#1383314 — [PATCH 0/3] Cypress FM33256B processor companion support

Hi,

This series adds support for the Cypress Semiconductor FM33256B processor
companion. The device contains a 256 kbit FRAM, an RTC, a supply voltage
monitor, and a watchdog timer. Only the FRAM and RTC are supported by these
patches.

The device is implemented as an MFD device. The FRAM interface is currently
implemented as an SPI regmap, wrapped by a binary sysfs file. If another
interface would be a better choice, please let me know.

Thanks,

-Jeppe

There is now an nvmem framework that will allow you to easily have both
an in-kernel and a userspace interface.
