Also, this series depends on the following change of yours
http://patchwork.ozlabs.org/patch/1109884/
Whats the plan to get this merged?
I've posted the endpoint improvements as a separate series
http://lore.kernel.org/r/20191231100331.6316-1-kishon@xxxxxx
I'd prefer this series gets tested by others. I'm also planning to test
this series. Sorry for the delay. I'll test review and test this series
early next week.
Hi Kishon,
Just wanted to know if you got time to test review my patches.
Thanks,
Vidya Sagar
Thanks

EPC/DesignWare core endpoint subsystems assume that the core
registers are
available always for SW to initialize. But, that may not be the case
always.
For example, Tegra194 hardware has the core running on a clock that
is derived
from reference clock that is coming into the endpoint system from host.
Hence core is made available asynchronously based on when host system
is going
for enumeration of devices. To accommodate this kind of hardwares,
support is
required to defer the core initialization until the respective
platform driver
informs the EPC/DWC endpoint sub-systems that the core is indeed
available for
initiaization. This patch series is attempting to add precisely that.
This series is based on Kishon's patch that adds notification mechanism
support from EPC to EPF @ http://patchwork.ozlabs.org/patch/1109884/

PCI: endpoint: Add core init notifying feature
PCI: dwc: Refactor core initialization code for EP mode
PCI: endpoint: Add notification for core init completion
PCI: dwc: Add API to notify core initialization completion
PCI: pci-epf-test: Add support to defer core initialization
