2020-02-21pinctrl: Use new GPIO_LINE_DIRECTIONMatti Vaittinen1-1/+4
Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0. Main benefit is to make it easier to see which values mean IN and which OUT. As a side effect this helps GPIO framework to change the direction defines to something else if ever needed. Please note that return value from get_direction call on pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have returned value 2 for direction INPUT.

2019-11-05pinctrl: use devm_platform_ioremap_resource() to simplify codeYueHaibing1-3/+1
devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

2019-09-30pinctrl: pic32: Pass irqchip when adding gpiochipLinus Walleij1-13/+12
We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For more info see drivers/gpio/TODO. For chained irqchips this is a pretty straight-forward conversion.

2019-08-05pinctrl: Remove dev_err() usage after platform_get_irq()Stephen Boyd1-3/+1
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2016-04-01pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_mapIrina Tirdea1-1/+1
Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since it does not depend on device tree despite the current name. This will enforce a consistent naming in pinctr-utils.c and will make it clear it can be called from outside device tree (e.g. from ACPI handling code).
