2018-08-28Documentation: dt: keystone: ti-sci: Add optional host-id parameterNishanth Menon1-0/+4
Texas Instrument's System Control Interface (TISCI) permits the ability for OSs running in virtual machines to be able to independently communicate with the firmware without the need going through an hypervisor. The "host-id" in effect is the hardware representation of the host (example: VMs locked to a core) as identified to the System Controller. Hypervisors can either fill in appropriate host-ids in dt used for each VM instance OR may use prebuilt blobs where the host-ids are pre-populated, as appropriate for the OS running in the VMs. This is introduced as an optional parameter to maintain consistency with legacy device tree blobs.

Texas Instrument's System Control Interface (TI-SCI) Message Protocol is used in Texas Instrument's System on Chip (SoC) such as those in newer SoCs in the keystone processor family starting with K2G. This message protocol is used to communicate between various compute or processing entities (such as ARM, DSP etc.) with a central system controller entity. TI-SCI message protocol provides support for management of various hardware entities within the SoC.

2015-10-06Documentation: dt: keystone: provide SoC specific compatible flagsNishanth Menon1-3/+17
Keystone2 devices are used on more platforms than just Texas Instruments reference evaluation platforms called EVMs. Providing a generic compatible "ti,keystone" is not sufficient to differentiate various SoC definitions possible on various platforms for the following reasons: a) Userspace applications have no way of knowing which SoC they are functioning, providing the compatible matches provide a mechanism for them to enable SoC specific functionality. Such userspace applications are typically automated test framework or SoC custom hardware acceleration entitlement from a common file system. b) Provides an accurate hardware description. This allows SoC specific logic to be run time handled based on of_machine_is_compatible("ti,k2hk") or as needed for the dependent processor instead of needing to use board dependent compatibles that are needed now. Hence, provide compatible matches for each SoC in the Keystone family.

2014-03-21ARM: dts: keystone: use common "ti,keystone" compatible instead of -evmIvan Khoronzhuk1-3/+3
As suggested by Olof Johansson at http://www.spinics.net/lists/arm-kernel/msg314009.html. It be better just keeping a "ti,keystone" top-level compatible and just using that to probe. If so we don't have to touch the file for new boards in the future. So use common "ti,keystone" compatible in keystone.c for all boards.
