Hello.
Here's the set of 2 patches against the 'clk-next' branch of CLK group's
'linux.git' repo plus the R8A7743 CPG/MSSR patches just re-posted. They also
depend on the common R-Car Gen2 support patch. As the DT patches in the
R8A7745/SK-RZG1E board support series depend on the patch #1 of this series,
it might make sense to merge this patch to the 'renesas.git' repo as well...
[1/2] ARM: shmobile: r8a7745: add CPG clock index macros
[2/2] clk: renesas: cpg-mssr: add R8A7745 support

Add macros usable by the device tree sources to reference the R8A7745 CPG
clocks by index. The data comes from the table 7.2c in the revision 0.50
of the RZ/G Series User's Manual.

Add RZ/G1E (R8A7745) Clock Pulse Generator / Module Standby and Software
Reset support, using the CPG/MSSR driver core and the common R-Car Gen2
(and RZ/G) code.
Based on the proof-of-concept R8A7791 CPG/MSSR patch by Geert Uytterhoeven
<geert+renesas@glider.be>.

Add RZ/G1E (R8A7745) Clock Pulse Generator / Module Standby and Software
Reset support, using the CPG/MSSR driver core and the common R-Car Gen2
(and RZ/G) code.
Based on the proof-of-concept R8A7791 CPG/MSSR patch by Geert Uytterhoeven
<geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov-M4DtvfQ/ZS1MRgGoP+s0PdBPR1lH4CV8@public.gmane.org>
