| | | | | | | | | | | | | | | | | | | | | | | | DT node's unit address should be its own register offset address to make it a unique across the system. This patch corrects the incorrect USB entries with correct register offset for unit address.

| * ARM: dts: omap4/5: Use l3_ick for the gpmc nodeFlorian Vaussard2014-03-132-0/+4
| | | | | | | | | | | | | | | | | | | | | | The GPMC clock is derived from l3_ick. The simplest solution is to reference directly l3_ick to provide the GPMC fck in order to get correct timings. The real management of the clock is left to hwmod. Cc: stable@vger.kernel.org # v3.14+ Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Tony Lindgren <tony@atomide.com>
| * CLK: TI: OMAP4/5/DRA7: Remove gpmc_fck from dummy clocksFlorian Vaussard2014-03-133-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When arch/arm/mach-omap2/gpmc.c calls clk_get(..., "fck"), it will get a dummy clock and try to use it. As the rate is configured to zero, this will result in several divisions by zero, and misconfigured timings, with devices on the bus being lost in the La La Land. It is better to remove gpmc_fck from the dummy clocks, so that gpmc.c can fail gracefully.

| * ARM: OMAP2+: INTC: Acknowledge stuck active interruptsStefan Sørensen2014-03-131-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an interrupt has become active on the INTC it will stay active until it is acked, even if masked or de-asserted. The INTC_PENDING_IRQn registers are however updated and since these are used by omap_intc_handle_irq to determine which interrupt to handle, it will never see the active interrupt. This will result in a storm of useless interrupts that is only stopped when another higher priority interrupt is asserted. Fix by sending the INTC an acknowledge if we find no interrupts to handle.

There is code in the regulator core to deal with situations where no regulator is specified and provide a dummy, but that works on DT-based boards only. The situation can be remedied by adding a dummy regulator during board initialization.

What the bug is: There is a problem caused by an invalid calculation of n_voltages in the driver. This n_voltages value has the potential to be different for each regulator. The value for linear_min_sel is set as DA9063_V##regl_name# which can be different depending upon the regulator. This is chosen according to the following definitions in the DA9063 registers.h file: DA9063_VLDO1_BIAS 0 DA9063_VLDO2_BIAS 0 DA9063_VLDO3_BIAS 0 DA9063_VLDO4_BIAS 0 DA9063_VLDO5_BIAS 2 DA9063_VLDO6_BIAS 2 DA9063_VLDO7_BIAS 2 DA9063_VLDO8_BIAS 2 DA9063_VLDO9_BIAS 3 DA9063_VLDO10_BIAS 2 DA9063_VLDO11_BIAS 2 The calculation for n_voltages is valid for LDOs whose BIAS value is zero but this is not correct for those LDOs which have a non-zero value. What the fix is: In order to take into account the non-zero linear_min_sel value which is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and LDO11, the calculation for n_voltages should take into account the missing term defined by DA9063_V##regl_name#. This will in turn allow the core constraints calculation to set the maximum voltage limits correctly and therefore allow users to apply the maximum expected voltage to all of the LDOs.

However, now there are systems that may register multiple sched_clock sources, for which the lack of locking has casued problems: If two sched_clock sources are registered we may end up in a situation where a call to sched_clock() may be accessing the epoch cycle count for the old counter and the cycle count for the new counter. This can lead to confusing results where sched_clock() values jump and then are reset to 0 (due to the way the registration function forces the epoch_ns to be 0). Fix this by reorganizing the registration function to hold the seqlock for as short a time as possible while we update the clock_data structure for a new counter. We also put any accumulated time into epoch_ns instead of resetting the time to 0 so that the clock doesn't reset after each successful registration.
