Re: [PATCH 1/8] media: ov8858: support 19.2 MHz clock and CHT gain setup

[Maurizio Casciano]

Thank you. v2 splits the existing 24 MHz digital-gain packing into a
preparatory patch before adding the clock-specific path.

I retained the two masks and shift for that existing path because the 14-bit
control value is not laid out contiguously in the 16-bit register write:
0x350a receives gain[13:6], while 0x350b[5:0] receives gain[5:0]. A single
combined mask would not perform that repacking.

The remaining review points are addressed in v2, including HZ_PER_MHZ,
single-line writes, a table-selected gain range, and declaration/layout
cleanup. Pahole on the final built object reports struct ov8858 at 792 bytes,
with xvclk_rate naturally aligned at offset 8 and no hole introduced by it.
