[ Upstream commit b36fb50701619efca5f5450b355d42575cf532ed ]

If an error occurs after a successful phy_init() call, then phy_exit()
should be called.

Add the missing call, as already done in the remove function.

<title>PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar()</title>

commit 3708acbd5f169ebafe1faa519cb28adc56295546 upstream.

In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update
inbound map address") set_bar() was modified to support dynamically
changing the backing physical address of a BAR that was already configured.

This means that set_bar() can be called twice, without ever calling
clear_bar() (as calling clear_bar() would clear the BAR's PCI address
assigned by the host).

This can only be done if the new BAR size/flags does not differ from the
existing BAR configuration. Add these missing checks.

If we allow set_bar() to set e.g. a new BAR size that differs from the
existing BAR size, the new address translation range will be smaller than
the BAR size already determined by the host, which would mean that a read
past the new BAR size would pass the iATU untranslated, which could allow
the host to read memory not belonging to the new struct pci_epf_bar.

While at it, add comments which clarifies the support for dynamically
changing the physical address of a BAR. (Which was also missing.)

<title>PCI: dwc: ep: Write BAR_MASK before iATU registers in pci_epc_set_bar()</title>

commit 33a6938e0c3373f2d11f92d098f337668cd64fdd upstream.

The "DesignWare Cores PCI Express Controller Register Descriptions,
Version 4.60a", section "1.21.70 IATU_LWR_TARGET_ADDR_OFF_INBOUND_i",
fields LWR_TARGET_RW and LWR_TARGET_HW both state that:
"Field size depends on log2(BAR_MASK+1) in BAR match mode."

I.e. only the upper bits are writable, and the number of writable bits is
dependent on the configured BAR_MASK.

If we do not write the BAR_MASK before writing the iATU registers, we are
relying the reset value of the BAR_MASK being larger than the requested
BAR size (which is supplied in the struct pci_epf_bar which is passed to
pci_epc_set_bar()). The reset value of the BAR_MASK is SoC dependent.

Thus, if the struct pci_epf_bar requests a BAR size that is larger than the
reset value of the BAR_MASK, the iATU will try to write to read-only bits,
which will cause the iATU to end up redirecting to a physical address that
is different from the address that was intended.

Thus, we should always write the iATU registers after writing the BAR_MASK.

[ Upstream commit 86a016e278b78cc2281edd4ffaddbc011c87a593 ]

On the i.MX8QM, PCIe link can't be re-established again in
dw_pcie_resume_noirq(), if the LTSSM_EN bit is not cleared
properly in dw_pcie_suspend_noirq().

So, add dw_pcie_stop_link() to dw_pcie_suspend_noirq() to fix
this issue and to align the suspend/resume functions since there
is dw_pcie_start_link() in dw_pcie_resume_noirq() already.

4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up event in
'global_irq' interrupt") added the Link Up-based enumeration support, but
did not update the ICC/OPP vote once link is up. Before that, the update
happened during probe and the endpoints may or may not be enumerated at
that time, so the ICC/OPP vote was not guaranteed to be accurate.

With Link Up-based enumeration support, the driver can request the accurate
vote based on the PCIe link.

Call qcom_pcie_icc_opp_update() in qcom_pcie_global_irq_thread() after
enumerating the endpoints.

[ Upstream commit ef61c7d8d032adb467f99d03ccfaa293b417ac75 ]

Since the apps_reset is asserted in imx_pcie_assert_core_reset(), it should
be deasserted in imx_pcie_deassert_core_reset().

<title>PCI: imx6: Skip controller_id generation logic for i.MX7D</title>

<content type='text'>
[ Upstream commit f068ffdd034c93f0c768acdc87d4d2d7023c1379 ]

The i.MX7D only has one PCIe controller, so controller_id should always be
0. The previous code is incorrect although yielding the correct result.

Fix by removing "IMX7D" from the switch case branch.

[ Upstream commit de22e20589b79f35f92543119c33051f8179dba0 ]

Pass PHY_MODE_PCIE_EP if the PCI controller operates in Endpoint (EP) mode,
and fix the Root Complex (RC) mode being hardcoded using a drvdata mode
check.
