Pull "i.MX device tree update with new clock for 4.17" from Shawn Guo:

 - Add CAAM and Keypad device node for i.MX7S/D SoC device tree.
 - Add clock support for i.MX7 SNVS RTC device.

* tag 'imx-dt-newclk-4.17' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
  ARM: dts: imx7s: add Keypad Port module
  ARM: dts: imx7s: add CAAM device node
  ARM: dts: imx7s: add snvs rtc clock
  clk: imx: imx7d: add the Keypad Port module clock
  clk: imx7d: add CAAM clock
  clk: imx: imx7d: add the snvs clock
