Subject: [PATCH] net: phy: Add BIT macro for Motorcomm yt8521/yt8531 gigabit
ethernet phy
Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy.
This is a preparatory patch. Add BIT macro for 0xA012 reg, and
supplement for 0xA001 and 0xA003 reg. These will be used to support dts.

Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8521 gigabit
ethernet phy
Add dts support for Motorcomm yt8521 gigabit ethernet phy.
Add ytphy_rgmii_clk_delay_config function to support dst config for
the delay of rgmii clk. This funciont is common for yt8521, yt8531s
and yt8531.
This patch has been verified on AM335x platform.

Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8531s gigabit
ethernet phy
Add dts support for Motorcomm yt8531s gigabit ethernet phy.
Change yt8521_probe to support clk config of yt8531s. Becase
yt8521_probe does the things which yt8531s is needed, so
removed yt8531s function.
This patch has been verified on AM335x platform with yt8531s board.

Subject: [PATCH] net: phy: Add driver for Motorcomm yt8531 gigabit ethernet
phy
Add a driver for the motorcomm yt8531 gigabit ethernet phy. We have
verified the driver on AM335x platform with yt8531 board. On the
board, yt8531 gigabit ethernet phy works in utp mode, RGMII
interface, supports 1000M/100M/10M speeds, and wol(magic package).

Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy.
This is a preparatory patch. Add BIT macro for 0xA012 reg, and
supplement for 0xA001 and 0xA003 reg. These will be used to support dts.

Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8521 gigabit
ethernet phy
Add dts support for Motorcomm yt8521 gigabit ethernet phy.
Add ytphy_rgmii_clk_delay_config function to support dst config for
the delay of rgmii clk. This funciont is common for yt8521, yt8531s
and yt8531.
This patch has been verified on AM335x platform.

Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8531s gigabit
ethernet phy
Add dts support for Motorcomm yt8531s gigabit ethernet phy.
Change yt8521_probe to support clk config of yt8531s. Becase
yt8521_probe does the things which yt8531s is needed, so
removed yt8531s function.
This patch has been verified on AM335x platform with yt8531s board.

phy
Add a driver for the motorcomm yt8531 gigabit ethernet phy. We have
verified the driver on AM335x platform with yt8531 board. On the
board, yt8531 gigabit ethernet phy works in utp mode, RGMII
interface, supports 1000M/100M/10M speeds, and wol(magic package).

Subject: [PATCH] net: phy: Add driver for Motorcomm yt8531 gigabit ethernet phy
Add a driver for the motorcomm yt8531 gigabit ethernet phy. We have
verified the patch on AM335x platform which has one YT8531 interface
card and passed all test cases. The tested cases indluding: YT8531 UTP
function with support of 10M/100M/1000M and wol(based on magic packet).
