As the ICC_GET stub function returns NULL and it's valid, PCIe controller
driver must continue without returning an error. This is the case when
CONFIG_INTERCONNECT is not set.

qcom_clk_dump function internally has sleeping calls like
mutext locks. We should not use this function in interrupt/

PCIe keeps Qactive signal asserted when link is active (L0).
It de-asserts it when link is in L1SS or D3Hot. In case of
L2, Qactive is not de-asserted, this prevents SNOC power
collapse. Fix this issue by asserting Qactive upon link
enable(L0) and de-assert it upon link disable(L2) using
PCIE20_PARF_CFG_BITS_3 register.

This change is to proceed PCIe RC probe even icc handles are not present
in SDX75 RUMI validations.
Currently icc changes are not mainlined and hence avoiding the issues
related to icc in PCIe code.

Add support for reading tcsr configuration from device tree and
configuring tcsr register dynamically.
This change for supporting sa8195p PCIe1. The default PCIe linkage
status of PCIe1 and 2 on sa8195p is:
PCIe1: not enabled
PCIe2: x4 lane
When config the register TCSR_PCIEPHY_LINK_CONFIG to 0(default 1),
the linkage status becomes:
PCIe1: x2 lane
PCIe2: x2 lane
This change add the ability to read tcsr value from device tree.

Add support for QRTR to forward messages between network clusters. The
network subnet id's are attached to the QRTR subnodes in the MHI and
RPMSG/GLINK nodes.
The current forwarding decisions are done based on the net ids and are
wrapped in a single function for easier maintenance of forwarding
decisions later on. The function will return true once it determines
a subnet has no connection to another subnet.
The NEW_SERVER, DEL_SERVER, and DEL_CLIENT control messages should be
forwarded while the DATA and RESUME_TX commands should be passed along
to their destination node.
The nameservice is expected to send NEW_SERVER commands for it's entire
database instead of just the local service database with these changes.
This is to make sure new nodes get service notifications that came
earlier and were meant to be forwarded to the new node.
This change squashes the following commits from msm-4.14:
commit e5f6a6769ceb ("net: qrtr: Add forwarding support based on net id")
commit 4516ab18718d ("net: qrtr: avoid deadlock in case of recursive
lock for node list")
commit dc2d47cd12d3 ("net: qrtr: Only update pkts with broadcast node
ID")
commit 4277aebeff91 ("net: qrtr: Free skb if qrtr_node_lookup fails
during qrtr_fwd_pkt")
In addition fix minor format issues and update copyright.

There is a requirement where slimbus slave don't expect ports
to be disconnected during stream unprepare for sample rates
other than 44.1/88.2k, which is causing mute issues.
Added new slim_stream_unprepare_disconnect_port API to support
disconnect port request from clients without freeing port memory
allocated during stream prepare.
