2020-02-12dma: pxp: enable pxp clocks before soft resetPhilippe Schenker
pxp_soft_reset is writing to registers that are not clocked and then resulting in a lockup. Interestingly I could only see this behaviour when starting a kernel using kexec. This could have something to do with how u-boot enables clocks on a regular boot. In this commit this gets fixed with enabling the clocks before doing a pxp_soft_reset.

2020-02-12spi: fsl-lpspi: register spi controller earlier in probePhilippe Schenker
Ordering of stuff in lpspi probe was a little off. - num_chipselect gets set with devm_spi_register_controller. - devm_spi_register_controller needs data that gets set into controller variable Order stuff appropriate so num_chipselect gets set before it is used.

2020-02-12rpmsg: virtio rpmsg: Add RPMsg char driver supportIgor Opaniuk
virtio rpmsg was not implemented to use RPMsg char driver. Each virtio ns announcement will create a new RPMsg device which is supposed to bound to a RPMsg driver. It doesn't support dynamic endpoints with name service per RPMsg device. With RPMsg char driver, you can have multiple endpoints per RPMsg device. Here is the change from this patch: * Introduce a macro to indicate if want to use RPMsg char driver for virtio RPMsg. The RPMsg device can either be bounded to a simple RPMsg driver or the RPMsg char driver. * Create Virtio RPMsg char device when the virtio RPMsg driver is probed. * when there is a remote service announced, keep it in the virtio proc remote services list. * when there is an endpoint created, bind it to a remote service from the remote services list. If the service doesn't exist yet, create one and mark the service address as ANY. That patch ported to our 4.14 kernel + additional fixes added [1]. Example of usage from userspace app: ``` char data_buf [] = {'a', 'b', 'c', 'd', '\0'}; struct rpmsg_endpoint_info ept_info = {"rpmsg-openamp-demo-channel", 0x2, 0x1}; int fd = open("/dev/rpmsg_ctrl0", O_RDWR); /* create endpoint interface */ ioctl(fd, RPMSG_CREATE_EPT_IOCTL, &ept_info); /* create endpoint */ int fd_ept = open("/dev/rpmsg0", O_RDWR); /* receive data from remote device */ read(fd_ept, &data_buf, sizeof(data_buf)); /* send data to remote device */ write(fd_ept, &data_buf, sizeof(data_buf)); /* destroy endpoint */ ioctl(fd_ept, RPMSG_DESTROY_EPT_IOCTL); close(fd_ept); close(fd); ``` [1] https://patchwork.kernel.org/patch/10145779/ Signed-off-by: Wendy Liang <jliang@xilinx.com> Signed-off-by: Igor Opaniuk <igor.opaniuk@toradex.com>

2020-02-12arm64: dts: freescale: add initial support for verdin imx8mmMax Krummenacher
This patch adds the device tree to support Toradex Verdin iMX8M Mini a computer on module which can be used on different carrier boards. The module consists of an NXP i.MX 8M Mini family SoC, a Rohm BD71847 PMIC, a Gigabit Ethernet PHY, 2 GB of LPDDR4 RAM, an eMMC, an ADC, a Secure Element, an EEPROM, an RTC, USB host and OTG ports, PCIe and MIPI-CSI2/DSI interfaces plus optional Bluetooth/Wi-Fi module and CAN controllers. Anything that is not self-contained on the module is disabled by default. The device tree for the Verdin Development Board includes the module's device tree and enables the supported peripherals of the carrier board (the Verdin Development Board supports almost all of them). Not yet tested: - all UARTs other than console/debug Verdin UART_3 - push button controller on carrier board - JTAG - I2S to Wi-Fi - I2S to DSI Mezzanine Not yet working: - carrier board audio - MIPI-CSI2 - carrier board power gating - FTDI control signals and JTAG Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
