Ondrej, would you please test this new series? Changed since v1: - PDMA transfer residual is calculated earlier. - End of DMA flag check is now polled (if there is any residual). Changed since v2: - Bail out of transfer loops when Gated IRQ gets asserted. - Make udelay conditional on board type. - Drop sg_tablesize patch due to performance regression. Changed since v3: - Add Ondrej's workaround for corrupt WRITE commands on DTC boards. - Reset the 53c400 logic after any short PDMA transfer. - Don't fail the transfer if the 53c400 logic got a reset. Changed since v4: - Bail out of transfer loops when Gated IRQ gets asserted. (Again.) - Always call wait_for_53c80_registers() at end of transfer. - Drain chip buffers after PDMA receive is interrupted. - Rework residual calculation. - Add new patch to correct DMA terminology. Changed since v5: - Rework residual calculation to account for on-chip buffer swap. - Attempt to retain the disconnect/IRQ detection in the DTC436 workaround. - Move all DTC436 workarounds to final patch.
