Subject: [PATCH V2 0/5] Tegra xHCI genpd support
Date: Fri, 28 Sep 2018 15:11:45 +0100 [thread overview]
Message-ID: <1538143910-24400-1-git-send-email-jonathanh@nvidia.com> (raw)
This series add genpd support for the Tegra xHCI device that requires
more than one power-domain to operate.
This series is making changes to more than one subsystem and at first
glance may look like a maintainers nightmare. However, my proposal is
this, once reviewed and people are happy ...
1. Patches 1-3 should be merged first. Patches 1 can go via the Tegra
tree and 2-3 via the USB tree.
2. Once patches 1-3 are accepted, then 4 and 5 can be merged via the
Tegra tree.
Changes since V1:
- Dropped unneeded patch to export symbol for genpd API
- Added patch to power-off XUSB domains
- Slight re-work to Tegra xHCI driver changes to simplify clean-up path.
