Subject: [PATCH v3 0/5] media: imx335: Support additional link-freq and TPG

This series adds support for additional link frequency and
test pattern generator on IMX335.

Patch 1/5 is a drive-by patch which sets default value to one
of the reserved register. The non-default value of 0x01 has been
found responsible to break CSI-2 configuration on one of the i.MX8MP
based platform. Setting to default value seem to fix it and has been
tested on RPi5 (downstream BSP) in additional to i.MX8MP platform
running mainline.

Patch 2/5 adds usage of v4l2_link_freq_to_bitmap V4L2 helper.

Patch 3/5 supports for additional link-frequency supported by IMX335

Patch 4/5 is also a prep-up patch for TPG introduction(in 5/5), as the test
pattern needs sensor to be powered up to apply the test pattern.

Patch 5/5 adds the TPG.

changes in v3:
- Update the patch 1/5 to set the reserved register value
  to it's default value (instead of dropping it).
- Drop "i2c: " from commit message in 3/5

Changes in v2:
- add new patch 2/5 to use v4l2_link_freq_to_bitmap
- fixup a return; in 4/5
