| |
Section 13.7.6.13 "CSI Image Parameter Register" of the i.MX 8M Quad Applications Processors Reference Manual states that the line size should be divisible by 8 bytes. However, the hardware also accepts sizes divisible by 4 bytes.
This patch accepts line sizes divisible 4-bytes in non-planar mode.

Hello,
my previous patch identified something that was not a problem, so I'm sending a different one.
This has been tested on the Librem 5.
Cheers, Dorota
