2022-04-22ARM: dts: keystone: Fix missing fallback and case in SPI NOR node compatibleKrzysztof Kozlowski1-1/+1
Vendor prefix in compatible should be lower-case and the jedec,spi-nor should be used as fallback, according to the bindings.

2022-04-22ARM: dts: keystone: Align SPI NOR node name with dtschemaKrzysztof Kozlowski1-1/+1
The node names should be generic and SPI NOR dtschema expects "flash".

2017-12-17ARM: dts: keystone*: Use a single soc0 instanceNishanth Menon1-2/+2
Provide a soc0 node and reference the same to simplify dts. This also resolves the following warnings when built with W=1: arch/arm/boot/dts/keystone-k2hk-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2l-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2e-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2g-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2g-ice.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name NOTE: Though we can reformat files by reducing 1 level of indent due to the use of soc0 phandle, we omit that change to prevent un-necessary churn in code base.

2017-12-03ARM: dts: keystone: Add generic compatible string for I2C EEPROMJavier Martinez Canillas1-1/+1
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

2017-07-31ARM: dts: keystone-k2e-evm: Add and enable DSP CMA memory poolSam Nelson1-0/+18
A CMA memory pool reserved memory node is added, and is attached to the DSP node through the 'memory-region' property on the K2E EVM board. This area will be used for allocating virtio rings and buffers. This node allows the DSP Memory Protection and Address Extension (MPAX) module to be configured properly for the DSP processor, and matches the values used on the other Keystone 2 boards for software compatibility. The reserved memory node and the user DSP node are also marked okay to enable the DSP on the 66AK2E EVM board.

2016-08-31ARM: dts: keystone: specify usb mode explicitlyGrygorii Strashko1-2/+10
The USB OTG mode is not supported by Kestone 2 devices, as result, the USB devices enumeration and detection will not work properly when kernel is built with CONFIG_USB_DWC3_DUAL_ROLE=y (default for multi platform build): - it's required to load gadget drivers manually to make host mode work and this confuses current Keystone 2 users - device mode is not working, because port can't detect and switch to peripheral/host mode dynamically. Hence, specify usb mode explicitly in DT: usb0 = "host" for all KS2 devices and usb1 = "peripheral" for K2E.

2016-04-13ARM: dts: k2*: Rename the k2* files to keystone-k2* filesNishanth Menon1-0/+154
As reported in [1], rename the k2* dts files to keystone-* files this will force consistency throughout. Script for the same (and hand modified for Makefile and MAINTAINERS files): for i in arch/arm/boot/dts/k2* do b=`basename $i`; git mv $i arch/arm/boot/dts/keystone-$b; sed -i -e "s/$b/keystone-$b/g" arch/arm/boot/dts/*[si] done NOTE: bootloaders that depend on older dtb names will need to be updated as well.
