Re: [PATCH v7 3/3] media: i2c: hm1092: Add ACPI enumeration and the 19.2 MHz configuration

[Ray Strode <halfline@gmail.com>]

Hi,

Regarding the crop-bounds question: the 19.2 MHz mode reports a 1294x734
crop at (0,0), which extends outside the advertised 1280x720 bounds at
(8,8).

Reporting the native array as CROP_BOUNDS accommodates that readout window
while keeping CROP_DEFAULT as the active area:

This changes only the reported bounds; the mode's crop and register
configuration stay the same.
