2018-03-14nvmem: add i.MX7 support to snvs-lpgprAndrey Yurovsky1-6/+21
The i.MX7 family has similar SNVS hardware so make the snvs-lpgpr support it along with the i.MX6 family. The register interface is the same except for the number and offset of the general purpose registers.

2018-03-14nvmem: snvs_lpgpr: Convert commas to semicolonsAndrey Smirnov1-6/+6
Looks like commas were accidentally used where semicolons were supposed to be. Fix that.

2017-10-04nvmem: add snvs_lpgpr driverOleksij Rempel1-0/+156
This is a driver for Low Power General Purpose Register (LPGPR) available on i.MX6 SoCs in Secure Non-Volatile Storage (SNVS) of this chip. It is a 32-bit read/write register located in the low power domain. Since LPGPR is located in the battery-backed power domain, LPGPR can be used by any application for retaining data during an SoC power-down mode.
