provide some new pin groups so we can configure this phone properly. Link: https://lore.kernel.org/r/20201110232330.2242167-1-linus.walleij@linaro.org Signed-off-by: Linus Walleij

pinctrl: nomadik: Fix pull direction debug info

2020-08-27T08:25:17Z

The nomadik pinctrl hardware doesn't have any way to determine if the active pull is up or down. Reading the bit currently used to report if the pull is up/down indicates if the gpio input is reading high or low, it doesn't reflect the pull state. For this reason change the output from "pull up"/"pull down" to "pull enabled". This avoids confusing developers who were using the output to determine what the pull state is.
