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

On some ARM based systems, a separate Cortex-M based System Control
Processor(SCP) provides the overall power, clock, reset and system
control. System Control and Management Interface(SCMI) Message Protocol
is defined for the communication between the Application Cores(AP)
and the SCP.
Adds support for the resets provided using SCMI protocol for performing
reset management of various devices present on the SoC. Various reset
functionalities are achieved by the means of different ARM SCMI device
operations provided by the ARM SCMI framework.

Some of the mipi dsi resets were called

Since they're DSI related this looks like a typo. This fixes the

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.
