ehci-ppc4xx: Prepare for usage of readl()/writel() accessors

2017-04-25T10:50:13+00:00

We used to have opencoded ehci_readl()/writel() which required no
external functions to be called.

Now with attempt to switch to generic readl()/writel() accessors
we see a missing declaration of those accessors in ehci-ppc4xx.
Something like that happens if applied

usb: dwc2: invalidate the dcache before starting the DMA

2017-04-14T14:44:16+00:00

We should invalidate the dcache before starting the DMA. In case there are
any dirty lines from the DMA buffer in the cache, subsequent cache-line
replacements may corrupt the buffer in memory while the DMA is still going on.
Cache-line replacement can happen if the CPU tries to bring some other memory
locations into the cache while the DMA is going on.

usb: dwc2: add support for external vbus supply

2017-04-14T12:07:46+00:00

Some board do not use the dwc2 internal VBUS_DRV signal, but
use a gpio pin to enable the 5.0V VBUS power, add interface to
enable the power in dwc2 driver.

sunxi: prepare for sharing MACH_SUN8I_H3 config symbol

2017-04-05T09:33:17+00:00

The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores.
To allow sharing the clocks, GPIO and driver code easily, create an
architecture agnostic MACH_SUNXI_H3_H5 Kconfig symbol.
Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10+00:00

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.

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

2017-03-23T07:45:25+00:00

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.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.
