From 25c4d74ea6f07f2aaa3df537619680ba967043f5 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Mon, 1 Dec 2008 09:44:59 -0300 Subject: V4L/DVB (9787): soc-camera: let camera host drivers decide upon pixel format Pixel format requested by the user is not necessarily the same, as what a sensor driver provides. There are situations, when a camera host driver provides the required format, but requires a different format from the sensor. Further, the list of formats, supported by sensors is pretty static and can be pretty good described with a constant list of structures. Whereas decisions, made by camera host drivers to support requested formats can be quite complex, therefore it is better to let the host driver do the work.
