ISEE IGEPv2 is an TI OMAP3 SoC based embedded board.

This patch adds an initial device tree support to boot
an IGEPv2 from the MMC/SD.

Currently is working everything that is supported by DT
on OMAP3 SoCs (MMC/SD, GPIO LEDs, EEPROM, TWL4030 audio).

omap3_noncore_dpll_set_rate() attempts an enable of bypass clk as well
as ref clk for every .set_rate attempt on a noncore DPLL, regardless of
whether the .set_rate results in the DPLL being locked or put in bypass.
Early at boot, while some of these DPLLs are programmed and locked
(using .set_rate for the DPLL), this causes an ordering issue.

For instance, on OMAP5, the USB DPLL derives its bypass clk from ABE DPLL.
If a .set_rate of USB DPLL which programmes the M,N and locks it is called
before the one for ABE, the enable of USB bypass clk (derived from ABE DPLL)
then attempts to lock the ABE DPLL and fails as the M,N values for ABE
are yet to be programmed.

To get rid of this ordering needs, enable bypass clk for a DPLL as part
of its .set_rate only when its being put in bypass, and only enable the
ref clk when its locked.

WDT1 module can take one of the below clocks as input functional
clock -
     - On-Chip 32K RC Osc [default/reset]
     - 32K from PRCM

The On-Chip 32K RC Osc clock is not an accurate clock-source as per
the design/spec, so as a result, for example, timer which supposed
to get expired @60Sec, but will expire somewhere ~@40Sec, which is
not expected by any use-case.

The solution here is to switch the input clock-source to PRCM
generated 32K clock-source during boot-time itself.

Pull ceph fix from Sage Weil:
 "This fixes a regression introduced during the last merge window when
  mapping non-existent images."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  rbd: don't zero-fill non-image object requests

A result of ENOENT from a read request for an object that's part of
an rbd image indicates that there is a hole in that portion of the
image.  Similarly, a short read for such an object indicates that
the remainder of the read should be interpreted a full read with
zeros filling out the end of the request.

This behavior is not correct for objects that are not backing rbd
image data.  Currently rbd_img_obj_request_callback() assumes it
should be done for all objects.

Change rbd_img_obj_request_callback() so it only does this zeroing
for image objects.  Encapsulate that special handling in its own
function.  Add an assertion that the image object request is a bio
request, since we assume that (and we currently don't support any
other types).

This resolves a problem identified here:
    http://tracker.ceph.com/issues/4559

The regression was introduced by bf0d5f50.
