clk: stm32mp1: correctly handle Clock Spreading Generator

2019-02-09T12:50:57Z

To activate the csg option, the driver need to set the bit2 of PLLNCR register = SSCG_CTRL: Spread Spectrum Clock Generator of PLLn enable. Signed-off-by: Patrick Delaunay

w1: Add driver for i.MX bus master controller

2019-01-01T13:12:18Z

Two variants of controllers are supported: V1 (bitwise only) found in i.MX21, i.MX27, i.MX31, i.MX51 V2 (byte operations) found in i.MX25, i.MX35, i.MX50, i.MX53 Only tested on i.MX53 hardware but in both modes (by modifying the device tree). Signed-off-by: Martin Fuzzey

power: add FAN53555 family support

2018-12-10T09:04:45Z

This adds a driver for the FAN53555 family of regulators and wraps it in a PMIC implementation. While these devices support a 'normal' and 'suspend' mode (controlled via an external pin) to switch between two programmable voltages, this incarnation of the driver assumes that the device is always operating in 'normal' mode. Only setting/reading the programmed voltage is supported at this time and the following device functionality remains unsupported: - switching the selected voltage (via a GPIO) - disabling the voltage output via software-control This matches the functionality of the Linux driver. Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from the U-Boot shell and verifying output voltages on the board. Signed-off-by: Philipp Tomsich Tested-by: Klaus Goger

bootcount: add uclass for bootcount

2018-12-10T09:04:44Z

The original bootcount methods do not provide an interface to DM and rely on a static configuration for I2C devices (e.g. bus, chip-addr, etc. are configured through defines statically). On a modern system that exposes multiple devices in a DTS-configurable way, this is less than optimal and a interface to DM-based devices will be desirable. This adds a simple driver that is DM-aware and configurable via DTS. If ambiguous (i.e. multiple bootcount-devices are present) the /chosen/u-boot,bootcount-device property can be used to select one bootcount device. Initially, this provides support for the following DM devices: * RTC devices Signed-off-by: Philipp Tomsich Tested-by: Klaus Goger

spi: cadence_qspi: use "cdns,qspi-nor" as compatible

2018-11-29T11:45:15Z

Linux uses "cdns,qspi-nor" as compatible string for the cadence qspi driver, so change driver, docs and all device trees. Signed-off-by: Simon Goldschmidt

ram: Introduce K3 AM654 DDR Sub System driver

2018-11-16T21:51:58Z

K3 based AM654 devices has DDR memory subsystem that comprises Synopys DDR controller, Synopsis DDR phy and wrapper logic to intergrate these blocks into the device. This DDR subsystem provides an interface to external SDRAM devices. Adding support for the initialization of the external SDRAM devices by configuring the DDRSS registers and using the buitin PHY routines.

net: Add MT7628 ethernet driver

2018-11-05T16:41:56Z

This patch adds ethernet support for the MIPS based Mediatek MT76xx SoCs (e.g. MT7628 and MT7688), including a minimum setup of the integrated switch. This driver is loosly based on the driver version included in this MediaTek github repository: https://github.com/MediaTek-Labs/linkit-smart-uboot.git Tested on the MT7688 LinkIt smart-gateway and on the Gardena-smart-gateway.

net: phy: ti: Add binding for the CLK_OUT pin muxing

2018-10-10T17:28:54Z

The DP83867 has a muxing option for the CLK_OUT pin. It is possible to set CLK_OUT for different channels. Create a binding to select a specific clock for CLK_OUT pin.
