SD Card v3.01 in the market is not compatible with BYT SDHC IP
in SoC because this IP only support SD v3.0 only. So, we are
forcing DDR50 mode to always step down to SDR25.

A host controller for a SD card may need a GPIO
for card detect in order to wake up from runtime
suspend when a card is inserted.  If that GPIO is
not configured, then the host controller will not
wake up.  Fix that for the affected devices by not
enabling runtime PM unless the GPIO is successfully
set up.

This improves the accuracy of base_unit calculation
so that the resulting PWM frequency will be more optimal.

The change in the patch is meant for Intel BayTrail only

Right now the CONFIG_INPUT_* options are scattered at various
places in config fragments. The plan is to get them in one place
for cleanliness.

To begin with a new feature is created with name input.scc.
And it is populated with the needed CONFIG_INPUT_EVDEV .

Signed-off-by: Nitin A Kamble <nitin.a.kamble@intel.com>

Include the input.scc to get the CONFIG_INPUT_EVDEV enabled.

The evdev kernel driver is needed to create /dev/input/event* devices.
These devices are used by Xserver to connect to keyboard & mouse kind
of input devices. Without this change some of the BSPs need
  AutoAddDevices = false
in their xorg.conf, which is considered as an undesired hack around
the issue.
