Subject: Re: [PATCH] clk: rockchip: add pclk_cpu to the list of rk3188 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

no quotes of other mails, like the stuff below.
