The DTS file for armada-37xx uses the string "marvell,armada3700-ehci",
but the code searched for "marvell,armada-3700-ehci".

In SGMII initialization PIN_PIPE_SEL has to be zero when resetting
the PHY. Since comphy_mux already set the selector register to
correct values, we have to store it's value before setting it to 0
and restore it after SGMII init.

Lane 0 supports SGMII1 and USB3.
Lane 1 supports SGMII0 and PEX0.
Lane 2 supports SATA0 and USB3.
This is needed for Armada 37xx.
This introduces new device tree bindings. AFAIK there is currently no
driver for Armada 37xx comphy in Linux. When such a driver will be
pushed into Linux, this will need to be rewritten accordingly.

This commit is based on commit d9899826 by
zachary <zhangzg@marvell.com>
from u-boot-marvell, see

- According to design specification, the transmitter should be set to high
impedence mode during electrical idle. Thus transmitter should detect RX
at high impedence mode also, and delay is needed to accommodate high
impedence off latency. Otherwise the USB3 will have detection issue that
most of the time the USB3 device can not be detected at all, or be
detected as USB2 device sometimes.
Modified registers: RD005C302h (R181h) (0051h) Lane Configuration 1
Bit 6: set to 1 to let Tx detect Rx at HiZ mode
Bit [3:4]: set to 2 to be delayed by 2 clock cycles
Bit 0: set to 1 to set transmitter to high impedance mode during idle.
- USB3 De-emphasize level of -3.5dB is mandatory, but USB3 MAC selects 0x2
(emphasize disabled) in the MAC_PHY_TXDEEMPH [1:0], while it is supposed
to select 0x1(3.5dB emphasize). Thus need to override what comes from
the MAC(by setting register 0x1c2 bit2 to 0x1) and to configure the
overridded values of MAC_PHY_TXDEEMPH [1:0] to 0x1(bit15 of register
0x181 and bit0 of register 0x180).
- According to USB3 application note, need to update below comphy
registers:
Set max speed generation to USB3.0 5Gbps(set RD005C04Ah bit[11:10] to 1)
Set capacitor value to 0xF(set RF005C224 bit[3:0] to 0xF)

According to specification, CFG_PM_RXDLOZ_WAIT should be set to 0x7
when reference clock is at 25 MHz. The specification (at least the
version I have) does not mentoin the setting for 40 MHz reference
clock, but Marvell's U-Boot sets 0xC in that case.

When USB3 is on comphy lane 2 on the Armada 37xx, the registers
have to be accessed indirectly via SATA indirect access.
This is the case of the Turris Mox board from CZ.NIC.

Currently there is for each register special functional macro, ie:
LANE_CFG1_ADDR(u)
GLOB_CLK_SRC_LO_ADDR(u)
...
where can be either PCIE or USB3.
Change this to one function PHY_ADDR(unit, addr). The code becomes:

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
