drivers/net/phy: add fixed-phy / fixed-link support

2017-03-26T14:58:26Z

This patch adds support for having a "fixed-link" to some other MAC (like some embedded switch-device). For this purpose we introduce a new phy-driver, called "Fixed PHY". Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is described with a subnode below ethernet interface. Most ethernet drivers (unfortunately not all are following same scheme for searching/attaching phys) are calling "phy_connect(...)" for getting a phy-device. At this point we link in, we search here for a subnode called "fixed- link", once found we start phy_device_create(...) with the special phy- id PHY_FIXED_ID (0xa5a55a5a). During init the "Fixed PHY" driver has registered with this id and now gets probed, during probe we get all the details about fixed-link out of dts, later on the phy reports this values.

This replaces legacy arch/arc/lib/timer.c implementation and allows us to describe ARC Timers in Device Tree. Among other things that way we may properly inherit Timer's clock from CPU's clock s they really run synchronously.

drivers: timer: Introduce ARC timer driver

2017-03-24T11:20:55Z

This commit introduces timer driver for ARC. ARC timers are configured via ARC AUX registers so we use special functions to access timer control registers. This driver allows utilization of either timer0 or timer1 depending on which one is available in real hardware. Essentially only existing timers should be mentioned in board's Device Tree description. Signed-off-by: Vlad Zakharov Reviewed-by: Simon Glass

dm: Add callback to modify the device tree

2017-03-23T14:46:23Z

Certain boards come in different variations by way of utilizing daughter boards, for example. These boards might contain additional chips, which are added to the main board's busses, e.g. I2C. The device tree support for such boards would either, quite naturally, employ the overlay mechanism to add such chips to the tree, or would use one large default device tree, and delete the devices that are actually not present. Regardless of approach, even on the U-Boot level, a modification of the device tree is a prerequisite to have such modular families of boards supported properly. Therefore, we add an option to make the U-Boot device tree (the actual copy later used by the driver model) writeable, and add a callback method that allows boards to modify the device tree at an early stage, at which, hopefully, also the application of device tree overlays will be possible.

mvebu: usb: xhci: Add VBUS regulator supply to the host driver

2017-03-23T07:45:25Z

The USB device should linked to VBUS regulator through "vbus-supply" DTS property. This patch adds handling for "vbus-supply" property inside the USB device entry for turning on the VBUS regulator upon the host adapter probe.
