MICFIL IP is upgraded on i.MX93 platform. Add new registers and new bit
definition.
changes in v2:
- rename check_version to use_verid to make it more explicit
- rename fsl_micfil_check_version to fsl_micfil_use_verid

2.25.1
fsl_micfil_use_verid() can help to parse the version info in VERID and
PARAM registers. Since the two registers are added only on i.MX93
platform, a member flag called use_verid is introduced to soc data
structure which indicates acquiring MICFIL version.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
