Since imx6sx-sdb reva board is experimental and will not be used formally (eg, no software release based on it), we set revb board as the formal imx6sx-sdb board. The imx6sx-sdb uses pfuse200 as pmic which has only one power supply for both VDDARM_IN and VDDSOC_IN, so VDDARM_IN and VDDSOC_IN have to use the same (higher one in the same frequency) one as its power supply, that's the reason we override the OPP setting in board dts file.

The imx6sx sdb board has two revisions, the current mainline one is reva which is experimental and mainly for internal use. In this commit, we rename imx6sx-sdb.dts to imx6sx-sdb.dtsi, and move the reva dedicated contents to imx6sx-sdb-reva.dts.

When generic pm domain support is enabled, the PGC can be used to completely gate power to the PU power domain containing GPU3D, GPU2D, and VPU cores. This code triggers the PGC powerdown sequence to disable the GPU/VPU isolation cells and gate power and then disables the PU regulator. To reenable, the reverse powerup sequence is triggered after the PU regulator is enabled again. The GPU and VPU devices in the PU power domain temporarily need to be clocked during powerup, so that the reset machinery can work.

This adds support for Vybrid's interrupt router. On VF6xx models, almost all peripherals can be used by either of the two CPU's, the Cortex-A5 or the Cortex-M4. The interrupt router routes the peripheral interrupts to the configured CPU. This IRQ chip driver configures the interrupt router to route the requested interrupt to the CPU the kernel is running on. The driver makes use of the irqdomain hierarchy support. The parent is given by the device tree. This should be one of the two possible parents either ARM GIC or the ARM NVIC interrupt controller. The latter is currently not yet supported. Note that there is no resource control mechnism implemented to avoid concurrent access of the same peripheral. The user needs to make sure to use device trees which assign the peripherals orthogonally. However, this driver warns the user in case the interrupt is already configured for the other CPU. This provides a poor man's resource controller.

The CG8 field of the CCM CCGR3 register is the 'mipi_core_cfg' gate clock, according to the i.MX6q/sdl reference manuals. This clock is actually the gate for several clocks, including the ipg clock's output. The MIPI DSI host controller embedded in the i.MX6q/sdl SoCs takes the ipg clock as the pclk - the APB clock signal . In order to gate/ungate the ipg clock, this patch adds a new shared clock gate named as "mipi_ipg". Signed-off-by: Liu Ying <Ying.Liu@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

There doesn't seem to be any valid reason to allocate the pages array with the same flags as the buffer itself. Doing so can eventually lead to the following safeguard in mm/slab.c's cache_grow() to be hit: if (unlikely(flags & GFP_SLAB_BUG_MASK)) { pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK); BUG(); } This happens when buffers are allocated with __GFP_DMA32 or __GFP_HIGHMEM. Fix this by allocating the pages array with GFP_KERNEL to follow what is done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer() is safe because atomic allocations are handled by __iommu_alloc_atomic().

The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.

davinci_cfg_reg gets called from a lot of locations that might get called after the init section has been discarded, so the function itself must not be marked __init either.
