843e8a47e2 realtek: rtl930x: Disable L3 offloading
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
L3 Offloading caused DHCP packets to be dropped at hardware level
And potentially buggy route implementation can cause a crash

b49f9d9804 realtek: backport ECC driver
Upstream will get support for the Realtek ECC engine with 6.18.
To make use of this in Openwrt

- backport upstream patches
- change config so that ECC will be built for nand subtargets
- define ECC engine in RTL93xx DTS.

fe27cce1ec realtek: add SerDes PCS driver
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Build all core packages / Build all core packages for selected target (push) Waiting to run
Until now the the SerDes configuration is realized with helper functions
scattered around the DSA and PHY driver. Give them a new home as a PCS
driver.

The target design is as follows:

- dsa driver manages switch
- pcs driver manages SerDes on high level (this commit)
- mdio driver manages SerDes on low level

This driver adds the high level SerDes access via PCS. It makes use of
the low level mdio SerDes driver to access the registers.

Remark: This initial version provides exactly all phylink_pcs_ops that
are currently part of the DSA driver. So this can be swapped in one of
the next commits as a drop in replacement. To make use of it something
like this is needed:

...
ports = of_get_child_by_name(node, "ethernet-ports");
if (!ports)
	return -EINVAL;

for_each_available_child_of_node(ports, port) {
	pcs_node = of_parse_phandle(port, "pcs-handle", 0);
	of_property_read_u32(port, "reg", &port_nr)) {

	priv->pcs[port_nr] = rtpcs_create(dev, pcs_node, port_nr);
}
...

7a7ee72c4d realtek: mdio: add SerDes driver
Until now the SerDes access is realized with some helper functions
in the mdio bus. These were moved around a lot and had no real home.
End that temporary solution to move them where they belong.

The target design for the different Realtek drivers is as follows:

- dsa driver manages switch
- pcs driver manages SerDes on high level (to be developed)
- mdio driver manages SerDes on low level (this commit)

This driver adds the low level SerDes access via mdio. For debugging
purposes the user can interact with the SerDes in different ways.

First, there is a debug interface in
/sys/kernel/debug/realtek_otto_serdes/serdes.X/registers.
With that a dump of all registers can be shown.

> cat /sys/kernel/debug/realtek_otto_serdes/serdes.4/registers
Back SDS  4:   00   01   02   03   04   05   06   07   08
SDS        : 0C03 0F00 7060 7106 074D 0EBF 0F0F 0359 5248
SDS_EXT    : 0000 0000 85FA 8C6D 5CCC 0000 20D8 0003 79AA
...

Second, one can read/write registers via the mmd functions of the
mdio command line tool. Important to know: The registers are accessed
on the vendor specific MDIO_MMD_VEND1 device address (=30). Additionally
the SerDes page and register are concatenated into the the mmd register.
Top 8 bits are SerDes page and bottom 8 bits are SerDEs register.
E.g.

- mmd 0x0206 : SerDes page 0x02, SerDes register 0x06
- mmd 0x041f : SerDes page 0x04, SerDes register 0x1f

Read register 0x02 on page 0x03 of SerDes 0
> mdio realtek-serdes-mdio mmd 0:30 raw 0x0302

Write register 0x12 on page 0x02 of SerDes 1
> mdio realtek-serdes-mdio mmd 1:30 raw 0x0212 0x2222

For now this driver is only defined in the devicetree and activated
in the kernel build. There is no current consumer but at least
the debugging interface is available. Cleanup of the currently used
SerDes functions will come later.

fcd3ce6954 realtek: carve out mdio bus from ethernet driver
So much code was distributed between phy/ethernet/dsa drivers. A lot
was already cleand up before. With this step the mdio bus gets its
own space and is no longer hidden inside the ethernet driver.

This commit is mostly a copy/paste that includes only minor changes.

- define prefixes are renamed to RTMDIO
- The driver is totally self contained (does not rely on SoC include)
- The DTS structure (mdio node below ethernet node) was kept
- The driver is added to the kernel config of all subtargets.

41b0340ff0 realtek: backport NAND driver for RTL93xx
RTL93xx devices have a NAND controller built in. Upstream already
has a driver in place. Include it downstream. Activate it in the
RTL93xx builds and disable it for the RTL83xx builds.
