f7f9abc5ea phy: freescale: imx8m-pcie: Handle IMX8_PCIE_REFCLK_PAD_UNUSED
The 'fsl,refclk-pad-mode' DT property used to select clock source for
PCIe PHY can have either of three values, IMX8_PCIE_REFCLK_PAD_INPUT,
IMX8_PCIE_REFCLK_PAD_OUTPUT, IMX8_PCIE_REFCLK_PAD_UNUSED. The first
two options are handled correctly by the driver, the last one is not,
this patch implements support for the last option.

The IMX8_PCIE_REFCLK_PAD_INPUT means PCIE_RESREF is PHY clock input,
the IMX8_PCIE_REFCLK_PAD_OUTPUT means PHY clock are sourced from SoC
internal PLL and output to PCIE_RESREF external IO pin. The last
IMX8_PCIE_REFCLK_PAD_UNUSED is a combination of previous two, PHY
clock are sourced from SoC internal PLL and not output anywhere.

6a98df08cc phy: rockchip-inno-usb2: Fix muxed interrupt support
This commit fixes two issues with the muxed interrupt handler. First,
the OTG port has the "bvalid" interrupt enabled, not "linestate". Since
only the linestate interrupt was handled, and not the bvalid interrupt,
plugging in a cable to the OTG port caused an interrupt storm.

Second, the return values from the individual port IRQ handlers need to
be OR-ed together. Otherwise, the lack of an interrupt from the last
port would cause the handler to erroneously return IRQ_NONE.

The Allwinner A31 D-PHY supports both Rx and Tx modes. While the latter
is already supported and used for MIPI DSI this adds support for the
former, to be used with MIPI CSI-2.

This implementation is inspired by Allwinner's V3s Linux SDK
implementation, which was used as a documentation base.

It uses the direction dt property to distinguish between tx and rx
directions.

The Allwinner A31 MIPI D-PHY block supports both tx and rx directions,
although each instance of the block is meant to be used in one
direction only. There will typically be one instance for MIPI DSI and
one for MIPI CSI-2 (it seems unlikely to ever see a shared instance).

Describe the direction with a new allwinner,direction property.
For backwards compatibility, the property is optional and tx mode
should be assumed by default.

3fbae28488 phy: freescale: phy-fsl-imx8-mipi-dphy: Add i.MX8qxp LVDS PHY mode support
i.MX8qxp SoC embeds a Mixel MIPI DPHY + LVDS PHY combo which supports
either a MIPI DSI display or a LVDS display.  The PHY mode is controlled
by SCU firmware and the driver would call a SCU firmware function to
configure the PHY mode.  The single LVDS PHY has 4 data lanes to support
a LVDS display.  Also, with a master LVDS PHY and a slave LVDS PHY, they
may work together to support a LVDS display with 8 data lanes(usually, dual
LVDS link display).  Note that this patch supports the LVDS PHY mode only
for the i.MX8qxp Mixel combo PHY, i.e., the MIPI DPHY mode is yet to be
supported, so for now error would be returned from ->set_mode() if MIPI
DPHY mode is passed over to it for the combo PHY.

f9b0593dd4 dt-bindings: phy: Convert mixel,mipi-dsi-phy to json-schema
This patch converts the mixel,mipi-dsi-phy binding to
DT schema format using json-schema.

Comparing to the plain text version, the new binding adds
the 'assigned-clocks', 'assigned-clock-parents' and
'assigned-clock-rates' properites, otherwise 'make dtbs_check'
would complain that there are mis-matches.  Also, the new
binding requires the 'power-domains' property since all potential
SoCs that embed this PHY would provide a power domain for it.
The example of the new binding takes reference to the latest
dphy node in imx8mq.dtsi.

e72659b69f phy: cadence: Sierra: Add TI J721E specific PCIe multilink lane configuration
This patch adds workaround for TI J721E errata i2183
(https://www.ti.com/lit/er/sprz455a/sprz455a.pdf).
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.

The workaround only works for 1-lane PCIe configuration. This workaround
involves enabling receiver detect override by setting TX_RCVDET_OVRD_PREG_j
register of the lane running PCIe to 0x2. This causes SERDES to indicate
successful receiver detect when LTSSM is in Detect.Active state, whether a
receiver is actually present or not. If the receiver is present, LTSSM
proceeds to link up as expected. However if receiver is not present, LTSSM
will time out in Polling.Configuration substate since the expected training
sequence packets will not be received.

e4d4371253 phy: phy-can-transceiver: Add support for setting mux
On some boards, for routing CAN signals from controller to transceiver,
muxes might need to be set. Therefore, add support for setting the mux by
reading the mux-states property from the device tree node.

- Rename the staging files to give them some meaning.
   Just stage1,stag2,etc, does not show what they are for
 
 - Check for NULL from allocation in bootconfig
 
 - Hold event mutex for dyn_event call in user events
 
 - Mark user events to broken (to work on the API)
 
 - Remove eBPF updates from user events
 
 - Remove user events from uapi header to keep it from being installed.

8b5656bc4e A set of x86 fixes and updates:
- Make the prctl() for enabling dynamic XSTATE components correct so it
     adds the newly requested feature to the permission bitmap instead of
     overwriting it. Add a selftest which validates that.
 
   - Unroll string MMIO for encrypted SEV guests as the hypervisor cannot
     emulate it.
 
   - Handle supervisor states correctly in the FPU/XSTATE code so it takes
     the feature set of the fpstate buffer into account. The feature sets
     can differ between host and guest buffers. Guest buffers do not contain
     supervisor states. So far this was not an issue, but with enabling
     PASID it needs to be handled in the buffer offset calculation and in
     the permission bitmaps.
 
   - Avoid a gazillion of repeated CPUID invocations in by caching the values
     early in the FPU/XSTATE code.
 
   - Enable CONFIG_WERROR for X86.
 
   - Make the X86 defconfigs more useful by adapting them to Y2022 reality.

multiple reports that this breaks boot on various systems. The common
theme is that orphan clks are having rates set on them when that isn't
expected. Let's revert it out for now so that -rc1 boots.

bf5c0c2231 modpost: restore the warning message for missing symbol versions
This log message was accidentally chopped off.

I was wondering why this happened, but checking the ML log, Mark
precisely followed my suggestion [1].

I just used "..." because I was too lazy to type the sentence fully.
Sorry for the confusion.
