[PATCH v2 2/3] reset: simple: Enable for ASPEED systems

From: Joel Stanley
Date: Mon Feb 19 2018 - 20:44:06 EST


ASPEED BMC SoCs have a reset controller in the LPC IP that can be
controlled using this driver to release the UARTs from reset.

No special configuration is required, so only the compatible string is
added.

This enables a simple reset controller driver for reset lines that
that can be asserted and deasserted by toggling bits in a contiguous,
exclusive register space.

- Currently this driver supports Altera SoCFPGAs, the RCC reset
- controller in STM32 MCUs, Allwinner SoCs, and ZTE's zx2967 family.
