2019-11-11mfd: mfd-core: Move pdev->mfd_cell creation back into mfd_add_device()Lee Jones1-17/+4
Most of the complexity of mfd_platform_add_cell() has been removed. The only functionality left duplicates cell memory into the child's platform device. Since it's only a few lines, moving it to the main thread and removing the superfluous function makes sense.

2019-11-11mfd: mfd-core: Remove usage counting for .{en,dis}able() call-backsLee Jones2-50/+9
The MFD implementation for reference counting was complex and unnecessary. There was only one bona fide user which has now been converted to handle the process in a different way. Any future resource protection, shared enablement functions should be handed by the parent device, rather than through the MFD subsystem API.

2019-11-11mfd: mfd-core: Remove mfd_clone_cell()Lee Jones2-51/+0
Providing a subsystem-level API helper seems over-kill just to save a few lines of C-code. Previous commits saw us convert mfd_clone_cell()'s only user over to use a more traditional style of MFD child-device registration. Now we can remove the superfluous helper from the MFD API.

2019-11-11mfd: mfd-core: Protect against NULL call-back function pointerLee Jones1-0/+10
If a child device calls mfd_cell_{en,dis}able() without an appropriate call-back being set, we are likely to encounter a panic. Avoid this by adding suitable checking.

2019-11-11mfd: cs5535-mfd: Register clients using their own dedicated MFD cell entriesLee Jones1-9/+16
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. Signed-off-by: Lee Jones <lee.jones@linaro.org> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org>
2019-11-11mfd: cs5535-mfd: Request shared IO regions centrallyLee Jones1-41/+33
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.

2019-11-11mfd: cs5535-mfd: Remove mfd_cell->id hackLee Jones1-12/+2
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.

2019-11-11mfd: cs5535-mfd: Use PLATFORM_DEVID_* defines and tidy error messageLee Jones1-2/+3
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.
