• patch device tree with serial number, product id and revision properties to make that information available in Linux
• configure PMIC for suspend/sleep modes
• fix writing of first firmware copy
• print warning about upcoming NAND change:
  WARNING: This module uses an early tapeout/stepping of the i.MX 7 SoC which suffers a NAND flash issue requiring a software workaround. This U-Boot version still implements this workaround, but future U-Boot versions provided by Toradex will not use the workaround anymore. You must use a newer Colibri iMX7 (V1.1B or later) to use future software versions. For evaluation and testing purposes it will be possible to keep the current U-Boot and only update the kernel and root filesystem.
• Linux kernel:
• merge changes from latest NXP release 4.1.15_1.2.0_ga

• control BL_ON (using the PWM backlight drivers enable-gpios property)
• add PWM polarity support (#18164)
• disable internal RTC on Colibri iMX7 Solo (currently not functioning)
• enable USB OTG device/host detection on USBC (#19050)
• improve pinmuxing (disable conflicting pinmux on multiplexed pins and fix conflicting pinmux on pins which are pulled on carrier board)
• keep 240MHz system clock on which allows to start the Cortex-M4 core via JTAG
• synchronize defconfig (#19484)
