Hi, This series adds clock driver for Clock Generation Unit(CGU) of Lightning Mountain(LGM) SoC. Patch 1 adds bindings document & include file for CGU. Patch 2 adds common clock framework based clock driver for CGU. These patches are baselined upon Linux 5.6-rc1 at below Git link: git git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git v7: - Fix a mistake in comments explaining structure fields. v6: - Resolve Kconfig dependencies issues (Randy Dunlap) v5: - Address review concerns - mainly below mentioned. (Stephen Boyd) - Improve commit message, add COMPILE_TEST in KConfig dependency. - Remove unused header include files, drop unnecessary casts. - Switch to using readl_poll_timeout() instead of implementing timeout routine. - Avoid using small functions which are called just once. Inline them or remove them. - const static --> static const - Fix coding style/convention related review concerns. - Use __iomem for all IO addresses variables. - Consolidate clk_enable & clk_disable ops into a common clk_enable_disable routine to avoid redundant code. - Remove unnecessary dev pointers for clk data structures. - Redesign code to use new way of specifying clk_parents i.e. use clk_parent_data.fw_name instead of older parent_name strings. - Switch from raw_spin_locks() to normal spin_locks() and realign locking. - Drop __initconst, __init, __refdata. - Reorder patch series - make dt-binding patch as first patch. - Add pointer to include file in dt-bindings document. - Remove CLK_IS_CRITICAL flag for clks for which IGNORE_UNUSED flag is enough. Add comments for clks which are marked as CRITICAL. - Fix $id path in dt-bindings - drop bindings. (Rob Herring). - Add Reviewed-by tag from Rob Herring. Thanks Rob. v4: - Add drivers/clk/x86/Kconfig file which got missed in v3 by mistake. v3: - Address review concerns: Add Kconfig entry in x86 folder instead of modifying clk/Kconfig. (Andy Shevchenko) Fix coding style/convention related concerns. (Andy Shevchenko) Improve description, licensing info, rename node name correctly in dt bindings document & remove CLK_NR_CLKS from dt-bindings header file. (Stephen Boyd) Fix a build warning reported by kbuild test robot & Nathan Chancellor - Add few new clocks & rename few existing clocks. - Add more ops for ddiv & divider clk_ops. - Fix few minor bugs. - Use CLK_IS_CRITICAL flag for clocks which shall never be disabled. 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.
