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.
