Felipe writes: usb: patches for v3.20 merge window Here's the big pull request for Gadgets and PHYs. It's a total of 217 non-merge commits with pretty much everything being touched. The most important bits are a ton of new documentation for almost all usb gadget functions, a new isp1760 UDC driver, several improvements to the old net2280 UDC driver, and some minor tracepoint improvements to dwc3. Other than that, a big list of minor cleanups, smaller bugfixes and new features all over the place. Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-02-03Documentation: DT bindings: add more Tegra chip compatible stringsPaul Walmsley2-2/+8
Align compatible strings for several IP blocks present on Tegra chips with the latest doctrine from the DT maintainers: http://marc.info/?l=devicetree&m=142255654213019&w=2 The primary objective here is to avoid checkpatch warnings, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 DT binding text files have been updated for the following IP blocks: - PCIe - SOR - SoC timers - AHB "gizmo" - APB_MISC - pinmux control - UART - PWM - I2C - SPI - RTC - PMC - eFuse - AHCI - HDA - XUSB_PADCTRL - SDHCI - SOC_THERM - AHUB - I2S - EHCI - USB PHY N.B. 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, ..."

2015-01-12usb: atmel_usba_udc: Rework at91sam9rl errata handlingBoris Brezillon1-1/+4
at91sam9rl SoC has an erratum forcing us to toggle the BIAS on USB suspend/resume events. This specific handling is only activated when CONFIG_ARCH_AT91SAM9RL is set and this option is only set when building a non-DT kernel, which is problematic since non-DT support for at91sam9rl SoC has been removed. Rework the toggle_bias implementation to attach it to the "at91sam9rl-udc" compatible string. Add new compatible strings to avoid executing at91sam9rl erratum handling on other SoCs.

2014-11-25Merge tag 'usb-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-nextGreg Kroah-Hartman3-2/+49
Felipe writes: usb: patches for v3.19 merge window This time, a very pull request with 216 non-merge commits. Most of the commits contained here are sparse or coccinelle fixes ranging from missing 'static' to returning 0 in case of errors. More importantly, we have the removal the now unnecessary 'driver' argument to ->udc_stop(). DWC2 learned about Dual-Role builds. 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). Other than these, the usual set of cleanups and non-critical fixes. Signed-off-by: Felipe Balbi <balbi@ti.com>

HIRD threshold should be configurable by different platforms. From DesignWare databook: When HIRD_Threshold[4] is set to 1b1 and HIRD value is greater than or equal to the value in HIRD_Threshold[3:0], dwc3 asserts output signals utmi_l1_suspend_n to put PHY into Deep Low-Power mode in L1. When HIRD_Threshold[4] is set to 1b0 or the HIRD value is less than HIRD_Threshold[3:0], dwc3 asserts output signals utmi_sleep_n on L1.

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).

2014-08-27usb: phy: mxs: Add VF610 USB PHY supportStefan Agner1-0/+1
This adds support for the USB PHY in Vybrid VF610. 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.

2014-07-09USB: tegra: Add resets & has-utmi-pad-registers flag to the PHY bindingTuomas Tynkkynen1-0/+8
When Tegra was converted to use the standard reset bindings, the PHY was forgotten, probably because all the resetting of the USB blocks were done in the EHCI driver. What also went unnoticed is that resetting the 1st on-chip USB module also wipes some of the UTMI pad configuration registers that are also used by the other USB blocks. So this fact needs to be described in the device tree, and the driver modified not to reset the 1st module at inappropriate times. In order to stay compatible with old device trees, the USB drivers will still function without these properties but with the old, potentially buggy behaviour.
