[linux-yocto] [PATCH 00/28][3.10] Baytrail LPSS I/O feature backport

[rebecca.swee.fun.chang at intel.com]

From: Chang Rebecca Swee Fun <rebecca.swee.fun.chang at intel.com>

Hi all,

Here is a series of patches that I've cherry-picked from mainline kernel into
linux-yocto-3.10. These patches are Baytrail PCI mode LPSS I/O features.
The patches consists of PWM, DMA, UART, USB device mode, I2C, and SPI device
drivers.

These patches was in valleyisland-io-1.0 currently. I will then rebase the
valleyisland-io feature branch to reduce the maintenance effort in feature
branch.

To help you in review process, one of the patch is actually pending to
mainline and it is now queuing in linux-next git repo.
The patch that I mentioned is:
e4f08d7 spi/pxa2xx-pci: Add common clock framework support in PCI glue layer
while the other patches are confirmed picked from mainline.

This series of patches had been built and tested on Bakersports, and
MinnowBoard MAX.

Please review the series of patches and merge them into linux-yocto-3.10
standard/base branch for feature enabling purposes.

Thanks in advance

Rebecca
