-Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
- subdevices
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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").
