Subject: [PATCH v2 02/19] phy: Distinguish between Rx and Tx for MIPI D-PHY with submodes
Date: Sat, 28 Nov 2020 15:28:22 +0100 [thread overview]
Message-ID: <20201128142839.517949-3-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20201128142839.517949-1-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.
