[U-Boot] [PATCH V3 0/4] Prepare i.MX8MM clk

[Peng Fan]

V3:
 2/4: Fix RST/BYPASS seq issue to avoid glitch
 4/4: ARM clk not use 24M for switch, use pll2_500m  Add R-b/A-b tag
      Fix pll gate shift bit.

V2:
 2/4: fix MASK/SHIFT usage

This is to support i.MX8MM clk driver.
i.MX8MM use similar clock design as i.MX7D, but it has use
different PLL, so we need to add pll14xx driver. And to simplify
the clock usage, import the composite clk driver from Linux Kernel,
then we could have simple clk tree.

This is to split the previous patchset
https://github.com/MrVan/u-boot/commits/imx8mmn-ccf
for i.MX8MM/N support

There are some checkpatch warnings that not addressed,
because import from Linux Kernel.

Peng Fan (4):
  clk: imx: add Kconfig entry for i.MX8MM
  clk: imx: add pll14xx driver
  clk: imx: add i.MX8M composite clk support
  clk: imx: add i.MX8MM clk driver
