Subject: [DPU PATCH v3 0/2] Remove DPU RSC support
Date: Wed, 11 Apr 2018 20:18:45 +0530 [thread overview]
Message-ID: <1523458127-14304-1-git-send-email-ryadav@codeaurora.org> (raw)
MSM display controller hardware (DPU) has an inbuilt RSC
(Resource Coordinator) HW block which can control power
resources and bus bandwidth voting based on frame timing
parameters without DPU driver intervention.
Downstream driver relies on RSC driver for controlling these
resources (via RSC HW block) for better power benefits.
Removing RSC device/driver support till the RSC dependencies
make their way upstream.
In absence of RSC HW, DPU driver controls these resources
currently via a custom implementation for power management.
Next, we will work on moving the power resource management
using runtime_pm.
Corresponding devicetree binding are also removed.
Details for DPU driver upstreaming:

Changes in v3:
- Added more details to commit message and cover letter (Daniel Vetter)
Changes in v2:
- Remove last reference to dpu_power_rsc_update
- Add DPU PATCH tag for better filtering
- Rebase on tip of for-next-staging
