2019-05-21phy: rockchip-emmc: Allow to set drive impedance via DTS.Christoph Muellner
The rockchip-emmc PHY can be configured with different drive impedance values. Currenlty a value of 50 Ohm is hard coded into the driver. This patch introduces the DTS property 'drive-impedance-ohm' for the rockchip-emmc phy node, which uses the value from the DTS to setup the drive impedance accordingly.

2018-05-09spi: Add Flag to Enable Slave Select with GPIO Chip Select.Thor Thayer
Some SPI masters require slave selection before the transfer can begin [1]. The SPI framework currently selects the chip using either 1) the internal CS mechanism or 2) the GPIO CS, but not both. This patch adds a new master->flags define to indicate both the GPIO CS and the internal chip select mechanism should be used.

The UCAN driver supports the microcontroller-based USB/CAN adapters from Theobroma Systems. There are two form-factors that run essentially the same firmware: * Seal: standalone USB stick ( https://www.theobroma-systems.com/seal ) * Mule: integrated on the PCB of various System-on-Modules from Theobroma Systems like the A31-µQ7 and the RK3399-Q7 ( https://www.theobroma-systems.com/rk3399-q7 ) The USB wire protocol has been designed to be as generic and hardware-indendent as possible in the hope of being useful for implementation on other microcontrollers.

During review of adding touchscreen-fw-name to the binding documentation it was brought up that there is a standard property name called "firmware-name" for this, which should be used. Since there are no users of touchscreen-fw-name yet, this commit adds documentation of "firmware-name" to the dt-binding documentation and switches the driver over to use this. This commit also makes the driver add a "silead/" prefix to the firmware name from dt before calling request_firmware. That the firmware files are stored under /lib/firmware/silead under Linux is an implementation detail and does not belong in devicetree.

This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. As pointed by Hans de Goede, there's no mssl1680 and this is just used in some ACPI systems to identify the gsl1680 chip. So isn't included in the OF device ID table since a DT should use the proper device name instead.

2018-04-26usb: dwc3: rockchip: fix usb peripheral connection failWilliam Wu
This patch fix the issue that usb peripheral fails to connect to PC after resume from deep sleep. In my test case, I use a rk3399 sapphire excavator board, and test usb as follows: - Let the system enter deep sleep without usb connection. - During deep sleep, connect the Type-C0 of rk3399 with PC usb port. - Press power key to wakeup system, and check if the PC can detect usb. Without this patch, the usb enumeration often fail with the error log "dwc3 fe800000.dwc3: failed to enable ep0out". It's because that after system resume, the dwc3 pm resume and dwc3 pm runtime resume are running asynchronously. If dwc3 runtime resume before pm resume, the dwc3_resume_common() maybe called twice, and cause ep enable failure. This patch use the suspend flag of dev to wait until the dwc3 core resume from PM suspend successfully before do dwc3 pm runtime resume.

2018-04-17drm/rockchip: update crtc->primary->fb only for hotplug device.Sandy Huang
For hotplug device the crtc->primary->fb should be equal to fb_helper->fb, otherwise the following path will return false and lead to connect state error: ->hotplug ->output_poll_changed() ->drm_fb_helper_hotplug_event() ->drm_fb_helper_is_bound() after user space beging, the above path can return false, because sometimes user space wants everything disabled, don't steal the display if there's a master, so we set crtc->primary->fb point to the original fb when drm_open.

2018-04-17drm/rockchip: update rockchip_drm_platform_shutdownSandy Huang
The reason to implement shutdown is for the fake shutdown on the box product. but after implement this function, panel will still display overlay plane for about two second when power off. so we directly close crtc instead of rockchip_drm_sys_suspend() when shutdown.
