    clocksource: sh_tmu: Document r8a7779 binding · fb0eee2f
    Simon Horman authored
    In general Renesas hardware is not documented to the extent
    where the relationship between IP blocks on different SoCs can be assumed
    although they may appear to operate the same way. Furthermore the
    documentation typically does not specify a version for individual
    IP blocks. For these reasons a convention of using the SoC name in place
    of a version and providing SoC-specific compat strings has been adopted.
    
    Although not universally liked this convention is used in the bindings
    for a number of drivers for Renesas hardware. The purpose of this patch is
    to update the Renesas R-Car Timer Unit (TMU) driver to follow this
    convention.

    * I plan to follow up with a patch patch to use the new binding in the
      dtsi files for the r8a7779 SoC.
    commit 471269b790aec03385dc4fb127ed7094ff83c16d
    
    v2
    * Suggestions by Mark Rutland and Sergei Shtylyov
      - Compatible strings should be "one or more" not "one" of those listed
      - Describe the generic binding as covering any MTU2 device
      - Re-order compat strings from most to least specific
    
    v3
    * Suggested by Laurent Pinchart
      - Reword in keeping with a similar though more extensive patch for CMT
