MT2712 and MT7622 using a new IP block of Gen2 controller which has two
root ports and shares the same probing flow with MT2701/MT7623.
Both MT2712 and MT7622 have the same per-port control registers, but
there are slight differences between them:
- MT7622 has more clocks than MT2712.
- MT7622 has shared control registers which are used to enable LTSSM and
ASPM while MT2712 does not.
Add host controller support for MT2712/MT7622.

This is a transitional patch. We currently use platfarm_get_resource() for
retrieving the IOMEM resources, but there might be some chips don't have
subsys/shared registers part, which depends on platform design, and these
will be introduced in further patches.
Switch this function to use the platform_get_resource_byname() so that the
binding can be agnostic of the resource order.

Configuration Request Retry Status ("CRS") completions are a required part
of PCIe. A PCIe device may respond to config a request with a CRS
completion to indicate that it needs more time to initialize. A Root Port
that receives a CRS completion may automatically retry the request, or it
may treat the request as a failed transaction. For a failed read, it will
likely synthesize all 1's data, i.e., 0xffffffff, to complete the read to
the CPU.
CRS Software Visibility ("CRS SV") is an optional feature. Per PCIe r3.1,
sec 2.3.2, if supported and enabled, a Root Port that receives a CRS
completion for a config read of the Vendor ID will synthesize 0x0001 data
(an invalid Vendor ID) instead of retrying or failing the transaction. The
0x0001 data makes the CRS completion visible to software, so it can perform
other tasks while waiting for the device.
The iProc "Stingray" PCIe controller does not support CRS completions
correctly. From the Stingray PCIe Controller spec:
4.7.3.3. Retry Status On Configuration Cycle
Endpoints are allowed to generate retry status on configuration cycles.
In this case, the RC needs to re-issue the request. The IP does not
handle this because the number of configuration cycles needed will
probably be less than the total number of non-posted operations needed.
When a retry status is received on the User RX interface for a
configuration request that was sent on the User TX interface, it will be
indicated with a completion with the CMPL_STATUS field set to 2=CRS, and
the user will have to find the address and data values and send a new
transaction on the User TX interface. When the internal configuration
space returns a retry status during a configuration cycle (user_cscfg =
1) on the Command/Status interface, the pcie_cscrs will assert with the
pcie_csack signal to indicate the CRS status.
When the CRS Software Visibility Enable register in the Root Control
register is enabled, the IP will return the data value to 0x0001 for the
Vendor ID value and 0xffff (all 1’s) for the rest of the data in the
request for reads of offset 0 that return with CRS status. This is true
for both the User RX Interface and for the Command/Status interface.
When CRS Software Visibility is enabled, the CMPL_STATUS field of the
completion on the User RX Interface will not be 2=CRS and the pcie_cscrs
signal will not assert on the Command/Status interface.
The Stingray hardware never reissues configuration requests when it
receives CRS completions. Contrary to what sec 4.7.3.3 above says, when it
receives a CRS completion, it synthesizes 0xffff0001 data regardless of the
address of the read or the value of the CRS SV enable bit.
This is broken in two ways:
1) When CRS SV is disabled, the Root Port should never synthesize the
0x0001 value. If it receives a CRS completion, it should fail the
transaction and synthesize all 1's data.
2) When CRS SV is enabled, the Root Port should only synthesize 0x0001
data if it receives a CRS completion for a read of the Vendor ID. If it
receives a CRS completion for any other read, it should fail the
transaction and synthesize all 1's data.
This breaks pci_flr_wait(), which reads the Command register and expects to
see all 1's data if the read fails because of CRS completions. On
Stingray, it sees the incorrect 0xffff0001 data instead.
It also breaks config registers that contain the 0xffff0001 value. If we
read such a register, software can't distinguish a CRS completion from the
actual value read from the device.
On Stingray, if we read 0xffff0001 data, assume this indicates a CRS
completion and retry the read for 500ms. If we time out, return all 1's
(0xffffffff) data. Note that this corrupts registers that happen to
contain 0xffff0001.
Stingray advertises CRS SV support in its Root Capabilities register, and
the CRS SV enable bit is writable (even though the hardware ignores it).
Mask out PCI_EXP_RTCAP_CRSVIS so software doesn't try to use CRS SV.
