I'm still getting issues for SPI with this:
[ 50.952845] s3c64xx-spi s3c6410-spi.0: Failed to get RX DMA channel
[ 50.953520] spi_master spi0: failed to prepare transfer hardware
when I test (with -next with this series applied on top), this is from
the first transfer that tries to DMA - there's actually no RX data. No
errors are reported by the DMA controller itself. I'm also getting
crashes setting up the audio DMA while derferencecing the channel.
This is without DT - are there any hookups missing because of that?
