ARC: Don't try to use value of top level clock-frequency in DT

2016-05-09T04:02:30Z

We no longer use it and instead a real clk device such as fixed-clk instance is fed to timers etc. Signed-off-by: Alexey Brodkin [vgupta: broken out of a bigger patch, rewrote changelog] Signed-off-by: Vineet Gupta

ARC: clocksource: DT based probe

2016-05-09T04:02:30Z

- Remove explicit clocksource setup and let it be done by OF framework by defining CLOCKSOURCE_OF_DECLARE() for various timers - This allows multiple clocksources to be potentially registered simultaneouly: previously we could only do one - as all of them had same arc_counter_setup() routine for registration - Setup routines also ensure that the underlying timer actually exists. - Remove some of the panic() calls if underlying timer is NOT detected as fallback clocksource might still be available 1. If GRFC doesn't exist, jiffies clocksource gets registered anyways 2. if RTC doesn't exist, TIMER1 can take over (as it is always present) Cc: Daniel Lezcano Signed-off-by: Vineet Gupta

ARC: clockevent: Prepare for DT based probe

2016-05-09T04:02:29Z

- call clocksource_probe() - This in turns needs of_clk_init() to be called earlier Cc: Daniel Lezcano Signed-off-by: Noam Camus [vgupta: broken off from a bigger patch] Signed-off-by: Vineet Gupta

ARCv2: ioremap: Support dynamic peripheral address space

2016-03-19T09:04:10Z

The peripheral address space is architectural address window which is uncached and typically used to wire up peripherals. For ARC700 cores (ARCompact ISA based) this was fixed to 1GB region 0xC000_0000 - 0xFFFF_FFFF. For ARCv2 based HS38 cores the start address is flexible and can be 0xC, 0xD, 0xE, 0xF 000_000 by programming AUX_NON_VOLATILE_LIMIT reg (typically done in bootloader) Further in cas of PAE, the physical address can extend beyond 4GB so need to confine this check, otherwise all pages beyond 4GB will be treated as uncached Signed-off-by: Vineet Gupta

arc: use of_platform_default_populate() to populate default bus

2016-03-17T12:15:15Z

Use helper of_platform_default_populate() in linux/of_platform when possible, instead of calling of_platform_populate() with the default match table. Signed-off-by: Kefeng Wang Signed-off-by: Vineet Gupta

ARCv2: boot report CCMs (Closely Coupled Memories)

2016-02-18T12:00:18Z

- ARCv2 uses a seperate BCR for {I,D}CCM base address: ARCompact encoded both base/size in same BCR - Size encoding in common BCR is different for ARCompact/ARCv2 Signed-off-by: Vineet Gupta

ARC: Assume multiplier is always present

2016-02-18T12:00:03Z

It is unlikely that designs running Linux will not have multiplier. Further the current support is not complete as tool don't generate a multilib w/o multiplier. Signed-off-by: Vineet Gupta

ARCv2: Check for LL-SC livelock only if LLSC is enabled
