[PATCH 0/9] ARM: rockchip: add power-domains for Cortex-A9 socs

[PATCH 0/9] ARM: rockchip: add power-domains for Cortex-A9 socs

[Heiko Stuebner]

A small bit of cleanup for some clocks nobody used yet but that
need to be toggled for the synchronous reset done on power-domain
state changes.

Domain values are done by the book (aka soc documentation for pmu
and power-domain <-> ip block connections) and tested with the gpu
and the wip lima kernel driver on rk3188.

Heiko Stuebner (9):
  clk: rockchip: add more rk3188 graphics clock ids
  clk: rockchip: use new cif/vdpu clock ids on rk3188
  dt-bindings: add power-domain header for RK3188 SoCs
  dt-bindings: add power-domain header for RK3066 SoCs
  dt-bindings: add compatibles for rk3066/rk3188 power controllers
  soc: rockchip: power-domain: add rk3188 powerdomains
  soc: rockchip: power-domain: add rk3066 powerdomains
  ARM: dts: rockchip: add qos nodes found on rk3066 and rk3188
  ARM: dts: rockchip: add rk3066/rk3188 power-domains

[PATCH 1/9] clk: rockchip: add more rk3188 graphics clock ids

[Heiko Stuebner]

Add ids for cif, v{d/e}pu clocks on rk3188. ACLK_CIF does get a needed
1 at it's end but that should be safe because no driver for the camera
interface has surfaced so far and the old vendor kernels for these socs
are based on linux-3.0 and still used board files then, so there really
are no previous users anywhere to be found.

[PATCH 8/9] ARM: dts: rockchip: add qos nodes found on rk3066 and rk3188

[Heiko Stuebner]

QoS nodes keep information about priorites etc on the interconnect
and loose state when the power-domain gets disabled. Therefore the
power-domain driver stores the settings of available qos nodes and
restores them when the power-domain gets enabled again.

So add the qos nodes found on the Cortex-A9 socs from Rockchip, so
that they can then be connected to the power-domains.
