Re: [PATCH v4 03/16] PCI: dwc: imx6: Use cached PCIe capability offset

[sashiko-bot@kernel.org]

> Replace the two dw_pcie_find_capability(pci, PCI_CAP_ID_EXP) calls in
> imx_pcie_ltssm_enable() and imx_pcie_start_link() with
> dw_pcie_get_pcie_cap().
> 
> Both functions run with the controller powered and clocked: they are
> reached either from the host .start_link callback or, in Endpoint mode,
> after the PERST# deassert path has enabled the resources. The helper
> therefore performs the DBI read at the same point as the replaced call
> and caches the result for later invocations, which is useful for
> suspend/resume where the link is started again.
