Subject: [PATCH v4 0/4] i2c: adv748x: add support for CSI-2 TXA to work in 1-, 2- and 4-lane mode
Date: Thu, 29 Nov 2018 03:01:43 +0100	[thread overview]
Message-ID: <20181129020147.22115-1-niklas.soderlund+renesas@ragnatech.se> (raw)

Hi,

This series allows the TXA CSI-2 transmitter of the adv748x to function
in 1-, 2- and 4- lane mode. Currently the driver fixes the hardware in
4-lane mode. The driver looks at the standard DT property 'data-lanes'
to determine which mode it should operate in.

Patch 1/4 lists the 'data-lanes' DT property as mandatory for endpoints
describing the CSI-2 transmitters. Patch 2/4 refactors the
initialization sequence of the adv748x to be able to reuse more code.
Patch 3/4 adds the DT parsing and storing of the number of lanes. Patch
4/4 merges the TXA and TXB power up/down procedure while also taking the
configurable number of lanes into account.

The series is based on the latest media-tree master and is tested on
Renesas M3-N in 1-, 2- and 4- lane mode.
