This patch series introduces smartreflex and voltage driver support
for OMAP3430 and OMAP3630. SmartReflex modules do adaptive voltage
control for real-time voltage adjustments.
Originally all the functionalities introduced in this patch
were present in arch/arm/mach-omap2/smartreflex.c file in Kevin's
pm tree. This patch series does a major rewrite of this file
and introduces a separate voltage driver. Major contributors
to the original driver are
Eduardo Valentin (1):
OMAP3: PM: SmartReflex: Fix scheduled while atomic problem
Kalle Jokiniemi (1):
OMAP3: PM: SmartReflex driver integration
Kevin Hilman (2):
temp: SR: IO_ADDRESS conversion
OMAP: SR: OPP interfaces removed from OMAP PM layer
Nishanth Menon (1):
omap3: pm: sr: replace get_opp with freq_to_opp
Paul Walmsley (2):
OMAP SR: use opp_find_opp_by_opp_id()
OMAP SR: use OPP API for OPP ID, remove direct access
Phil Carmody (2):
OMAP3: PM: Don't do unnecessary searches in omap_sr_vdd*_autocomp_store
OMAP3: PM: Early exit on invalid parameters
Rajendra Nayak (9):
OMAP3: SR: Fix init voltage on OPP change
OMAP3: SR: Update VDD1/2 voltages at boot
OMAP3: SR: Use sysclk for SR CLKLENGTH calc
OMAP3: SR: Reset voltage level on SR disable
OMAP3: SR: Replace printk's with pr_* calls
OMAP3: SR: Remove redundant defines
OMAP3: SR: Fix SR driver to check for omap-pm return values
OMAP3: PM: Put optimal SMPS stabilization delay
OMAP3: SR: Wait for VP idle before a VP disable
Roger Quadros (4):
OMAP3: PM: Fix Smartreflex when used with PM_NOOP layer
OMAP3: PM: Make Smartreflex driver independent of SRF
OMAP3: PM: Do not Enable SmartReflex if OPP tables not defined
OMAP3: PM: Smartreflex: Fix VDD2 OPP determining logic
Romit Dasgupta (1):
omap: pm: SR: use enum for OPP types
Teerth Reddy (1):
OMAP3: SR: Replace SR_PASS/FAIL,SR_TRUE/FALSE
Tero Kristo (1):
Smartreflex: Avoid unnecessary spam
This patch series is based against origin/opp branch off
Kevin's pm tree which in turn is based off lo-master.
This series will apply against lo-master also but will
break compilation due to lack of opp framework support
on lo-master.
This patch series has been tested on OMAP3430 SDP,
OMAP3630 SDP and ZOOM3 with the following menuconfig
options enabled.
System type -> TI OMAP Implementations -> Smartreflex Support
System type -> TI OMAP Implementations ->
Class 3 mode of Smartreflex Implementation
Device Drivers -> Multifunction device drivers ->
Support power resources on TWL4030 family chips
Thara Gopinath (8):
OMAP3: PM: Adding voltage driver support for OMAP3
OMAP3: PM: Adding smartreflex driver support.
OMAP3: PM: Adding smartreflex device file.
OMAP3: PM: Adding smartreflex hwmod data
OMAP3: PM: Adding smartreflex class3 driver
OMAP3: PM: Adding T2 enabling of smartreflex support
OMAP: PM: Allowing an early init of pm debugfs driver.
OMAP3: PM: Adding debug support to Voltage and Smartreflex drivers
