The main motivations behind this patch series are the following
1. Making smartreflex a platform driver with omap-device layer.
2. Separating voltage specific code from smartreflex.c and other
locations and consolidating them into voltage.c and voltage.h.
3. Smartreflex module can have Class 1 Class 2 or Class 3 implementations
depending on the PMIC in use. Making smartreflex.c capable
of handling both the Class 2 and 3 implementaions and separating out
class specific code into a separate class driver.
4. Remove dependencies on opp id in the smartreflex and
voltage drivers
5. Implementating latest TI recommended register settings for
Smartreflex and Voltage processor module as well as recommended
sequences for enabling and disabling of Smartreflex and Voltage
processor modules.
6. Implementing VP force update method of voltage scaling which is
again TI hardware recommended.
What this patch series does not address are
1. Separating PMIC specific portions from smartreflex and voltage code.
2. OMAP3630 and OMP4 smartreflex support.
This patch series is based on Kevin's PM tree origin/pm-wip-opp branch
and is dependent on the following patches not yet applied onto this branch.
http://patchwork.kernel.org/patch/81504/
http://patchwork.kernel.org/patch/81606/
This patch series has been tested on OMAP3430 SDP with basic power
management tests including the dvfs scripts.
