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.
