Subject: [PATCH v5 00/12] aspeed: Add SCU interrupt controller and XDMA engine drivers
Date: Thu, 9 Jan 2020 14:58:51 -0600 [thread overview]
Message-ID: <20200109205903.27036-1-eajames@linux.ibm.com> (raw)
This series first adds a driver to control the interrupt controller provided by
the System Control Unit (SCU) on the AST2500 and AST2600 SOCs. The interrupts
made available are necessary for the control of the XDMA engine embedded in the
same Aspeed SOCs.
This series then adds a driver to control the XDMA engine. This driver was
previously sent to the list without support for the AST2600, and has been
refactored significantly to enable that support. The XDMA engine performs
automatic DMA operations between the Aspeed SOC (acting as a BMC) and a host
processor.
Changes since v4:
- Fix dts documentation example for XDMA
- Add errno in warning for SCU failure in XDMA PCIe config
- Add a check for in_reset before proceeding in O_NONBLOCK case
- Add comments to memory sizes in the witherspoon/tacoma XDMA dts entries
Changes since v3:
- See individual patches; just clean-up items
Changes since v2:
- See individual patches
- Drop rainier dts patch
- In summary, remove references to VGA memory as the XDMA driver doesn't care
where it is. Remove SDRAM controller reference. Move user reset
functionality to a separate patch and make it an ioctl.
Changes since v1:
- See individual patches
- In summary, first the irqchip driver switched to use the parent SCU regmap
rather than iomapping it's register. Secondly, the XDMA initialization
switched to use properties from the device tree rather than dynamically
calculate memory spaces, and system config.
