[PATCH] scsi: ufs-mediatek: Modify the minimum RX/TX lane count to 2
From: Stanley Chu
Date: Wed Aug 19 2020 - 04:43:47 EST
From: Andy Teng <andy.teng@xxxxxxxxxxxx>
MediaTek UFS host starts to support 2 lanes, thus modify the
minimum lane count to 2.
This modification shall not impact old 1-lane host because
PA_CONNECTEDRXDATALANES and PA_CONNECTEDTXDATALANES will limit the
target lanes properly during power mode change. So we could relax
the limitation in ufs_dev_params.
