[PATCH v2 0/6] add initial imx6q support

[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 v3.1-rc6 with the patches below applied.

 * [PATCH v2 0/5] Convert DEBUG_LL UART selection to a Kconfig choice
   http://thread.gmane.org/gmane.linux.ports.arm.kernel/129702

 * [PATCH v4 2/2] ARM: l2x0: Add OF based initialization
   http://article.gmane.org/gmane.linux.kernel/1164401

 * [PATCH 1/7] ARM: l2x0: add empty l2x0_of_init
   http://article.gmane.org/gmane.linux.ports.arm.kernel/130878

 * [PATCH 0/5] GIC OF bindings
   http://thread.gmane.org/gmane.linux.drivers.devicetree/8093/

For suspend/resume support, it needs the following extra patches as the
prerequisite.

 * [PATCH 00/11] Add L2 cache cleaning to generic CPU suspend
   http://thread.gmane.org/gmane.linux.ports.arm.kernel/130957/

 * [PATCH v2 0/5] CPU PM notifiers
   http://thread.gmane.org/gmane.linux.ports.arm.kernel/131212/focus=131353

 * [PATCH v2 2/2] ARM: smp_scu: remove __init annotation from
   scu_enable()
   http://permalink.gmane.org/gmane.linux.ports.arm.kernel/131358

I hope I have made all changes I agree to change.  But please let me
know if I missed any.

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.
