Sivaprakash Murugesan afd55e6d1b phy: qcom-qmp: Use correct values for ipq8074 PCIe Gen2 PHY init
There were some problem in ipq8074 Gen2 PCIe phy init sequence.

1. Few register values were wrongly updated in the phy init sequence.
2. The register QSERDES_RX_SIGDET_CNTRL is a RX tuning parameter
   register which is added in serdes table causing the wrong register
   was getting updated.
3. Clocks and resets were not added in the phy init.

Fix these to make Gen2 PCIe port on ipq8074 devices to work.

regfield handling in current driver code is made complicated

This quickly gets unwieldy once number of regfields increase.

Russell King 1dea06cd64 phy: armada-38x: fix NETA lockup when repeatedly switching speeds
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".

Yoshihiro Shimoda 08b0ad375c phy: renesas: rcar-gen3-usb2: move irq registration to init
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 549b6b55b0 ("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.

Anurag Kumar Vulisha 4a33bea003 phy: zynqmp: Add PHY driver for the Xilinx ZynqMP Gigabit Transceiver
Xilinx ZynqMP SoCs have a Gigabit Transceiver with four lanes. All the
high speed peripherals such as USB, SATA, PCIE, Display Port and
Ethernet SGMII can rely on any of the four GT lanes for PHY layer. This
patch adds driver for that ZynqMP GT core.

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.

Bharat Gooty 6f0577d141 drivers: phy: sr-usb: do not use internal fsm for USB2 phy init
During different reboot cycles, USB PHY PLL may not always lock
during initialization and therefore can cause USB to be not usable.

Hence do not use internal FSM programming sequence for the USB
PHY initialization.

Bjorn Andersson 72f039db49 phy: qcom-qmp: Ensure register indirection arrays initialized
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.

their PHY code). While here, also add all other REG_DBG_UART register

The USB phy takes some time to reset, so make sure we give it to it. The
delay length was taken from the 4x12 phy driver.

This manifested in issues with the DWC2 driver since commit fe369e1826
("usb: dwc2: Make dwc2_readl/writel functions endianness-agnostic.")
where the endianness check would read the DWC ID as 0 due to the phy still
resetting, resulting in the wrong endian mode being chosen.
