aa14b42d53 Exynos5800: Introduce new proid for Exynos5800
This patch intends to add a new proid for Exynos5800 which is a
variant of Exynos5420. Product id for Exynos5800 is 0x5422.
Both Exynos5420 and Exynos5800 are pin to pin compitable. This
gives us an advantage of reusing Exynos5420 clock, pinmux, memory
and other settings.

9e306f15c6 exynos4/4x12: gpio: use gpio extra base addresses
This patch adds extra gpio part addresses to exynos4
and exynos4x12_gpio_data arrays, which are required
since the gpio enum lists are linear

b8809e60cd dm: exynos: gpio: Convert to driver model
Convert the exynos GPIO driver to driver model. This implements the generic
GPIO interface but not the extra Exynos-specific functions.

903fd79564 dm: exynos: Tidy up GPIO headers
The wrong header is being included, thus requiring the code to re-declare
the generic GPIO interface in each GPIO header.

Fix this.

f6ae1ca058 S5P: Exynos: Add GPIO pin numbering and rename definitions
This patch includes following changes :
* Adds gpio pin numbering support for EXYNOS SOCs.
  To have consistent 0..n-1 GPIO numbering the banks are divided
  into different parts where ever they have holes in them.

* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
  These changes were done to enable cmd_gpio for EXYNOS and
  cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
  getting a error during compilation.

* Adds support for name to gpio conversion in s5p_gpio to enable
  gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
  to decode the input gpio name to gpio number.
  Example: SMDK5420 # gpio set gpa00

8475c869c3 s5p: gpio: change gpio coding method for s5p gpio.
Old s5p gpio coding method was not clean and was not working properly
for all parts and banks. New method is clean and easy to extend.

Gpio coding mask:
0x000000ff - pin number
0x00ffff00 - bank offset
0xff000000 - part number

393cb36199 S5PC2XX: Rename S5pc2XX to exynos
As per new naming convention for Samsung SoC's, all Cortex-A9 and Cortex-A15
based SoC's will be classified under the name Exynos. Cortex-A9 and Cortex-A15
based SoC's will be sub-classified as Exynos4 and Exynos5 respectively.

In order to better adapt and reuse code across various upcoming Samsung Exynos
based boards, all uses of s5pc210 prefix/suffix/directory-names are renamed in
this patch. s5pc210 is renamed as exynos4210 and S5PC210/s5pc210 suffix/prefix
are renamed as exynos4/EXYNOS4.
