The MT7622 device tree never bothered to specify the number of virtual DMA
|
|
channels for the HSDMA controller, always falling back to the default value of
|
|
3. Make this value explicit, in order to avoid the following dmesg notification:
|
|
|
|
mtk_hsdma 1b007000.dma-controller: Using 3 as missing dma-requests property
