Subject: [PATCH] media: i2c: imx290: Factor out black level setting to
|
|
a function
|
|
|
|
Upstream commit ee4ce8936693
|
|
|
|
The black level programmed in the BLKLEVEL register depends on the
|
|
output format. The black level value computation is currently performed
|
|
in imx290_set_ctrl(), in addition to having different black level values
|
|
in the output-specific register value tables. Move it to a separate
|
|
function to simplify the imx290_set_ctrl() code.
