From: Quentin Schulz <redacted> [ Upstream commit 36c53cf0f46526b898390659b125155939f67892 ] In the DT binding, it is specified nowhere that 'vsc8531,edge-slowdown' is an u8, even though it's read as an u8 in the driver. Let's update the driver to take into consideration that the 'vsc8531,edge-slowdown' property is of the default type u32. Signed-off-by: Quentin Schulz <redacted> Signed-off-by: David S.
