dmaengine: apple-admac: Fix grabbing of channels in of_xlate

2022-11-08T05:13:56Z

The of_xlate callback is supposed to return the channel after already having 'grabbed' it for private use, so fill that in.

dmaengine: apple-admac: Allocate cache SRAM to channels

2022-10-19T16:54:57Z

There's a previously unknown part of the controller interface: We have to assign SRAM carveouts to channels to store their in-flight samples in. So, obtain the size of the SRAM from a read-only register and divide it into 2K blocks for allocation to channels. The FIFO depths we configure will always fit into 2K. (This fixes audio artifacts during simultaneous playback/capture on multiple channels -- which looking back is fully accounted for by having had the caches in the DMA controller overlap in memory.)

dmaengine: apple-admac: Trigger shared reset

2022-09-29T16:13:25Z

If a reset domain is attached to the device, obtain a shared reference to it and trigger it. Typically on a chip the ADMAC controller will share a reset domain with the MCA peripheral.

dmaengine: apple-admac: Do not use devres for IRQs

2022-09-29T16:13:25Z

This is in advance of adding support for triggering the reset signal to the peripheral, since registering the IRQ handler will have to be sequenced with it. Signed-off-by: Martin Povišer Link: https://lore.kernel.org/r/20220918095845.68860-4-povik+lin@cutebit.org Signed-off-by: Vinod Koul
