Subject: [PATCH v2 1/7] dt-bindings: phy: samsung,usb3-drd-phy: add gs101 compatible
Date: Wed, 01 May 2024 10:19:36 +0100	[thread overview]
Message-ID: <20240501-usb-phy-gs101-v2-1-ed9f14a1bd6d@linaro.org> (raw)
In-Reply-To: <20240501-usb-phy-gs101-v2-0-ed9f14a1bd6d@linaro.org>

Add a dedicated google,gs101-usb31drd-phy compatible for Google Tensor
gs101 SoC.

It needs additional clocks enabled for register access, and additional
memory regions (PCS & PMA) are required for successful configuration.

Signed-off-by: André Draszik <andre.draszik@linaro.org>

v2: avoid having nested else/if, and instead change the existing 'else'
    to explicitly state the platforms using 'if'
