[PATCH 0/9] PCI: qcom: Add PCIe support for Shikra SoC

[PATCH 0/9] PCI: qcom: Add PCIe support for Shikra SoC

[Sushrut Shree Trivedi]

Add PCIe support for Shikra target, by adding dt-bindings for phy,
controller and corresponding phy & controller drivers/device-tree
changes.

Shikra RC is connected to TC9563 PCIe switch on all three
EVK variants: CQS, CQM and IQS. The individual downstream ports
of TC9563 connect like below:

DSP1: M.2 B-Key for 5G Modem
DSP2: M.2 M-Key for NVMe
DSP3: Embedded ethernet device

Power and reset to M.2 B and M.2 M slot are controlled via
TC9563 GPIO's. Hence, add DT nodes to enable TC9563 switch
and include corresponding changes to configure power/reset
to TC9563 endpoints as part of power on sequence.

[PATCH 6/9] PCI/pwrctrl: tc9563: Add API to control endpoint power and reset

[Sushrut Shree Trivedi]

Some platform utilise TC9563 GPIOs to enable power and
control reset of endpoints.

This patch adds support to parse endpoint reset and power enable
gpios from each TC9563 port node in the devicetree. To configure
these GPIO's during the POWER ON sequence, two new API's are
introduced: tc9563_ep_pwr_en() and tc9563_ep_assert_deassert_reset().

[PATCH 8/9] arm64: dts: qcom: shikra-evk: Add TC9563 PCIe switch node for PCIe

[Sushrut Shree Trivedi]

Add a node for the TC9563 PCIe switch connected to PCIe. The switch
has three downstream ports.Two embedded Ethernet devices are present
on one of the downstream ports. All the ports present in the
node represent the downstream ports and embedded endpoints.

Power to the TC9563 is supplied through two LDO regulators, which
are on by default and are added as fixed regulators. TC9563 can be
configured through I2C.

[PATCH 9/9] arm64: dts: qcom: shikra-(cqm/cqs/iqs)-evk: Enable PCIe PHY node

[Sushrut Shree Trivedi]

Enable the PCIe PHY for the single PCIe intance on the Shikra
CQS, CQM and the IQS platforms.

IQS platform uses a different powergrid than CQS/CQM which explain
the different PHY supplies for IQS variant.

Existing schema names are almost all "qcom,pcie-<SOC>", not
"qcom,<SOC>-pcie".

Subject lines typically include the SoC, e.g., see
"git log --oneline --no-merges Documentation/devicetree/bindings/pci/qcom*"

Include context in subject line.  Regrettably, previous commits to
toshiba,tc9563.yaml don't include that either, but I think something
like this would be good:

Possibly subject doesn't need two uses of "PCIe".

Same comments as other recent Qualcomm bindings. Don't invent stuff,
take what was reviewed from the list so we won't have to repeat.

And you change indentation because?


Just like the other patch, this wasn't tested, right?

Please add a single-line comment right above explaining that the
host supports higher speeds, but the attached PHY is only Gen2,
so we need this manual limitation

This property belongs to the port node

Please also mention in the commit message the reason for the
PERST# pin remaining undescribed

I think it makes sense to push the status=okay to the evk file
(because we already describe the PCIe switch there) and only keep
the supplies here (because they differ)
