* apm821xx: provide legacy interrupts for PCIe in DTChristian Lamparter2020-09-055-0/+9
| | | | | | | | | | | | | | | | | | | | | | Devices with PCIe-Switches like the WNDR4700, MR24 and WNDAP660 need to have the interrupts property specified in the device-tree for the legacy pci interrupt signaling method to work. If the proper interrupt value is not specified, the default INTA IRQ 12 is taken for all devices. This is especially bad, if the device is setup to use INTC, because these interrupts will not be serviced. Russell Senior reported his experience on the MR24: "The symptom is client devices can't see the beacons. Wifi ifaces appear, can scan and hear other networks, but clients can't see the MR24's SSIDs." (The interrupts-property on the WNDAP620 was optional since it uses INTA by default. Likewise the MX60W is in the same category) Reported-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

* treewide: drop DEVICE_TYPE when used as device variableAdrian Schmutzler2020-06-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | DEVICE_TYPE is a target/subtarget variable, and it does not have any effect when set in a device definition. It can only be set in a target's or subtarget's Makefile. Consequently, having it set anyway is misleading, so this drops all cases.

* apm821xx: use the real default HZ value from upstreamChristian Lamparter2020-04-101-84/+3
| | | | | | | | | | | | | | | | | | | | With the "real HZ" debate out of the way, let's actually use the apm821xx's default upstream config file at arch/powerpc/configs/44x/bluestone_defconfig. From what I can tell, it sets NO_HZ (well, this platform was for NAS, so this is a bit unexpected) and remove any specific HZ_$VALUE symbol. Sadly, Daniel Engberg didn't run any before/after netperf tests, because it would have been such a slam dunk across the boards. In case of the apm821xx the tcp tx/rx performance improved ~14% (from 600Mbps to 700Mps). This now causes the emac to drop frames too, so let's see if this is causes more problems or not. This patch includes a refresh of the configuration too. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
