Add support for Microchip Azurite DPLL/PTP/SyncE chip family that provides DPLL and PTP functionality. This series bring first part that adds the core functionality and basic DPLL support. The next part of the series will bring additional DPLL functionality like eSync support, phase offset and frequency offset reporting and phase adjustments. Testing was done by myself and by Prathosh Satish on Microchip EDS2 development board with ZL30732 DPLL chip connected over I2C bus. --- Changelog: v13: * added support for u64 devlink parameters * added support for generic devlink parameter 'clock_id' * several patches squashed into one per @jpirko's advice * renamed devlink version 'cfg.custom_ver' to 'custom_cfg' * per discussion with @jpirko, the clock_id is now generated randomly and user have an option to change it via devlink * implemented devlink reload to apply clock_id change v12: * Using 'return dev_err_probe()' * Separate zl3073x_chip_info structures instead of array * Use mul_u64_u32_div() to compute input reference frequency to avoid potential overflow * Removed superfluous check in zl3073x_dpll_output_pin_frequency_set() v11: * Fixed uninitialized 'rc' in error-path in patch 9 v10: * Usage of str_enabled_disabled() where possible. v9: After discussion with Jakub Kicinski we agreed that it would be better to implement whole functionality in a single driver without touching MFD sub-system. Besides touching multiple sub-systems by single device there are also some technical issues that are easier resolvable in a single driver. Additionally the firmware flashing functionality would bring more than 1000 lines of code with previous approach to the MFD driver - it is not something the MFD maintainers would like to see.
