Subject: [PATCH 0/1] media: i2c: max96717: add test pattern ctrl

Hi,
Taking as reference the work done by Julien Massot on the MAX96716 driver
the test pattern generator on the serializer side MAX96717 has been implemented.
This work was done also to test and validate the GMSL2 version of the Alvium
camera on i.MX8MP ISI path.

HW setup:
 - alvium -> max96717 -> max96716 -> i.MX8MP (ISI path)

During the test it's mandatory to put also the de-serializer into pixel
mode disabling tunnel mode.
This can be done writing bit 0 of MIPI_TX52 (0x474) TUN_EN reg.

Test pattern output:

Thanks & Regards,
Tommaso
