clocksource: sh_tmu: Document r8a7779 binding
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.
