[U-Boot] [PATCH 00/10] Enable i.MX8MM EVK BD71837 pmic

[Peng Fan]

This patch is to enable BD71837 pmic for i.MX8MM EVK.
Two i.MX8MQ patches are also included.

Peng Fan (10):
  imx8m: imx8mq: get chip rev for B1 revision
  imx8m: clock: improve irq response latency
  imx: imx8mq: add init_nand_clk
  imx: spl: implement spl_boot_mode for i.MX7/8/8M
  dt-bindings: import usb pd
  arm: dts: imx8mm: sync dts from Linux Kernel
  pmic: bd71837: drop DEBUG macro
  power: pmic: Kconfig: add CONFIG_SPL_DM_PMIC_BD71837
  imx8m: evk: spl: probe clk in spl early stage
  imx8mm: evk: enable bd71837 pmic

[U-Boot] [PATCH 09/10] imx8m: evk: spl: probe clk in spl early stage

[Peng Fan]

We are going to add i2c pmic support before dram could be used.
So we need enable clk driver earlier, so use spl_early_init
and move clock controller probe eariler to board_init_f.
