* kernel: fix swconfig compilation with kernels 5.2+Rafał Miłecki2019-10-281-0/+23

* generic: ar8216: group MIB counters and use two basic ones only by defaultChuanhong Guo2019-05-203-81/+150
| | | | | | | | | | | | | | | | | There are too many MIB counters that almost nobody needs since commit d6366ce3665f ("generic: ar8216: mib_work_func: read all port mibs everytime"). In the worker function to poll MIB data, it deals with all ports instead of only one port every time, which introduces too many mdio operations that it becomes a heavy CPU load even on not-emulated MDIO bus. This commit groups MIB counters and enable only TxBytes and RxGoodBytes by default (both of which are necessary to get swconfig led working.) and adds an swconfig attribute to allow enabling all counters if users need them.

* generic: ar8216: add mib_poll_interval switch attributeChuanhong Guo2019-05-203-8/+63
| | | | | | | | | | | | | | This allows specifying interval of polling MIB counters from userspace and allow completely turning off MIB counter support by setting mib_poll_interval to 0. Since MIB counter polling is a heavy CPU load for GPIO emulated MDIO bus, disable this behavior by default. Those who wants to use swconfig LEDs can enable them with qca,mib-poll-interval dts property or with swconfig command. Fixes: FS#2230 ("kworker spikes 100% cpu every 2 second.")

* generic: ar8216: do a software reset for switch during hw_initChuanhong Guo2019-03-241-0/+3
| | | | | | | | | | | | | | This applies to ar8216 and ar8236. QCA's newer U-boot will enable the switch mdio master for FE switches which makes phy inaccessible from CPU mdio. (e.g. on TP-Link TL-WR941N v7 Chinese version which uses QCA9558+AR8236.) For these devices PHY probing is broken and mdio device probing is a must. We also need to disable switch mdio master in driver for later PHY initialization. Do a soft reset during hw_init so that mdio master can be disabled and expose PHYs to CPU mdio for later PHY accessing. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

* generic: ar8216: add support for get_port_stats()Chuanhong Guo2019-03-243-25/+59
| | | | | | | | | | | | | | | | | | | | | | | Partially reverts commit eff3549c5883a9abc5dbff00c084cabbcfdf4437. AR7240 and AR9341 have buggy hardware switch LED trigger. The AR7240 one doesn't blink and the blinking of port0/port5 is reversed on AR9341 if we swap PHY0 and PHY4. (Only blinking is reversed, which means LED for PHY0 will lit when PHY0 is link up and will blink when PHY4 has active link and vice versa.) On these two chips a software swconfig LED trigger is required. This commit adds swconfig port stats back but: 1. move checking of mib_t/rxb_id into ar8xxx_chip since we can't distinguish ar7240sw and ar8216 using only chip id. 2. don't update mib counter in get_port_stat. This function is called every 0.01s and this capturing procedure will take up a lot of CPU. We already have a mib_work_func updating mib counters every 2s so return the saved counter instead of fetching new data. The blinking rate will be weird but it should solve the previously mentioned CPU time problem. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
* generic: ar8216: add support for ar724x/ar933x builtin switchChuanhong Guo2019-03-242-6/+112
| | | | | | | | | | | | | | This builtin switch is a bugless ar8216 with different mib counters and gigabit cpu port. Atheros uses the same device ID and it's impossible to distinguish the standalone one and the builtin one. So we add support to mdio device probe only. This switch doesn't have buggy vlan tag so it's not needed to enable atheros header. This commit changed ar8216_setup_port so that it can be reused for this switch.

* generic: ar8216: add support for separated mdio bus for phy accessChuanhong Guo2019-03-242-1/+37
| | | | | | | | | | | | | | Atheros FE switches have a builtin mdio master available for PHY accessing and on ar724x/ar933x builtin switches this mdio master is the only way of accessing PHYs. After this patch if there is phy_read/phy_write method available in ar8xxx_chip we register a separated mdio bus for accessing PHYs. Still adds support for mdio device probing only since this isn't needed for those switches registered using PHY probing. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
* generic: ar8216: add support for ar8229Chuanhong Guo2019-03-242-5/+144
| | | | | | | | | | | | | | | | ar8229 is the builtin switch in ar934x and later chips. There is also a standalone version available and their registers/functions are the same. This commit added support for the builtin ar8229. The only thing missing for standalone ar8229 should be phy modes. Since I don't have a router using that, this commit doesn't add support for other phy modes. Only add its support for mdio-device probing method because the current PHY probing can't return 1G speed when it's a FE switch. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the patches which were just copied in the previous commit apply on top of kernel 4.19. The patches in the backports-4.19 folder were checked if they are really in kernel 4.19 based on the title and only removed if they were found in the upstream kernel.

* generic: rtl836x: support defered probe on mdio-busChristian Lamparter2018-11-265-13/+17
| | | | | | | | | | | | | | | | On the WNDAP620, the mdio and mdc lines are controlled by the EMAC ethernet device. This results in a hen-vs-egg problem. The rtl8367b driver is probed before the ethernet driver and the mdio-bus is not available yet, which caused the rtl8367b driver to fail. This patch changes the rtl8366_smi_probe_of() function to return -EPROBE_DEFER if the mdio-bus lookup failed and changes rtl8366_smi_probe()'s signature to return the error code back to the callee, so it can propagate back to the kernel. Which, will retry the switch probe at a later time. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
* kernel: b53: register switch on probeDavid Bauer2018-11-231-22/+21

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add sysfs 'mode' attribute to swconfig controlled LEDs. swconfig 'link state' LEDs blink in the presence of port traffic. This behaviour becomes more obvious as switches start to support get_port_stats() e.g. commits 0369e358916ef092a1644334f5dd1412051b68a4, 3056d09b4046e0eb0f6de0f3f5432cd9fa86fc51, 4ddbc43cc15c2fa128a2f169964ef7eb508cf2c5, 4d8a66d9346373c2a7fcac5bdae3f662a9dbd9df. This blinking can be confusing/distracting if the switch has other LEDs used to indicate traffic. Provide a 'mode' sysfs attribute that controls the blink on traffic behaviour. mode - either "none" (LED is off) or a space separated list of one or more: link: LED's normal state reflects whether the link is up (has carrier) or not tx: LED blinks on transmitted data rx: LED blinks on receive data Note that 'link' considers any port speed mask that may be applicable. e.g. if an LED is configured to indicate 1Gbit link speed and mode is set to 'link rx tx' but the port is connected at 100Mbit then the LED will not light or blink. A mode of 'tx rx' will blink in the presence of traffic only if the port matches the rate (if configured) This maintains compatibility with existing behaviour. Attribute is 'link tx rx' by default for backwards compatible behaviour.

| | | | | | | | | | | | | | | | The implementation is not efficient on ar8xxx switches. It triggers high CPU load and degrades device performance.
