From: Adrian Hunter Date: Tue, 4 Nov 2014 10:42:46 +0000 (+0200) Subject: mmc: sdhci: Add 64-bit ADMA support X-Git-Tag: omap-for-v3.19/fixes-for-merge-window~28^2~58 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e57a5f61eae7e145aeeda18ccb22576822f534bf;p=pandora-kernel.git mmc: sdhci: Add 64-bit ADMA support Add 64-bit ADMA support including: - add 64-bit ADMA descriptor - add SDHCI_USE_64_BIT_DMA flag - set upper 32-bits of DMA addresses - ability to select 64-bit ADMA - ability to use 64-bit ADMA sizes and alignment - display "ADMA 64-bit" when host is added It is assumed that a 64-bit capable device has set a 64-bit DMA mask and *must* do 64-bit DMA. A driver has the opportunity to change that during the first call to ->enable_dma(). Similarly SDHCI_QUIRK2_BROKEN_64_BIT_DMA must be left to the drivers to implement.
