i.MX defconfig update for 5.5:
 - Enable i.MX7ULP watchdog, DA9052 touch and USB configfs support
   in imx_v6_v7_defconfig.

   defconfig.
 - Built i.MX8QXP SCU key driver as module in arm64 defconfig.
 - Change AT803X Ethernet PHY driver from module to built-in, so that
   we can boot i.MX8MM EVK board with rootfs on NFS.

LX2160A TMU support for 5.5:
 - Add TMU (Thermal Monitoring Unit) device node to enable thermal
   support on LX2160A SoC.

i.MX arm64 device tree changes for 5.5:
 - Add the initial support for a new arm64 family SoC from NXP:
   S32V234 ("Treerunner") vision microprocessors which are targeted for
   high-performance, computationally intensive vision and sensor fusion
   applications that require automotive safety levels.
 - New board support: i.MX8MN LPDDR4 EVK, i.MX8QXP Colibri and
   S32V234 EVB.
 - A series of patch from Andrey Smirnov to improve zii-ultra support by
   fixing regulator and adding accelerometer, switch watchdog.
 - Add system counter device and enable cpuidle support for i.MX8MN.
 - Move usdhc clocks assignment from SoC to board level DTS for
   i.MX8 based boards.
 - Add PCA6416 on I2C3 bus for imx8mm-evk, and enable SCU key for
   imx8qxp-mek board.
 - Enable GPU passive throttling on i.MX8MQ SoC, and add DDR PMU device
   for i.MX8MN.
 - A series from Fabio Estevam to fix DTC W=1 warnings for LS1028A device.
 - Update the clock providers for the Mali DP500 and '#clock-cells' of
   DPCLK node for LS1028A SoC.
 - Misc small updates on various boards.

i.MX device tree changes for 5.5:
 - New board support: Netronix E60K02 and Kobo Clara HD, Kontron N6311
   and N6411, OPOS6UL and OPOS6ULDev.
 - Correct speed grading fuse settings and add opp-suspend property for
   i.MX7D device tree.
 - Move usdhc clocks assignment from SoC to board level DTS for imx7ulp,
   and use APLL_PFD1 as usdhc's clock source on imx7ulp-evk board.
 - Add missing cooling device properties for CPUs for i.MX6/7 SoCs.
 - Add sensor GPIO regulator and assign power supplies for magnetometer
   for imx6ul-14x14-evk board.
 - Replace "simple-bus" with "simple-mfd" for ANATOP device for i.MX6/7
   SoCs.
 - Fix DTC W=1 warnings by not using simple-audio-card,dai-link on
   imx6qdl-gw551x and imx6q-gw54xx board.
 - Move to use DRM bindings for the Seiko 43WVF1G panel on imx53-qsb.
 - A series from Frieder Schrempf to support more i.MX6UL/ULL-based SoMs
   and boards from Kontron Electronics GmbH.
 - A few patches from Michal Vokáč to enable more devices support on
   imx6dl-yapp4 board.
 - A patch series from Philippe Schenker to improve i.MX6/7 Apalis and
   Colibri board support.
 - A patch series from Sébastien Szymanski to update i.MX6 APF6/APF6Dev
   device tree with more devices added and adopting DRM bindings for
   display.
 - Random improvements, clean-up and device additions on various boards.

i.MX dt-bindings update for 5.5:
 - Update fsl.yaml to include DT compatibles for following devices:
   Kobo Clara HD, i.MX8MN LPDDR4 EVK, S32V234-EVB, Kontron i.MX6UL/ULL
   boards, Toradex apalis/colibri boards, Variscite and Armadeus i.MX6
   boards.

i.MX SoC update for 5.5:
 - Add arm64 Kconfig option for the NXP S32 platform.
 - Drop imx_anatop_usb_chrg_detect_disable() function which becomes
   unneeded, since all the necessary charger setup is done by the USB
   PHY driver now.
 - Add serial number support for i.MX6/7 SoCs by reading 64-bit SoC
   unique ID from OCOTP block.
 - Replace i.MX machine specific coherency exit implementation using
   the generic v7_exit_coherency_flush() function.

i.MX drivers update for 5.5:
 - Skip return check for those SCU firmware APIs that are defined as
   void function in firmware.
 - Use established serial_number attribute instead of custom one to show
   SoC's unique ID for i.MX8 SoC drivers.
 - Read i.MX8MQ SOC revision from TF-A which parses ROM and exposes the
   value through a SMC call. This improves the situation that SOC
   revision reports 'unknown' on some older revisions.
 - Add a check and warn on unexpected SCU RX to avoid potential stack
   corruption in imx-scu driver.
 - Fix a sparse warning in imx-scu-irq driver by adding missing header.
 - Remove an unneeded call to devm_of_platform_populate() from imx-dsp
   driver.

i.MX clock changes for 5.5:
 - Make 1443X/1416X PLL clock structure common for reusing among i.MX8
   SoCs.
 - A couple of imx7ulp clock multiplexer option corrections.
 - Drop IMX7ULP_CLK_MIPI_PLL clock, as it's a MIPI DSI local clock and
   shouldn't be used externally.
 - Add VIDEO2_PLL clock for imx8mq which is needed by DCSS when high
   resolutions are used.
 - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs.
 - Register SYS_PLL1 and SYS_PLL2 as fixed clock rather than pll14xx
   type of clock.
 - Use imx_obtain_fixed_clk_hw() to simplify i.MX6/7/8 clock driver code
   a little bit.
 - One cosmetic change on clk-pll14xx code to make variables static.
