From: Al Viro Date: Wed, 4 May 2005 04:39:22 +0000 (+0100) Subject: [PATCH] ISA DMA Kconfig fixes - part 1 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5cae841b13f23ccdf7e38b2400b5cf57deb57ccf;p=openwrt%2Fstaging%2Fblogic.git [PATCH] ISA DMA Kconfig fixes - part 1 A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.
