PCI: cadence: Add quirk flag to set minimum delay in LTSSM Detect.Quiet state
PCIe fails to link up if SERDES lanes not used by PCIe are assigned to
another protocol. For example, link training fails if lanes 2 and 3 are
assigned to another protocol while lanes 0 and 1 are used for PCIe to
form a two lane link. This failure is due to an incorrect tie-off on an
internal status signal indicating electrical idle.
Status signals going from SERDES to PCIe Controller are tied-off when a
lane is not assigned to PCIe. Signal indicating electrical idle is
incorrectly tied-off to a state that indicates non-idle. As a result,
PCIe sees unused lanes to be out of electrical idle and this causes
LTSSM to exit Detect.Quiet state without waiting for 12ms timeout to
occur. If a receiver is not detected on the first receiver detection
attempt in Detect.Active state, LTSSM goes back to Detect.Quiet and
again moves forward to Detect.Active state without waiting for 12ms as
required by PCIe base specification. Since wait time in Detect.Quiet is
skipped, multiple receiver detect operations are performed back-to-back
without allowing time for capacitance on the transmit lines to
discharge. This causes subsequent receiver detection to always fail even
if a receiver gets connected eventually.
Add a quirk flag "quirk_detect_quiet_flag" to program the minimum
time the LTSSM should wait on entering Detect.Quiet state here.
This has to be set for J7200 as it has an incorrect tie-off on unused
lanes.

Cadence PCIe core driver (host mode) uses "cdns,no-bar-match-nbits"
property to configure the number of bits passed through from PCIe
address to internal address in Inbound Address Translation register.
This only used the NO MATCH BAR.
However standard PCI dt-binding already defines "dma-ranges" to
describe the address ranges accessible by PCIe controller. Add support
in Cadence PCIe host driver to parse dma-ranges and configure the
inbound regions for BAR0, BAR1 and NO MATCH BAR. Cadence IP specifies
maximum size for BAR0 as 256GB, maximum size for BAR1 as 2 GB.
This adds support to take the next biggest region in "dma-ranges" and
find the smallest BAR that each of the regions fit in and if there is
no BAR big enough to hold the region, split the region to see if it can
be fitted using multiple BARs.
"dma-ranges" of J721E will be
dma-ranges = <0x02000000 0x0 0x0 0x0 0x0 0x10000 0x0>;
Since there is no BAR which can hold 2^48 size, NO_MATCH_BAR will be
used here.
Legacy device tree binding compatibility is maintained by retaining
support for "cdns,no-bar-match-nbits".
