The driver shouldn't be able to issue End Transfer to the control endpoint at anytime. Typically we should only do so in error cases such as invalid/unexpected direction of Data Phase as described in the control transfer flow of the programming guide. It _may_ end started data phase during controller deinitialization from soft disconnect or driver removal. However, that should not happen because the driver should be maintained in EP0_SETUP_PHASE during driver tear-down. On soft-connect, the controller should be reset from a soft-reset and there should be no issue starting the control endpoint.

Since we can't guarantee that the host won't send new Setup packet before going through the device-initiated disconnect, don't prepare beyond the Setup stage and keep the device in EP0_SETUP_PHASE. This ensures that the device-initated disconnect sequence can go through gracefully. Note that the controller won't service the End Transfer command if it can't DMA out the Setup packet.

If the GEVNTCOUNT indicates events in the event buffer, the driver needs to acknowledge them before the controller can halt. Simply let the interrupt handler acknowledges the remaining event generated by the controller while polling for DSTS.DEVCTLHLT. This avoids disabling irq and taking care of race condition between the interrupt handlers and pullup().

Don't do soft-disconnect if it's previously done. Likewise, don't do soft-connect if the device is currently connected and running. It would break normal operation. Currently the caller of pullup() (udc's sysfs soft_connect) only checks if it had initiated disconnect to prevent repeating soft-disconnect. It doesn't check for soft-connect. To be safe, let's keep the check here regardless whether the udc core is fixed.

This patch adds a USB GPIO based reset for dwc3-xilinx driver. The PHY needs to be reset after the completion of phy initialization. As part of the reset, check for gpio-reset binding before toggling the pin. This feature is advantageous when the user toggle GPIO to trigger the ULPI-PHY reset. Delay of milliseconds is added in between low and high to meet the setup and hold time requirement of the reset. The reset-gpio error handling is added for error notification. Some GPIO controllers must be accessed using message-based buses, like I2C or SPI, to address this problem, updates GPIO access with sleep API. This reset is specific to the zynqMp.

It is no longer needed. The sysdev pointer is now used when assigning the ACPI companions to the xHCI ports and USB devices. Assigning the ACPI companion here resulted in the fwnode->secondary pointer to be replaced also for the parent dwc3 device since the primary fwnode (the ACPI companion) was shared. That was unintentional and it created potential side effects like resource leaks.

Currently when driver->match_existing_only is true, the error return is set to -EBUSY however ret is then set to 0 at the end of the if/else statement.

Pull clk fixes from Stephen Boyd: "A semi-large pile of clk driver fixes this time around. Nothing is touching the core so these fixes are fairly well contained to specific devices that use these clk drivers. - Some Allwinner SoC fixes to gracefully handle errors and mark an RTC clk as critical so that the RTC keeps ticking. - Fix AXI bus clks and RTC clk design for Microchip PolarFire SoC driver introduced this cycle. This has some devicetree bits acked by riscv maintainers. We're fixing it now so that the prior bindings aren't released in a major kernel version. - Remove a reset on Microchip PolarFire SoCs that broke when enabling CONFIG_PM. - Set a min/max for the Qualcomm graphics clk. This got broken by the clk rate range patches introduced this cycle" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: sunxi: sun9i-mmc: check return value after calling platform_get_resource() clk: sunxi-ng: sun6i-rtc: Mark rtc-32k as critical riscv: dts: microchip: reparent mpfs clocks clk: microchip: mpfs: add RTCREF clock control clk: microchip: mpfs: re-parent the configurable clocks dt-bindings: rtc: add refclk to mpfs-rtc dt-bindings: clk: mpfs: add defines for two new clocks dt-bindings: clk: mpfs document msspll dri registers riscv: dts: microchip: fix usage of fic clocks on mpfs clk: microchip: mpfs: mark CLK_ATHENA as critical clk: microchip: mpfs: fix parents for FIC clocks clk: qcom: clk-rcg2: fix gfx3d frequency calculation clk: microchip: mpfs: don't reset disabled peripherals clk: sunxi-ng: fix not NULL terminated coccicheck error

This reverts commit 0dc23d1a, which caused another regression as the pinctrl code actually expects an integer value of 0 or 1 rather than a simple boolean property. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Synthesizing AMD leaves up to 0x80000021 caused problems with QEMU, which assumes the *host* CPUID[0x80000000].EAX is higher or equal to what KVM_GET_SUPPORTED_CPUID reports. This causes QEMU to issue bogus host CPUIDs when preparing the input to KVM_SET_CPUID2. It can even get into an infinite loop, which is only terminated by an abort(): cpuid_data is full, no space for cpuid(eax:0x8000001d,ecx:0x3e) To work around this, only synthesize those leaves if 0x8000001d exists on the host. The synthetic 0x80000021 leaf is mostly useful on Zen2, which satisfies the condition. Fixes: f144c49e ("KVM: x86: synthesize CPUID leaf 0x80000021h if useful") Reported-by: Maxim Levitsky <mlevitsk@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
