Subject: [PATCH] gspca-stk1135: Add delay after configuring clock
Date: Sun, 3 Nov 2013 01:09:07 +0100 [thread overview]
Message-ID: <1383437347-29262-1-git-send-email-linux@rainbow-software.org> (raw)
Add a small delay at the end of configure_clock() to allow sensor to initialize.
This is needed by Asus VX2S laptop webcam to detect sensor type properly (the already-supported MT9M112).
