Subject: [PATCH V5 0/5] PM: domains: Add control for switching back and forth to HW control
Date: Fri, 15 Mar 2024 16:40:41 +0530 [thread overview]
Message-ID: <20240315111046.22136-1-quic_jkona@quicinc.com> (raw)
This series adds support for dev_pm_genpd_set_hwmode() and dev_pm_genpd_get_hwmode() APIs
and support in gdsc provider drivers to register respective callbacks and venus consumer
driver example using above API to switch the power domain(GDSC) to HW/SW modes dynamically
at runtime.
Changes in V5:
- Updated 1st patch as per V4 review comments to synchronize the initial HW mode state by
invoking ->get_hwmode_dev()callback in genpd_add_device()
- With above change, SW cached hwmode will contain correct value initially, and it will be
updated everytime mode is changed in set_hwmode, hence updated dev_pm_genpd_get_hwmode()
to just return SW cached hwmode in 1st patch
- Updated commit text for 1st, 3rd, 4th and 5th patches
- Updated 3rd and 5th patches as per review comments received on V4 series
- Added R-By tags received in older series to 1st and 2nd patches
