In omap24xx_cpu_suspend assembly routine, the r2 register which holds the address of the SDRC_POWER reg is set to zero before the value is written back triggering a fault due to writing to address zero. It's hard to tell where this change was introduced since this file has been moved and merged. While this fix prevents a crash, suspend on my n810 is broken with current kernels. I never come out of suspend. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

By Ingo Molnar, interrupts are not masked by default. (refer to 76d21601) But if interrupts are not masked, the processor can wake up while in Suspend-to-RAM state by an external interrupt. For example, if an OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM state, it wake up automatically by M_IRQ_92. The disable_irq() function can't disable the interrupt in H/W level, So I modified arch/arm/mach-omap2/irq.c Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

When 32 kHz timer is used the min_delta_ns should be initialized so that it reflects the timer programming cost. A write to the timer device will be usually posted, but it takes roughly 3 cycles before it is effective. If the timer is reprogrammed before that, the CPU will stall until the previous write completes. This was pointed out by Richard Woodruff. Since the lower bound for min_delta_ns is 1000, the change is visible only with tick rates less than 3 MHz. Also note that the old value is incorrect for 32 kHz also due to a rounding error, and it can cause the timer queue to hang (due to clockevent code trying to program the timer with zero ticks).

A spin_lock deadlock will occur when omap_mcbsp_request() is invoked. omap_mcbsp_request() \- clk_enable(mcbsp->clk) [takes and holds clockfw_lock] \- omap2_clk_enable() \- _omap2_clk_enable() \- omap_mcbsp_clk_enable() \- clk_enable(child clock) [tries for clockfw_lock again] mcbsp_clk is a virtual clock and it comprises several child clocks. when enable mcbsp_clk in omap_mcbsp_request(), the enable function of mcbsp_clk will enable its child clocks, then the deadlock occurs. The solution is to remove the virtual clock and enable these child clocks in omap_mcbsp_request() directly.

When there are multiple L1-aliasing userland mappings of the same physical page, we currently remap each of them uncached, to prevent VIVT cache aliasing issues. (E.g. writes to one of the mappings not being immediately visible via another mapping.) However, when we do this remapping, there could still be stale data in the L2 cache, and an uncached mapping might bypass L2 and go straight to RAM. This would cause reads from such mappings to see old data (until the dirty L2 line is eventually evicted.) This issue is solved by forcing a L2 cache flush whenever the shared page is made L1 uncacheable. Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding for XSc3 doesn't appear to work in practice.

_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL. Thus it has to be masked out, if the BAT mapping should be non cacheable or CPU_FTR_NEED_COHERENT is not set. This will work on normal SMP setups because we force-set CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path.

This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders. This controller does not integrate the root hub, so this driver also fakes one-port hub. External hub is required to support more than one device.
