New Features
============
*) Add driver for USB PHYs on sun9i
*) Add driver for USB PHY on dm816x
*) Modified exynos5-usbdrd driver to add support for Exynos5433 SoC

Fixes
=====
*) Fix power_on/power_off failure paths in some drivers

*) Fix build errors due to missing export symbols in qcom-ufs driver
*) Make all the functions return proper error values

Cleanups
========

*) remove un-necessary ifdef CONFIG_OF

phy: miphy28lp: Convert to devm_kcalloc and fix wrong sizof

2015-03-13T11:44:37+00:00

Prefer devm_kcalloc over devm_kzalloc with multiply.
In additional, use sizeof(phy) is incorrect, fix it.

phy: miphy28lp: Avoid calling of_get_child_count() multiple times

2015-03-04T13:01:47+00:00

Currently, of_get_child_count() is called in each iteration of the for loop in
miphy28lp_xlate(). This patch stores the return value of of_get_child_count()
in miphy_dev->nphys and call of_get_child_count() once in miphy28lp_probe().

phy: miphy28lp: Pass sysconfig register offsets via syscfg dt property.

2015-01-21T09:53:06+00:00

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy28lp phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces like
it does currently for miphy28lp. This change then also aligns us to how other
platforms such as keystone and bcm7445 pass there syscon offsets via DT.

I have updated the miphy28lp phy driver same way as Peter's implementation.

phy: miphy28lp: Add SSC support for PCIE

2014-11-12T13:10:12+00:00

SSC is the technique of modulating the operating frequency of a signal
slightly to spread its radiated emissions over a range of frequencies.
This reduction in the maximum emission for a given frequency helps meet
radiated emission requirements.
These settings are applicable for PCIE with Internal clock.
