This block is split into two parts, the BSC and the AUTO_I2C, -lying in two separate register areas. - -The AUTO_I2C block has a mailbox-like interface and will take away the -BSC control from the CPU if enabled. However, the BSC is the actually -the same controller than the one supported by the brcmstb driver, and -the AUTO_I2C doesn't really bring any immediate benefit. - -We can model it in the DT as a single device with two register range, -which will allow us to use or or the other in the driver without -changing anything in the DT. - -Cc: Kamal Dasu <kdasu.kdev@gmail.com> -Cc: Wolfram Sang <wsa@the-dreams.de> -Cc: bcm-kernel-feedback-list@broadcom.com -Cc: linux-i2c@vger.kernel.org -Cc: devicetree@vger.kernel.org -Acked-by: Florian Fainelli <f.fainelli@gmail.com> -Reviewed-by: Rob Herring <robh+dt@kernel.org> -Signed-off-by: Maxime Ripard <maxime@cerno.tech> ---- - .../bindings/i2c/brcm,brcmstb-i2c.yaml | 40 ++++++++++++++++++- - 1 file changed, 39 insertions(+), 1 deletion(-) - ---- a/Documentation/devicetree/bindings/i2c/brcm,brcmstb-i2c.yaml -+++ b/Documentation/devicetree/bindings/i2c/brcm,brcmstb-i2c.yaml -@@ -15,11 +15,21 @@ allOf: - properties: - compatible: - enum: -+ - brcm,bcm2711-hdmi-i2c - - brcm,brcmstb-i2c - - brcm,brcmper-i2c - - reg: -- maxItems: 1 -+ minItems: 1 -+ maxItems: 2 -+ items: -+ - description: BSC register range -+ - description: Auto-I2C register range -+ -+ reg-names: -+ items: -+ - const: bsc -+ - const: auto-i2c - - interrupts: - maxItems: 1 -@@ -45,6 +55,26 @@ required: - - unevaluatedProperties: false - -+if: -+ properties: -+ compatible: -+ contains: -+ enum: -+ - brcm,bcm2711-hdmi-i2c -+ -+then: -+ properties: -+ reg: -+ minItems: 2 -+ -+ required: -+ - reg-names -+ -+else: -+ properties: -+ reg: -+ maxItems: 1 -+ - examples: - - | - bsca: i2c@f0406200 { -@@ -56,4 +86,12 @@ examples: - interrupt-names = "upg_bsca"; - }; - -+ - | -+ ddc0: i2c@7ef04500 { -+ compatible = "brcm,bcm2711-hdmi-i2c"; -+ reg = <0x7ef04500 0x100>, <0x7ef00b00 0x300>; -+ reg-names = "bsc", "auto-i2c"; -+ clock-frequency = <390000>; -+ }; -+ - ... |
