[PATCH 0/4] Introduce drivers/soc and add QCOM GSBI driver

[Andy Gross]

The first patch in this set adds the drivers/soc directory and all the necessary
plumbing.  These changes were discussed at the kernel summit and also were
introduced in an earlier patch set from Santosh Shilimkar.

Reference the following set of patches:
https://lkml.org/lkml/2014/2/28/567

The remaining patches add the QCOM GSBI (General Serial Bus Interface) driver,
device tree binding information for both the GSBI and child node interaction,
and lastly a patch to fix the current MSM serial driver to work correctly with
the GSBI changes.

Before this patch series, serial drivers (UART, I2C, and SPI) were all directly
accessing the overarching mux control settings for the parent GSBI device.  This
leads to unfortunate interactions when you want a UART and I2C device which
share the same GSBI interface.  By moving the serial devices to child nodes of
the GSBI, we can get the right mode setting for the ports and keep the children
from accessing the GSBI directly.
