Daniel Lezcano ac03fec1d7 mfd: hi655x: Add the clock cell to provide WiFi and Bluetooth
The hi655x is a PMIC with regulator but also provides a clock for the WiFi
and the bluetooth which is missing in the current implementation.

Add the clock cell so it can be used in the next patch via the dts.

Javier Martinez Canillas e45b6c80b8 mfd: hi655x-pmic: Fix module autoload when registered via OF
If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/mfd/hi655x-pmic.ko | grep alias

After this patch:

$ modinfo drivers/mfd/hi655x-pmic.ko | grep alias
alias:          of:N*T*Chisilicon,hi655x-pmicC*
alias:          of:N*T*Chisilicon,hi655x-pmic

Wei Yongjun 7e28abda8c mfd: hi655x: Fix return value check in hi655x_pmic_probe()
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR(). Also remove unneeded error handling of
platform_get_resource().

John Stultz 9e3d5c996b mfd: hi655x-pmic: Rename some interrupt macro names
Currently the hi655x-pmic driver has names for interrupt mask
values, but not for the interrupt numbers themselves.

So to allow for interrupt numbers to have sane names, rename
the mask values with the _MASK postfix and use the existing
names as the interrupt name

John Stultz 417e06bb3f mfd: hi655x-pmic: Fixup issue with un-acked interrupts
While trying to get the powerkey to function, I found when
pressing the key, I would get infinitely repeating interrupts.

After digging around a bit, it seems we didn't set the ack_base
value for the regmap irqchip logic, so nothing was acking the
interrupt.

This patch adds the ack_base, which seems to make things work.
