Merge tag 'imx-soc-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc

i.MX SoC update for 4.18:
 - A series from Bartosz to convert all i.MX plaform code using
   at24_platform_data to use at24 eeprom generic device properties.
 - Enable pinctrl driver support for i.MX6SLL SoC.
 - Clean up i.MX platform code using spi_imx platform data on outdated
   documentation and chip select array usage.

* tag 'imx-soc-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
  ARM: imx: select imx6sll pinctrl when imx6sll enabled
