Adrian Schmutzler	8fe5ad5d33	brcm47xx: rename target to bcm47xx ... This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>	2020-02-14 14:10:51 +01:00
Rafał Miłecki	7175b1356e	brcm47xx: backport MIPS fix adding struct device for the SoC ... It's needed to: 1) Fix GPIOLIB_IRQCHIP as in 4.19 there is no bcma revert anymore 2) Fix /sys/devices/ 3) Fix dma_zalloc_coherent() regression It still needs a bcma change that will follow later.

Rafał Miłecki	25d8aa7d02	brcm47xx: add support for the kernel 4.19 ... 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] ...
