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.

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.

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.

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.

This removes knowledge of internal FDT details from most architectures except powerpc. - Conversion of kernel's custom FDT parsing code to use libfdt. - DT based initialization for generic serial earlycon. The introduction of generic serial earlycon support went in through the tty tree. - Improve the platform device naming for DT probed devices to ensure unique naming and use parent names instead of a global index. - Fix a race condition in of_update_property. - Unify the various linker section OF match tables and fix several function prototype errors. - Update platform_get_irq_byname to work in deferred probe cases. - 2 binding doc updates * tag 'devicetree-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (58 commits) of: handle NULL node in next_child iterators of/irq: provide more wrappers for !CONFIG_OF devicetree: bindings: Document micrel vendor prefix dt: bindings: dwc2: fix required value for the phy-names property of_pci_irq: kill useless variable in of_irq_parse_pci() of/irq: do irq resolution in platform_get_irq_byname() of: Add a testcase for of_find_node_by_path() of: Make of_find_node_by_path() handle /aliases of: Create unlocked version of for_each_child_of_node() lib: add glibc style strchrnul() variant of: Handle memory@0 node on PPC32 only pci/of: Remove dead code of: fix race between search and remove in of_update_property() of: Use NULL for pointers of: Stop naming platform_device using dcr address of: Ensure unique names without sacrificing determinism tty/serial: pl011: add DT based earlycon support of/fdt: add FDT serial scanning for earlycon of/fdt: add FDT address translation support serial: earlycon: add DT support ...
2014-06-03Merge tag 'usb-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb into nextLinus Torvalds9-8/+161
Pull USB driver updates from Greg KH: "Here is the big USB driver pull request for 3.16-rc1. Nothing huge here, but lots of little things in the USB core, and in lots of drivers. Hopefully the USB power management will be work better now that it has been reworked to do per-port power control dynamically. There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG is finally gone now that everything has been converted over to the dynamic debug inteface, the last hold-out drivers were cleaned up and the config option removed. There were also other minor things all through the drivers/usb/ tree, the shortlog shows this pretty well. All have been in linux-next, including the very last patch, which came from linux-next to fix a build issue on some platforms" * tag 'usb-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (314 commits) usb: hub_handle_remote_wakeup() only exists for CONFIG_PM=y USB: orinoco_usb: remove CONFIG_USB_DEBUG support USB: media: lirc: igorplugusb: remove CONFIG_USB_DEBUG support USB: media: streamzap: remove CONFIG_USB_DEBUG USB: media: redrat3: remove CONFIG_USB_DEBUG usage USB: media: redrat3: remove unneeded tracing macro usb: qcserial: add additional Sierra Wireless QMI devices usb: host: max3421-hcd: Use module_spi_driver usb: host: max3421-hcd: Allow platform-data to specify Vbus polarity usb: host: max3421-hcd: fix "spi_rd8" uses dynamic stack allocation warning usb: host: max3421-hcd: Fix missing unlock in max3421_urb_enqueue() usb: qcserial: add Netgear AirCard 341U Documentation: dt-bindings: update xhci-platform DT binding for R-Car H2 and M2 usb: host: xhci-plat: add xhci_plat_start() usb: host: max3421-hcd: Fix potential NULL urb dereference Revert "usb: gadget: net2280: Add support for PLX USB338X" USB: usbip: remove CONFIG_USB_DEBUG reference USB: remove CONFIG_USB_DEBUG from defconfig files usb: resume child device when port is powered on usb: hub_handle_remote_wakeup() depends on CONFIG_PM_RUNTIME=y ...
2014-05-28Documentation: dt-bindings: update xhci-platform DT binding for R-Car H2 and M2Yoshihiro Shimoda1-1/+2
This commit extends the compatible string list of the xhci-platform binding with the new "renesas,xhci-r8a7790" and "renesas,xhci-r8a7791" compatible strings. It is used to describe the xHCI controller which is available in the R-Car H2 and M2 SoCs.
