Merge tag 'regmap-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown: "Another busy release for regmap with the second half of the maple tree register cache implementation, there's some smaller optimisations that could be done but this should now be able to replace the rbtree cache for most devices. We also had a followup from Aidan MacDonald's refactoring of some of the regmap-irq interfaces, the conversion is complete so the old interfaces are removed. This means that even with the new features for the maple tree cache we'd have a nice negative diffstat were it not for the addition of a bunch more KUnit coverage. There's one GPIO patch in here, it was a dependency for a cleanup of an API in the regmap-irq code for which the gpio-104-dio-48e driver was the only user. Highlights: - The maple tree cache can now load in default values more efficiently, and is capabale of syncing multiple registers in a single write during cache sync - More KUnit coverage, including some coverage for raw I/O and a dummy RAM backed cache to support it - Removal of several old interfaces in regmap-irq now all users have been modernised" * tag 'regmap-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (23 commits) regmap: Allow reads from write only registers with the flat cache regmap: Drop early readability check regmap: Check for register readability before checking cache during read regmap: Add test to make sure we don't sync to read only registers regmap: Add a test case for write only registers regmap: Add test that writes to write only registers are prevented regmap: Add debugfs file for forcing field writes regmap: Don't check for changes in regcache_set_val() regmap: maple: Implement block sync for the maple tree cache regmap: Provide basic KUnit coverage for the raw register I/O regmap: Provide a ram backed regmap with raw support regmap: Add missing cache_only checks regmap: regmap-irq: Move handle_post_irq to before pm_runtime_put regmap: Load register defaults in blocks rather than register by register regmap: mmio: Allow passing an empty config->reg_stride regmap-irq: Drop backward compatibility for inverted mask/unmask regmap-irq: Minor adjustments to .handle_mask_sync() regmap-irq: Remove support for not_fixed_stride regmap-irq: Remove type registers regmap-irq: Remove virtual registers ...
