Subject: [PATCH 45/82] net: sparx5: change spx5_wr to spx5_rmw in cal update()
|
|
|
|
In preparation for lan969x, use spx5_rmw() for enabling the update of
|
|
the calendar. This is required to not overwrite the DSM_TAXI_CAL_CFG
|
|
register, as an additional write will be added before this one, in a
|
|
subsequent patch.
