Subject: [PATCH 1/2] New driver for MI2020 sensor with GL860 bridge
Date: Sun, 28 Feb 2010 21:19:25 +0100	[thread overview]
Message-ID: <1267388365.1854.30.camel@miniol> (raw)

gspca - gl860: updates to prepare the new driver for MI2020 sensor

From: Olivier Lorin <o.lorin@laposte.net>

- General changes for all drivers because of new MI2020 sensor driver :
  - add the light source control
  - control value changes only applied after an end of image
  - replace msleep with duration less than 5 ms by a busy loop
- Fix for an irrelevant OV9655 image resolution identifier name

Priority: normal

Signed-off-by: Olivier Lorin <o.lorin@laposte.net>
