2018-12-18drivers: serial: Add SiFive UART driverAnup Patel
This patch adds SiFive UART driver. The driver is 100% DM driver and it determines input clock using clk framework. Signed-off-by: Anup Patel <anup@brainfault.org> Reviewed-by: Palmer Dabbelt <palmer@sifive.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
2018-12-18timer: Add generic driver for RISC-V privileged architecture defined timerBin Meng
RISC-V privileged architecture v1.10 defines a real-time counter, exposed as a memory-mapped machine-mode register - mtime. mtime must run at constant frequency, and the platform must provide a mechanism for determining the timebase of mtime. The mtime register has a 64-bit precision on all RV32, RV64, and RV128 systems. Different platform may have different implementation of the mtime block hence an API riscv_get_time() is required by this driver for platform codes to hide such implementation details. For example, on some platforms mtime is provided by the CLINT module, while on some other platforms a simple 'rdtime' can be used to get the timer counter. With this timer driver the U-Boot timer functionalities like delay works correctly now.

When the device is in peripheral mode there is no struct usb_bus_priv allocated pointer, as the uclass driver ("usb_dev_generic") doesn't call per_device_auto_alloc_size.

2018-12-14usb: composite: Fix max packet size for USB3.0Siva Durga Prasad Paladugu
For USB3.0, the max packetsize for GET_DESCRIPTOR should be sent as exponent value for 2. This means for 512, max packet size should be filled with 9(2^9=512). Also, fill the USB version field with 3.0 if speed is negotiated to Superspeed. This fixes the issue of DFU gadget download failure with superspeed. Without this patch, the max packet size is overflowed to zero as the bMaxPacketsize is of u8 and hence host is not able to detect this device.

2018-12-14usb: musb-new: Add support for DM_USBJean-Jacques Hiblot
Enable DM for USB peripheral in the musb-new driver. Also make sure that the driver can be used in the SPL. This implies that: * the driver must work with and without the OF_CONTROL option. That in turn, implies that the platform data can be passed in a struct ti_musb_platdata or be read from the dtb * usb.o is linked in the SPL if host support is enabled Another change is that the driver does not fail to bind (and stop the boot process) if one of the child driver does not bind. Reporting the error is enough. This kind of error would appear if the port is configured in the DTS but the driver is not activated in the config.

2018-12-14usb: Don't enable CONFIG_SPL_DM_USB for non-DM SPLMartyn Welch
When CONFIG_SPL_DM_USB was added, it was added defaulted on without protection to ensure it didn't get set for non-DM SPL builds. This leads to unexpected and confusing failures when building a DM based U-Boot but with a non-DM SPL, as the defconfig is unlikely to have CONFIG_SPL_DM_USB actively disabled.
