      irq_domain: Remove irq_domain_add_simple() · 6b783f7c
      由 Grant Likely 提交于 
      irq_domain_add_simple() was a stop-gap measure until complete irq_domain
support was complete.  This patch removes the irq_domain_add_simple()
interface.

This patch also drops the explicit irq_domain initialization performed
by the mach-versatile code because the versatile interrupt controller
already has irq_domain support built into it.  This was a bug that was
hanging around quietly for a while, but with the full irq_domain which
actually verifies that irq_domain ranges are available it would cause
the registration to fail and the system wouldn't boot.

v4: Fixed number of irqs in mx5 gpio code
v2: Updated to pass in host_data pointer on irq_domain allocation.

      ARM: imx6: add missing twd_clk for imx6q clock · 5e540a5a
      由 Shawn Guo 提交于 
      With commit 5def51b0 (ARM: 7211/1: smp_twd: get the rate from a clock)
hitting mainline, if we do not have a twd_clk for lookup, we will see
the following error message in boot log.

 smp_twd: clock not found: -2

Actually we should add this clock regardless of the error message,
so that we can:

 * Avoid the local timer calibrating at boot time
 * Make the local timer cpufreq aware on imx6q

      ARM: Add arm_memblock_steal() to allocate memory away from the kernel · 716a3dc2
      由 Russell King 提交于 
      Several platforms are now using the memblock_alloc+memblock_free+
memblock_remove trick to obtain memory which won't be mapped in the
kernel's page tables.  Most platforms do this (correctly) in the
->reserve callback.  However, OMAP has started to call these functions
outside of this callback, and this is extremely unsafe - memory will
not be unmapped, and could well be given out after memblock is no
longer responsible for its management.

So, provide arm_memblock_steal() to perform this function, and ensure
that it panic()s if it is used inappropriately.  Convert everyone
over, including OMAP.

As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot
with this change.  Mark this option as BROKEN and make it depend on
BROKEN.  OMAP needs to be fixed, or 137d105d (ARM: OMAP4: Fix
errata i688 with MPU interconnect barriers.) reverted until such
time it can be fixed correctly.

      arm/imx: fix irq_base for gpio · 04aafd71
      由 Shawn Guo 提交于 
      When gpio core dynamically allocate gpio number for a port, it starts
from the end of the total range, 0 ~ ARCH_NR_GPIOS.  That said, the
earlier a port gets probed, the bigger gpio number it gets assigned.
To match this, the irq_base for gpio should be assigned from
'MXC_GPIO_IRQ_START + ARCH_NR_GPIOS' decreasingly.

      arm/imx: fix return type of callback passed to of_irq_init() · 2a3267a4
      由 Shawn Guo 提交于 
      The of_irq_init() expects the callback passed by .data of of_device_id
return 'int' instead of 'void'.  This patch fixes it to have
irq_init_cb() return the correct value, and in turn have the secondary
interrupt controller (gpio in this case) initialized properly and also
eliminate the error message 'of_irq_init: children remain, but no
parents' which was overlooked before.

SD/MMC cards.

arch_idle prepared for the cleanup.  It's suggested by Russel King
