[PATCH v2 0/3] net: mdio: mdio-thunder: MDIO clock related changes for Marvell Octeon Family.

[Piyush Malgujar <pmalgujar@marvell.com>]

This patch series mdio changes are pertaining to Marvell Octeon family.

1) clock gating:
	The purpose of this change is to apply clock gating for MDIO clock
	when there is no transaction happening. This will stop the MDC
	clock toggling in idle scenario.

2) Marvell MDIO clock frequency attribute change:
	This MDIO change provides an option for user to have the bus speed
	set to their needs. The clock-freq for Marvell Octeon defaults to
	3.125 MHz and not 2.5 MHz as standard. In case someone needs to use
	this attribute, they have to add an extra attribute
	"clock-frequency" in the mdio entry in their DTS and this driver
	will do the rest.
        The changes are made in a way that the clock will set to the
	nearest possible value based on the clock calculation and required
	frequency from DTS.
        
These changes has been verified internally with Marvell Octeon series.

Changes since V1:
* Separated the logical changes in separate patches
* Replaced macros with functions
* Used proper property name for DTS
* Updated DTS binding
