2022-07-05ARM: dts: aspeed: align gpio-key node names with dtschemaKrzysztof Kozlowski1-2/+2
The node names should be generic and DT schema expects certain pattern (e.g. with key/button/switch). Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20220616005333.18491-36-krzysztof.kozlowski@linaro.org
2021-06-03ARM: dts: aspeed: Set earlycon boot argumentJoel Stanley1-1/+1
Most of the aspeed boards have copied the 'earlyprink' string in the bootargs. However, there's no earlyprink driver configured in the defconfigs, so this does nothing. A combination of setting stdout in the chosen node and adding earlycon to bootargs causes early serial output to appear early. This changes all boards to use this option. The console=ttyS4,115200 option is still required, as this is used by the run time uart driver.

2020-05-05ARM: dts: aspeed: zaius: Add gpio line namesAndrew Geissler1-4/+33
Name the GPIOs to help userspace work with them. The names describe the functionality the lines provide, not the net or ball name. This makes it easier to share userspace code across different systems and makes the use of the lines more obvious.

2019-11-01ARM: dts: aspeed: Add RCLK to MAC clocks for RMII interfacesAndrew Jeffery1-0/+3
We need to ungate RCLK on AST2500- and AST2600-based platforms for RMII to function. RMII interfaces are commonly used for NCSI. Signed-off-by: Andrew Jeffery <andrew@aj.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au>
2019-11-01ARM: dts: aspeed: Add "spi-max-frequency" propertyCédric Le Goater1-0/+2
Keep the FMC controller chips at a safe 50 MHz rate and use 100 MHz for the PNOR on the machines using a AST2500 SoC. Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: Andrew Jeffery <andrew@aj.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au>
2019-05-24ARM: dts: aspeed: zaius: fixed I2C bus numbers for pcie slotsRobert Lippert1-0/+40
The change to include ibm-power9-cfam.dtsi resulted in a renumbering of all of the I2C bus numbers behind the on-board muxes. This breaks some tools which have hardcoded the bus numbers. Add device tree aliases for the I2C buses routed through the PCIe slots so that they return to their former numbers before the cfam change.

2019-05-24ARM: dts: aspeed: Add Power9 and Power9 CFAM descriptionBenjamin Herrenschmidt1-0/+2
To be used by the OpenPower BMC machines. This provides proper chip IDs but also adds the various sub-devices necessary for the future OCC driver among other. All the added nodes comply with the existing upstream FSI bindings.

2018-06-12fsi/fsi-master-gpio: Add "no-gpio-delays" optionBenjamin Herrenschmidt1-0/+1
This adds support for an optional device-tree property that makes the driver skip all the delays around clocking the GPIOs and set it in the device-tree of common POWER9 based OpenPower platforms. This useful on chips like the AST2500 where the GPIO block is running at a fairly low clock frequency (25Mhz typically). In this case, the delays are unnecessary and due to the low precision of the timers, actually quite harmful in terms of performance.

Zaius is a POWER9 platform announced at OpenPOWER Summit 2016. This adds basic DTS support for its AST2500 BMC. This adds the device tree description for most upstream components. It is a squashed commit of all of the patches from the OpenBMC kernel tree.
