Subject: [PATCH 10/17] cx23885: For CX23888 IR, configure the IO pin mux IR pins explcitly
Date: Mon, 19 Jul 2010 21:19:40 -0400 [thread overview]
Message-ID: <1279588780.31145.5.camel@localhost> (raw)
In-Reply-To: <cover.1279586511.git.awalls@md.metrocast.net>
Explicitly configure the IR Tx and IR Rx pins to be driven by the
IR Rx and Tx pads from the AV core for CX23888 IR.
For the HVR-1850 and HVR-1290 configure the IR Tx level inversion,
so the Tx LED is off when idle.
