Subject: [PATCH v2 0/4] 8250: DMA Fixes
Date: Tue, 8 Nov 2022 14:19:48 +0200 [thread overview]
Message-ID: <20221108121952.5497-1-ilpo.jarvinen@linux.intel.com> (raw)
Here are a number of 8250 DMA related fixes. The last one seems the
most serious problem able to corrupt the payload ordering.
v2:
- Tweak configure logic to match Andy's suggestion
- Cleaned up the tags from the oneliner patch
Ilpo Järvinen (4):
serial: 8250: Fall back to non-DMA Rx if IIR_RDI occurs
serial: 8250_lpss: Configure DMA also w/o DMA filter
serial: 8250_lpss: Use 16B DMA burst with Elkhart Lake
serial: 8250: Flush DMA Rx on RLSI
