Subject: [PATCH v2 01/18] phy: Distinguish between Rx and Tx for MIPI D-PHY with submodes
Date: Wed, 26 May 2021 20:52:51 +0530 [thread overview]
Message-ID: <20210526152308.16525-2-p.yadav@ti.com> (raw)
In-Reply-To: <20210526152308.16525-1-p.yadav@ti.com>
From: Paul Kocialkowski <paul.kocialkowski@bootlin.com>
As some D-PHY controllers support both Rx and Tx mode, we need a way for
users to explicitly request one or the other. For instance, Rx mode can
be used along with MIPI CSI-2 while Tx mode can be used with MIPI DSI.
Introduce new MIPI D-PHY PHY submodes to use with PHY_MODE_MIPI_DPHY.
The default (zero value) is kept to Tx so only the rkisp1 driver, which
uses D-PHY in Rx mode, needs to be adapted.
