* ath79: dts: drop "simple-mfd" for gmacs in SoC dtsiChuanhong Guo2019-06-057-10/+10
| | | | | | | | | | | | With a proper probe deferring for ag71xx we don't need to explicitly probe mdio1 before gmac0. Drop all "simple-mfd" in SoC dtsi so that gmac orders can be the same as ar71xx. This makes eth0/eth1 order the same as those in ar71xx, which means we don't need a migration script for this anymore and we can merge incorrectly split gmac/mdio driver back together.

* ath79: ag71xx: defer probe if of_phy_connect failedChuanhong Guo2019-06-051-2/+2
| | | | | | | | | gmac0 may need a phy on builtin switch, which can be unavailable if gmac0 is probed before builtin switch. Return -EPROBE_DEFER in this case so that gmac0 can be probed later. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
* ath79: rework LED configurations for tplink,archer-d50-v1Chuanhong Guo2019-06-051-3/+3
| | | | | | | | | | | | The original one has the following problem: 1. Port mask of lan led includes wan port. 2. By using netdev trigger with vlan port, the link led is always on. This commits fixes the above problems by correcting port mask for lan led and use swconfig trigger for wan leds. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

* ath79: ag71xx: update ethtool supportPetr Štetiar2019-06-051-26/+14
| | | | | | | | | | | | ethtool doesn't work currently as phy_ethtool_ioctl expects user space pointer, but it's being passed kernel one. Fixing it doesn't make sense as {s,g}et_settings were deprecated anyway. So let's rather remove phy_ethtool_ioctl and use new {s,g}et_link_ksettings instead. While at it, update nway_reset as well.

| | | | | | | | | | | | In ar71xx v2 has blue color defined because the same mach-*.c is also used for TL-WDR4900 model with blue leds. ath79 v2 dts defines them as green.

(For example WR1000_EU_92.122.2.4987.201806261618.bin) 2) Remove the header. dd if="WR1000_EU_92.122.2.4987.201806261618.bin" of="WR1000_EU_92.122.2.4987.201806261618.bin.mod" skip=8 bs=64 3) XOR the new file with the region key.

Or, you can use this tool (CHANGE THE XOR KEY ACCORDINGLY!): https://gchq.github.io/CyberChef/#recipe=XOR(%7B'option':'Hex','string':''%7D,'',false) 4) Check the resulting decrypted image.

* ath79: set mib-poll-interval on mdio0 attached ar83xx switchPetr Štetiar2019-05-206-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit "generic: ar8216: add mib_poll_interval switch attribute" sets mib-poll-interval as disabled by default (was set to 2s), so it makes switch LEDs trigger disfunctional on devices which don't have mib-poll-interval set. So this patch sets mib-poll-interval to 500ms on devices which have ar83xx switch connected to mdio0 bus, as the same value was set for built in switches in 443fc9ac35 ("ath79: use ar8216 for builtin switch"). Some measurements performed on TP-Link Archer C7-v5: mib-type=0, mib-poll-interval=500ms (10s pidstat) Average: %usr %system %guest %wait %CPU CPU Command Average: 0.00 1.93 0.00 0.00 1.93 - kworker/0:2 iperf3 (30s): 334 Mbits/sec mib-type=0, mib-poll-interval=2s (10s pidstat) Average: %usr %system %guest %wait %CPU CPU Command Average: 0.00 1.14 0.00 0.00 1.14 - kworker/0:2 iperf3 (30s): 334 Mbits/sec So it seems like we get 4x faster LED refresh rate for additional 0.8% CPU load.

* 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.")
