From a924a499adb89f52046936deac87264774652a81 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 12 Nov 2008 08:41:29 -0300 Subject: V4L/DVB (9607): em28xx: Properly implement poll support for IR's The first em28xx were based on i2c IR's. However, some newer designs are coming with a polling-based IR. Those are done by reading a register set at em28xx. This patch adds core polling support for those devices. Later patches will add support for some device-specific IR's. This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and shares the common getkey masks defined at ir-common.
