822593f028 gpio:fix: Proper handling of GPIO subsystem parts at Samsung devices
Now proper GPIO parts numbering is handled at Samsung devices.
This fix is necessary for code using GPIO located at other banks
than first.

Test HW:
- Exynos4210 - Trats
- S5PC110 - goni

365d607033 gpio: Replace ARM gpio.h with the common API in include/asm-generic
ARM boards should use the generic GPIO API
This means changing gpio to unsigned type
Remove the unused gpio_toggle() function which is not part of the API
Comment that free should not modify pin state

fixed merge conflict in da8xx_gpio.c, tegra2_gpio.c, and
extended to the new mxs_gpio.c.

9f15bc0c1c i2c:gpio:s5p: I2C GPIO Software implementation (via soft_i2c)
This patch adds support for software I2C for GONI and Universal C210 reference targets.
It adds support for access to GPIOs by number, not as it is present,
by bank and offset.

ef5d9eb925 gpio:samsung s5p_ suffix add for GPIO functions
This change is driven by need of general gpio_* functions,
which as their parameter are accepting the GPIO pin number, NOT
block and pin.

This makes the code alike to omap, and allows for using more
generic frameworks (e.g. software I2C).

3bb6b037e8 SAMSUNG: make s5p common gpio functions
Because of s5pc1xx gpio is same as s5p seires SoC,
move gpio functions to drvier/gpio/
and modify structure's name from s5pc1xx_ to s5p_.
