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. * tag 'imx-fixes-3.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: (460 commits) ARM: imx: Fix the removal of CONFIG_SPI option ARM: imx: clk-vf610: define PLL's clock tree + Linux 3.18-rc3 Signed-off-by: Olof Johansson <olof@lixom.net>
