mfd: cs5535-mfd: Register clients using their own dedicated MFD cell entries

2019-11-11T08:45:03+00:00

CS5535 is the only user of mfd_clone_cell().  It makes more sense to
register child devices in the traditional way and remove the quite
bespoke mfd_clone_cell() call from the MFD API.

mfd: cs5535-mfd: Request shared IO regions centrally

2019-11-11T08:45:03+00:00

Prior to this patch, IO regions were requested via an MFD subsytem-level
.enable() call-back and similarly released by a .disable() call-back.
Double requests/releases were avoided by a centrally handled usage count
mechanism.

This complexity can all be avoided by handling IO regions only once during
.probe() and .remove() of the parent device.  Since this is the only
legitimate user of the aforementioned usage count mechanism, this patch
will allow it to be removed from MFD core in subsequent steps.

mfd: cs5535-mfd: Remove mfd_cell->id hack

2019-11-11T08:45:03+00:00

The current implementation abuses the platform 'id' mfd_cell member
to index into the correct resources entry.  Seeing as enough resource
slots are already available, let's just loop through all available
bars and allocate them to their appropriate slot, even if they happen
to be zero.

mfd: cs5535-mfd: Use PLATFORM_DEVID_* defines and tidy error message

2019-11-11T08:45:03+00:00

In most contexts '-1' doesn't really mean much to the casual observer.
In almost all cases, it's better to use a human readable define.  In
this case PLATFORM_DEVID_* defines have already been provided for this
purpose.

While we're here, let's be specific about the 'MFD devices' which
failed.  It will help when trying to distinguish which of the 2 sets
of sub-devices we actually failed to register.

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
