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/Documentation/devicetree/bindings/mmc/mmc-controller.yaml?h=v5.7-rc6&id=fec81c5bca2499b4a263667860018c2ce47f4f51
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
