123ca114e0 net: introduce helpers to get PHY interface mode from a device/ofnode
Add helpers ofnode_read_phy_mode() and dev_read_phy_mode() to parse the
"phy-mode" / "phy-connection-type" property. Add corresponding UT test.

Use them treewide.

This allows us to inline the phy_get_interface_by_name() into
ofnode_read_phy_mode(), since the former is not used anymore.

5faf161d07 net: phy: atheros: avoid error in ar803x_of_init() when PHY has no OF node
A DM_ETH driver may use phy_connect() towards a PHY address on an MDIO
bus which is not specified in the device tree, as evidenced by:

pfe_eth_probe
-> pfe_phy_configure
   -> phy_connect

When this happens, the PHY will have an invalid OF node.

When ar803x_config() runs, it silently fails at ar803x_of_init(), and
therefore, fails to run the rest of the initialization.

This makes MII_BMCR contain what it had after BMCR_RESET (0x8000) has
been written into it by phy_reset(). Since BMCR_RESET is volatile and
self-clearing, the MII_BMCR ends up having a value of 0x0. The further
configuration of this register, which is supposed to be handled by
genphy_config_aneg() lower in ar803x_config(), never gets a chance to
run due to this early error from ar803x_of_init().

As a result of having MII_BMCR as 0, the following symptom appears:

=> setenv ethact pfe_eth0
=> setenv ipaddr 10.0.0.1
=> ping 10.0.0.2
pfe_eth0 Waiting for PHY auto negotiation to complete......... TIMEOUT !
Could not initialize PHY pfe_eth0

Manually writing 0x1140 into register 0 of the PHY makes the connection
work, but it is rather desirable that the port works without any manual
intervention.

pfe_eth_probe

When this happens, the PHY will have an invalid OF node.

The dp83867_config() method has extra initialization steps which are
bypassed when the PHY lacks an OF node, which is undesirable because it
will lead to broken networking. Allow the rest of the code to run.

4de720e98d Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.

The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).

f861ce90ca ram: k3-ddrss: Introduce ECC Functionality for full memory space
Introduce ECC Functionality for full memory space as implemented in the
DDRSS. The following is done to accomplish this:

 * Introduce a memory region "ss" to allow dt to provide DDRSS region,
   which is not the same as "ctl" which is the controller region.

 * Introduce a "ti,ecc-enable" flag which allows a memorycontroller
   instance to enable ecc.

 * Introduce functionality to properly program the DDRSS registers to
   enable ECC for the full DDR memory space if enabled with above flag.

 * Expose a k3_ddrss_ddr_fdt_fixup call to allow fixup of fdt blob to
   account from DDR memory that must be reserved for ECC operation.

71eb527476 ram: k3-ddrss: Rename ddrss_ss_regs to ddrss_ctl_regs
The current address being read from dt actually represents the ddrss_ctl
memory region, while ddrss_ss region is something else. Introduce
ddrss_ctl_regs and use it to free up ddrss_ss_regs for its proper
purpose later so that we can avoid confusion.
