Subject: [PATCH v8 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 bindings document & include file for CGU.
Patch 2 adds common clock framework based clock driver for CGU.
These patches are baselined upon Linux 5.7-rc1 at below Git link:
git git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git
v8:
- Rebase to linux 5.7-rc1.
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.
