Subject: [PATCH v3 0/2] net: stmmac: correct MAC propagation delay

---
Changes in v3:
- work in Richard's review feedback. Thank you for reviewing my patch:
  - as some of the hardware may have no or invalid correction value
    registers: introduce feature switch which can be enabled in the glue
    code drivers depending on the actual hardware support
  - only enable the feature on the i.MX8MP for the time being, as the patch
    improves timing accuracy and is tested for this hardware
- Link to v2: https://lore.kernel.org/r/20230719-stmmac_correct_mac_delay-v2-1-3366f38ee9a6@pengutronix.de

Changes in v2:
- fix builds for 32bit, this was found by the kernel build bot
	Reported-by: kernel test robot <lkp@...el.com>
	Closes: https://lore.kernel.org/oe-kbuild-all/202307200225.B8rmKQPN-lkp@intel.com/
- while at it also fix an overflow by shifting a u32 constant from macro by 10bits
  by casting the constant to u64
