pinctrl/amd: Remove the default de-bounce time

2016-09-07T06:34:48+00:00

commit 8cf4345575a416e6856a6856ac6eaa31ad883126 upstream. In the function amd_gpio_irq_enable() and amd_gpio_direction_input(), remove the code which is setting the default de-bounce time to 2.75ms. The driver code shall use the same settings as specified in BIOS. Any default assignment impacts TouchPad behaviour when the LevelTrig is set to EDGE FALLING.

pinctrl: amd: Use devm_pinctrl_register() for pinctrl registration

2016-04-21T07:23:21+00:00

Use devm_pinctrl_register() for pin control registration and clean error path. Signed-off-by: Laxman Dewangan Signed-off-by: Linus Walleij

pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map

2016-04-01T13:06:36+00:00

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).

pinctrl: amd:Add device HID for future AMD GPIO controller

2016-03-31T08:18:51+00:00

Add device HID AMDI0030 to match the AMD ACPI Vendor ID (AMDI) as registered in http://www.uefi.org/acpi_id_list, and the GPIO controller on future AMD paltform will use the HID instead of AMD0030. Signed-off-by: Wang Hongcheng Acked-by: Ken Xue Signed-off-by: Linus Walleij

pinctrl: Fix return value check in amd_gpio_probe()

2016-02-15T18:42:41+00:00

In case of error, the function devm_ioremap_nocache() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by: Wei Yongjun Signed-off-by: Linus Walleij

pinctrl: amd: use gpiochip data pointer

2016-01-05T13:14:52+00:00

This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Cc: Ken Xue Signed-off-by: Linus Walleij

gpio: change member .dev to .parent

2015-11-19T08:24:35+00:00

The name .dev in a struct is normally reserved for a struct device that is let us say a superclass to the thing described by the struct. struct gpio_chip stands out by confusingly using a struct device *dev to point to the parent device (such as a platform_device) that represents the hardware. As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

pinctrl/amd: Prepare amd_gpio_irq_handler for irq argument removal

2015-07-17T19:56:20+00:00

The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall. Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu Cc: Linus Walleij

pinctrl: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-07-17T19:56:20+00:00

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. Signed-off-by: Jiang Liu Cc: Linus Walleij Cc: linux-gpio@vger.kernel.org Signed-off-by: Thomas Gleixner
