Subject: [PATCH] media: i2c: imx290: Simplify imx290_set_data_lanes()
|
|
|
|
Upstream commit 76c001287f6a
|
|
|
|
There's no need to check for an incorrect number of data lanes in
|
|
imx290_set_data_lanes() as the value is validated at probe() time. Drop
|
|
the check.
|
|
|
|
The PHY_LANE_NUM and CSI_LANE_MODE registers are programmed with a value
|
|
equal to the number of lanes minus one. Compute it instead of handling
|
|
it in the switch/case.
