Commit 65dc2e7252 ("usb: dwc2: Update Core Reset programming flow.")
revealed that the phy isn't ready immediately after enabling it's
clocks. The dwc2_check_core_version() fails and the dwc2 usb driver
errors out.
Add a short delay to let the phy get up and running. There isn't any
documentation how much time is required, the value was chosen based on
tests.

Currently there is a null pointer check for hdmi_phy that implies it
may be null, however a dev_err messages dereferences this potential null
pointer. Avoid a null pointer dereference by only emitting the dev_err
message if hdmi_phy is non-null. It is a moot point if the error message
needs to be printed at all, but since this is a relatively new piece of
code it may be useful to keep the message in for the moment in case there
are unforseen errors that need to be reported.

Exynos5420 variant of USB2 PHY is handled by the same code as the

This driver includes the following two files directly:
- mt7621.h
- ralink_regs.h
Compilation for its related platform properly works because
its real path is included in 'arch/mips/ralink/Platform' as
cflags.
This driver depends on RALINK but also is enabled for COMPILE_TEST
where nothing about its platform is known and this directly
included files are not found at all breaking compilation.
If we want 'COMPILE_TEST' we have to change cflags also inside
'phy/ralink' subdirectory Makefile which seems that does not
like to linux-phy maintainers. Hence remove COMPILE_TEST from
Kconfig to avoid the problem.

Initially this PHY driver was implementing MDIO access on its own. It
was caused by lack of proper hardware design understanding.
It has been changed back in 2017. DT bindings were changed and driver
was updated to use MDIO layer.
It should be really safe now to drop the old deprecated code. All Linux
stored DT files don't use it for 3,5 year. There is close to 0 chance
there is any bootloader with its own DTB using old the binding.

The 7211a0 has a tca_drv_sel bit in the USB SETUP register that
should never be enabled. This feature is only used if there is a
USB Type-C PHY, and the 7211 does not have one. If the bit is
enabled, the VBUS signal will never be asserted. In the 7211a0,
the bit was incorrectly defaulted to on so the driver had to clear
the bit. In the 7211c0 the state was inverted so the driver should
no longer clear the bit. This hasn't been a problem because all
current 7211 boards don't use the VBUS signal, but there are some
future customer boards that may use it.

Add support for the USB3 + DisplayPort (DP) "combo" phy to the qmp phy
driver. We already have support for the USB3 part of the combo phy, so
most additions are for the DP phy.
Split up the qcom_qmp_phy{enable,disable}() functions into the phy init,
power on, power off, and exit functions that the common phy framework
expects so that the DP phy can add even more phy ops like
phy_calibrate() and phy_configure(). This allows us to initialize the DP
PHY and configure the AUX channel before powering on the PHY at the link
rate that was negotiated during link training.
The general design is as follows:
1) DP controller calls phy_init() to initialize the PHY and configure
the dp_com register region.
2) DP controller calls phy_configure() to tune the link rate and
voltage swing and pre-emphasis settings.
3) DP controller calls phy_power_on() to enable the PLL and power on
the phy.
4) DP controller calls phy_configure() again to tune the voltage swing
and pre-emphasis settings determind during link training.
5) DP controller calls phy_calibrate() some number of times to change
the aux settings if the aux channel times out during link training.
6) DP controller calls phy_power_off() if the link rate is to be
changed and goes back to step 2 to try again at a different link rate.
5) DP controller calls phy_power_off() and then phy_exit() to power
down the PHY when it is done.
The DP PHY contains a PLL that is different from the one used for the
USB3 PHY. Instead of a pipe clk there is a link clk and a pixel clk
output from the DP PLL after going through various dividers. Introduce
clk ops for these two clks that just tell the child clks what the
frequency of the pixel and link are. When the phy link rate is
configured we call clk_set_rate() to update the child clks in the
display clk controller on what rate is in use. The clk frequencies
always differ based on the link rate (i.e. 1.6Gb/s 2.7Gb/s, 5.4Gb/s, or
8.1Gb/s corresponding to various transmission modes like HBR1, HBR2 or
HBR3) so we simply store the link rate and use that to calculate the clk
frequencies.
The PLL enable sequence is a little different from other QMP phy PLLs so
we power on the PLL in qcom_qmp_phy_configure_dp_phy() that gets called
from phy_power_on(). This should probably be split out better so that
each phy has a way to run the final PLL/PHY enable sequence.
This code is based on a submission of this phy and PLL in the drm
subsystem.

The serdes I/O region is where the PLL for the phy is controlled.
Sometimes the PLL is shared between multiple phys, for example in the
PCIe case where there are three phys inside the same wrapper. Other
times the PLL is for a single phy, i.e. some USB3 phys. To complete the
trifecta we have the USB3+DP combo phy where the USB3 and DP phys each
have their own serdes region because they have their own PLL while they
both share a common I/O region pertaining to the USB type-c pinout and
cable orientation.
Let's move the serdes iomem pointer into 'struct qmp_phy' so that we can
correlate PLL control to the phy that uses it. This allows us to support
the USB3+DP combo phy in this driver. This isn't a problem for the
3-lane/phy PCIe phy because there is a common init function that is the
only place the serdes region is programmed.
Furthermore, move the configuration data that contains most of the
register programming sequences to the qmp phy struct. This data isn't
qmp wrapper specific. It is phy specific data used to tune various
settings for things like pre-emphasis, bias, etc.

The phy mode pertains to the phy itself, i.e. 'struct qmp_phy', not the
wrapper, i.e. 'struct qcom_qmp'. Move the phy mode into the phy
structure to more accurately reflect what is going on. This also cleans
up 'struct qcom_qmp' so that it can eventually be the place where qmp
wrapper wide data is located, paving the way for the USB3+DP combo phy.

The mvneta hardware appears to lock up in various random ways when
repeatedly switching speeds between 1G and 2.5G, which involves
reprogramming the COMPHY. It is not entirely clear why this happens,
but best guess is that reprogramming the COMPHY glitches mvneta clocks
causing the hardware to fail. It seems that rebooting resolves the
failure, but not down/up cycling the interface alone.
Various other approaches have been tried, such as trying to cleanly
power down the COMPHY and then take it back through the power up
initialisation, but this does not seem to help.
It was finally noticed that u-boot's last step when configuring a
COMPHY for "SGMII" mode was to poke at a register described as
"GBE_CONFIGURATION_REG", which is undocumented in any external
documentation. All that we have is the fact that u-boot sets a bit
corresponding to the "SGMII" lane at the end of COMPHY initialisation.
Experimentation shows that if we clear this bit prior to changing the
speed, and then set it afterwards, mvneta does not suffer this problem
on the SolidRun Clearfog when switching speeds between 1G and 2.5G.
This problem was found while script-testing phylink.
This fix also requires the corresponding change to DT to be effective.

speeds".

This means free_irq() calls the interrupt handler while PM runtime
is not getting if DEBUG_SHIRQ is enabled and rcar_gen3_phy_usb2_probe()
failed. To fix the issue, move the irq registration place to
rcar_gen3_phy_usb2_init() which is ready to handle the interrupts.
Note that after the commit 549b6b55b0 ("phy: renesas: rcar-gen3-usb2:

driver creates multiple phy instances, needs to check whether one of
phy instances is initialized. However, if we backport this patch to v5.1
or less, we don't need to check it because such kernel have single

Currently pointer phy0 is being dereferenced via the assignment of

During different reboot cycles, USB PHY PLL may not always lock

It's possible that struct qmp_phy_cfg->regs references an array that is
smaller than the possible register lookups that is going to be
performed, with the resulting out-of-bounds read resulting in undefined
behavior.
One such example is when during qcom_qmp_phy_com_init() performs a
qphy_setbits() on entry QPHY_PCS_POWER_DOWN_CONTROL (i.e. 17) with
msm8996_ufsphy_regs_layout only being 12 entries long.
Solve this by inflating all "regs_layout" arrays to ensure that any
remaining entries are zero-initialized, as expected by the code.

This manifested in issues with the DWC2 driver since commit fe369e1826

where the endianness check would read the DWC ID as 0 due to the phy still

In commit 8fe75cd4cd ("phy: qcom-qusb2: Add generic QUSB2 V2

as a generic compat string. However the change also removed
the "qcom,sdm845-qusb2-phy" compat string, which is documented
in the binding and already in use.
This patch re-adds the "qcom,sdm845-qusb2-phy" compat string
which allows the driver to continue to work with existing dts
entries such as found on the db845c.

The phy-gmii-sel can be only auto selected in Kconfig and now the pretty
complex Kconfig dependencies are defined for phy-gmii-sel driver, which
also need to be updated every time phy-gmii-sel is re-used for any new
networking driver.
Simplify Kconfig definition for phy-gmii-sel PHY driver - drop all
dependencies and from networking drivers and rely on using 'imply
PHY_TI_GMII_SEL' in Kconfig definitions for networking drivers instead.

Adds Qualcomm 28nm Hi-Speed USB PHY driver support. This PHY is usually
paired with Synopsys DWC3 USB controllers on Qualcomm SoCs.
The PHY can come in two flavours femtoPHY or picoPHY. This commit adds
support for the femtoPHY with the possibility of extending to the picoPHY
with additional future commits. Both PHYs are on a 28 nanometer process
node.

Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.
