* realtek: Remove _machine_restart and _machine_haltSander Vanheule2021-11-241-85/+0
| | | | | | | | | | | | | | By dropping _machine_restart, users can provide more reliable or device-specific restart modes. _machine_halt was already removed in commit f4b687d1f053 ("realtek: use kernel defined halt"), but quietly reintroduced in commit 8faffa00cb6b ("realtek: add support for the RTL9300 timer"). Let's remove it again.

* realtek: reset both ethernet NIC and queuesSander Vanheule2021-11-241-4/+7
| | | | | | | | | | | | | | | 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.

* realtek: re-enable IPv6 routingBjørn Mork2021-10-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Commit 03e1d93e0779 ("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.

* realtek: add legacy realtek GPIO driver for rtl9300 supportBirger Koblitz2021-10-092-0/+481
| | | | | | | The otto GPIO driver does not work with rtl9300 SoCs. Add the legacy driver again and use that by default in the 9300 .dtsi Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Fix bug when accessing external PHYs on SoCs older than Revision CBirger Koblitz2021-10-091-3/+22
| | | | | | | | | | RTL8393 SoCs older than Revision C hang on accesses to PHYs with PHY address larger or equal to the CPU-port (52). This will make scanning the MDIO bus hang forever. Since the RTL8390 platform does not support more than 52 PHYs, return -EIO for phy addresses >= 52. Note that the RTL8390 family of SoCs has a fixed mapping between port number and PHY-address.

* realtek: Fix bug in VLAN ingress and egress filteringBirger Koblitz2021-10-091-4/+4
| | | | | | | | | | | The ingress filter registers use 2 bits for each port to define the filtering state, whereas the egress filter uses 1 bit. So for for the ingress filter the register offset for a given port is: (port >> 4) << 4: since there are 16 entries in a register of 32 bits and for the egress filter: (port >> 5) << 4: since there are 32 entries in a register of 32 bits Signed-off-by: Birger Koblitz <git@birger-koblitz.de>

* realtek: ensure output drivers are enabled in RTL8231Paul Fertser2021-10-021-5/+7
| | | | | | | | | | | | | The bootloader can leave the GPIO expander in a state which doesn't have output drivers enabled so GPIOs will properly work for input but output operations will have no effect. To avoid disrupting the boot in case the bootloader left direction and data registers in an inconsistent state (e.g. pulling SoC's reset to 0) reconfigure everything as input.

* realtek: fix kernel panic in DSA driver for 5.10INAGAKI Hiroshi2021-09-261-2/+8
| | | | | | | | | | 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.
