The DSI1_PHY_AFEC0_PD_DLANE1 and DSI1_PHY_AFEC0_PD_DLANE3 register definitions were swapped, so trying to use more than a single data lane failed as lane 1 would get powered down. (In theory a 4 lane device would work as all lanes would remain powered).
Correct the definitions.

Wouldn't this deserve a "Fixes: ..." and "Cc: stable@vger.kernel.org" tag, as this bug is present in all stable releases since this driver was introduced? I think it would be really helpful to have it backported.
Agree, this would be nice:
Fixes: 4078f5757144 ("drm/vc4: Add DSI driver")
With that,
