Subject: [PATCH v2 02/11] [media] stv0367: Add support for 16Mhz reference clock
Date: Thu, 30 Jul 2015 18:08:52 +0100 [thread overview]
Message-ID: <1438276141-16902-3-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1438276141-16902-1-git-send-email-peter.griffin@linaro.org>
The B2100A dvb NIM card from ST has 2x stv0367 demodulators
and 2x TDA18212 silicon tuners, with a 16Mhz crystal. To
get this working properly with the upstream driver we need
to add support for the 16Mhz reference clock.
