charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-phy" Errors-To: linux-phy-bounces+linux-phy=archiver.kernel.org@lists.infradead.org From: Paul Kocialkowski 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.
