f5edb0d86d clk: imx: imx8mm: Fix the first root clock in imx8mm_ahb_sels[]
The 24MHz oscillator clock is referenced by "clock-osc-24m" and not
"osc_24m".

Modifed from Linux Kernel 5.3.0-rc1, drop some entries
that not used in U-Boot and adapt to U-Boot CCF style.

727fa4539c clk: Add support for I2C clocks on NXP's imx6q SoC which use CCF
This change adds support for I2C clock modeled in CCF. This code intention
is to only enable those clocks in the I2C driver with default settings.
For that reason the "busy" versions of clocks reuse the generic approach
and would need to be updated when one wants to adjust the I2C clock
frequency in U-Boot.

1d7993d1d0 clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)
This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.

One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.

If needed, the code can be extended to support the "set" part of the clock
management.

16f8b84917 clk: imx8qm: fix usdhc2 clocks
Trying to bring up uSDHC2 the following error message was observed:

MMC:   imx8_clk_set_rate(Invalid clk ID #60)
imx8_clk_set_rate(Invalid clk ID #60)
usdhc@5b030000 - probe failed: -22

This commit fixes this by properly setting resp. clocks.

98c63a7840 clk: imx8: split code into common and soc specific part
To make it easy to add new clk driver for i.MX8, split
the code into common part and SoC specific part.

Make the get/set/enable non static and introduce a num_clks for
soc_clk_dump, because the arrays are moved to clk-imx8qxp.c.
