This series implements PHY tuning support for the Cadence QSPI controller
to enable reliable high-speed operations. Without PHY tuning, controllers
use conservative timing that limits performance. PHY tuning calibrates
RX/TX delay lines to find optimal data capture timing windows, enabling
operation up to the controller's maximum frequency.


A few of the issues reported by sashiko-bot are valid. I'll address
those fixes and respin the series shortly.

Thanks,
Santhosh.
