2018-12-02usb: Do not compile USB_STORAGE with BLK && !DM_USBAlexander Graf
The USB storage driver does not compile when CONFIG_BLK is set, but DM_USB is not set, as we're missing the DM device links for CONFIG_BLK enabled code paths. So far it looks like nobody fell into this trap, because no board enabled CONFIG_BLK and CONFIG_USB_STORAGE while not enabling CONFIG_DM_USB, but we should still reflect that dependency properly in Kconfig so that implicit enabling of CONFIG_USB_STORAGE works.

2018-12-02efi_loader: PSCI reset and shutdownHeinrich Schuchardt
When an operating system started via bootefi tries to reset or power off this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system the actual reset relies on PSCI. Depending on whether the PSCI firmware resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC or an SMC command has to be issued. The current implementation always uses SMC. This results in crashes on systems where the PSCI firmware is implemented in the hypervisor, e.g. qemu-arm64_defconfig. The logic to decide which call is needed based on the device tree is already implemented in the PSCI firmware driver. During the EFI runtime the device driver model is not available. But we can minimize code duplication by merging the EFI runtime reset and poweroff code with the PSCI firmware driver. As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff and reset_misc routines let's move them into the same code module.

2018-11-30rockchip: rk3399: Initialize CPU B clock.Christoph Muellner
This patch sets the PLL of CPU cluster B (BPLL) to 600 MHz. This decreases the boot time of Linux 4.19 by about 8%. The 600 MHz are inspired by the 600 MHz used for LPLL initialization (came in with commit 9f636a249c1). Tested on RK3399-Q7 on Haikou base board.

The "Flamingo" carrier-board for the RK3399-Q7 has a RV3029 populated and the application will use the off-module RV3029 RTC including the battery backed SRAM. To support this use case, this commit includes the following changes: * updates the rv3029 driver to use DM * implements the read8/write8 operations This syncs the implementation with the Linux code (based on 4.17), porting the trickle-charger support from there (with improvements to avoid unnecessary EEPROM updates) and adheres to the Linux DTS binding.

2018-11-29dm: sandbox: i2c: Add a new 'emulation parent' uclassSimon Glass
Sandbox i2c works using emulation drivers which are currently children of the i2c device: rtc_0: rtc@43 { reg = <0x43>; compatible = "sandbox-rtc"; emul { compatible = "sandbox,i2c-rtc"; }; }; In this case the emulation device is attached to i2c bus on address 0x43 and provides the Real-Time-Clock (RTC) functionality. However this is not ideal, since every device on an I2C bus has a child device. This is only really the case for sandbox, but we want to avoid special-case code for sandbox. A better approach seems to be to add a separate node on the bus, an 'emulation parent'. This can be given a bogus address (such as 0xff) and hides all the emulators away. Then we can use a phandle to point from the device to the correct emualtor, and only on sandbox. The code to find an emulator does not interfere with normal i2c operation. Add a new UCLASS_I2C_EMUL_PARENT uclass which allows finding an emulator given a bus, and finding a bus given an emulator. This will be used in a follow-on patch.

2018-11-29gpio: dwapb_gpio: fix binding without bank-name propertySimon Goldschmidt
As a preparation for merging the socfpga gen5 devicetree files from Linux, this patch makes the dwapb gpio driver work correctly without the 'bank-name' property on the gpio-controller nodes. This property is not present in the Linux drivers and thus is not present in the Linux devicetrees. It is only used to access pins via bank name. This fallback is necessary since without it, the driver will return an error code which will lead to an error in U-Boot startup. The bank names will still be added to the default board device trees in follow-up patch, but other boards using this driver and not including the bank name should also work with the socfpga.dtsi without adding the bank-name property.

Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode.
