* realtek: Allow PHY-IDs to differ from Port numbersBirger Koblitz2022-02-171-9/+34
| | | | | | | | | We were using the PHY-ids (the reg entries in the PHY sections of the .dts) as the port numbers. Now scan the ports section in the .dts, and use the actual port numbers, following the phy-handle to the PHY properties. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>

* realtek: Replace the RTL9300 generic timer with a CEVT timerBirger Koblitz2022-02-172-196/+212
| | | | | | | | | | | | | | 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.

* realtek: Fix RTL931X Ethernet driverBirger Koblitz2022-02-171-21/+167
| | | | | | | | | | Various fixes to enable Ethernet on the RTL931X: - Network start and stop sequence for RTL931X HW - MDIO access on RTL931X SoC - Chip initialization - SerDes setup Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Fix Ethernet driver IRQ service routine for SMPBirger Koblitz2022-02-171-5/+0
| | | | | | | Do not lock the register structure in IRQ context. It is not necessary and leads to lockups under SMP load. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>

* realtek: rename rtl838x_reg structureBirger Koblitz2022-02-172-6/+6
| | | | | | | | Rename the SoC-specific rtl838x_reg structure in the Ethernet driver to avoid confusion with the structure of the same name in the DSA driver. New name is: rtl838x_eth_reg Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Fix RTL839x TX CPU-TagBirger Koblitz2022-02-171-2/+2
| | | | | | | | | | Setting bits 20 and 23 in a u16 is obviously wrong. According to https://www.svanheule.net/realtek/cypress/cputag cpu_tag[2] starts at bit 48 in the cpu-tag structure, so bit 43 is bit 5 in cpu_tag[2] and bit 40 is bit 8 in cpu_tag[2].

* realtek: Increase zone size for Ethernet driver DMABirger Koblitz2022-02-171-2/+2
| | | | | | | | | | Set CONFIG_FORCE_MAX_ZONEORDER setting to 13 to allow larger contiguous memory allocation for the DMA of the Ethernet driver. Increase the number of entries in the RX ring to 300 making use of the larger DMA region now possible for receiveing packets. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>

* realtek: Add support for RTL9300/RTL9310 I2C multiplexingBirger Koblitz2022-02-172-37/+330
| | | | | | | | | | | | 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. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Add support for RTL9300/RTL9310 I2C controllerBirger Koblitz2022-02-172-0/+550
| | | | | | | | | | This adds support for the RTL9300 and RTL9310 I2C controller. The controller implements the SMBus protocol for SMBus transfers over an I2C bus. The driver supports selecting one of the 2 possible SCL pins and any of the 8 possible SDA pins. Bus speeds of 100kHz (standard speed) and 400kHz (high speed I2C) are supported.

* realtek: remove legacy GPIO driver supportBirger Koblitz2022-02-171-474/+0

* 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.

| | | | | | | | | | | | | | | | | | | | | | | 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: 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>

| | | | | | | | | | 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.
