Even though the corresponding node is supposed to be a child of the Baikal-T1 System Controller, its reg property is left required for compatibility. Signed-off-by: Serge Semin Cc: Alexey Malahov Cc: Thomas Bogendoerfer Cc: Andy Shevchenko Cc: Mika Westerberg Cc: linux-mips@vger.kernel.org --- Changelog v2: - Make the reg property being optional if it's Baikal-T1 System I2C DT node. Changelog v3: - Get back the reg property being mandatory even if it's Baikal-T1 System I2C DT node. Rob says it has to be in the DT node if there is a dedicated registers range in the System Controller registers space. --- Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml | 2 ++ 1 file changed, 2 insertions(+) diff --git a/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml b/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml index dff3f267bdee..4f746bef2374 100644 --- a/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml +++ b/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml @@ -31,6 +31,8 @@ properties: items: - const: mscc,ocelot-i2c - const: snps,designware-i2c + - description: Baikal-T1 SoC System I2C controller + const: baikal,bt1-sys-i2c reg: minItems: 1 -- 2.26.2
