[DEBUG 0/5] ARM: shmobile: r8a7791: MSTP debug code

[Geert Uytterhoeven]

	Hi all,

This series contains the MSTP debug code I used for investigation and
development. It is _not_ meant to be applied!

  - [1/5] ARM: shmobile: r8a7791: Disable MSTP clocks
  - [2/5] r8a7791: show MSTP clock status during boot-up
  - [3/5] sh/cpg: Monitor MSTP clock enable/disable
  - [4/5] clk/mstp: Monitor MSTP clock enable/disable
  - [5/5] r8a7791: show MSTP clock status in /proc/cpuinfo

People working on other drivers (e.g. sound, SDHI, USB, ...) may want to
apply patch 1, to check if their driver correctly enables all needed clocks.
If deemed useful, this patch (or a less verbose version) could be applied,
though.

Patches 2-5 can be used to check which clocks are enabled at kernel start
time, to check when clocks are enabled/disabled, and to check which clocks
are enabled at an arbitrary moment in time.

All code should be multi-platform safe. I used it in a kernel that supports
and runs on both Koelsch and BeagleBone Black.

Have fun! ;-)

Gr{oetje,eeting}s,
