V2:
 2/4: fix MASK/SHIFT usage
 4/4: ARM clk not use 24M for switch, use pll2_500m
 Add R-b/A-b tag

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
