* usb: renesas_usbhs: Revise the binding document about the dma-namesYoshihiro Shimoda2015-05-26
| | | | | | | | | | | | | | Since the DT should describe the hardware (not the driver limitation), This patch revises the binding document about the dma-names to change simple numbering as "ch%d" instead of "tx<n>" and "rx<n>". Also this patch fixes the actual code of renesas_usbhs driver to handle the new dma-names.

| * dt-bindings: brcm: rationalize Broadcom documentation namingScott Branden2015-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patchset attempts to standardize the naming of dt-bindings documents based on the Broadcom vendor prefix of brcm. Although there are no guidelines currently present for how to name the dt-bindings document the "vendor,binding.txt" style is in use by some of the other vendors.

USB3 LPM (Link Power Management) capability is hardware property, and it's platform dependent, so if our hardware supports this feature, we want rather to configure it in devicetree than having it as Kconfig option.

The nvidia,tegra20-timer compatible string is removed from the nvidia,tegra30-timer.txt documentation file because it's already mentioned in the nvidia,tegra20-timer.txt documentation file. This second version takes into account the following requests from Rob Herring <robherring2@gmail.com>: - Per-IP block patches have been combined into a single patch - Explicit documentation about which compatible strings are actually matched by the driver has been removed. In its place is implicit documentation that loosely follows Rob's prescribed format: "Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ..."

Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux. Thanks for Tony Lindgren's work, we can now have a distro-like kernel where all MUSB glue layers can be built into the same kernel (statically or dynamically linked) and it'll work in PIO (DMA will come probably on v3.20).

In device mode it adds the capability to send NYET response threshold based on the BESL value received in the LPM token, and the threhold is configurable for each soc platform. This patch adds an entry that soc platform is able to define the lpm capacity with their own device tree or bus glue layer. [ balbi@ti.com : added devicetree documentation, spelled threshold completely, made sure threshold is only applied to proper core revisions. ] Signed-off-by: Huang Rui <ray.huang@amd.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | This adds Vybrid VF610 SoC support. The IP is very similar to i.MX6, however, the non-core registers are spread in two different register areas. Hence we support multiple instances of the USB misc driver and add the driver instance to the imx_usbmisc_data structure.

Audio and UVC gadgets can now be used with our configfs-based binding. We have three PHY drivers being removed because a new one has been added using new PHY framework. Gadget framework got a new ->reset callback preparing for some other changes to come on next merge window. A few new drivers came in as well; among those we have a new UDC driver from Xilinx and two new glue layers for DWC3 (ST and Qualcomm). DWC3 also learned about tracepoints which will help debugging quite a bit. Other than that, a big series of non-critical fixes and cleanups. All patches have been on linux-next for quite a bit of time and I boot tested these changes on platforms I have access to and work with mainline. Signed-of-by: Felipe Balbi <balbi@ti.com>

We assume that the disconnection without VBUS is also needed for Vybrid. Tests showed, without MXS_PHY_NEED_IP_FIX, enumeration of devices behind a USB Hub fails with errors: [ 215.163507] usb usb1-port1: cannot reset (err = -32) [ 215.170498] usb usb1-port1: cannot reset (err = -32) [ 215.185120] usb usb1-port1: cannot reset (err = -32) [ 215.191345] usb usb1-port1: cannot reset (err = -32) [ 215.202487] usb usb1-port1: cannot reset (err = -32) [ 215.207718] usb usb1-port1: Cannot enable. Maybe the USB cable is bad? [ 215.219317] usb usb1-port1: unable to enumerate USB device Hence we also enable the MXS_PHY_NEED_IP_FIX flag.
