The main difference from the previous generation is that the control logic has been updated to support per-pin control, allowing each pin to have its own 32-bit register for configuring value, direction, interrupt type, and more. This patch serial also add low-level operations (llops) to abstract the register access for GPIO registers and the coprocessor request/release in gpio-aspeed.c making it easier to extend the driver to support different hardware register layouts. Changes since v1: - Merge the gpio-aspeed-g7.c into the gpio-aspeed.c. - Create the llops in gpio-aspeed.c for flexibility.
