commit 1dea06cd643da38931382ebdc151efced201ffad upstream.
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.
See "ARM: dts: armada-38x: fix NETA lockup when repeatedly switching
speeds".

commit 08b0ad375ca66181faee725b1b358bcae8d592ee upstream.
If CONFIG_DEBUG_SHIRQ was enabled, r8a77951-salvator-xs could boot
correctly. If we appended "earlycon keep_bootcon" to the kernel
command like, we could get kernel log like below.
SError Interrupt on CPU0, code 0xbf000002 -- SError
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.8.0-rc3-salvator-x-00505-g6c843129e6faaf01 #785
Hardware name: Renesas Salvator-X 2nd version board based on r8a77951 (DT)
pstate: 60400085 (nZCv daIf +PAN -UAO BTYPE=--)
pc : rcar_gen3_phy_usb2_irq+0x14/0x54
lr : free_irq+0xf4/0x27c
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 549b6b55b005 ("phy: renesas: rcar-gen3-usb2:
enable/disable independent irqs") which is merged into v5.2, since this
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
phy instance.

commit 38b1927e5bf9bcad4a2e33189ef1c5569f9599ba upstream.
Currently pointer phy0 is being dereferenced via the assignment of
phy on the call to phy_get_drvdata before phy0 is null checked, this
can lead to a null pointer dereference. Fix this by performing the
null check on phy0 before the call to phy_get_drvdata. Also replace
the phy0 == NULL check with the more usual !phy0 idiom.

commit eefed634eb61e4094b9fb8183cb8d43b26838517 upstream.
- under PHY_INTERFACE_MODE_MII the 'mode' func parameter is assigned
instead of 'gmii_sel_mode' and it's working only because the default value
'gmii_sel_mode' is set to 0.
- console outputs use 'rgmii_id' and 'mode' values to print PHY mode
instead of using 'submode' value which is representing PHY interface mode
now.
This patch fixes above two cases.

commit 46b7edf1c7b7c91004c4db2c355cbd033f2385f9 upstream.
I've noticed that when writing data to the modem the writes can time out
at some point eventually. Looks like kicking the modem idle GPIO every
600 ms instead of once a second fixes the issue. Note that this rate is
different from our runtime PM autosuspend rate MDM6600_MODEM_IDLE_DELAY_MS
that we still want to keep at 1 second, so let's add a separate define for
PHY_MDM6600_IDLE_KICK_MS.

commit be4e3c737eebd75815633f4b8fd766defaf0f1fc upstream.
We have an interrupt handler for the wake-up GPIO pin, but we're missing
the code to wake-up the system. This can cause timeouts receiving data
for the UART that shares the wake-up GPIO pin with the USB PHY.
All we need to do is just wake the system and kick the autosuspend
timeout to fix the issue.

commit 63078b6ba09e842f09df052c5728857389fddcd2 upstream.
The micro-USB connector on Motorola Mapphone devices can be muxed between
the SoC and the mdm6600 modem. But even when used for the SoC, configuring
the PHY with ID pin grounded will wake up the modem from idle state. Looks
like the issue is probably caused by line glitches.
We can prevent the glitches by using a previously unknown mode of the
GPIO mux to prevent the USB lines from being connected to the moden while
configuring the USB PHY, and enable the USB lines after configuring the
PHY.
Note that this only prevents waking up mdm6600 as regular USB A-host mode,
and does not help when connected to a lapdock. The lapdock specific issue
still needs to be debugged separately.

commit 4f510aa10468954b1da4e94689c38ac6ea8d3627 upstream.
Commit 287422a95fe2 ("drm/rockchip: Round up _before_ giving to the clock framework")
changed what rate clk_round_rate() is called with, an additional 999 Hz
added to the requsted mode clock. This has caused a regression on RK3328
and presumably also on RK3228 because the inno-hdmi-phy clock requires an
exact match of the requested rate in the pre pll config table.
When an exact match is not found the parent clock rate (24MHz) is returned
to the clk_round_rate() caller. This cause wrong pixel clock to be used and
result in no-signal when configuring a mode on RK3328.
Fix this by rounding the rate down to closest 1000 Hz in round_rate func,
this allows an exact match to be found in pre pll config table.

commit 64f86b9978449ff05bfa6c64b4c5439e21e9c80b upstream.
Commit f0b5c2c96370 ("phy: qcom-usb-hs: Replace the extcon API")
switched from extcon_register_notifier() to the resource-managed
API, i.e. devm_extcon_register_notifier().
This is problematic in this case, because the extcon notifier
is dynamically registered/unregistered whenever the PHY is powered
on/off. The resource-managed API does not unregister the notifier
until the driver is removed, so as soon as the PHY is power cycled,
attempting to register the notifier again results in:
double register detected
WARNING: CPU: 1 PID: 182 at kernel/notifier.c:26 notifier_chain_register+0x74/0xa0

qcom_usb_hs_phy_power_on+0x1fc/0x208
...
... and USB stops working after plugging the cable out and in
another time.
The easiest way to fix this is to make a partial revert of
commit f0b5c2c96370 ("phy: qcom-usb-hs: Replace the extcon API")
and avoid using the resource-managed API in this case.

[ Upstream commit 14ced7e3a1ae9bed7051df3718c8c7b583854a5c ]
Despite extensive testing of commit 885bd765963b ("phy: qcom-qmp: Correct
READY_STATUS poll break condition") I failed to conclude that the
PHYSTATUS bit of the PCS_STATUS register used in PCIe and USB3 falls as
the PHY gets ready. Similar to the prior bug with UFS the code will
generally get past the check before the transition and thereby
"succeed".
Correct the name of the register used PCIe and USB3 PHYs, replace
mask_pcs_ready with a constant expression depending on the type of the
PHY and check for the appropriate ready state.

commit e6839c31a608e79f2057fab987dd814f5d3477e6 upstream.
The hardware manual should be revised, but the initial value of
VBCTRL.OCCLREN is set to 1 actually. If the bit is set, the hardware
clears VBCTRL.VBOUT and ADPCTRL.DRVVBUS registers automatically
when the hardware detects over-current signal from a USB power switch.
However, since the hardware doesn't have any registers which
indicates over-current, the driver cannot handle it at all. So, if
"is_otg_channel" hardware detects over-current, since ADPCTRL.DRVVBUS
register is cleared automatically, the channel cannot be used after
that.
To resolve this behavior, this patch sets the VBCTRL.OCCLREN to 0
to keep ADPCTRL.DRVVBUS even if the "is_otg_channel" hardware
detects over-current. (We assume a USB power switch itself protects
over-current and turns the VBUS off.)
This patch is inspired by a BSP patch from Kazuya Mizuguchi.

[ Upstream commit 5fc2aa3ec9efad97dd7c316f3c8e4c6268bbed9b ]
Locking is not needed for the phy_g12a_usb3_pcie_cr_bus_read/write() and
currently it causes the following BUG because of the usage of the
regmap_read_poll_timeout() running in spinlock_irq, configured by regmap fast_io.
Simply disable locking in the cr_regmap config since it's only used from the
PHY init callback function.
BUG: sleeping function called from invalid context at drivers/phy/amlogic/phy-meson-g12a-usb3-pcie.c:85

[ Upstream commit 5c9dc6379f539c68a0fdd39e39a9d359545649e9 ]
The powered flag should be set for any other phys anyway. Also
the flag should be locked by the channel. Otherwise, after we have
revised the device tree for the usb phy, the following warning
happened during a second system suspend. And if the driver doesn't
lock the flag, an imbalance is possible when enabling the regulator
during system resume. So, this patch fixes the issues.

commit 885bd765963b42c380db442db7f1c0f2a26076fa upstream.
After issuing a PHY_START request to the QMP, the hardware documentation
states that the software should wait for the PCS_READY_STATUS to become
1.
With the introduction of commit c9b589791fc1 ("phy: qcom: Utilize UFS
reset controller") an additional 1ms delay was introduced between the
start request and the check of the status bit. This greatly increases
the chances for the hardware to actually becoming ready before the
status bit is read.
The result can be seen in that UFS PHY enabling is now reported as a
failure in 10% of the boots on SDM845, which is a clear regression from
the previous rare/occasional failure.
This patch fixes the "break condition" of the poll to check for the
correct state of the status bit.
Unfortunately PCIe on 8996 and 8998 does not specify the mask_pcs_ready
register, which means that the code checks a bit that's always 0. So the
patch also fixes these, in order to not regress these targets.
Fixes: 73d7ec899bd8 ("phy: qcom-qmp: Add msm8998 PCIe QMP PHY support")
Fixes: e78f3d15e115 ("phy: qcom-qmp: new qmp phy driver for qcom-chipsets")

Prior to the adoption of SPDX, it was difficult for tools to determine
the correct license due to incomplete or badly formatted license text.
The SPDX solves this issue, assuming people can correctly spell
"SPDX-License-Identifier" although this assumption is broken in some
places.
Since scripts/spdxcheck.py parses only lines that exactly matches to
the correct tag, it cannot (should not) detect this kind of error.
If the correct tag is missing, scripts/checkpatch.pl warns like this:
WARNING: Missing or malformed SPDX-License-Identifier tag in line *
So, people should notice it before the patch submission, but in reality
broken tags sometimes slip in. The checkpatch warning is not useful for
checking the committed files globally since large number of files still
have no SPDX tag.
Also, I am not sure about the legal effect when the SPDX tag is broken.
Anyway, these typos are absolutely worth fixing. It is pretty easy to
find suspicious lines by grep.

Pull USB/PHY updates from Greg KH:
"Here is the big set of USB and PHY driver patches for 5.2-rc1
There is the usual set of:
- USB gadget updates
- PHY driver updates and additions
- USB serial driver updates and fixes
- typec updates and new chips supported
- mtu3 driver updates
- xhci driver updates
- other tiny driver updates
Nothing really interesting, just constant forward progress.
All of these have been in linux-next for a while with no reported
issues. The usb-gadget and usb-serial trees were merged a bit "late",
but both of them had been in linux-next before they got merged here
last Friday"
