omap4_ctrl_pad_readl/writel are no longer used by anybody, so remove
these. Syscon / pinctrl should be used to access the padconf area
instead.

<title>ARM: OMAP2+: control: determine control module base address from DT</title>

There is no need to provide the control module base address through a
low-level API from the low-level IO init, as this information is
available through DT. This patch adds a new API to initialize the
control module though, but mostly makes the old API obsolete. The
old API can be completely removed once OMAP3 is made DT only.

Pull ARM SoC non-critical fixes from Olof Johansson:
 "Here's a small collection of fixes accrued during the last release
  that weren't considered severe enough to merge during the -rc series.

  A few of these are around resurrecting TI81xx support that's been
  broken for quite a while, the rest are smaller fixes -- most for PXA
  but a few across the board.

  There are also some updates to MAINTAINERS here, in particular for
  Broadcom platforms"

Otherwise we get error "Cannot detect omap type!" and many
things can fail with following:

Unhandled fault: imprecise external abort (0xc06) at 0xc6031fb0

This is because the omap_type is being used to set up th SoC
specific functions for omaps.

<title>ARM: dra7xx: Fix counter frequency drift for AM572x errata i856</title>

<content type='text'>
Errata i856 for the AM572x (DRA7xx) points out that the 32.768KHz external
crystal is not enabled at power up.  Instead the CPU falls back to using
an emulation for the 32KHz clock which is SYSCLK1/610.  SYSCLK1 is usually
20MHz on boards so far (which gives an emulated frequency of 32.786KHz),
but can also be 19.2 or 27MHz which result in much larger drift.

Since this is used to drive the master counter at 32.768KHz * 375 /
2 = 6.144MHz, the emulated speed for 20MHz is of by 570ppm, or about 43
seconds per day, and more than the 500ppm NTP is able to tolerate.

Checking the CTRL_CORE_BOOTSTRAP register can determine if the CPU
is using the real 32.768KHz crystal or the emulated SYSCLK1/610, and
by known that the real counter frequency can be determined and used.
The real speed is then SYSCLK1 / 610 * 375 / 2 or SYSCLK1 * 75 / 244.

The mach-omap2 directory contains full register defines for OMAP4
control module but only around 27 of those are used. There are is
a total of 1795 register defines in four files with only 27 in use.
That is pretty low usefulness ratio...

I guess alot more was used when we had omap4 board files and
mach-omap2 contained more drivers but this has now changed.
