Subject: [PATCH 5.11 219/254] net: phy: broadcom: Fix RGMII delays for BCM50160 and BCM50610M

From: Florian Fainelli <f.fainelli@...il.com>

[ Upstream commit b1dd9bf688b0dcc5a34dca660de46c7570bd9243 ]

The PHY driver entry for BCM50160 and BCM50610M calls
bcm54xx_config_init() but does not call bcm54xx_config_clock_delay() in
order to configuration appropriate clock delays on the PHY, fix that.

Fixes: 733336262b28 ("net: phy: Allow BCM5481x PHYs to setup internal TX/RX clock delay")
