2021-05-19drm/amd/display: Disconnect non-DP with no EDIDChris Park1-0/+18
[Why] Active DP dongles return no EDID when dongle is connected, but VGA display is taken out. Current driver behavior does not remove the active display when this happens, and this is a gap between dongle DTP and dongle behavior. [How] For active DP dongles and non-DP scenario, disconnect sink on detection when no EDID is read due to timeout.

[why] As per spec, DCN3.x can do 6:1 downscaling and DCN2.x can do 4:1. The max downscaling limit value for DCN2.x is 250, which means it's calculated as 1000 / 4 = 250.

2021-05-19pata_octeon_cf: avoid WARN_ON() in ata_host_activate()Sergey Shtylyov1-2/+3
Iff platform_get_irq() fails (or returns IRQ0) and thus the polling mode has to be used, ata_host_activate() hits the WARN_ON() due to 'irq_handler' parameter being non-NULL if the polling mode is selected. Let's only set the pointer to the driver's IRQ handler if platform_get_irq() returns a valid IRQ # -- this should avoid the unnecessary WARN_ON()...

2021-05-19mlxsw: spectrum_router: Add support for inner layer 3 multipath hash policyIdo Schimmel1-0/+41
When this policy is set, the kernel uses the inner layer 3 fields for multipath hash computation and falls back to the outer fields if no encapsulation was encountered. This behavior is most likely influenced by the behavior of the flow dissector, which is used for the packet dissection. The Spectrum ASIC, however, cannot fallback to outer fields if inner fields are not available. This should not result in a discrepancy from the software data path because if several flows have matching inner fields, they will tend to have matching outer fields as well. Therefore, implement this policy by enabling both outer and inner layer 3 fields for the multipath hash computation.

2021-05-19nfc: s3fwrn5: i2c: Enable optional clock from device treeStephan Gerhold1-2/+28
S3FWRN5 depends on a clock input ("XI" pin) to function properly. Depending on the hardware configuration this could be an always-on oscillator or some external clock that must be explicitly enabled. So far we assumed that the clock is always-on. Make the driver request an (optional) clock from the device tree and make sure the clock is running before starting S3FWRN5. Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to function correctly. On some hardware configurations, GPIO2 is connected directly to an input pin of the external clock provider (e.g. the main PMIC of the SoC). In that case, it can automatically AND the clock enable bit and clock request from S3FWRN5 so that the clock is actually only enabled when needed. It is also conceivable that on some other hardware configuration S3FWRN5's GPIO2 might be connected as a regular GPIO input of the SoC. In that case, follow-up patches could extend the driver to request the GPIO, set up an interrupt and only enable the clock when requested by S3FWRN5.

2021-05-19Merge series "RTL8231 GPIO expander support" from Sander Vanheule <sander@svanheule.net>:Mark Brown3-1/+63
The RTL8231 GPIO and LED expander can be configured for use as an MDIO or SMI bus device. Currently only the MDIO mode is supported, although SMI mode support should be fairly straightforward, once an SMI bus driver is available. Provided features by the RTL8231: - Up to 37 GPIOs - Configurable drive strength: 8mA or 4mA (currently unsupported) - Input debouncing on high GPIOs (currently unsupported) - Up to 88 LEDs in multiple scan matrix groups - On, off, or one of six toggling intervals - "single-color mode": 2×36 single color LEDs + 8 bi-color LEDs - "bi-color mode": (12 + 2×6) bi-color LEDs + 24 single color LEDs - Up to one PWM output (currently unsupported) - Fixed duty cycle, 8 selectable frequencies (1.2kHz - 4.8kHz) Register access is provided through a new MDIO regmap provider. The GPIO controller uses gpio-regmap, although a patch is required to support a limitation of the chip. There remain some log warnings when probing the device, possibly due to the way I'm using the MFD subsystem. Would it be possible to avoid these?

I was unable to resolve the Kconfig dependency issue, so have reverted to using regmap_config.reg_read/write. - Added pinctrl support - Added LED support - Changed root device to MFD, with pinctrl and leds child devices. Root device is now an mdio_device driver.
