2019-11-12usb: dwc3: Allow disabling of metastability workaroundRoger Quadros
commit 42bf02ec6e420e541af9a47437d0bdf961ca2972 upstream Some platforms (e.g. TI's DRA7 USB2 instance) have more trouble with the metastability workaround as it supports only a High-Speed PHY and the PHY can enter into an Erratic state [1] when the controller is set in SuperSpeed mode as part of the metastability workaround. This causes upto 2 seconds delay in enumeration on DRA7's USB2 instance in gadget mode. If these platforms can be better off without the workaround, provide a device tree property to suggest that so the workaround is avoided.

Implement mode_valid and check functions from drm_simple_display_pipe_funcs such that we can filter-out modes that cannot be driven by this controller. Add 3 new clocks: - video_pll: this is the PLL that provides the pixel clock; it's rate needs to be set such that the pixel clock can be achieved - osc_25: this is an oscillater that can be used as source clock for the video_pll; default freq is 25MHz - osc_27: same as above, but with freq of 27MHz Depending on the display mode used, the video_pll needs to have it's clock source a 25MHz or 27MHz oscillator. Also, the video_pll rate needs to be set to a rate that can be evenly divided to obtain the required pixel clock. All these settings (clock source and video_pll rate) are saved in mode_valid, then applied before mode needs to be set in the check function.

This patch is to add CAN wakeup function on MX8 platforms and update the binding file fsl-flexcan.txt. For MX8, the function "flexcan_irq()" should not call "flexcan_exit_stop_mode()" due to firmware(SCU) cannot make SC IPC calls from an interrupt context. If not exit stop mode in ISR, it will continuously enter wakeup ISR for the reason that system will respond IRQ before call CAN system resume.

2019-02-12MLK-19042-1: ASoC: fsl_rpmsg_i2s: support low power audioShengjiu Wang
Add two new message command I2S_TX_POINTER and I2S_RX_POINTER, which are used to get the hw pointer in m4 side. For in low power audio mode, m4 won't send notification every period, the notification only be sent when hw pointer reach end of buffer, so we need these command to get the position of hw pointer, user can use it to calculate the timestamp. Restructure send message and recv message together for i2s_rpmsg, that every send message has a recv message. so the i2s_send_message can store the recv message indepedently. one reason is that the receive message is async withe send message. The low power audio is disabled in default, user need to enabled it by add "fsl,enable-lpa" in dts.
