    Standardise header guards across codebase · c3cf06f1
    Antonio Nino Diaz authored
    
    All identifiers, regardless of use, that start with two underscores are
    reserved. This means they can't be used in header guards.
    
    The style that this project is now to use the full name of the file in
    capital letters followed by 'H'. For example, for a file called
    "uart_example.h", the header guard is UART_EXAMPLE_H.
    
    The exceptions are files that are imported from other projects:
    
    - CryptoCell driver
    - dt-bindings folders
    - zlib headers
