There is no in-tree mxsfb users using mxsfb_platform_data dotclk_delay.
Let's remove it from mxsfb_platform_data to ease full device tree

There is no in-tree users of mxsfb_platform_data fb_phys/fb_size.
With CMA support in the kernel, there is no real need for platform to
reserve memory and pass address and size into driver via platform_data.
So let's remove fb_phys/fb_size from mxsfb_platform_data to ease full

When the optional clk_ptp is absent, we can just set it to NULL, and
clk API will just handle it gracefully. It saves us from checking
clk_ptp whenever calling into clk API.
Also since clk_ptp is optional, the "ret" variable shouldn't be set
in case that the clock is absent.

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
