* ramips: mt7620: move mt7620_mdio_mode() to ethernet driverMichael Pratt2021-06-232-49/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The function mt7620_mdio_mode is only called once and both the function and mdio_mode block have been named incorrectly, leading to confusion and useless commits. These lines in the mdio_mode block of mt7620_hw_init are only intended for boards with an external mt7530 switch. (see commit 194ca6127ee18cd3a95da4d03f02e43b5428c0bb) Therefore, move lines from mdio_mode to the place in soc_mt7620.c where the type of mt7530 switch is identified, and move lines from mt7620_mdio_mode to a main function. mt7620_mdio_mode was called from mt7620_gsw_init where the priv struct is available, so the lines must stay in mt7620_gsw_init function. In order to keep things as simple as possible, keep the DTS property related function calls together, by moving them from mt7620_gsw_probe to init. Remove the now useless DTS properties and extra phy nodes.

* ramips: mt7620: use DTS to set PHY base address for external PHYsMichael Pratt2021-06-231-6/+4
| | | | | | | | | | | | | | | | | | | | | | | Set the PHY base address to 12 for mt7530 and 8 for others, which is based on the default setting for some devices from printing the register with the following command after it is written to by uboot during the boot cycle. `md 0x10117014 1` PHY_BASE option only uses 5 bits of the register, bits 16 to 20, so use 8-bit integer type. Set the option using the DTS property mediatek,ephy-base and create the gsw node if missing. Also, added a kernel message to display the EPHY base address. Note: If anything is written to a PHY address that is greater than 1 hex char (greater than 0xf) then there is adverse effects with Atheros switches. Signed-off-by: Michael Pratt <mcpratt@pm.me>
* ramips: mt7620: allow both internal and external PHYsMichael Pratt2021-06-231-62/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the new variable ephy_base was introduced, it was not applied to the if block for mdio_mode. The first line in the mdio_mode if block sets the EPHY base address to 12 in the SOC by writing a register, but the corresponding variable in the driver was still set to the default of 0. This causes subsequent lines that write registers with the function _mt7620_mii_write to write to PHY addresses 0 through 4 while internal PHYs have been moved to addresses 12 through 16. All of these lines are intended only for PHYs on the SOC internal switch, however, they are being written to external ethernet switches if they exist at those PHY addresses 0 through 4. This causes some ethernet ports to be broken on boards with AR8327 or QCA8337 switch. Other suggested fixes move those lines to the else block of mdio_mode, but removing the else block completely also fixes it. Therefore, move the lines to the mt7620_hw_init function main block, and have only one instance of the function mtk_switch_w32 for writing the register with the EPHY base address. In theory, this also allows for boards that have both external switches and internal PHYs that lead to ethernet ports to be supported.

* ramips: mt7620: fix ethernet driver GMAC port initMichael Pratt2021-06-232-15/+9
| | | | | | | | | | | | | | | | | | | | | | | A workaround was added to the switch driver to set SOC port 4 as an RGMII GMAC interface based on the DTS property mediatek,port4-gmac. (previously mediatek,port4) However, the ethernet driver already does this, but is being blocked by a return statement whenever the phy-handle and fixed-link properties are both missing from nodes that define the port properties. Revert the workaround, so that both the switch driver and ethernet driver are not doing the same thing and move the phy-handle related lines down so nothing is ending the function prematurely. While at it, clean up kernel messages and delete useless return statements.

* ramips: mt7620: remove useless GMAC nodesMichael Pratt2021-06-231-1/+4
| | | | | | | | | | | | | | | | | | | These nodes are used for configuring a GMAC interface and for defining external PHYs to be accessed with MDIO. None of this is possible on MT7620N, only MT7620A, so remove them from all MT7620N DTS. When the mdio-bus node is missing, the driver returns -NODEV which causes the internal switch to not initialize. Replace that return so that everything works without the DTS node. Also, an extra kernel message to indicate for all error conditions that mdio-bus is disabled. Fixes: d482356322c9 ("ramips: mt7620n: add mdio node and disable port4 by default") Fixes: aa5014dd1a58 ("ramips: mt7620n: enable port 4 as EPHY by default") Signed-off-by: Michael Pratt <mcpratt@pm.me>
* ramips: mt7620: simplify DTS properties for GMACMichael Pratt2021-06-233-18/+6
| | | | | | | | | | | | | | | | | | | There are only 2 options in the driver for the function of mt7620 internal switch port 4: EPHY mode (RJ-45, internal PHY) GMAC mode (RGMII, external PHY) Let the DTS property be boolean instead of string where EPHY mode is the default. Fix how the properties are written for all DTS that use them, and add missing nodes where applicable, and remove useless nodes, and minor DTS formatting. Signed-off-by: Michael Pratt <mcpratt@pm.me>

* ramips: mt7530 swconfig: fix race condition in register accessDENG Qingfang2021-04-151-6/+10
| | | | | | | | | | | | | | | | The mt7530_{r,w}32 operation over MDIO uses 3 mdiobus operations and does not hold a lock, which causes a race condition when multiple threads try to access a register, they may get unexpected results. To avoid this, handle the MDIO lock manually, and use the unlocked __mdiobus_{read,write} in the critical section. This fixes the "Ghost VLAN" artifact[1] in MT7530/7621 when the VLAN operation and the swconfig LED link status poll race between each other.

* ramips: remove further mt7621 code from local ethernet driverAdrian Schmutzler2020-08-265-265/+2
| | | | | | | | | | | | | | | While commit 734a8c46e703 focussed on removing stuff directly selected by the NET_RALINK_* symbols, this patch removes additional unused mt7621-specific code from the ethernet driver. As with the previous patch, the main reason is to reduce the amount of code we have to maintain and care about. Note that this patch still keeps a few lines with IS_ENABLED(CONFIG_SOC_MT7621) in mtk_eth_soc.h/.c, as this file is still selected for the mt7621 subtarget.

* ramips: remove legacy ethernet driver components for mt7621Adrian Schmutzler2020-08-218-1433/+6
| | | | | | | | | | | | | | | | The mt7621 subtarget has been switched to DSA quite a while ago and seems to run sufficiently fine. Build with older kernels than 5.4 has been disabled directly during the kernel bump, so our local ethernet driver is unused in master since then. Therefore, let's remove the mt7621-specific parts of "our" ethernet driver, so we don't have to maintain them and it's obvious to everybody that they are not used anymore. This also drops the offloading components as this was specifically implemented to depend on mt7621. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* ramips: Enable rx of 1536 bytes ethernet frames on MT7621John Crispin2015-10-051-4/+4
| | | | | | | | | | | The default switch frame size (with FCS + header) is 1536 bytes. But the GMAC only accepted frames up to 1522 bytes. Setting it to 1536 allows to receive ethernet frames using the full of MTU 1500 + an extra VLAN header + VLAN header added by the switch.

* ramips: Fix too small rx bufferJohn Crispin2015-10-051-4/+12
| | | | | | | | | | | | | | | | | | The driver assumes that the maximum received buffer for non-jumbo frames is 1536 bytes. But the allocation of the rx fragment doesn't reflect that. It currently allocates fragments which will only be large enough to be used as rx buffer with the size of 1534 bytes. This is problematic because the GMAC will now try to write to 2 bytes which don't belong to its receive buffer when a large enough ethernet frame is received. This may already be a problem on existing chips but will at least become a problem when the 1536 byte rx modus is enabled on MT7621a. It is required on this SoC to receive ethernet frames which use their full 1500 bytes MTU and a VLAN header next to the switch VLAN tag.

* ramips: Fix setting of rx buffer lengthJohn Crispin2015-10-052-2/+3
| | | | | | | | | | | | | | The length of the DMA rx buffer was always set to 0 because the function for extracting the length was used to calculate the value for setting it. Instead the macro has to be split in a get and set function similar to the TX_DMA_(GET_|)PLEN(0|1) macro. No problem was noticed on MT7621a before this was changed and thus maybe it was hidden by different problem which is not yet fixed.

* ramips: Allow to receive vlan over untag ports on MT7530John Crispin2015-10-051-3/+33
| | | | | | | | | | | | | | | | | | | | The MT7530 switch driver with enable_vlan set will automatically set all ports to the user port mode. The hardware will remove the incoming vlan tag on these ports and use it for its internal vlan. This is usually not wanted and makes it impossible to communicate via vlan over the switch in both directions. It is possible to configure a switch port to "transparent mode" when this port is only used as untag in the switch VLANs. This will disable the VLAN untagging of packets when they were received on this port. The tagging on "tag" ports based on the vlan id is still working. The transparent port mode cannot be used when a port is both used in a VLAN as "tag" and in another one as "untag" port. Signed-off-by: Sven Eckelmann <sven@open-mesh.com> SVN-Revision: 47114
