From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicolas Ferre Subject: [PATCH 0/5] spi: atmel: enhance the DMA handling Date: Thu, 24 Nov 2016 12:24:56 +0100 Message-ID: Mime-Version: 1.0 Content-Type: text/plain Cc: , , , , , Nicolas Ferre To: Mark Brown , Return-path: Sender: linux-spi-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-ID: Use the dummy buffer handling and DMA mapping core infrastructure to simplify spi-atmel driver. By using these frameworks we also fix the use of any kind of memory with dmaengine. This work was triggered by issues encountered while using UBI/UBIFS on a serial flash. Some good ideas of this series have been inspired by spi-rspi.c and commits by Geert Uytterhoeven. I have a side question still: is the is_dma_mapped tag still used and considered into the core spi routines or is it always the driver itself that have to deal with it (so how to do with the can_dma() routine)?
