Yes, it depends on patch 2 of the series (which is based on v3.14-rc4).
This is my mistake, the title of patch 2 is wrong:
ARM: STi: add pinctrl support for the STiH407 SoC

Should be:

pinctrl: st: add pinctrl support for the STiH407 SoC

I will resend the pinctrl patches rebased on your tree.

Thanks,
