Axel Lin 018e6ff3c0 phy: miphy28lp: Convert to devm_kcalloc and fix wrong sizof
Prefer devm_kcalloc over devm_kzalloc with multiply.
In additional, use sizeof(phy) is incorrect, fix it.

Axel Lin 21647f7383 phy: miphy28lp: Avoid calling of_get_child_count() multiple times
Currently, of_get_child_count() is called in each iteration of the for loop in
miphy28lp_xlate(). This patch stores the return value of of_get_child_count()
in miphy_dev->nphys and call of_get_child_count() once in miphy28lp_probe().

Gabriel FERNANDEZ de6e0f84be phy: miphy28lp: Pass sysconfig register offsets via syscfg dt property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy28lp phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces like
it does currently for miphy28lp. This change then also aligns us to how other
platforms such as keystone and bcm7445 pass there syscon offsets via DT.

I have updated the miphy28lp phy driver same way as Peter's implementation.

Gabriel FERNANDEZ a2108dee3c phy: miphy28lp: Add SSC support for PCIE
SSC is the technique of modulating the operating frequency of a signal
slightly to spread its radiated emissions over a range of frequencies.
This reduction in the maximum emission for a given frequency helps meet
radiated emission requirements.
These settings are applicable for PCIE with Internal clock.
