[PATCH v2 PART-RESEND 0/2] berlin sdhci clock clean up

[Jisheng Zhang]

Add or fix the optional clock property, then remove the CLK_IGNORE_UNUSED
flag for sdio clk(s).

This is a partialy resend of 
http://lists.infradead.org/pipermail/linux-arm-kernel/2015-October/379457.html

patch3, patch4 has been merged.

Since v1:
 - remove the "mmc: sdhci-pxav3: fix optional clock name" patch to not
   block the clock clean up patches, will send another separate patch
   after talking with HW people.

  ARM: dts: berlin: correct BG2Q's sdhci2 2nd clock
  ARM: dts: berlin: add 2nd clock for BG2Q sdhci0 and sdhci1

[PATCH v2 PART-RESEND 2/2] ARM: dts: berlin: add 2nd clock for BG2Q sdhci0 and sdhci1

[Jisheng Zhang]

Add the optional 2nd clock for BG2Q's sdhci0 and sdhci1. This would let the
clock be disabled during runtime pm, so saves power a bit.

Great! Really!

As they have been taken without my Acked-by, ignoring my request to
_not_ remove the CLK_IGNORE_UNUSED flags _before_ these two, the
remaining patches now become fixes.

Please resend the patches with a proper description what and why they
are fixes now.

Sebastian

Is this going to be resolved anytime soon?

If not, I am going to send a revert for the CLK_IGNORE_UNUSED patch
and we start this from the beginning.
