* gpio: mm-lantiq: Fix typo in the newly added header filenameAndy Shevchenko2023-03-231-1/+1
| | | | | | | | | | The header with legacy struct of_mmio_gpio_chip and accompanying APIs is called legacy-of-mm-gpiochip.h. Remove repetitive '.h' at the end. Fixes: a99cc66807d6 ("gpiolib: split of_mm_gpio_chip out of linux/of_gpio.h") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
* gpiolib: split of_mm_gpio_chip out of linux/of_gpio.hArnd Bergmann2023-03-061-1/+1
| | | | | | | | | | | | | | This is a rarely used feature that has nothing to do with the client-side of_gpio.h. Split it out with a separate header file and Kconfig option so it can be removed on its own timeline aside from removing the of_gpio consumer interfaces.

| | | | | | | | | | | | 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: 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.
