Ilya Yanok 74bef9a4fa mxc: add arch_reset() function
This patch adds arch_reset() function for all mxc platforms.

It also removes (unsused) arch/arm/mach-mx2/system.c file.

This patch has been tested on i.MX1/27/31/35

Sascha Hauer 198016e1b1 [ARM] MXC: add cpu_is_ macros
We had hardcoded cpu_is_ macros for mxc architectures till now. As we
want to run the same kernel on i.MX31 and i.MX35 this patch adds cpu_is_
macros which expand to 0 or 1 if only one architecture is compiled in and
only check for the cpu type if more than one architecture is compiled
in.

Sascha Hauer 166091b189 [ARM] MXC: add pwm driver for i.MX SoCs
This driver has been tested on MX27/MX31. It should work on MX1/MX1
aswell, but the actual setting of the PWM is missing so far.

Paulius Zaleckas cfca8b539f patch-mxc-add-ARCH_MX1
Adds MX1 architecture to platform MXC. It will supersede mach-imx
and let it die.

Sascha Hauer 58a85f465f MX2: Add DMA support for mx2 and (eventually) mx1
This patch adds DMA support for Freescale i.MX27 SoCs. It is derived
from the i.MX1 port and should (though currently untested) still be
working for the i.MX1.

Juergen Beisert d0f349fbce i.MXC family: Adding timer support
This patch adds timer support for the i.MX machine family. This code can
be used on the following machs:

 - i.MX1 (tested)
 - i.MX2 (i.MX21 (to be tested), i.MX27 (tested))
 - i.MX3 (i.MX31 (tested))

TODO: It seems impossible to build a kernel for more than one CPU because the
timer do not follow the platform device rules. So it does only work if
timer 1 can be accessed on all CPUs at the same address.

Juergen Beisert 07bd1a6cc7 MXC arch: Add gpio support for the whole platform
This patch bases on the one from Daniel Mack. The most important change to
Daniel's patch is to be more generic. This gpio routine supports at least
the i.MX27 and i.MX31 processors.

Juergen Beisert c0db2ea4e3 MXC family: Add clock handling
Internal clock path handling for the mxc CPUs.

Changed against the original Freescale code (and against clocklib for example):
 - clock rate is always calculated whenever one ask for the current rate
   (means struct clk has no more a member called "rate"). So switching the PLL
   base frequency will propagate immediately to all other clocks that are
   depending on this frequency.

Robert Schwebel 2c130fd529 [ARM] 4877/1: i.MXC family: Clean up current platform code
From: Juergen Beisert <j.beisert@pengutronix.de>

This patch cleans up the in-kernel platform code from doxygen comments.
We don't know how this could have leak in, but anyway.

Changes since last release:
 - none

Quinn Jensen 52c543f90c [ARM] 4461/1: MXC platform and i.MX31ADS core support
This patch adds the foundation pieces for
the Freescale MXC platforms, including
i.MX2 and i.MX3 based systems.

The bare-bones MX31 support in this patch
boots to the rootdev panic with 8250 serial
console configured "console=ttyS0,115200".
It assumes that Redboot is the boot loader.
