-Subject: [PATCH] net: phy: realtek: add dt property to disable CLKOUT clock
-
-CLKOUT is enabled by default after PHY hardware reset, this patch adds
-"realtek,clkout-disable" property for user to disable CLKOUT clock
-to save PHY power.
-
-Per RTL8211F guide, a PHY reset should be issued after setting these
-bits in PHYCR2 register. After this patch, CLKOUT clock output to be
-disabled.
