The Maxim MAX77759 is a companion PMIC for USB Type-C applications and
includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C
Port Controller (TCPC), NVMEM, and a GPIO expander.
This driver exposes the non volatile memory using the platform device
registered by the core MFD driver.
In preparation for adding more type checking to the memtostr/strtomem*()
helpers, introduce the ability to check for the "nonstring" attribute.
This is the reverse of what was added to strscpy*() in commit 559048d156ff
("string: Check for "nonstring" attribute on strscpy() arguments").

Document the compatible string for the Exynos7870 PMU. It's compatible
with the Exynos7 PMU design. It handles syscon reboot, syscon reboot mode,
as well as other system control registers (i.e registers for the USB PHY).

Dear Linux Hardening, Security, and Memory Management Mailing Lists,
This is primarily an FYI and an RFC. I have some code, included below,
that could be dropped into a *.ko for the 6.1.X kernel, but really this
mail is to query about ideas for acceptable upstream changes.
Thank you ahead of time
Exynos7870 is an arm64 SoC manufactured by Samsung and announced in
2016. It is present in multiple mid-range Samsung phones and tablets.
Add basic devicetree support for the SoC, which includes CMUs, pin
controllers, I2C, UART, DW-MMC, and USB-DRD.
