From 8452e9ef2b08c7bd492194554cdffc67d0b2a51b Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 1 Oct 2010 16:37:00 -0700 Subject: OMAP1: Amstrad Delta: add support for camera This patch adds configuration data and initialization code required for camera support to the Amstrad Delta board. Three devices are declared: SoC camera, OMAP1 camera interface and OV6650 sensor. Default 12MHz clock has been selected for driving the sensor. Pixel clock has been limited to get reasonable frame rates, not exceeding the board capabilities. Since both devices (interface and sensor) support both pixel clock polarities, decision on polarity selection has been left to drivers. Interface GPIO line has been found not functional, thus not configured.
