Subject: [PATCH v2 0/2] clk: intel: Add a new driver for a new clock controller IP

Hi,

This series adds clock driver for Clock Generation Unit(CGU) of
Lightning Mountain(LGM) SoC.

Patch 1 adds common clock framework based clock driver for CGU.
Patch 2 adds bindings document & include file for CGU.

These patches are baselined upon Linux 5.5-rc1 at below Git link:
git git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git

v2:
- Move the driver to x86 folder.
- Remove syscon usage.
- Remove regmap based access. Use direct readl()/write() instead. Add spinlocks.
- Change all enum values to capitals.
- Rename all data structures & functions from intel_* to lgm_*.
- Remove multiple header files. Keep only one header file.
- Make probe fail when any of the clk/pll registration fails.
- Fix few bugs with clk_init_data assignement.
- Address review concerns for code quality/style/convention.

v1:
- Initial version.
