Subject: [PATCH v2 1/3] dt-bindings: soc: rockchip: convert io-domain.txt to YAML
This patch moves the rockchip-io-domain.txt from power/avs dir to soc
dir and rename to io-domain.txt, without any change in the step.
Then covert the io-domain.txt to YAML.

-Rockchip SRAM for IO Voltage Domains:
--------------------------------------
-
-IO domain voltages on some Rockchip SoCs are variable but need to be
-kept in sync between the regulators and the SoC using a special
-register.
-
-A specific example using rk3288:
-- If the regulator hooked up to a pin like SDMMC0_VDD is 3.3V then
- bit 7 of GRF_IO_VSEL needs to be 0. If the regulator hooked up to
- that same pin is 1.8V then bit 7 of GRF_IO_VSEL needs to be 1.
-
-Said another way, this driver simply handles keeping bits in the SoC's
-general register file (GRF) in sync with the actual value of a voltage
-hooked up to the pins.
-
-Note that this driver specifically doesn't include:
-- any logic for deciding what voltage we should set regulators to
-- any logic for deciding whether regulators (or internal SoC blocks)
- should have power or not have power
-
-If there were some other software that had the smarts of making
-decisions about regulators, it would work in conjunction with this
-driver. When that other software adjusted a regulator's voltage then
-this driver would handle telling the SoC about it. A good example is
-vqmmc for SD. In that case the dw_mmc driver simply is told about a
-regulator. It changes the regulator between 3.3V and 1.8V at the
-right time. This driver notices the change and makes sure that the
-SoC is on the same page.
-
-
-Required properties:
-- compatible: should be one of:
- - "rockchip,px30-io-voltage-domain" for px30
- - "rockchip,px30-pmu-io-voltage-domain" for px30 pmu-domains
- - "rockchip,rk3188-io-voltage-domain" for rk3188
- - "rockchip,rk3228-io-voltage-domain" for rk3228
- - "rockchip,rk3288-io-voltage-domain" for rk3288
- - "rockchip,rk3328-io-voltage-domain" for rk3328
- - "rockchip,rk3368-io-voltage-domain" for rk3368
- - "rockchip,rk3368-pmu-io-voltage-domain" for rk3368 pmu-domains
- - "rockchip,rk3399-io-voltage-domain" for rk3399
- - "rockchip,rk3399-pmu-io-voltage-domain" for rk3399 pmu-domains
- - "rockchip,rv1108-io-voltage-domain" for rv1108
- - "rockchip,rv1108-pmu-io-voltage-domain" for rv1108 pmu-domains
-
-Deprecated properties:
-- rockchip,grf: phandle to the syscon managing the "general register files"
- Systems should move the io-domains to a sub-node of the grf simple-mfd.
-
-You specify supplies using the standard regulator bindings by including
-a phandle the relevant regulator. All specified supplies must be able
-to report their voltage. The IO Voltage Domain for any non-specified
-supplies will be not be touched.
