Reset controller updates for v5.6
This tag adds support for the Nuvoton NPCM, Intel Gatway SoC, and
Broadcom BCM7216 RESCAL reset controllers, adds missing SCSSI reset
controls for newer Uniphier SoCs, aligns the program flow in the
devm_reset_controller_register, __devm_reset_control_get, and
devm_reset_control_array_get functions for better consistency,
and allows to build the Qcom AOSS reset driver as a module.This is based on v5.5-rc3 because the core patch depends on commit
db23808615e2 ("reset: Do not register resource data for missing
resets").* tag 'reset-for-5.6' of git://git.pengutronix.de/pza/linux:

…ux-pm into arm/drivers
Initial support for hierarchical CPU arrangement, managed by PSCI and its
corresponding cpuidle driver. This support is based upon using the generic
PM domain, which already supports devices belonging to CPUs.Finally, these is a DTS patch that enables the hierarchical topology to be
used for the Qcom 410c Dragonboard, which supports the PSCI OS-initiated
mode.* tag 'cpuidle_psci-v5.5-rc4' of git://git.linaro.org/people/ulf.hansson/linux-pm: (611 commits)

The use of IS_ALIGNED() is incorrect, the typical resource we pass looks
like this: start: 0x8404318, size: 0x30. When using IS_ALIGNED() we will
get the following 0x8404318 & (0x18 - 1) = 0x10 which is definitively
not equal to 0, same goes with the size. These two checks would make the
driver fail probing.Remove the resource checks, since there should be no constraint on the
base addresse or size.Fixes: 77750bc089e4 ("reset: Add Broadcom STB SW_INIT reset controller driver")

Pointer dev is being dereferenced when passed to the inlined
functon dev_name, however, dev is later being null checked
so at first this seems like a potential null pointer dereference.In fact, _reset_control_get_from_lookup is only ever called from
__reset_control_get, right after checking dev->of_node hence
dev can never be null. Clean this up by removing the redundant
null check.Thanks to Philipp Zabel for spotting that dev can never be null.
