Subject: [RFC PATCH v3 4/6] dt-bindings: clock: meson: document A1 SoC audio clock controller driver
Add device tree bindings for A1 SoC audio clock and reset controllers.
Signed-off-by: Jan Dakinevich <jan.dakinevich@...utedevices.com>
---
This controller has 6 mandatory and up to 20 optional clocks. To describe
this, I use 'additionalItems'. It produces correct processed-schema.json:
"clock-names": {
"maxItems": 26,
"items": [
{
"const": "pclk"
},
{
"const": "dds_in"
},
{
"const": "fclk_div2"
},
{
"const": "fclk_div3"
},
{
"const": "hifi_pll"
},
{
"const": "xtal"
}
],
"additionalItems": {
"oneOf": [
{
"pattern": "^slv_sclk[0-9]$"
},
{
"pattern": "^slv_lrclk[0-9]$"
}
]
},
"type": "array",
"minItems": 6
},
and it behaves as expected. However, the checking is followed by
complaints like this:
Documentation/devicetree/bindings/clock/amlogic,a1-audio-clkc.yaml: properties:clock-names:additionalItems: {'oneOf': [{'pattern': '^slv_sclk[0-9]$'}, {'pattern': '^slv_lrclk[0-9]$'}]} is not of type 'boolean'
And indeed, 'additionalItems' has boolean type in meta-schema. So, how to
do it right?
