[PATCH v4 0/7] add initial imx6q support

[shawn.guo@linaro.org (Shawn Guo)]

This patch series adds the initial support for imx6q, which is a
Cortex-A9 Quad Core based SoC.

We chose to add imx6q support into mach-imx other than mach-mx5 or
a new mach-mx6, because we intend to merge mach-mx5 into mach-imx, so
that we have only mach-imx for imx family.

It's based on linux-next-20110926 with some prerequisite patches
not showing up on linux-next applied.

Changes since v3:
 * Fold the gic_handle_irq (local to imx) support patch in the series.
   It can be replaced by Marc Zyngier's global gic_handle_irq support
   with a little rework if his PPI and MULTI_IRQ_HANDLER series gets
   merged.

Changes since v2:
 * Refine the L2 register save/restore implementation per Lorenzo's
   suggestion
 * Rebase to Rob's latest GIC OF bindings series
 * Rebase to Sascha's MULTI_IRQ_HANDLER support series

Changes since v1:
 * Use the existing IMX_IO_P2V for static mapping
 * Fix the MXC_INTERNAL_IRQS breakage introduced by GIC definition
 * Retrieve clock frequency for fixed clocks from device tree
 * Drop early_initcall from imx_src_init() and call it from imx6q
   platform initialization
 * Use readl_relaxed/writel_relaxed rather than __raw_readl/__raw_writel
   as suggested by Arnd
 * Kill unnecessary imx_local_timer_pre_suspend/resume functions
 * Kill Kconfig symbol MACH_IMX6Q
 * Rebase to rmk's "Add L2 cache cleaning to generic CPU suspend" series
   so that we can retain L2 cache with necessary L2 register
   save/restore across suspend/resume cycle
 * Rebase to Rob's new "GIC OF bindings" series

Thanks.
