* ARM: call of_clk_init from default time_init handlerSebastian Hesselbarth2013-09-291-12/+17
| | | | | | | | | | | | | Most DT ARM machs require common clock providers initialized before timers. Currently, arch/arm machs use .init_time to call of_clk_init right before clocksource_of_init. This prevents to remove that callback and use the default one instead. This patch adds a call to of_clk_init() to the default .init_time callback for COMMON_CLK enabled machs to allow to remove custom callbacks where applicable. While at it, also reorder includes alphabetically. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

To allow consolidation of DT driven .time_init, move of_clock_init() to a temporary .time_init callback that will be removed when arch-wide callback is available. With previous pmc_base parsing helper for vt8500 clock providers, we can also safely remove the call to vtwm_clk_init() and get rid of some includes.

* ARM: tegra: split tegra_pmc_init() in twoStephen Warren2013-09-174-23/+35
| | | | | | | | | | | | | | | | | | | | | | | | | Tegra's board file currently initializes clocks much earlier than those for most other ARM SoCs. The reason is: * The PMC HW block is involved in the path of some interrupts (i.e. it inverts, or not, the IRQ input pin dedicated to the PMIC). * So, that part of the PMC must be initialized early so that the IRQ polarity is correct. * The PMC initialization is currently monolithic, and the PMC has some clock inputs, so the init routine ends up calling of_clk_get_by_name(), and hence clocks must be set up early too. In order to defer clock initialization to the more typical location, split out the portions of tegra_pmc_init() that are truly IRQ-related into a separate tegra_pmc_init_irq(), which can be called from the machine descriptor's .init_irq() function, and defer the rest until the machine descriptor's .init_machine() function. This allows the clock initiliazation to happen from the machine descriptor's .init_time() function, as is typical. Signed-off-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a cpu goes to a deep idle state where its local timer is shutdown, it notifies the time frame work to use the broadcast timer instead. Unfortunately, the broadcast device could wake up any CPU, including an idle one which is not concerned by the wake up at all. This implies, in the worst case, an idle CPU will wake up to send an IPI to another idle cpu. This patch fixes this for ARM platforms using timer-sp, by setting CLOCK_EVT_FEAT_DYNIRQ feature.

Unlike ordinary I/O ASIC interrupts DMA interrupts need to be deasserted by software by writing 0 to the respective bit in I/O ASIC's System Interrupt Register (SIR), similarly to how CP0.Cause.IP0 and CP0.Cause.IP1 bits are handled in the CPU (the difference is SIR DMA interrupt bits are R/W0C so there's no need for an RMW cycle). Otherwise the handler is reentered over and over again. The only current user is the DEC LANCE Ethernet driver and its extremely uncommon DMA memory error handler that does not care when exactly the interrupt is cleared. Anticipating the use of DMA interrupts by the Zilog SCC driver this change however exports clear_ioasic_dma_irq for device drivers to choose the right application-specific sequence to clear the request explicitly rather than calling it implicitly in the .irq_eoi handler of `struct irq_chip'. Previously these interrupts were cleared in the .end handler of the said structure, before it was removed. Signed-off-by: Maciej W.

Therefore we cannot unconditionally use it as a clock source. Fortunately if not implemented its register slot has a fixed value so it is enough if we check for the value at the end of the calibration period being the same as at the beginning. This also means we need to look for another high-precision clock source on the systems affected. The 5000/1xx can have an R4000SC processor installed where the CP0 Count register can be used as a clock source. Unfortunately all the R4k DECstations suffer from the missed timer interrupt on CP0 Count reads erratum, so we cannot use the CP0 timer as a clock source and a clock event both at a time. However we never need an R4k clock event device because all DECstations have a DS1287A RTC chip whose periodic interrupt can be used as a clock source. This gives us the following four configuration possibilities for I/O ASIC DECstations: 1. No I/O ASIC counter and no CP0 timer, e.g. R3k 5000/1xx (3MIN). 2. No I/O ASIC counter but the CP0 timer, i.e. R4k 5000/150 (4MIN). 3. The I/O ASIC counter but no CP0 timer, e.g. R3k 5000/240 (3MAX+). 4. The I/O ASIC counter and the CP0 timer, e.g. R4k 5000/260 (4MAX+). For #1 and #2 this change stops the I/O ASIC free-running counter from being installed as a clock source of a 0Hz frequency. For #2 it also arranges for the CP0 timer to be used as a clock source rather than a clock event device, because having an accurate wall clock is more important than a high-precision interval timer. For #3 there is no change. For #4 the change makes the I/O ASIC free-running counter installed as a clock source so that the CP0 timer can be used as a clock event device. Unfortunately the use of the CP0 timer as a clock event device relies on a succesful completion of c0_compare_interrupt. That never happens, because while waiting for a CP0 Compare interrupt to happen the function spins in a loop reading the CP0 Count register. This makes the CP0 Count erratum trigger reliably causing the interrupt waited for to be lost in all cases. As a result #4 resorts to using the CP0 timer as a clock source as well, just as #2. However we want to keep this separate arrangement in case (hope) c0_compare_interrupt is eventually rewritten such that it avoids the erratum. Signed-off-by: Maciej W.
