| Nordic Split Channels |
| |
| Some of Nordic's peripherals support split ownership feature that allows to |
| be used by independent owners. As an example the configuration of the |
| Global Real Time Counter (GRTC) is shown below: |
| owned-channels = <0 1 2 3 4 5 6 7 8 9 10 11>; |
| child-owned-channels = <7 8 9 10 11>; |
| |
| Which means that channels 0-11 will be assigned to the particular CPU. |
| Other CPUs cannot use those and another set must be defined for them. |
| In addition, `child-owned-channels` property allows to use channels |
| 7-11 only by child subprocessor. If the CPU you're configuring has no |
| subprocessor(s) assigned, the `child-owned-channels` property |
| should not be defined. |
| |
| properties: |
| owned-channels: |
| type: array |
| description: | |
| List of channels in a split-ownership peripheral that are to be owned |
| for use by the compiled CPU. |
| |
| nonsecure-channels: |
| type: array |
| description: | |
| List of channels in a split-ownership, split-security peripheral that |
| are to be configured as nonsecure. In Trustzone systems, this property |
| is only evaluated for secure peripherals, as nonsecure channels are |
| implicitly specified through the owned-channels property. This property |
| is ignored in non-Trustzone systems. |
| |
| child-owned-channels: |
| type: array |
| description: | |
| List of channels in a split-ownership peripheral that are officially |
| owned by the compiled CPU but intended to be used by its child |
| subprocessor(s). |
