* gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs()Guenter Roeck2016-01-131-1/+2
| | | | | | | | | | | | Commit 6aa7dbfa2877 ("gpio: mm-lantiq: use gpiochip data pointer") replaces the use of container_of() with gpiochip_get_data(). However, the data pointer is not yet set by the time the save_regs function is called.

* gpio: mm-lantiq: use gpiochip data pointerLinus Walleij2016-01-051-6/+3
| | | | | | | | | | 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().

* gpio: gpio-mm-lantiq: Use of_mm_gpiochip_removeRicardo Ribalda Delgado2015-01-201-0/+18
| | | | | | | | | | | | | Since d621e8bae5ac9c67 (Create of_mm_gpiochip_remove), there is a counterpart for of_mm_gpiochip_add. This patch implements the remove function of the driver making use of it.

* gpio: gpio-mm-lantiq: Use of_property_read_u32Ricardo Ribalda Delgado2015-01-201-4/+3
| | | | | | | | | | | | | | Instead of parsing manually the shadow content, use the much simpler helper of_property_read_u32.

* gpio: drop owner assignment from platform_driversWolfram Sang2014-10-201-1/+0

* GPIO: MIPS: lantiq: convert gpio-mm-lantiq to OF and of_mm_gpioJohn Crispin2012-05-211-57/+89
| | | | | | | | | | | | | | | Implements OF support and convert to of_mm_gpio. By attaching hardware latches to the External Bus Unit (EBU) on Lantiq SoC, it is possible to create output only gpios. This driver configures a special memory address, which when written to, outputs 16 bit to the latches.

* GPIO: MIPS: lantiq: move gpio-stp and gpio-ebu to the subsystem folderJohn Crispin2012-05-211-0/+126
Move the 2 drivers from arch/mips/lantiq/xway/ to the subsystem and make them buildable. The following 2 patches will convert the drivers to OF.
