v0 [Kazuya Mizuguchi]

v1 [Simon Horman]
* updated p_clk to s3d4_clk
* moved to clock node
* updated patch subject
* use R8A7795 as prefix for clock defines

v2 [Simon Horman]
* As suggested by Geert Uytterhoeven
  - Use s3d2_clk use it instead: it is now already present in the base
    of this series
  - Use R8A7795_CLK_ETHERAVB instead of R8A7795_CLK_AVB
* As suggested by Kuninori Morimoto and Sergei Shtylyov
  - Use "clock-indices" instead of "renesas,clock-indices"

v3 [Simon Horman]
* As suggested by Geert Uytterhoeven
  - Name clock "etheravb"
* Add Ack

* No change

TODO:
* Drop clock-output-names from mstp8_clks ?
