2019-02-25misc/mei/hdcp: Client driver for HDCP applicationRamalingam C
ME FW contributes a vital role in HDCP2.2 authentication. HDCP2.2 driver needs to communicate to ME FW for each step of the HDCP2.2 authentication. ME FW prepare and HDCP2.2 authentication parameters and encrypt them as per spec. With such parameter Driver prepares HDCP2.2 auth messages and communicate with HDCP2.2 sink. Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and verification. Once All the steps of HDCP2.2 authentications are complete on driver's request ME FW will configure the port as authenticated and supply the HDCP keys to the Gen HW for encryption. Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption for a port. ME FW is interfaced to kernel through MEI Bus Driver. To obtain the HDCP2.2 services from the ME FW through MEI Bus driver MEI Client Driver is developed. v2: hdcp files are moved to drivers/misc/mei/hdcp/ [Tomas] v3: Squashed the Kbuild support [Tomas] UUID renamed and Module License is modified [Tomas] drv_data is set to null at remove [Tomas] v4: Module name is changed to "MEI HDCP" I915 Selects the MEI_HDCP v5: Remove redundant text from the License header Fix malformed licence Removed the drv_data resetting. v6: K-Doc addition.

2019-02-25ALSA: hda: Extend i915 component bind timeoutTakashi Iwai
I set 10 seconds for the timeout of the i915 audio component binding with a hope that recent machines are fast enough to handle all probe tasks in that period, but I was too optimistic. The binding may take longer than that, and this caused a problem on the machine with both audio and graphics driver modules loaded in parallel, as Paul Menzel experienced. This problem haven't hit so often just because the KMS driver is loaded in initrd on most machines. As a simple workaround, extend the timeout to 60 seconds.

2019-02-25mmc: spi: Fix card detection during probeJonathan Neuschäfer
When using the mmc_spi driver with a card-detect pin, I noticed that the card was not detected immediately after probe, but only after it was unplugged and plugged back in (and the CD IRQ fired). The call tree looks something like this: mmc_spi_probe mmc_add_host mmc_start_host _mmc_detect_change mmc_schedule_delayed_work(&host->detect, 0) mmc_rescan host->bus_ops->detect(host) mmc_detect _mmc_detect_card_removed host->ops->get_cd(host) mmc_gpio_get_cd -> -ENOSYS (ctx->cd_gpio not set) mmc_gpiod_request_cd ctx->cd_gpio = desc To fix this issue, call mmc_detect_change after the card-detect GPIO/IRQ is registered.

2019-02-25mmc: mmci: Send a CMD12 to clear the DPSM at errorsUlf Hansson
The current approach with sending a CMD12 (STOP_TRANSMISSION) to complete a data transfer request, either because of using the open-ended transmission type or because of receiving an error during a pre-defined data transfer, isn't sufficient for the STM32 sdmmc variant. More precisely, this variant needs to clear the DPSM ("Data Path State Machine") by sending a CMD12, for all failing ADTC commands. Support this, by adding a struct mmc_command inside the struct mmci_host and initialize it to a CMD12 during ->probe(). Let's also add checks for the new conditions, to enable mmci_data_irq() and mmci_cmd_irq() to postpone the calls to mmci_request_end(), but instead send the CMD12.

2019-02-25mmc: sdhci: use WP GPIO in sdhci_check_ro()Thomas Petazzoni
Even though SDHCI controllers may have a dedicated WP pin that can be queried using the SDHCI_PRESENT_STATE register, some platforms may chose to use a separate regular GPIO to route the WP signal. Such a GPIO is typically represented using the wp-gpios property in the Device Tree. Unfortunately, the current sdhci_check_ro() function does not make use of such GPIO when available: it either uses a host controller specific ->get_ro() operation, or uses the SDHCI_PRESENT_STATE. Several host controller specific ->get_ro() functions are implemented just to check a WP GPIO state. Instead of pushing this to more controller-specific implementations, let's handle this in the core SDHCI code, just like it is already done for the CD GPIO in sdhci_get_cd(). The below patch simply changes sdhci_check_ro() to use the value of the WP GPIO if available.
