pinctrl: aspeed: Read and write bits in LPC and GFX controllers

2017-02-05T23:35:04+00:00

The System Control Unit IP block in the Aspeed SoCs is typically where the pinmux configuration is found, but not always. A number of pins depend on state in one of LPC Host Control (LHC) or SoC Display Controller (GFX) IP blocks, so the Aspeed pinmux drivers should have the means to adjust these as necessary. We use syscon to cast a regmap over the GFX and LPC blocks, which is used as an arbitration layer between the relevant driver and the pinctrl subsystem. The regmaps are then exposed to the SoC-specific pinctrl drivers by phandles in the devicetree, and are selected during a mux request by querying a new 'ip' member in struct aspeed_sig_desc.

dt-bindings: Add Aspeed LPC Control bindings

2017-01-16T00:19:02+00:00

The ast2500 and ast2400 BMC SoCs contain a LPC (Low Pin Count) bus for communication with a host CPU. These bindings describe the hardware that controls the bus. Signed-off-by: Cyril Bur Signed-off-by: Joel Stanley

ARM: dts: aspeed: restore labels of the flash modules

2016-11-28T09:03:04+00:00

commit e62c7f111755 ("ARM: dts: aspeed: fix flash module device nodes") removed the 'label' property under the flash module device nodes because of the lack of support in mainline. This change broke a number of OpenBMC user space tools. let's revert the label change. Signed-off-by: Cédric Le Goater Signed-off-by: Joel Stanley

ipmi: add an Aspeed BT IPMI BMC driver

mtd: spi-nor: Add SPI memory controllers for Aspeed SoCs

2016-10-21T06:13:57+00:00

This driver adds mtd support for spi-nor attached to either or both of the Firmware Memory Controller or the SPI Flash Controller (AST2400 only). The SMC controllers on the Aspeed AST2500 SoC are very similar to the ones found on the AST2400. The differences are on the number of supported flash modules and their default mappings in the SoC address space. The Aspeed AST2500 has one SPI controller for the BMC firmware and two for the host firmware. All controllers have now the same set of registers compatible with the AST2400 FMC controller and the legacy 'SMC' controller is fully gone. Based on previous work from Milton D.
