Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
|
|
subdevices

|
For bus devices to be fully usable it's required to set their DMA
|
|
parameters.
|
|
|
|
For years it has been missing and remained unnoticed because of
|
|
mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
|
|
Kernel 4.19 came with a lot of DMA changes and caused a regression on
|
|
the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
|
|
dma noncoherent ops for simple noncoherent platforms") DMA coherent
|
|
allocations just fail. Example:
|
|
[ 1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
|
|
[ 1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
|
|
[ 1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
|
|
[ 1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
|
|
|
|
This change fixes above regression in addition to the MIPS bcm47xx
|
|
commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
|
|
|
|
It also fixes another *old* GPIO regression caused by a parent pointing
|
|
to the NULL:
|
|
[ 0.157054] missing gpiochip .dev parent pointer
|
|
[ 0.157287] bcma: bus0: Error registering GPIO driver: -22
|
|
introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
|
|
use GPIOLIB_IRQCHIP").
