"Fix the height discrepency by correcting the Y_OUT_SIZE,
HTRIMMING_START, and changing the WINMODE, followed by the corresponding
updates to reflect the new minimum vblanking periods."
I'm curious though - why does IMX335_REG_HTRIMMING_START jump /so/ much
here? Something to do with the WINMODE change?
Because I've seen this works and with the optional update to the commit
