Intel Cherry Trail Whiskey Cove extcon driver connect USB data lines to PMIC at driver probing for further charger detection. This causes reset of USB data sessions and removing all devices from bus. If system was booted from Live CD or USB dongle, this makes system unusable.
Check if USB ID pin is floating and re-route data lines in this case only, don't touch otherwise.

As of commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL"), the cht_bsw_rt5645 driver needs to enable the clock it's using for the codec's mclk. It does this from commit 7735bce05a9c ("ASoC: Intel: boards: use devm_clk_get() unconditionally"), enabling pmc_plt_clk_3. However, Strago family Chromebooks use pmc_plt_clk_0 for the codec mclk, resulting in white noise with some digital microphones. Add a DMI-based quirk for Strago family Chromebooks to use pmc_plt_clk_0 instead - mirroring the changes made to cht_bsw_max98090_ti in commit a182ecd3809c ("ASoC: intel: cht_bsw_max98090_ti: Add quirk for boards using pmc_plt_clk_0") and making use of the existing dmi_check_system() call and related infrastructure added in commit 22af29114eb4 ("ASoC: Intel: cht-bsw-rt5645: add quirks for SSP0/AIF1/AIF2 routing").

Due to a quirky C syntax of declaring pointers to array or function prototype, existing __type() macro doesn't work with map key/value types that are array or function prototype. One has to create a typedef first and use it to specify key/value type for a BPF map. By using typeof(), pointer to type is now handled uniformly for all kinds of types. Convert one of self-tests as a demonstration.

This patch adds a quirk disabling keyboard backlight support for the Dell Inspiron 1012 and 1018.
Those models wrongly report supporting keyboard backlight control features (through SMBIOS tokens) even though they're not equipped with a backlit keyboard. This led to broken controls being exposed through sysfs by this driver which froze the system when used.

Commit 5cca30ebe089be23 ("drm/rcar-du: Add LVDS_LANES quirk") states that LVDS lanes 1 and 3 are inverted on R-Car H2 ES1 only, and that the problem has been fixed in newer revisions.
However, the code didn't take into account the actual hardware revision, thus applying the quirk also on newer hardware revisions, causing green color reversals.
Fix this by applying the quirk when running on R-Car H2 ES1.x only.

Intel Visual Compute Accelerator (VCA) is a family of PCIe add-in devices exposing computational units via Non Transparent Bridges (NTB, PEX 87xx).
Similarly to MIC x200, we need to add DMA aliases to allow buffer access when IOMMU is enabled.
Add aliases to allow computational unit access to host memory. These aliases mark the whole VCA device as one IOMMU group.
All possible slot numbers (0x20) are used, since we are unable to tell what slot is used on other side. This quirk is intended for both host and computational unit sides. The VCA devices have up to five functions: four for DMA channels and one additional.

Non-Transparent Bridge (NTB) devices (among others) may have many DMA aliases seeing the hardware will send requests with different device ids depending on their origin across the bridged hardware.
See commit ad281ecf1c7d ("PCI: Add DMA alias quirk for Microsemi Switchtec NTB") for more information on this.
The AMD IOMMU ignores all the PCI aliases except the last one so DMA transfers from these aliases will be blocked on AMD hardware with the IOMMU enabled.
To fix this, ensure the DTEs are cloned for every PCI alias. This is done by copying the DTE data for each alias as well as the IVRS alias every time it is changed.

See commit ad281ecf1c7d ("PCI: Add DMA alias quirk for Microsemi Switchtec NTB") for more information on this.
The AMD IOMMU IRQ remapping functionality ignores all PCI aliases for IRQs so if devices send an interrupt from one of their aliases they will be blocked on AMD hardware with the IOMMU enabled.
To fix this, ensure IRQ remapping is enabled for all aliases with MSI interrupts.
This is analogous to the functionality added to the Intel IRQ remapping code in commit 3f0c625c6ae7 ("iommu/vt-d: Allow interrupts from the entire bus for aliased devices")

It turned out Intel Gemini Lake doesn't use the same I2C timing parameters as Broxton.
I got confirmation from the Windows team that Gemini Lake systems should use updated timing parameters that differ from those used in Broxton based systems.

AMD SDHC 0x7906 requires a hard reset to clear all internal state. Otherwise it can get into a bad state where the DATA lines are always read as zeros.
This change requires firmware that can transition the device into D3Cold for it to work correctly. If the firmware does not support transitioning to D3Cold then the power state transitions are a no-op.

v4.11-rc1 did introduce a patch series that rearranged the sdio quirks into a header file. Unfortunately this did forget to handle SDIO_VENDOR_ID_TI differently between wl1251 and wl1271 with the result that although the wl1251 was found on the sdio bus, the firmware did not load any more and there was no interface registration.
This patch defines separate constants to be used by sdio quirks and drivers.

We need to use forced idle mode for both SYSC_QUIRK_SWSUP_MSTANDBY and SYSC_QUIRK_FORCE_MSTANDBY, but SYSC_QUIRK_SWSUP_MSTANDBY also need to additionally also configure no-idle mode when enabled.

The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad which is connected to an ITE 8595 USB keyboard controller chip.
This keyboard has the same quirk for its rfkill / airplane mode hotkey as other keyboards with the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event.
This commit adds this keyboards USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard.
