IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively. However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers. This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:
* testing efforts are divided between two subsystems
* having duplicate drivers for same hardware confuses users
This patch converts ppc6xx_defconfig to use libata PATA

Returning a negative value for a boolean function seem to have the
undesired effect of returning true. require_paranoia_below() is a
boolean function, but the variable used to store the return value is an
integer, receiving -1 or 0. This patch converts rc to bool, replaces -1
by false, and 0 by true.
mpe: This wasn't exhibiting in practice because the common case, where
we do the comparison of the desired level vs the current value, was
being compiled into a computation based on the result of the comparison,
ie. it wasn't using the default -1 value at all. However that was just
luck and the code is still wrong.

Some SoCs (for example Amlogic GXBB) implement a reset controller which
only supports a reset pulse (triggered via reset_control_reset). At the
same time multiple devices (in case of the Amlogic GXBB SoC both USB
PHYs) are sharing the same reset line.
This patch allows using reset_control_reset also for shared resets.
There are limitations though:
reset_control_reset can only be used if reset_control_assert was not
used yet.
reset_control_assert can only be used if reset_control_reset was not
used yet.
For shared resets the reset is only triggered once for the lifetime of
the reset_control instance (the reset can be triggered again if all
consumers of that specific reset_control are gone, as the reset
framework will free the reset_control instance in that case).

On i.MX6QP the LDB clock tree has changed to move the clk gate
before the divider, to prevent clock glitches propagating downstream.
A consequence of this change is that the clk divider is now the
parent of the LDB inputs. Reflect this change in the devicetree
to allow the LDB driver to properly configure the display clocks.

Now the struct psbfb_ops implements two additional members:

.fb_pan_display = drm_fb_helper_pan_display,
and the struct psbfb_roll_ops implements one additional member:
.fb_setcmap = drm_fb_helper_setcmap,
and the struct psbfb_unaccel_ops implements two additional members:
.fb_setcmap = drm_fb_helper_setcmap,

A drm driver that is implementing
fb_debug_enter and fb_debug_leave
in struct fb_ops with drm fb helper functions
drm_fb_helper_debug_enter and drm_fb_helper_debug_leave
must also implement the callback 'mode_set_base_atomic' in struct
drm_crtc_helper_funcs. See Documentation/DocBook/kgdb.tmpl. The current
implementation will segfault when 'mode_set_base_atomic' is a NULL
pointer.
Before this patch at least the drm drivers armada, ast, qxl, udl and
virtio do not have a 'mode_set_base_atomic' implementation but using
drm_fb_helper_debug_(enter|leave). So these drivers may segfault when
callbacks fb_debug_(enter|leave) are called.
Avoid the issue by just checking for NULL pointers. So all drivers can
unconditionally implement fb_debug_(enter|leave) with the drm_fb_helper
functions. If callback 'mode_set_base_atomic' is not implemented, the
code in drm_fb_helper_debug_(enter|leave) does effectively nothing.
