Documentation/process/license-rules.rst and checkpatch expect the SPDX identifier syntax for multiple licenses to use capital "OR". Correct it to keep consistent format and avoid copy-paste issues. Correct also the format // -> .* in few Allwinner binding headers as pointed out by checkpatch: WARNING: Improper SPDX comment style for 'include/dt-bindings/reset/sun50i-h6-ccu.h', please use '/*' instead Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Stephen Boyd <sboyd@kernel.org> Link: https://lore.kernel.org/r/20230823084540.112602-1-krzysztof.kozlowski@linaro.org Signed-off-by: Rob Herring <robh@kernel.org>

Arm Trace Buffer Extension (TRBE) is a per CPU component
|
|
for storing trace generated on the CPU to memory. It is
|
|
accessed via CPU system registers. The software can verify
|
|
if it is permitted to use the component by checking the
|
|
TRBIDR register.

Exactly 1 PPI must be listed. For heterogeneous systems where

TRBE is only supported on a subset of the CPUs, please consult

the arm,gic-v3 binding for details on describing a PPI partition.
