2016-12-30gpio: update my email addressJohn Crispin

2016-01-13gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs()Guenter Roeck
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.

2016-01-05gpio: mm-lantiq: use gpiochip data pointerLinus Walleij
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: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Cc: John Crispin <blogic@openwrt.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-01-20gpio: gpio-mm-lantiq: Use of_mm_gpiochip_removeRicardo Ribalda Delgado
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.

2015-01-20gpio: gpio-mm-lantiq: Use of_property_read_u32Ricardo Ribalda Delgado
Instead of parsing manually the shadow content, use the much simpler helper of_property_read_u32.

2014-10-20gpio: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2012-05-21GPIO: MIPS: lantiq: convert gpio-mm-lantiq to OF and of_mm_gpioJohn Crispin
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.
