[PATCH 0/2] clk: renesas: r8a779a0: Add clocks to support thermal

[Niklas Söderlund]

Hello,

This series aims to add enough clocks to enable proper operation of the 
thermal IP block for V3U. The series have been tested on target together 
with other thermal enablement patches to prove operation of thermal.

Niklas Söderlund (2):
  clk: renesas: r8a779a0: Add CP clock
  clk: renesas: r8a779a0: Add THS/TSC clock

The R-Car V3U Series User's Manual calls this clock "tsc", and states its
parent is "cl16m".
