Hi,
this patchset adding support for Tap delay programming for ZynqMP and Versal. Based on mainline discussion also DT properties have been introduced which are documented here. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/Do... The patchset is using these DT properties which are optional. Default values are also listed.
The patchset is based on: https://lists.denx.de/pipermail/u-boot/2020-May/410326.html
Also new code is adding checking for SOCs which are not needed at that time when patch is applied (For example "mmc: zynq_sdhci: Read clock phase delays from dt" and IS_ENABLED(CONFIG_ARCH_ZYNQMP)... But I kept it there for more cleaner patches built on the top.
Thanks, Michal
