From 859cac86f6c33c51b4e9e2c17bba3ad6b2d6b016 Mon Sep 17 00:00:00 2001 From: Hartmut Hackmann Date: Mon, 30 Oct 2006 23:56:59 +0100 Subject: added autodetected flag to the saa7134_dev structure From: Hartmut Hackmann In case the exact board type needs to be determined by probing or evaluating the eeprom, this flag allows to still set the board type via the card=xx insmod option. This is an extract of a patch by Francis Barber.

Maybe they may compile with kernels lower than 2.6.19, but upper than 2.6.16. Anyway,since the targeted OLPC hardware is not available yet, IMO, it doesn't make much sense to work on backporting the drivers to kernels lower than kernel 2.6.19.

Also, now, a driver may return a subset of the video array at the return, to be stored as the current_norm. For example, a driver may ask for V4L2_STD_PAL. At return, driver may change it to V4L2_STD_PAL_B. This way, a futher call to G_STD will return the exact detected video std.
