[PATCH 00/17] Expand Aspeed AST2500 Support

[Maxim Sloyko]

This series expands support for Aspeed AST2500 SoC, commonly used as
Board Management Controller in many servers, to the point where it can
actually be useful.

The main goal of this series is I2C and Network drivers, the rest are
either cleanups or supporting patches. Most notable among them is
addition of Watchdog Uclass, so that watchdog drivers can now use Driver
Model.

One notable thing that is *missing* from this series is Device Tree
configuration for I2C driver. The Linux Kernel I2C driver is still under
review and it may affect the details of how devices need to be
configured in the Device Tree. So, I decided to wait until it will show
up in Linux Kernel DT and then pull it into U-Boot.


Maxim Sloyko (17):
  aspeed: Update ast2500 Device Tree
  dm: Simple Watchdog uclass
  aspeed: Watchdog Timer Driver
  aspeed: Make SCU lock/unlock functions part of SCU API
  aspeed: Reset Driver
  aspeed: Device Tree configuration for Reset Driver
  aspeed: Refactor AST2500 RAM Driver and Sysreset Driver
  aspeed: AST2500 Pinctrl Driver
  aspeed: Enable Pinctrl Driver in AST2500 EVB
  aspeed: Add P-Bus clock in ast2500 clock driver
  aspeed: Add I2C Driver
  aspeed: Enable I2C in EVB defconfig
  aspeed: Add support for Clocks needed by MACs
  aspeed: Refactor SCU to use consistent mask & shift
  aspeed: Cleanup ast2500-u-boot.dtsi Device Tree
  aspeed: Add AST2500/AST2400 compatible NIC Driver
  aspeed: Network Driver configuration for EVB
