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.

2020-07-21phy: armada-38x: fix NETA lockup when repeatedly switching speedsRussell King1-7/+38
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.

2020-07-20phy: renesas: rcar-gen3-usb2: move irq registration to initYoshihiro Shimoda1-28/+33
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.

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.
