From a8135fcfd0431eda3653c7069e7aefc8674fdfbe Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Sun, 15 Jul 2007 20:12:23 +0100 Subject: [PATCH 01/58] [ARM] 4476/1: EM7210/SS4000E support This patch adds the basic support for the em7210 board. It is similar to the iq31244 board and can be found on Intel "Baxter Creek" ss4000e nas.

Details: * iop13xx supports disabling the timer while iop3xx does not. This requires a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code. * The heartbeat interval is derived from the internal bus clock rate, so this this patch also exports the tick rate to the iop_wdt driver.

void (*save)(unsigned long *); void (*restore)(unsigned long *); int (*valid)(suspend_state_t state); void (*enter)(suspend_state_t state); } 2. processor specific registers saving and restoring are performed by calling the corresponding (*save) and (*restore) 3. pxa_cpu_pm_fns->save_size should be initialized to the required size for processor specific registers saving, the allocated memory address will be passed to (*save) and (*restore) memory allocation happens early in pxa_pm_init(), and save_size should be assigned prior to this (which is usually true, since pxa_pm_init() happens in device_initcall() 4. there're some redundancies for those SLEEP_SAVE_XXX and related macros, will be fixed later, one way possible is for the system devices to handle the specific registers saving and restoring Signed-off-by: eric miao Signed-off-by: Russell King --- arch/arm/mach-pxa/pm.c | 169 +++++++++------------------------- arch/arm/mach-pxa/pxa25x.c | 84 ++++++++++++++++- arch/arm/mach-pxa/pxa27x.c | 117 +++++++++++++++++++++-- include/asm-arm/arch-pxa/pm.h | 11 ++- 4 files changed, 244 insertions(+), 137 deletions(-) diff --git a/arch/arm/mach-pxa/pm.c b/arch/arm/mach-pxa/pm.c index e66dbc26add1..b59a81a8e7d3 100644 --- a/arch/arm/mach-pxa/pm.c +++ b/arch/arm/mach-pxa/pm.c @@ -24,61 +24,13 @@ #include #include - -/* - * Debug macros - */ -#undef DEBUG - -#define SAVE(x) sleep_save[SLEEP_SAVE_##x] = x -#define RESTORE(x) x = sleep_save[SLEEP_SAVE_##x] - -#define RESTORE_GPLEVEL(n) do { \ - GPSR##n = sleep_save[SLEEP_SAVE_GPLR##n];

When talking to the MCU the general procedure is to start MCU, send command (using ssp_inout(command)), the proper reply is always TXDUMMY. After receiving TXDUMMY you can send the value you wish pushed (for example brightness level). End with ssp_end() so the spinlock gets unlocked.

According to + * Nico's comment in the previous version of this + * code, experience has shown that 6 OSCR ticks is + * "very close" but he went with 8. We will use 16, + * based on the results of testing on PXA270. + * + * To be doubly sure, we also tell clkevt via + * clockevents_register_device() not to ask for + * anything that might put us "very close". */ +#define MIN_OSCR_DELTA 16 do { - timer_tick(); - OSSR = OSSR_M0; /* Clear match on timer 0 */ + OSSR = OSSR_M0; next_match = (OSMR0 += LATCH); - } while( (signed long)(next_match - OSCR) <= 8 ); - - write_sequnlock(&xtime_lock); + c->event_handler(c); + } while (((signed long)(next_match - OSCR) <= MIN_OSCR_DELTA) + && (c->mode == CLOCK_EVT_MODE_PERIODIC)); + } return IRQ_HANDLED; } -static struct irqaction pxa_timer_irq = { - .name = "PXA Timer Tick", - .flags = IRQF_DISABLED | IRQF_TIMER | IRQF_IRQPOLL, - .handler = pxa_timer_interrupt, +static int +pxa_osmr0_set_next_event(unsigned long delta, struct clock_event_device *dev) +{ + unsigned long irqflags; + + raw_local_irq_save(irqflags); + OSMR0 = OSCR + delta; + OSSR = OSSR_M0; + OIER |= OIER_E0; + raw_local_irq_restore(irqflags); + return 0; +} + +static void +pxa_osmr0_set_mode(enum clock_event_mode mode, struct clock_event_device *dev) +{ + unsigned long irqflags; + + switch (mode) { + case CLOCK_EVT_MODE_PERIODIC: + raw_local_irq_save(irqflags); + OSMR0 = OSCR + LATCH; + OSSR = OSSR_M0; + OIER |= OIER_E0; + raw_local_irq_restore(irqflags); + break; + + case CLOCK_EVT_MODE_ONESHOT: + raw_local_irq_save(irqflags); + OIER &= ~OIER_E0; + raw_local_irq_restore(irqflags); + break; + + case CLOCK_EVT_MODE_UNUSED: + case CLOCK_EVT_MODE_SHUTDOWN: + /* initializing, released, or preparing for suspend */ + raw_local_irq_save(irqflags); + OIER &= ~OIER_E0; + raw_local_irq_restore(irqflags); + break; + } +} + +static struct clock_event_device ckevt_pxa_osmr0 = { + .name = "osmr0", + .features = CLOCK_EVT_FEAT_PERIODIC | CLOCK_EVT_FEAT_ONESHOT, + .shift = 32, + .rating = 200, + .cpumask = CPU_MASK_CPU0, + .set_next_event = pxa_osmr0_set_next_event, + .set_mode = pxa_osmr0_set_mode, }; -static cycle_t pxa_get_cycles(void) +static cycle_t pxa_read_oscr(void) { return OSCR; } -static struct clocksource clocksource_pxa = { - .name = "pxa_timer", +static struct clocksource cksrc_pxa_oscr0 = { + .name = "oscr0", .rating = 200, - .read = pxa_get_cycles, + .read = pxa_read_oscr, .mask = CLOCKSOURCE_MASK(32), .shift = 20, .flags = CLOCK_SOURCE_IS_CONTINUOUS, }; +static struct irqaction pxa_ost0_irq = { + .name = "ost0", + .flags = IRQF_DISABLED | IRQF_TIMER | IRQF_IRQPOLL, + .handler = pxa_ost0_interrupt, + .dev_id = &ckevt_pxa_osmr0, +}; + static void __init pxa_timer_init(void) { - struct timespec tv; - unsigned long flags; + OIER = 0; + OSSR = OSSR_M0 | OSSR_M1 | OSSR_M2 | OSSR_M3; - set_rtc = pxa_set_rtc; + ckevt_pxa_osmr0.mult = + div_sc(CLOCK_TICK_RATE, NSEC_PER_SEC, ckevt_pxa_osmr0.shift); + ckevt_pxa_osmr0.max_delta_ns = + clockevent_delta2ns(0x7fffffff, &ckevt_pxa_osmr0); + ckevt_pxa_osmr0.min_delta_ns = + clockevent_delta2ns(MIN_OSCR_DELTA, &ckevt_pxa_osmr0) + 1; - OIER = 0; /* disable any timer interrupts */ - OSSR = 0xf; /* clear status on all timers */ - setup_irq(IRQ_OST0, &pxa_timer_irq); - local_irq_save(flags); - OIER = OIER_E0; /* enable match on timer 0 to cause interrupts */ - OSMR0 = OSCR + LATCH; /* set initial match */ - local_irq_restore(flags); + cksrc_pxa_oscr0.mult = + clocksource_hz2mult(CLOCK_TICK_RATE, cksrc_pxa_oscr0.shift); - /* - * OSCR runs continuously on PXA and is not written to, - * so we can use it as clock source directly. - */ - clocksource_pxa.mult = - clocksource_hz2mult(CLOCK_TICK_RATE, clocksource_pxa.shift); - clocksource_register(&clocksource_pxa); + setup_irq(IRQ_OST0, &pxa_ost0_irq); + + clocksource_register(&cksrc_pxa_oscr0); + clockevents_register_device(&ckevt_pxa_osmr0); } -#ifdef CONFIG_NO_IDLE_HZ -static int pxa_dyn_tick_enable_disable(void) -{ - /* nothing to do */ - return 0; -} - -static void pxa_dyn_tick_reprogram(unsigned long ticks) -{ - if (ticks > 1) { - initial_match = OSMR0; - OSMR0 = initial_match + ticks * LATCH; - match_posponed = 1; - } -} - -static irqreturn_t -pxa_dyn_tick_handler(int irq, void *dev_id) -{ - if (match_posponed) { - match_posponed = 0; - OSMR0 = initial_match; - if ( (signed long)(initial_match - OSCR) <= 8 ) - return pxa_timer_interrupt(irq, dev_id); - } - return IRQ_NONE; -} - -static struct dyn_tick_timer pxa_dyn_tick = { - .enable = pxa_dyn_tick_enable_disable, - .disable = pxa_dyn_tick_enable_disable, - .reprogram = pxa_dyn_tick_reprogram, - .handler = pxa_dyn_tick_handler, -}; -#endif - #ifdef CONFIG_PM static unsigned long osmr[4], oier; @@ -191,7 +189,10 @@ static void pxa_timer_resume(void) OIER = oier; /* - * OSMR0 is the system timer: make sure OSCR is sufficiently behind + * OSCR0 is the system timer, which has to increase + * monotonically until it rolls over in hardware.

The bare-bones MX31 support in this patch boots to the rootdev panic with 8250 serial console configured "console=ttyS0,115200". It assumes that Redboot is the boot loader.

531b617c71e780b14af5931428e0611f930c2134 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Sun, 22 Jul 2007 16:05:25 +0100 Subject: [PATCH 42/58] [ARM] 4508/1: S3C: Move items to include/asm-arm/plat-s3c This patch moves items of the s3c24xx support into a new plat-s3c directory for items that use the s3c24xx support but are not directly s3c24xx compatible, such as the s3c2400 and s3c6400. git mv
