video: move Versatile CLCD helpers

2014-06-27T08:15:22+00:00

This moves the Versatile-specific helper code and panel database
down into the drivers/video folder next to the CLCD driver
itself, preserving the config symbol but also moving the header
to platform data.

This is necessary to rid the Integrator of this final 
inclusion dependency and get us one less user of the
plat-versatile folder.

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next

2014-06-05T22:57:04+00:00

Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

ARM: 8025/1: Get rid of meminfo

2014-06-01T00:17:12+00:00

memblock is now fully integrated into the kernel and is the prefered
method for tracking memory. Rather than reinvent the wheel with
meminfo, migrate to using memblock directly instead of meminfo as
an intermediate.

ARM: plat-versatile: convert LEDs to platform device

2014-02-27T13:56:19+00:00

The LEDs were initialized unconditionally with an fs_initcall()
which doesn't play well with multiplatform. Convert the driver
to a platform device and convert all boards with these LEDs
to register a platform device and pass the register as a
resource instead.

Tested successfully on the Versatile/AB and RealView PB1176.

ARM: remove mach .handle_irq for GIC users

2013-01-12T16:47:20+00:00

Now that the GIC initialization sets up the handle_arch_irq pointer, we
can remove it for all machines and make it static.

clk: convert ARM RealView to common clk

2012-08-25T00:42:10+00:00

This converts the ARM RealView machine over to using the common
clock. The approach is similar to the one used for the Integrator,
and we're reusing the ICST wrapper code.

We have to put the clock intialization in the timer init function
for the clocks to be available when initializing the timer,
keeping them in early_init() is too early for the common clk.

Since we now have to go down and compile drivers/clk/versatile
a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper
code gets compiled into the kernel for either machine. A leftover
CLK_VERSATILE in the Integrator Kconfig was fixed up to use
the new symbol as well.

Tested on ARM RealView PB1176.

ARM: mach-realview and mach-versatile: retire custom LED code

2012-08-01T03:22:04+00:00

This replaces the custom LED trigger code in mach-realview with
some overarching platform code for the plat-versatile family that
will lock down LEDs 2 thru 5 for CPU activity indication. The
day we have 8 core ARM systems the plat-versatile code will have
to become more elaborate.

Tested on RealView PB11MPCore by invoking four different CPU
hogs (yes > /dev/null&) and see the LEDs go on one at a time.
They all go off as the hogs are killed. Tested on the PB1176
as well - just one activity led (led 2) goes on and off with
CPU activity.

driver-core: remove sysdev.h usage.

2011-12-22T00:26:03+00:00

The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.

The sysdev code will be going away soon, so this include needs to be
removed no matter what.
