5cb2828092 realtek: Use new CEVT timer
Selects the new CEVT timer for Realtek instead of the previous
timer driver. While we are at it, we explicitily state we do
not use the I2C driver of the RTL9300.

775d903216 realtek: Replace the RTL9300 generic timer with a CEVT timer
The RTL9300 has a broken R4K MIPS timer interrupt, however, the
R4K clocksource works. We replace the RTL9300 timer with a
Clock Event Timer (CEVT), which is VSMP aware and can be instantiated
as part of brining a VSMTP cpu up instead of the R4K CEVT source.
For this we place the RTL9300 CEVT timer in arch/mips/kernel
together with other MIPS CEVT timers, initialize the SoC IRQs
from a modified smp-mt.c and instantiate each timer as part
of the MIPS time setup in arch/mips/include/asm/time.h instead
of the R4K CEVT, similarly as is done by other MIPS CEVT timers.

47f5a0a3ee realtek: Add support for ZyXEL GS1900-48 Switch
The GS1900-48 is a 48 + 2 port Gigabit L2 switch with 48 gigabit ports.
Hardware:
    RTL8393M SoC
    Macronix MX25l12805D (16MB flash)
    128MB RAM
    6 * RTL8218B external PHY
    2 * RTL8231 GPIO extenders to control the port LEDs, system LED and
    Reset button

2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules.

Power is supplied via a 230 volt mains connector.
The board has a hard reset switch SW1, which is is not reachable from the outside.
J4 provides a 12V RS232 serial connector which is connected through U8 to
the 3.3V UART of the RTL8393. Conversion is done by U8, a SIPEX 3232EC.
To connect to the UART, wires can be soldered to R603 (TX)  and R602 (RX).

Installation:
Install the squashfs image via Realtek's original Web-Interface.

45053b507c realtek: Add support for SFP EEPROM-access over SMBus
The EEPROMs on SFP modules are compatible both to I2C as well
as SMBus. However, the kernel so far only supports I2C
access. We add SMBus access routines, because the I2C driver
for the RTL9300 HW only supports that protocol. At the same
time we disable I2C access to PHYs on SFP modules as otherwise
detection of any SFP module would fail. This is not in any
way problematic at this point in time since the RTL93XX
platform so far does not support PHYs on SFP modules.

f4bdb7fdcc realtek: Add support for RTL9300/RTL9310 I2C multiplexing
The RTL9300/RTL9310 I2C controllers have support for 2 independent I2C
masters, each with a fixed SCL pin, that cannot be changed. Each of these
masters can use 8 (RTL9300) or 16 (RTL9310) different pins for SDA.
This multiplexer directly controls the two masters and their shared
IO configuration registers to allow multiplexing between any of these
busses. The two masters cannot be used in parallel as the multiplex
is protected by a standard multiplex lock.

9e7149f729 realtek: revert to "standard" management configuration
The default management interface should be easy to find for users
doing "blind" installations without console access.  There are
already multiple examples in the forum of advanced early adopters
having problems locating the management interface after installing
OpenWrt.

Requiring tagged VLAN configration to access the initial management
interface creates unnecessary hassle at best. Errors on the other
end are close to impossible to debug without console access, even
for advanced users.  Less advanced users might have problems with
the concept of VLAN tagging.

Limiting management access to a single arbitrary port among up to
52 possible LAN ports makes this even more difficult, for no
reason at all. Users might have reasons to use a different port
for management.  And they might even have difficulties using the
OpenWrt selected one. The port might be the wrong type for their
management link (e.g copper instead of fibre).  Or they might
depend on PoE power from a device which they can't reconfigure.

User expectations will be based on
- OpenWrt defaults for other devices
- stock firmware default for the device in question
- common default behaviour of similar devices

All 3 cases point to a static IP address accessible on the native
VLAN of any LAN port.  A switch does not have any WAN port.  All
ports are LAN ports.

This changes the default network configuration in line with these
expectations.

f8b2bc550b realtek: Remove _machine_restart and _machine_halt
By dropping _machine_restart, users can provide more reliable or
device-specific restart modes.

_machine_halt was already removed in commit f4b687d1f0 ("realtek: use
kernel defined halt"), but quietly reintroduced in commit 8faffa00cb
("realtek: add support for the RTL9300 timer"). Let's remove it again.

927570f0a3 realtek: Add and enable watchdog node
Add and enable the Realtek Otto WDT peripheral found on these SoCs.

Default all devices to use standard (cold) reboot and "soc" resets.

Devices that require the PLL value fixup before restarting, should pick
the "cpu" or "software" reset mode. These devices also need to provide a
custom reboot mode, by adding the reboot argument to the kernel command
line:

    WDT reset mode  | kernel reboot mode
    ----------------+---------------------------------------
    soc             | reboot=cold (default if not specified)
    cpu             | reboot=warm
    software        | reboot=software

Preferrably, these devices should use an alternative restart method like
gpio-restart to provide reliable restarts.

Note that watchdog restarts are not yet exposed, since the
_machine_restart override is still present.

72ae8314f5 realtek: reset both ethernet NIC and queues
Recent versions of Realtek's SDK reset both the ethernet NIC and queues
(SW_NIC_RST and SW_Q_RST bits) when initialising the hardware.

Furthermore, when issuing a CPU reset on the Zyxel GS1900-8 (not
supported by any current driver), the networking part of the SoC is not
reset. This leads to unresponsive network after the restart. By
resetting both the ethernet NIC and queues, networking always comes up
reliably.

d990f805c0 realtek: re-enable IPv6 routing
Commit 03e1d93e07 ("realtek: add driver support for routing
offload") added routing offload for IPv4, but broke IPv6 routing
completely.  The routing table is empty and cannot be updated:

 root@gs1900-10hp:~# ip -6 route
 root@gs1900-10hp:~# ip -6 route add unreachable default
 RTNETLINK answers: Invalid argument

As a side effect, this breaks opkg on IPv4 only systems too,
since uclient-fetch fails when there are no IPv6 routes:

 root@gs1900-10hp:~# uclient-fetch http://192.168.99.1
 Downloading 'http://192.168.99.1'
 Failed to send request: Operation not permitted

Fix by returning NOTIFY_DONE when offloading is unsupported, falling
back to default behaviour.

2e676c05dc realtek: fix kernel panic in DSA driver for 5.10
dsa_to_port function in 5.10 returns dsa_port from the port list in
dsa_switch_tree, but the tree is built when the switch is registered
by dsa_register_switch and it's null in rtl83xx_mdio_probe.

So, we need to use dsa_to_port after the registration of the switch.

  (include/net/dsa.h)

  added:
    - int speed
    - int duplex
    - bool tx_pause
    - bool rx_pause

- a parameter "struct switchdev_trans *trans" is added to
  port_vlan_filtering in dsa_switch_ops (include/net/dsa.h)

9a4b8d6c30 realtek: fix compile errors in rtl838x_eth.c for 5.10
this patch fixes the following errors when compiling:

- "unsigned int txqueue" is added as an additional parameter of
  ndo_tx_timeout in net_device_ops (include/linux/netdevice.h)

- "mac_link_state" in phylink_mac_ops (include/linux/phylink.h)
  is renamed to "mac_pcs_get_state" and changed the return value
  to void from int

- several parameters are added to "mac_link_up" in phylink_mac_ops
  (include/linux/phylink.h) and the order of the parameters is
  changed

  added:
    - int speed
    - int duplex
    - bool tx_pause
    - bool rx_pause

- a parameter "phy_interface_t *interface" is added to of_get_phy_mode
  (drivers/of/of_net.c) and returns the state instead of phy mode

ddaeb73de0 realtek: update soc dtsi in 5.10 for backported drivers
this patch updates SoC dtsi (rtl838x.dtsi, rtl930x.dtsi) for the
following backported drivers:

- gpio-realtek-otto (5.13)
- spi-realtek-rtl (5.12)
- irq-realtek-rtl (5.12)

And, disable SoC GPIO node (gpio0) in rtl930x.dtsi in dts-5.10.
Currently, the upstreamed driver doesn't support the GPIO controller on
RTL930x SoC.
