Wolfram Sang 4a3a950ee9 gpio: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Axel Lin f86b7c70bc gpio: clps711x: Add missing .owner to struct gpio_chip
Add missing .owner of struct gpio_chip. This prevents the
module from being removed from underneath its users.

Axel Lin 21708c991e gpio: clps711x: Add module alias to support module auto loading
commit 55fe14ab87 "GPIO: clps711x: Rewrite driver for using generic GPIO code"
allows this driver to be built as a module.
Thus add module alias to support module auto loading.

Alexander Shiyan e8b49e0712 gpio: clps711x: Use of_match_ptr()
There is no reason to keep the OF data if the driver was compiled
without DT support.

Hence of_match_ptr() is not needed.

Wei Yongjun 2cad6a8a4c GPIO: clps711x: use platform_device_unregister in gpio_clps711x_init()
platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

Alexander Shiyan a3b8d4a513 GPIO: Add support for GPIO on CLPS711X-target platform
The CLPS711X CPUs provide some GPIOs for use in the system. This
driver provides support for these via gpiolib. Due to platform
limitations, driver does not support interrupts, only inputs and
outputs.
