Merge tag 'imx-fixes-3.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes

Merge "ARM: imx: fixes for 3.18, 2nd round" from Shawn Guo:

"This is the second round of i.MX fixes for 3.18.  The clk-vf610 fix is
relatively big, because it needs some adaption to the change made by
offending commit dc4805c2e78b (ARM: imx: remove ENABLE and BYPASS bits
from clk-pllv3 driver).  And it should have been sent to you for earlier
-rc inclusion, but unfortunately it got delayed for some time because
Stefan wasn't aware of my email address change."

The i.MX fixes for 3.18, 2nd round:
 - Fix a regression on Vybrid platform which is caused by commit
   dc4805c2e78b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3
   driver), and results in a missing configuration on PLL clocks.
 - Fix a regression with i.MX defconfig files where CONFIG_SPI option
   gets lost accidentally.
