linux-toradex.git/drivers/rtc/nvmem.c, branch v4.16-rc6 Linux kernel for Apalis and Colibri modules rtc: add generic nvmem support 2017-07-07T11:14:14+00:00 Alexandre Belloni alexandre.belloni@free-electrons.com 2017-07-06T09:42:02+00:00 697e5a47aa12cdab6f2a8b284cc923cdf704eafc Many RTCs have an on board non volatile storage. It can be battery backed RAM or an EEPROM. Use the nvmem subsystem to export it to both userspace and in-kernel consumers. This stays compatible with the previous (non documented) ABI that was using /sys/class/rtc/rtcx/device/nvram to export that memory. But will warn about the deprecation.
