From 16b7b2ac0148e839da86af8747b6fa4aad43a9b7 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Tue, 24 Oct 2006 00:21:27 +0900 Subject: [MIPS] Fixup migration to GENERIC_TIME Since we already moved to GENERIC_TIME, we should implement alternatives of old do_gettimeoffset routines to get sub-jiffies resolution from gettimeofday(). This patch includes: * MIPS clocksource support (based on works by Manish Lachwani). * remove unused gettimeoffset routines and related codes. * remove unised 64bit do_div64_32(). * simplify mips_hpt_init. (no argument needed, __init tag) * simplify c0_hpt_timer_init. (no need to write to c0_count) * remove some hpt_init routines. * mips_hpt_mask variable to specify bitmask of hpt value. * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read. * convert ip27_do_gettimeoffset to ip27_hpt_read. * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read. * simplify sb1250 hpt functions. (no need to subtract and shift) Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle --- arch/mips/dec/time.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'arch/mips/dec/time.c') diff --git a/arch/mips/dec/time.c b/arch/mips/dec/time.c index 4cf0c06e2414..69e424e9ab6f 100644 --- a/arch/mips/dec/time.c +++ b/arch/mips/dec/time.c @@ -160,11 +160,6 @@ static unsigned int dec_ioasic_hpt_read(void) return ioasic_read(IO_REG_FCTR); } -static void dec_ioasic_hpt_init(unsigned int count) -{ - ioasic_write(IO_REG_FCTR, ioasic_read(IO_REG_FCTR) - count); -} - void __init dec_time_init(void) { @@ -174,11 +169,9 @@ void __init dec_time_init(void) mips_timer_state = dec_timer_state; mips_timer_ack = dec_timer_ack; - if (!cpu_has_counter && IOASIC) { + if (!cpu_has_counter && IOASIC) /* For pre-R4k systems we use the I/O ASIC's counter. */ mips_hpt_read = dec_ioasic_hpt_read; - mips_hpt_init = dec_ioasic_hpt_init; - } /* Set up the rate of periodic DS1287 interrupts. */ CMOS_WRITE(RTC_REF_CLCK_32KHZ | (16 - __ffs(HZ)), RTC_REG_A); -- cgit v1.2.3-59-g8ed1b
