One patch that wasn't ported due to a lot of conflict is: 901-Revert-bcma-switch-GPIO-portions-to-use-GPIOLIB_IRQC.patch Hopefully a correct/real fix will get developed before we switch brcm47xx to the 4.14. This IS NOT ready for switching/trying/using 4.19 yet due to some DMA regression affecting bgmac: [ 0.945472] bgmac_bcma bcma0:2: Found PHY addr: 25 [ 0.954565] libphy: bcma_mdio mii bus: probed [ 0.959486] ------------[ cut here ]------------ [ 0.964387] WARNING: CPU: 0 PID: 1 at ./include/linux/dma-mapping.h:516 bgmac_enet_probe+0x1b4/0x5c4 [ 0.973751] Modules linked in: [ 0.976913] CPU: 0 PID: 1 Comm: swapper Not tainted 4.19.9 #0 [ 0.982750] Stack : 804a0000 804597c4 00000000 00000000 80458fd8 8381bc2c 838282d4 80481a47 [ 0.991367] 8042e3ec 00000001 804d38f0 00000204 83980000 00000065 8381bbe0 6f55b24f [ 0.999975] 00000000 00000000 80520000 00002018 00000000 00000075 00000007 00000000 [ 1.008583] 00000000 80480000 000ee811 00000000 00000000 00000000 80432c00 80248db8 [ 1.017196] 00000009 00000204 83980000 803ad7b0 00000000 801feeec 00000000 804d0000 [ 1.025804] ...

Subject: [PATCH] MIPS: BCM47XX: Enable USB power on Netgear WNDR3400v3
|
|
|
|
Setting GPIO 21 high seems to be required to enable power to USB ports
|
|
on the WNDR3400v3. As there is already similar code for WNR3500L,
|
|
make the existing USB power GPIO code generic and use that.
