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 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. Also now a new syscon abstraction "syscon_regmap_read_from_offset" is implemented and exported from syscon allowing accessing a register from a syscon reference like this ocotp-cfg1 = <&ocotp 0x20>; avoiding code repetition in the driver. 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. This patch series is based on top of shawn's for-next branch and tested on Colibri Vybrid VF50 and VF61 modules. Feedback is most welcome.
