From d24b69fc6b0aca41a205b2b5abaf3f243ad7d48b Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 28 Jul 2014 14:25:28 -0300 Subject: [PATCH] [media] rc-main: allow raw protocol drivers to restrict the allowed protos On some hardware (au0828/au8522), the hardware is broken with regards to the initial pulse detection. So, the driver needs to produce a fake start pulse. That limits the acceptable protocols, as it is not possible to produce a fake pulse that would cover all supported protocols. So, allow the driver to explicitly set the allowed protocols. If the driver doesn't specify, keep the old behavior.
