This adds a weak definition of comphy_update_map to comphy_core,
which does nothing. If this function is defined elsewhere, for example
in board file, the board file can change some parameters of SERDES
configuration.
This is needed on Turris Mox, where the SERDES speed on lane 1 has to
be set differently when SFP module is connected and when Topaz Switch
module is connected.
This is a temporary solution. When the comphy driver for armada-3720
will be added to the kernel, the comphy driver in u-boot shall also be
updated and this should be done differently then.

On newer Allwinner SoC, there is a pair of EHCI/OHCI USB hosts
for OTG host mode. USB PHY passby must be configured for its
corresponding PHY. so we can call for PHY#0. on the other hand
in past usb-phy code the same thing can be restricted for
Lower SoC's, other than H3/H5/A64.
Now there is no need to restrict usb passby since the phy driver
is DT enabled, and the respective phy calls will trigger based
DT information initiated by the drivers.

In case of phy are provided from a PHY provider nodes as following:

#address-cells = <1>;
#size-cells = <0>;
usbphyc_port0: usb-phy@0 {
reg = <0>;
phy-supply = <&vdd_usb>;
vdda1v1-supply = <®11>;
vdda1v8-supply = <®18>
#phy-cells = <0>;
};
usbphyc_port1: usb-phy@1 {

phy-supply = <&vdd_usb>;
vdda1v1-supply = <®11>;
vdda1v8-supply = <®18>
#phy-cells = <1>;
};
};
and PHY are called as following:
usbh_ehci: usbh-ehci@5800d000 {
compatible = "generic-ehci";
reg = <0x5800d000 0x1000>;
clocks = <&rcc_clk USBH>;
resets = <&rcc_rst USBH_R>;
interrupts = <GIC_SPI 75 IRQ_TYPE_NONE>;
companion = <&usbh_ohci>;
phys = <&usbphyc_port0>;
phy-names = "usb";
status = "okay";
};
generic_phy_get_by_index() must be updated to first look for
PHY phandle as previously and in case of error looks for PHY
provider by finding the parent's current node which is the PHY
provider.
args (ofnode_phandle_args struct) must also be updated by inserting
the phy index into the PHY provider as args[0].

The sunxi otg phy has a bug where it wrongly detects a high speed squelch
when reset on the root port gets de-asserted with a lo-speed device.
The workaround for this is to disable squelch detect before de-asserting
reset, and re-enabling it after the reset de-assert is done. Add a sunxi
specific phy function to allow the sunxi-musb glue to do this.

Current implementation is unable to get pinctrl, clock and reset

Lane 1 supports SGMII0 and PEX0.
Lane 2 supports SATA0 and USB3.
This is needed for Armada 37xx.

pushed into Linux, this will need to be rewritten accordingly.

Add support for nontrivial order, with map stored in device tree

As far as I know, there is no driver for Armada 37xx comphy in the

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

Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members. There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".
As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.
Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

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.
