[PATCH v2 0/6] media: adv748x: Implement dynamic routing support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
   second iteration for adv748x dynamic selection of video source.

Please refer to v1 cover letter for more details:
https://patchwork.kernel.org/cover/10723971/

This v2 addresses comments received from Kieran and Laurent, with the most
notable changes in patches 3/6 and 6/6.

Tested on R-Car E3 Ebisu board, where both AFE and HDMI backends share a
single CSI-2 output.

A noted on v1 cover letter, for the series to work on other R-Car SoC the
number of CSI-2 data lanes has to be negotiated, as the AFE->TXA link works
only when up to 2 data lanes are used, while most of Gen 3 SoCs (E3 excluded)
are configured to use 4 data lanes.


The series is based on media tree master with the following series from
Niklas applied on top:
