From 03388ae30260475650bab24223151397afb72ec9 Mon Sep 17 00:00:00 2001 From: Oliver Endriss Date: Fri, 9 Sep 2005 13:03:12 -0700 Subject: [PATCH] dvb: ttpci: av7110: RC5+ remote control support Improved remote control support for av7110-based cards: o extended rc5 protocol, firmware >= 0x2620 required o key-up timer slightly adjusted o completely moved remote control code to av7110_ir.c o support for multiple ir receivers o for now, all av7110 cards share the same ir configuration and event device Signed-off-by: Oliver Endriss Signed-off-by: Johannes Stezenbach Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/media/dvb/ttpci/av7110.c | 70 ++++------------------------------------ 1 file changed, 7 insertions(+), 63 deletions(-) (limited to 'drivers/media/dvb/ttpci/av7110.c') diff --git a/drivers/media/dvb/ttpci/av7110.c b/drivers/media/dvb/ttpci/av7110.c index 48e8097d843..b5d40d42436 100644 --- a/drivers/media/dvb/ttpci/av7110.c +++ b/drivers/media/dvb/ttpci/av7110.c @@ -177,9 +177,6 @@ static void init_av7110_av(struct av7110 *av7110) ret = av7110_set_volume(av7110, av7110->mixer.volume_left, av7110->mixer.volume_right); if (ret < 0) printk("dvb-ttpci:cannot set volume :%d\n",ret); - ret = av7110_setup_irc_config(av7110, 0); - if (ret < 0) - printk("dvb-ttpci:cannot setup irc config :%d\n",ret); } static void recover_arm(struct av7110 *av7110) @@ -265,60 +262,6 @@ static int arm_thread(void *data) } -/** - * Hack! we save the last av7110 ptr.
