net: dsa: microchip: add the support for set_ageing_time

KSZ9477 has the 11 bit ageing count value which is split across the two
registers. And LAN937x has the 20 bit ageing count which is also split
into two registers. Each count in the registers represents 1 second.
This patch add the support for ageing time for KSZ9477 and LAN937x
series of switch.

====================
net: dsa: microchip: add support for phylink mac config and link up

This patch series add support common phylink mac config and link up for the ksz
series switches. At present, ksz8795 and ksz9477 doesn't implement the phylink
mac config and link up. It configures the mac interface in the port setup hook.
ksz8830 series switch does not mac link configuration. For lan937x switches, in
the part support patch series has support only for MII and RMII configuration.
Some group of switches have some register address and bit fields common and
others are different. So, this patch aims to have common phylink implementation
which configures the register based on the chip id.

Changes in v2
- combined the modification of duplex, tx_pause and rx_pause into single
function.

Changes in v1
- Squash the reading rgmii value from dt to patch which apply the rgmii value
- Created the new function ksz_port_set_xmii_speed
- Seperated the namespace values for xmii_ctrl_0 and xmii_ctrl_1 register
- Applied the rgmii delay value based on the rx/tx-internal-delay-ps

net: dsa: microchip: add common ksz port xmii speed selection function

This patch adds the function for configuring the 100/10Mbps speed
selection for the ksz switches. KSZ8795 switch uses Global control 4
register 0x06 bit 4 for choosing 100/10Mpbs. Other switches uses xMII
control 1 0xN300 for it.
For KSZ8795, if the bit is set then 10Mbps is chosen and if bit is
clear then 100Mbps chosen. For all other switches it is other way
around, if the bit is set then 100Mbps is chosen.
So, this patch add the generic function for ksz switch to select the
100/10Mbps speed selection. While configuring, first it disables the
gigabit functionality and then configure the respective speed.

net: dsa: microchip: add common gigabit set and get function

This patch add helper function for setting and getting the gigabit
enable for the ksz series switch. KSZ8795 switch has different register
address compared to all other ksz switches. KSZ8795 series uses the Port
5 Interface control 6 Bit 6 for configuring the 1Gbps or 100/10Mbps
speed selection. All other switches uses the xMII control 1 0xN301
register Bit6 for gigabit.
Further, for KSZ8795 & KSZ9893 switches if bit 1 then 1Gbps is chosen
and if bit 0 then 100/10Mbps is chosen. It is other way around for
other switches bit 0 is for 1Gbps. So, this patch implements the common
function for configuring the gigabit set and get capability.

====================
net: dsa: microchip: DSA Driver support for LAN937x

LAN937x is a Multi-Port 100BASE-T1 Ethernet Physical Layer switch
compliant with the IEEE 802.3bw-2015 specification. The device provides
100 Mbit/s transmit and receive capability over a single Unshielded
Twisted Pair (UTP) cable. LAN937x is successive revision of KSZ series
switch.
This series of patches provide the DSA driver support for
Microchip LAN937X switch through MII/RMII interface. The RGMII interface

operation and 0 - write operation. But for lan937x bit 1:0 used for
selecting the read/write operation, 01 - write and 10 - read.
To use ksz9477 mdb add/del and enable_stp_addr for the lan937x, masks &
shifts are introduced for ksz9477 & lan937x in ksz_common.c. Then
updated the function with masks & shifts based on the switch instead of
hard coding it.

Merge branch 'dsa-microchip-ksz_chip_reg'

Arun Ramadoss says:

====================
net: dsa: microchip: use ksz_chip_reg for

This patch series tries to use the same approach as struct ksz8 for
register which has different address for different switch family. It
moves the struct ksz8 from ksz8.h to struct ksz_chip_reg. Based on the
switch detect, the corresponding mask, reg and shifts are assigned.
