[PATCH v2 0/4] phy: core: Add phy bulk helpers support

[Inochi Amaoto]

As discussed in [1], some drivers may do not care the difference between
phys. Instead, they only need to treat them as a group and operate them
together. This means a bulk operation is needed.

Add some bulk helper functions for phy core by referencing the design of
clock/reset subsystem. This can relieve the driver owners' life who needs
to handle many phys, as well as each phy error reporting.
