This patchset implements SoC bus support for Freescale Vybrid platform, implementing the following https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-soc This a reworked version of an older patchset series posted in June 2015 which was at v5 then [1]. Since the NVMEM framework was then getting introduced, we decided that first a NVMEM driver for OCOTP peripheral being in place would be better. Compared to the older revisions, this driver now relies on NVMEM consumer API using the NVMEM based vf610_ocotp driver which has already been in mainline for a while now. One point on which we were not sure here is whether we really should introduce a new Kconfig symbol as being introduced here. While we could just enable it when SOC_VF610 is selected, this however would introduce circular dependencies. Feedback is most welcome. @Rob Herring Does this patchset address the concerns you had? Changes since v2: 1. Remove syscon_regmap_read_from_offset function and use the available syscon functions 2. Remove fsl,vf610-soc-bus and related bindings at SoC node level and introduce a fsl,vf610-soc node which is used by the driver to bind and has all the required phandles plus the NVMEM consumer handles. 3. Fix memory leak. of_node_put was not called for returned node of of_parse_phandle and memory allocated by nvmem_cell_read was not freed explicitly in return error paths. Changes since v1: Add device tree binding documentation. 2016: v2 patchset https://lkml.org/lkml/2016/5/2/69 2016: v1 patchset https://lkml.org/lkml/2016/3/11/132 [1] Older v5: http://lkml.iu.edu/hypermail/linux/kernel/1506.0/03787.html Even earlier versions: Version 4 of the patchset can be found here https://lkml.org/lkml/2015/5/26/199 Version 3 of the patchset can be found here http://www.spinics.net/lists/arm-kernel/msg420847.html Version 2 of the patchset can be found here http://www.spinics.net/lists/devicetree/msg80654.html 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 Regards, Sanchayan.
