Subject: [PATCH] media: i2c: imx290: Support 60fps in 2 lane operation
|
|
|
|
Should be upstream commit 7d4f22ba99cc
|
|
|
|
Commit "97589ad61c73 media: i2c: imx290: Add support for 2 data lanes"
|
|
added support for running in two lane mode (instead of 4), but
|
|
without changing the link frequency that resulted in a max of 30fps.
|
|
|
|
Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency
|
|
and pixel rate" then doubled the link frequency when in 2 lane mode,
|
|
but didn't undo the correction for running at only 30fps, just extending
|
|
horizontal blanking instead.
|
|
|
|
Remove the 30fps limit on 2 lane by correcting the register config
|
|
in accordance with the datasheet for 60fps operation over 2 lanes.
