Subject: [PATCH v4 0/3] drivers: soc: xilinx: Add support for ZynqMP power domain driver
Date: Fri, 1 Feb 2019 14:08:47 -0800 [thread overview]
Message-ID: <1549058930-18644-1-git-send-email-jollys@xilinx.com> (raw)
The zynqmp power domain driver communicates the usage requirements
for logical power domains / devices to the platform FW.
FW is responsible for choosing appropriate power states,
taking Linux' usage information into account.
v4:
- Added reviewed tag for dt bindings
- Remove local device list for each domain and use list maintained in core genpd structure
- Remove hardcoded pd-id to node ID mapping. Instead use argument passed in peripheral node as node ID.
Firmware would validate node ID when APIs requested from genpd ops.
v3:
- Changed binding to have FW node as a power controller as suggested by Rob
- Updated FW driver to register it as mfd child devices from firmware probe
- Move bindings location as suggested
v2:
- Rebased on top of latest firmware driver patch series
- Updated driver name from zynqmp-genpd to zynqmp-power-controller
- Updated device tree bindings to move power controller node under firmware node
