- The 'dma-ranges' helps to take care of few DMAable system memory restrictions by use of dma_pfn_offset which is maintained per device. Arch code then uses it for dma address translations for such cases. We update the dma_pfn_offset accordingly during DT the device creation process. - The 'dma-coherent' property is used to setup arch's coherent dma_ops. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJTajacAAoJEHJsHOdBp5c/780QAJN50zmxyZ7sqA9xGum8MSJl Vjpp1mw3eu7dZ1HoWcpn35l0tOEVpU/wo4ymtt6YYUhD3Po2LZCl3e43h91B/9/B Ih++WZaN+UmpUpp9YJyeS9pkl0wwEqSmJyTBXZrhFhl4o3KNQlHWPGOMJ5CBPaA0 Z03TT1MeOMiCo10xz6JCA/DjPnQz9m5ClxNXLwdP1KOiTDDsv4gtkTZ0UenttIoU DTerJ+GIt1Gzb+P92aGvuc9wgLKacYmH599m6fQcmd9cIG2oMN2Xdxzfqo56v7Sb TGwFcKWYlhPDbDPmcPlidS6j4O+r8cMRwgHLO3r6LHJezCGQOYU8GzN7m6DKt4ww lCIR/k9u4YY/ZiLFeQ+G0Au8T1J6DHdbCI5sciFI53XYT4HMsV1aNpogOim7adC8 4bPRmGCIN03aW+2ynLkFkdnXSBnaAyjt6qlr5zP8owsKDkV7+0WadQqyD2ovQ0FE sBt1HtOUGUsiR/97J4JFBGFxb84zMa6hXhFVUeFbyScCJNm2gkKeRQfiiB4mZi9L NAX/KVGyS6dktJaoLUiKi/p7aqOat3ezD1PrCziq4ceyWbDLag8Bq9H7rtb7vvqC ulHDUPfRy3Z9kmV8+QAznqPJVY1IHXJ18A+YFXF5ktr+5CJ51C8HjVZP3GZKncPC LpA1rRUEwEqsAwnjzcXW =Q7n3 -----END PGP SIGNATURE----- Merge tag 'dt-dma-properties-for-arm' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone into devel-stable DT support for 'dma-ranges'and 'dma-coherent' properties with ARM updates - The 'dma-ranges' helps to take care of few DMAable system memory restrictions by use of dma_pfn_offset which is maintained per device.
