Subject: [PATCH 0/4] 8250: DMA Fixes
Date: Mon, 7 Nov 2022 13:07:04 +0200 [thread overview]
Message-ID: <20221107110708.58223-1-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.
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
