Hello, This patchset implements SoC bus support for Freescale Vybrid platform, implementing the following https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-soc Currently the required information is more or less read across the whole SoC, but I guess we cannot change that since these are the locations with the required information. There seem to be three options for the revision field: - ROM revision (see https://community.freescale.com/docs/DOC-94802) - ANADIG revision (ANADIG_DIGIPROC, as used for the i.MX SoC's) - OCOTP revision Some numbers: Colibri VF61 1.1A (2N02G) - 0x00000013 - 0x00610000 - 0x01000000 - 0x410000c8 Colibri VF61 V1.0B (1N02G) - 0x00000011 - 0x00610000 - 0x01000000 - 0x410000c8 Colibri VF61 V1.0A (which is actually a VF600 SoC, no L2 cache, since that was the only one we could buy back then, 1N02G printed on it) - 0x00000011 - 0x00610000 - 0x01000000 - none... Colibri VF50 V1.0A (1N02G) - 0x00000011 - 0x00610000 - 0x01000000 - none... Vybrid Tower Rev J (1N02G) - 0x00000011 - 0x00610000 - 0x01000000 - 0x410000c8 The ROM revision differs the most, so we would like to go with the revision information from the ROM register 0x80. Version 1 of the patchset can be found here http://www.spinics.net/lists/devicetree/msg80257.html The RFC version can be found here https://lkml.org/lkml/2015/5/11/13 Changes since v1: - Sort the headers in alphabetical order Changes since RFC: - Use a DT entry for the ROM area while specifying it as syscon.
