Hardware team report below issue on smith: DSI0 have overshoot, undershoot issue and DSI1 data and clock line is too rounded. Hardware team advice to modify the DSI driver strength with Decreasing DSI0 driver strength to 0x66 Increasing DSI1 driver strength to 0xcc Change-Id: If39a3a5f2c4a1a6aaf53728cbd90325cd579a141 Signed-off-by: shuoyan <[email protected]> Reviewed-on: https://gerrit.mot.com/1706309 SME-Granted: SME Approvals Granted SLTApproved: Slta Waiver Tested-by: Jira Key Reviewed-by: Shanshan Dai <[email protected]> Reviewed-by: Ling Jin <[email protected]> Submit-Approved: Jira Key
