[PATCH v12 0/8] PCI: dwc: ep: Fix DBI access failure for drivers requiring refclk from host

[Krzysztof Wilczyński]

Hello,

> This series is the continuation of previous work by Vidya Sagar [1] to fix the
> issues related to accessing DBI register space before completing the core
> initialization in some EP platforms like Tegra194/234 and Qcom EP.
> 
> Since Vidya is busy, I took over the series based on his consent (off-list
> discussion).
> 
> NOTE
> ====
> 
> Based on the comments received in v7 [2], I've heavily modified the series
> to fix several other issues reported by Bjorn and Niklas. One noticeable
> change is getting rid of the 'core_init_notifer' flag added to differentiate
> between glue drivers requiring refclk from host and drivers getting refclk
> locally.
> 
> By getting rid of this flag, now both the DWC EP driver and the EPF drivers
> can use a single flow and need not distinguish between the glue drivers.
> 
> We can also get rid of the 'link_up_notifier' flag in the future by following
> the same convention.
> 
> Testing

> 
> I've tested the series on Qcom SM8450 based dev board that depends on refclk
> from host with EPF_MHI driver. It'd be good to test this series on platforms
> that generate refclk locally and also with EPF_TEST driver.

Applied to controller/dwc, thank you!
