[edit] Introduction

This wikipage describes the proposed PM SW upstreaming plan for 2011.

NOTE: The readiness and acceptance of a feature is decided by the community and hence may deviate from proposed target merge widnows mentioned below. The plan may undergo further changes in future based on upstreaming progress made till that time.

OMAP PM SW Upstreaming Plan

Feature	Owner	3.1	3.2	3.3	Dependency/ Remarks
PM Frameworks (Power /Clock Domain), HWMOD Framework & runtime PM	Rajendra	Clock Sequencing patches merged	Following features to be pushed. (1)Support context loss count (2) Support for SAR (3) Support for IO Daisychain	Enhancements / suggestions from 3.2 reviews	NA
OMAP4 MPU Low Power state (CSWR, OSWR & OFF) in cpuidle and suspend	Santosh	None	OMAP4 MPU Low powerstate (MPU CSWR, OSWR & OFF)	Enhancements / suggestions from 3.2 reviews	NA
PRCM Chain Handler	Tero	None	PRCM Chain Handler support for OMAP3 & OMAP4	Enhancements / suggestions from 3.2 reviews	Patch series V6 posted and under review. Need review from Paul.
OMAP4 Core Low Power state	Rajendra	None	Support for Core CSWR in suspend/cpuidle path	Support for Core OSWR and OFF in suspend/cpuidle path	Depends on 1. Acceptance of MPU Low power state feature 2. Acceptance of PRCM Chain handler 3. UART Runtime PM adaptation acceptance
Voltage Layer clean up	Tero	None	1. Converting OMAP SMPS into Ragulators 2. Voltage Parameter Segregation 3. Rest of voltage layer clean up	Enhancements / suggestions from 3.2 reviews	Dependency: 1. Inputs from Kevin on list of pending activities form voltage domain clean up 2. Review of Regulator and parameter seggregation patches. Current status: (1) OMAP SMPS patch V4 posted and under review. (2) Voltage segregation patch v2 posted and under review
OMAP4460 TPS changes	Tero	NA	NA	OMAP4460 TPS & Voltage scaling support	Depends on acceptance of voltage layer clean up
DVFS Framework	Mike	NA	NA	OMAP3 &OMAP4 DVFS Framework	NA
SR 1.5	Nishant Menon	NA	NA	SR 1.5 framework	Patches to Convert SR into hwmon driver by Paul
ABB	Mike	None	ABB Support for OMAP3 & OMAP4	Enhancements / suggestions from 3.2 reviews	Patch V2 posted and under review. Need to be reviewed by Kevin
Constraint Framework	Jean	None	OMAP3 & OMAP4 device latency constraints	Throughput latency constraints	Patch V4 posted. Raffael is OK with QOS Patches and wants to queue for 3.2. OMAP specific patches need ack from Paul & Kevin
HW Traceframework	Jean	NA	NA	OMAP4 HW Trace Framework	NA
cpuhotplug governor framework	Mike	NA	OMAP4 cpuhotplug governor framework	Enhancements / suggestions from 3.2 reviews	Being reviewed by Linaro
OMAP4460 thermal driver	Keerthy	NA	OMAP4460 thermal sensor driver	Enhancements / suggestions from 3.2 reviews	Since this feature needs to be added only for OMAP4460, we need to have a mechanism to add OMAP4460 specific hwmod data.
Thermal Framework	Linaro	NA	NA	TBD	This activity is driven as part of Linaro Blueprint. Need to see how it progresses
PM Consolidation	Jean	None	None	PM Consolidation task. 1. Clean up PM Initialization sequence 2. Convert PM into a loadable library	NA
