From 659f6de01c8db2a4d84800c14cda9816821a1e11 Mon Sep 17 00:00:00 2001 From: Thierry MERLE Date: Mon, 1 Sep 2008 22:32:10 +0200 Subject: b2c2 and bt8xx: udelay to mdelay From: Thierry MERLE b2c2-flexcop, dvb/bt8xx and video/bt8xx fails to build on ARM with: __bad_udelay is specifically designed on ARM to fail when udelay is called in a bad way. arch/arm/include/asm/delay.h has this to say about __bad_udelay: /* * This function intentionally does not exist; if you see references to * it, it means that you're calling udelay() with an out of range value. * * With currently imposed limits, this means that we support a max delay * of 2000us. Further limits: HZ<=1000 and bogomips<=3355 */ extern void __bad_udelay(void); Solution is to replace udelay by a mdelay and udelay with value less than 2000 Priority: high Signed-off-by: Thierry MERLE --- linux/drivers/media/dvb/b2c2/flexcop-fe-tuner.c | 3 ++- linux/drivers/media/dvb/bt8xx/dst.c | 4 ++-- 2 files changed, 4 insertions(+), 3 deletions(-) (limited to 'linux/drivers/media/dvb') diff --git a/linux/drivers/media/dvb/b2c2/flexcop-fe-tuner.c b/linux/drivers/media/dvb/b2c2/flexcop-fe-tuner.c index f9d087669..4eed783f4 100644 --- a/linux/drivers/media/dvb/b2c2/flexcop-fe-tuner.c +++ b/linux/drivers/media/dvb/b2c2/flexcop-fe-tuner.c @@ -137,7 +137,8 @@ static int flexcop_send_diseqc_msg(struct dvb_frontend* fe, int len, u8 *msg, un flexcop_diseqc_send_byte(fe, 0xff); else { flexcop_set_tone(fe, SEC_TONE_ON); - udelay(12500); + mdelay(12); + udelay(500); flexcop_set_tone(fe, SEC_TONE_OFF); } msleep(20); diff --git a/linux/drivers/media/dvb/bt8xx/dst.c b/linux/drivers/media/dvb/bt8xx/dst.c index a7637562e..aa3db57d3 100644 --- a/linux/drivers/media/dvb/bt8xx/dst.c +++ b/linux/drivers/media/dvb/bt8xx/dst.c @@ -1244,7 +1244,7 @@ static int dst_command(struct dst_state *state, u8 *data, u8 len) goto error; } if (state->type_flags & DST_TYPE_HAS_FW_1) - udelay(3000); + mdelay(3); if (read_dst(state, &reply, GET_ACK)) { dprintk(verbose, DST_DEBUG, 1, "Trying to recover..
