The hardware reset value of bit CCM_CLPCR_LPM enables WAIT mode (WAIT_UNCLOCKED) by default. However this is undesirable because WAIT mode should only be enabled when there is a driver managing ARM clock gating. Correct the initial power mode to WAIT_CLOCKED (disable WAIT mode).

2013-01-14ARM: imx: disable cpu in .cpu_kill hookShawn Guo3-4/+8
It's buggy to disable the cpu that is being hot-unplugged in .cpu_die hook which runs on the cpu itself. Instead, it should be done in .cpu_kill which runs on the thread (another cpu) that asks for shutting down the cpu. Move imx_enable_cpu(cpu, false) call into .cpu_kill hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die, so that we can get a more stable cpu hot-plug operation.

2013-01-08arm: mvebu: use global interrupts for GPIOs on Armada XPThomas Petazzoni3-32/+24
The Armada XP GPIO controller has two ways of notifying interrupts: using global interrupts or using per-CPU interrupts. In an attempt to use the best available features, the 'marvell,armadaxp-gpio' compatible string selects a variant of the gpio-mvebu driver that makes use of the per-CPU interrupts. Unfortunately, this doesn't work properly in a SMP context, because we fall into cases where the GPIO interrupt is enabled on CPU X at the GPIO controller level, but on CPU Y at the interrupt controller level. It is not yet clear how to fix that easily. So for 3.8, our approach is to switch to global interrupts for GPIOs, so that we do not fall into this per-CPU interrupts problem. This patch therefore fixes GPIO interrupts on Armada XP platforms. Without this patch, GPIO interrupts simply do not work reliably, because their proper operation depends on which CPU the code requesting the interrupt is running.

2013-01-07ARM: highbank: fix secondary boot and hotplugRob Herring2-12/+2
With commit 384a290 (ARM: gic: use a private mapping for CPU target interfaces), wake-up IPIs now go to all cores as the gic cpu interface numbering may not follow core numbering. This broke secondary boot on highbank since the boot address was already set for all secondary cores, this caused all cores to boot before the kernel was ready. Fix this by moving the setting of the jump address to highbank_boot_secondary instead of highbank_smp_prepare_cpus and highbank_cpu_die. Also, clear the address when we boot. This prevents cores from booting before they are actually triggered and is also necessary to get suspend/resume to work.

2013-01-06dma: mv_xor: fix error handling for clocksThomas Petazzoni1-2/+5
When a channel fails to initialize, we release all ressources, including clocks. However, a XOR unit is not necessarily associated to a clock (some variants of Marvell SoCs have a clock for XOR units, some don't), so we shouldn't unconditionally be releasing the clock. Instead, just like we do in the mv_xor_remove() function, we should check if one clock was found before releasing it.

When mv_xor_channel_add() fails for one XOR channel, we jump to the err_channel_add label to clean up all previous channels that had been initialized correctly. Unfortunately, while handling this error condition, we were disposing the IRQ mapping before calling mv_xor_channel_remove() (which does the free_irq()), which is incorrect. Instead, do things properly in the reverse order of the initialization: first remove the XOR channel (so that free_irq() is done), and then dispose the IRQ mapping. This avoids ugly warnings when for some reason one of the XOR channel fails to initialize.

In the compatible field we should point the manufacturer of the board, which in this case is Buglabs. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-01-04clk: imx: Remove 'clock-output-names' from the examplesFabio Estevam4-18/+0
'clock-output-names' is not used in any of the dts/dtsi files for i.mx. Remove it from the examples, so that the example and the real usage in the dtsi files can match.

2013-01-03ARM: nomadik: bump the IRQ numbers againLinus Walleij1-39/+39
Bump the IRQ numbers from offset at 1 (right above NO_IRQ) to 32. This is the painful way to learn that if you're using SPARSE_IRQ and avoid to define .nr_irqs in your machine, the first 16 IRQs will be pre-allocated, and the IRQdomain code (as the VIC core code before it) will then assume that all IRQ descriptors are pre-allocated, and 16 of them are - by somebody else. So mapping the IRQs will fail in irq_create_mapping(). Moving the offset upward rids us of this problem.
