Please refine the commit message a bit :-) . Something along

pclk_cpu needs to keep running and with the recent gpio clock
handling this is not always the case anymore. So add it to the list
of critical clocks.


and also please add "Linus Walleij <linus.walleij@linaro.org>" to the list of 
recipients. As the gpio clock handling change does go through his tree, the 
matching critical clock handling should also go through him.

Hi Heiko,

I merged yours and mine :-)


pclk_cpu needs to keep running because it is needed for devices like
the act8865 regulator but with the recent gpio clock handling this is
not always the case anymore. So add it to the list of critical clocks.

Hi Michael,


need to pick a bit more on your patch submission :-)

Please take a look for example at
http://lists.infradead.org/pipermail/linux-rockchip/2014-November/001043.html

on how a v2 submission needs to look like.

Specifically:
- In most cases not as a reply to a reply to another mail.
- Mail subject: [PATCH v2] clk: rockchip: add pclk_cpu to the list of rk3188 
critical clocks

no prose nor empty lines. If necessary such stuff could sit below the "---" 
which results in it not making it into the actuall commit message.

Here any prose-text you like to add.

Also, changelog:
changes in v2:
- adapt commit message
- add Linus Walleij to recipients, as the patch is related to the gpio clock
  change in the rockchip pinctrl driver it should go through his tree as well
