[PATCH v2 13/21] staging: media: tegra-video: move default format to soc-specific data

Luca Ceresoli
2022-11-28T15:27:31Z

The tegra_default_format in vi.c is specific to Tegra210 CSI.

In preparation for adding Tegra20 VIP support, move the default format to a
new field in the soc-specific `struct tegra_vi_soc`. Instead of an entire
format struct, only store a pointer to an item in the existing format
array.

No functional changes. The format pointed to is the same that used to be in
vi.c.
