  "message": "atmel_serial: add DMA support\n\nThis patch is based on the DMA-patch by Chip Coldwell for the AT91/AT32 serial\nUSARTS, with some tweaks to make it apply neatly on top of the other patches\nin this series.\n\nThe RX and TX code has been moved to a tasklet and reworked a bit.  Instead of\ndepending on the ENDRX and TIMEOUT bits in CSR, we simply grab as much data as\nwe can from the DMA buffers.  I think this closes a race where the ENDRX bit\nis set after we read CSR but before we read RPR, although I haven\u0027t confirmed\nthis.\n\nSimilarly, the two TX handlers (ENDTX and TXBUFE) have been combined into one.\n Since the current code only uses a single TX buffer, there\u0027s no point in\nhandling those interrupts separately.\n\nThis also fixes a DMA sync bug in the original patch.\n\n[linux@bohmer.net: rebased onto irq-splitup patch]\n[hskinnemoen@atmel.com: moved to tasklet, fixed dma bug, misc cleanups]\n[hskinnemoen@atmel.com: atmel_serial dma: Misc fixes and cleanups]\nSigned-off-by: Remy Bohmer \u003clinux@bohmer.net\u003e\nSigned-off-by: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nCc: Andrew Victor \u003clinux@maxim.org.za\u003e\nTested-by: Marc Pignat \u003cmarc.pignat@hevs.ch\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
