Before v3.1-rc1 the omapdss driver was managing clocks and resets correctly. However, when omapdss started using runtime PM at v3.1-rc1, the responsibility for the reset moved to HWMOD framework. HWMOD framework does not currently enable all the DSS clocks when resetting the DSS hardware. This causes the HWMOD frameworks boot-time reset to fail, possibly leaving the DSS hardware in undefined state. This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core. The flag is actually not used on OMAP4, because dss_core hardware does not have soft-reset functionality and thus the HWMOD framework never resets nor waits for the reset to finish. However, while the flag is not strictly needed currently, I think it represents the HW correctly: all the DSS clocks should be enabled after power-on to allow DSS hardware to finish its reset. A custom reset function will be added in the following patches which manages this correctly for OMAP4.

The clocks should be dss_48mhz_clk and dss_tv_clk, respectively. These problems were temporarily fixed with the DSS patches 9ede365aa6f74428a1f69c21ca1cf21213167576 ("HACK: OMAP: DSS2: clk hack for OMAP2/3"), and df5d3ed23cf73ee0763a8963003bda9b69d9620f ("OMAP: DSS2: HDMI: fix hdmi clock name"), which can be reverted after this patch.

The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the other DSS modules also, thus breaking the HWMOD model where every DSS module is handled independently. This fixes the problem with DSS reset on OMAP4, caused by the fact that because there's no SW reset for dss_core on OMAP4, the HWMOD framework doesn't try to reset dss_core and thus the DSS clocks were never enabled at the same time. This causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi. The common reset function will also allow us to fix another problem in the future: before doing a reset we need to disable DSS outputs, which are in some cases enabled by the bootloader, as otherwise DSS HW seems to get more or less stuck, requiring a power reset to recover.

Thus if the bootloader has enabled a display, the hwmod code cannot reset the DISPC module just like that, but the outputs need to be disabled first. Add function dispc_disable_outputs() which disables all active overlay manager and ensure all frame transfers are completed. Modify omap_dss_reset() to call this function and clear DSS_CONTROL, DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the DSS2 driver starts. This resolves the hang issue(caused by a L3 error during boot) seen on the beagle board C3, which has a factory bootloader that enables display. The issue is resolved with this patch.

While going through these headers, I was dismayed to find these: > > arch/arm/mach-s3c2410/include/mach/system.h:void (*s3c24xx_idle)(void); > arch/arm/plat-mxc/include/mach/system.h:extern void (*imx_idle)(void); > > when we have a perfectly good pm_idle hook already in place - so there's > no excuse for these especially when other platforms are already using > pm_idle to hook their platform specific idle function into. This is > something that better be gone at the next merge window!

This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.

In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.
