[PATCH 00/20] Add i.MXRT family support

[Giulio Benetti]

This patchset add support for i.MXRT family starting from i.MXRT1050 SoC.
It provides:
- i.MXRT1050 SoC entry
- i.MXRT pinctrl driver
- i.MXRT serial driver tweaking
- i.MXRT sdram controller driver
- i.MXRT usdhc driver tweaking
- i.MXRT1050-evk initial support

It uses all DM clocks all around and it loads correctly a basic Linux zImage.

Giulio Benetti (20):
  armv7m: cache: add mmu_set_region_dcache_behaviour() stub for
    compatibility
  spl: fix entry_point equal to load_addr
  clk: imx: pllv3: register PLLV3 GENERIC and USB as 2 different clocks
  clk: imx: pllv3: set div_mask differently if PLLV3 is GENERIC or USB
  clk: imx: pllv3: add enable() support
  clk: imx: pllv3: add disable() support
  clk: imx: pllv3: add set_rate() support
  clk: imx: pllv3: add PLLV3_SYS support
  clk: imx: pllv3: add support for PLLV3_AV type
  clk: imx: pfd: add set_rate()
  clk: imx: add i.IMXRT1050 clk driver
  pinctrl: add i.MXRT driver
  ARM: dts: imxrt1050: add dtsi file
  serial_lpuart: add clock enable if CONFIG_CLK is defined
  serial_lpuart: add support for i.MXRT
  ram: add SDRAM driver for i.MXRT SoCs
  mmc: fsl_esdhc: make if(CONFIG_IS_ENABLED(CLK)) an #if statement
  mmc: fsl_esdhc: add compatible for fsl, imxrt-usdhc
  imx: Add basic support for the NXP IMXRT10xx SoC family
  imx: imxrt1050-evk: Add support for the NXP i.MXRT1050-EVK
