Changes since v2: https://lore.kernel.org/all/20220801184656.702930-1-matej.vasilevski@seznam.cz/t/#u - proper timestamping clock handling - clocks manually enabled using clk_prepare_enable, then managed by runtime PM (if runtime PM is enabled) - driver should work even without CONFIG_PM - access to the timecounter is now protected by a spinlock - harmonized with Vincent's patch - TX timestamping capability is now correctly reported - work_delay_jiffies stored as unsigned long instead of u32 - max work delay limited to 3600 seconds (instead of 86k seconds) - adressed the rest of the comments from the patch V2 review Changes since v1: https://lore.kernel.org/all/20220512232706.24575-1-matej.vasilevski@seznam.cz/ - Removed kconfig option to enable/disable timestamps. - Removed dt parameters ts-frequency and ts-used-bits. Now the user only needs to add the timestamping clock phandle to clocks, and even that is optional. - Added SIOCSHWTSTAMP ioctl to enable/disable timestamps. - Adressed comments from the RFC review.
