[PATCH v2 0/2] ARM: sun8i: Enable pinctrl, i2c and mmc

[PATCH v2 0/2] ARM: sun8i: Enable pinctrl, i2c and mmc

[Chen-Yu Tsai]

Hi Maxime,

This is v2 of the remaining sun8i series. I've dropped the patches you
merged. The remaining patches have been rebased onto sunxi-next.

This series enables all the controllers on sun8i that we already have
drivers for, excluding SPI as the tablet I have does not use it and
I cannot test it. If there's a way to test it without external connections
or devices please let me know.

The commit logs pretty much explain themselves. Note that PLL6 is not
implemented yet. I've some patches for the clocks that I will send later.


Cheers
ChenYu


Changes since v1:

  - Removed clock-frequency from i2c controller nodes, as they match
    the default value.
  - Dropped patches that were merged in v1.
  - Rebased onto sunxi-next.

[PATCH v2 2/2] ARM: dts: sun8i: Enable i2c controllers on ippo-q8h-v5

[Chen-Yu Tsai]

i2c0 is connected to the gsl1680 capacitive touch panel controller.
i2c1 is connected to an mma7660 3-axis accelerometer.
i2c2 is connected to the front and back gc0309 camera sensors.
The camera sensors require additional regulators be enabled before
they are available.

All these peripherals are not supported by the kernel yet.
