Subject: [PATCH v6 0/6] g_NCR5380: PDMA fixes and cleanup
Date: Fri, 30 Jun 2017 22:40:53 -0400 (EDT) [thread overview]
Message-ID: <cover.1498876618.git.fthain@telegraphics.com.au> (raw)
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.
