Re: [PATCH v2 1/3] dt-bindings: iio: adc: convert rockchip saradc bindings to yaml

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Jonathan,

Originally I just followed 'rk3288.dtsi' till I saw someone posting a
patch with only 'arm-gic.h' included that made me to have a closer look
at it.
Due to the #ifndef construction it doesn't rise any warnings I think.
Apply the version that fits best.

Kind regards,

Johan Jonker



#ifndef _DT_BINDINGS_INTERRUPT_CONTROLLER_IRQ_H
#define _DT_BINDINGS_INTERRUPT_CONTROLLER_IRQ_H
[..]
#endif

Something else...
With 2 examples it gives a warning that 2 identical defines are used.
Yaml doesn't separately compile the examples. Must use the same SoC.

This doesn't work. One example for rk3288 and one for rk3399.
examples:
  - |
    #include <dt-bindings/clock/rk3288-cru.h>
    #include <dt-bindings/interrupt-controller/arm-gic.h>
[..]
  - |
    #include <dt-bindings/clock/rk3399-cru.h>
    #include <dt-bindings/interrupt-controller/arm-gic.h>
[..]
