From: "jinkun.hong" <jinkun.hong at rock-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 at ffa30000 {
compatible = "arm,malit764",
"arm,malit76x",
"arm,malit7xx",
"arm,mali-midgard";
reg = <0xffa30000 0x10000>;
interrupts = <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "JOB", "MMU", "GPU";
clocks = <&cru ACLK_GPU>;
clock-names = "aclk_gpu";
operating-points = <
/* KHz uV */
100000 800000
200000 850000
300000 950000
400000 1000000
600000 1150000

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 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.
