Revision cde4384e1037c15e5dd04c68d19c75798b6281dd authored by Florian Fainelli on 20 April 2012, 13:37:33 UTC, committed by Grant Likely on 27 April 2012, 17:15:41 UTC
This patch converts the bcm63xx SPI driver to use the SPI infrastructure pump message queue. Since we were previously sleeping in the SPI driver's transfer() function (which is not allowed) this is now fixed as well. To complete that conversion a certain number of changes have been made: - the transfer len is split into multiple hardware transfers in case its size is bigger than the hardware FIFO size - the FIFO refill is no longer done in the interrupt context, which was a bad idea leading to quick interrupt handler re-entrancy Tested-by: Tanguy Bouzeloc <tanguy.bouzeloc@efixo.com> Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
