Merge tag 'at91-ab-4.10-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux into next/drivers
Drivers for 4.10:
- few fixes for the memory drivers
- minimal security module driver
- support for the Secure SRAM
* tag 'at91-ab-4.10-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux:
misc: sram: add Atmel securam support
misc: sram: document new compatible
ARM: at91: add secumod register definitions
Documentation: dt: atmel-at91: Document secumod bindings
memory: atmel-sdramc: use builtin_platform_driver to simplify the code
memory: atmel-ebi: fix return value check in at91_ebi_dev_disable()
