dt-bindings: power: convert rockchip-io-domain.txt to YAML
Current dts files with 'io-domains' nodes are manually verified.
In order to automate this process rockchip-io-domain.txt has to be
converted to YAML.
Changed:
Add supply properties for:
rockchip,rk3328-io-voltage-domain
rockchip,rv1108-io-voltage-domain
rockchip,rv1108-pmu-io-voltage-domain

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,rk3288-io-voltage-domain" for rk3288
|
||||

|
||||
- "rockchip,rk3368-io-voltage-domain" for rk3368
|
||||

- "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.
