95c761705e gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs()
Commit 6aa7dbfa28 ("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.

6aa7dbfa28 gpio: mm-lantiq: use gpiochip data pointer
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().

da2382218c gpio: gpio-mm-lantiq: Use of_mm_gpiochip_remove
Since d621e8bae5 (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.

Instead of parsing manually the shadow content, use the much simpler
helper of_property_read_u32.

a36e9a1c5f GPIO: MIPS: lantiq: convert gpio-mm-lantiq to OF and of_mm_gpio
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.
