Gustavo A. R. Silva 31e1c59796 drm/ttm: use swap macro in ttm_bo_handle_move_mem
Make use of the swap macro and remove unnecessary variable *tmp_mem*.
This makes the code easier to read and maintain. Also, reduces the
stack usage.

This code was detected with the help of Coccinelle.

Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.

Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".

Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.

Jan Tuerk aa7e6455e1 drm/panel: Add support for the EDT ETM0700G0BDH6
The Emerging Display Technology ETM0700G0BDH6 is exactly
the same display as the ETM0700G0DH6, exept the pixelclock
polarity. Therefore re-use the ETM0700G0DH6 modes. It is
used by default on emtrion Avari based development kits.

Noralf Trønnes 894a677f4b drm/cma-helper: Use the generic fbdev emulation
This switches the CMA helper drivers that use its fbdev emulation over
to the generic fbdev emulation. It's the first phase of using generic
fbdev. A later phase will use DRM client callbacks for the
lastclose/hotplug/remove callbacks.

There are currently 2 fbdev init/fini functions:
- drm_fb_cma_fbdev_init/drm_fb_cma_fbdev_fini
- drm_fbdev_cma_init/drm_fbdev_cma_fini

This is because the work on generic fbdev came up during a fbdev
refactoring and thus wasn't completed. No point in completing that
refactoring when drivers will soon move to drm_fb_helper_generic_probe().

tinydrm uses drm_fb_cma_fbdev_init_with_funcs().
