Subject: [PATCH v6 0/3] ARM: rk3288 : Add PM Domain support
From: "jinkun.hong" <jinkun.hong@...k-chips.com>
Add power domain drivers based on generic power domain for Rockchip platform,
and support RK3288.
https://chromium-review.googlesource.com/#/c/220253/9
This is the GPU driver, add the following information in DT,
and it can support the PMDOMAIN.
gpu: gpu@...30000 {
compatible = "arm,malit764",
"arm,malit76x",
"arm,malit7xx",
"arm,mali-midgard";
reg = <0xffa30000 0x10000>;

<GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>;

clocks = <&cru ACLK_GPU>;
clock-names = "aclk_gpu";

Based on:
- [PATCH v1 1/4] PM / clock_ops: Add pm_clk_add_clk()
http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg735599.html
Changes in v6:
- delete pmu_lock
- modify dev_lock using mutex
- pm_clk_resume(pd->dev) change to pm_clk_resume(ed->dev)
- pm_clk_suspend(pd->dev) change to pm_clk_suspend(ed->dev)
- add devm_kfree(pd->dev, de) in rockchip_pm_domain_detach_dev
Changes in v5:
- delete idle_lock
- add timeout in rockchip_pmu_set_idle_request()
Changes in v4:
- use list storage dev
Changes in v3:
- change use pm_clk_resume() and pm_clk_suspend()
- DT structure has changed
- Decomposition power-controller, changed to multiple controller
(gpu-power-controller, hevc-power-controller)
Changes in v2:
- remove the "pd->pd.of_node = np"
- move clocks to "optional"
- make pd_vio clocks all one entry per line and alphabetize.
- power: power-controller move back to pinctrl: pinctrl.
