| * xhci: Allow xHCI drivers to be built as separate modulesAndrew Bresticker2014-10-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Instead of building all of the xHCI code into a single module, separate it out into the core (xhci-hcd), PCI (xhci-pci, now selected by the new config option CONFIG_USB_XHCI_PCI), and platform (xhci-plat) drivers. Also update the PCI/platform drivers with module descriptions/licenses and have them register their respective drivers in their initcalls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newly added sti ehci and ohci drivers come with a single Kconfig entry that does not depend on either of the base drivers, which leads to a link error when they are disabled: drivers/built-in.o: In function `ohci_platform_init': :(.init.text+0x14788): undefined reference to `ohci_init_driver' To fix that, this patch introduces two separate Kconfig options with proper dependencies, which avoids the problem and is also more consistent with the other glue drivers.

| | | | | | | | | | | | | | | | The dependency on the isp1301 driver is not something that should be in the main OHCI driver but rather the SoC specific part of it. This moves the dependency for LPC32xx into USB_OHCI_HCD_LPC32XX, and changes the 'select ISP1301_OMAP' to a similar 'depends on'. Since the same dependency exists for the client driver, do the same change there.

* usb: ohci-da8xx can only be built-inArnd Bergmann2014-05-271-0/+10
| | | | | | | | | | | | | | | | | | The PHY setup code of the TI DaVinci DA8xx OHCI controller uses ad-hoc register access using a pointer that is meant to be used only by the DaVinci platform implementation and that is intentionally not exported to loadable modules. This results in a link error on configurations that use a modular OHCI code on this platform. While the proper solution for this problem would be to implement a real PHY driver shared by ohci-da8xx and musb-da8xx, this patch for now just works around the build error by only allowing the ohci-da8xx code to be built-in.

| | | | | | | | | | | | | | | | | | | | | Commit a27345434134 "usb: phy: msm: Use reset framework for LINK and PHY resets" introduced a mandatory call to reset_control_get into the msm usb phy driver, which means we have to add a Kconfig dependency on the API to avoid this build error: phy/phy-msm-usb.c: In function 'msm_otg_read_dt': phy/phy-msm-usb.c:1461:2: error: implicit declaration of function 'devm_reset_control_get' [-Werror=implicit-function-declaration] motg->link_rst = devm_reset_control_get(&pdev->dev, "link"); ^ Since the usb-ehci-msm driver currently selects the OTG driver, we could still get a broken dependency here.

* | ehci-platform: Change compatible string from usb-ehci to generic-ehciHans de Goede2014-02-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial versions of the devicetree enablement patches for ehci-platform used "ehci-platform" as compatible string. However this was disliked by various reviewers because the platform bus is a Linux invention and devicetree is supposed to be OS agnostic. After much discussion I gave up, added a: "depends on !PPC_OF" to Kconfig to avoid a known conflict with PPC-OF platforms and went with the generic usb-ehci as requested. In retro-spect I should have chosen something different, the dts files for many existing boards already claim to be compatible with "usb-ehci", ie they have: compatible = "ti,ehci-omap", "usb-ehci"; In theory this should not be a problem since the "ti,ehci-omap" entry takes presedence, but in practice using a conflicting compatible string is an issue, because it makes which driver gets used depend on driver registration order. This patch changes the compatible string claimed by ehci-platform to "generic-ehci", avoiding the driver registration / module loading ordering problems, and removes the "depends on !PPC_OF" workaround.

* | ehci-platform: Add support for clks and phy passed through devicetreeHans de Goede2014-02-071-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ehci-platform is only used in combination with devicetree when used with some Via socs. By extending it to (optionally) get clks and a phy from devicetree, and enabling / disabling those on power_on / off, it can be used more generically. Specifically after this commit it can be used for the ehci controller on Allwinner sunxi SoCs. Since ehci-platform is intended to handle any generic enough non pci ehci device, add a "usb-ehci" compatibility string. There already is a usb-ehci device-tree bindings document, update this with clks and phy bindings info. Although actually quite generic so far the via,vt8500 compatibilty string had its own bindings document. Somehow we even ended up with 2 of them. Since these provide no extra information over the generic usb-ehci documentation, this patch removes them. The ehci-ppc-of.c driver also claims the usb-ehci compatibility string, even though it mostly is ibm,usb-ehci-440epx specific. ehci-platform.c is not needed on ppc platforms, so add a !PPC_OF dependency to it to avoid 2 drivers claiming the same compatibility string getting build on ppc.

Hi Greg, This pull request includes one new feature for the xhci-plat driver (device tree support). Felipe was fine with the patch last I checked, but hadn't provided an official Acked-by line. This pull request also includes 13 patches from my FOSS Outreach Program for Women (OPW) intern, Xenia. She fixed a bug in the xHCI driver so that the driver can allocate 64-bit consistent DMA, converted the driver to use dynamic debugging, and added a bunch of new trace events for the xHCI driver. The python plugin for trace-cmd should be up on git hub shortly, although the trace events are usable without it. I'm very happy with the progress that Xenia has made, and I look forward to her future contributions to the Linux kernel. Sarah Sharp
| * xhci: remove CONFIG_USB_XHCI_HCD_DEBUGGING and unused codeXenia Ragiadakou2013-08-131-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_USB_XHCI_HCD_DEBUGGING option is used to enable verbose debugging output for the xHCI host controller driver. In the current version of the xhci-hcd driver, this option must be turned on, in order for the debugging log messages to be displayed, and users may need to recompile the linux kernel to obtain debugging information that will help them track down problems. This patch removes the above debug option to enable debugging log messages at all times. The aim of this is to rely on the debugfs and the dynamic debugging feature for fine-grained management of debugging messages and to not force users to set the debug config option and compile the linux kernel in order to have access in that information. This patch, also, removes the XHCI_DEBUG symbol and the functions dma_to_stream_ring(), xhci_test_radix_tree() and xhci_event_ring_work() that are not useful anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 9841f37a1c ("usb: ehci: Add support for SINGLE_STEP_SET_FEATURE test of EHSET") added additional code to the EHCI hub driver but it is anticipated to only have a limited audience (e.g. embedded silicon vendors and integrators). Avoid subjecting all EHCI (and in the future maybe xHCI/OHCI, etc.) HCD users to code bloat by conditionally compiling the EHSET-specific additions with a new Kconfig option, CONFIG_USB_HCD_TEST_MODE.

The biggest things in this tag are: DWC3 learned proper usage of threaded IRQ handlers and now we spend very little time in hardirq context. MUSB now has proper support for BeagleBone and Beaglebone Black. Tegra's USB support also got quite a bit of love and is learning to use PHY layer and generic DT attributes.

USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_USB_SUPPORT is not selected we get things like: scripts/kconfig/mconf Kconfig warning: (MIPS_SEAD3 && PMC_MSP && CPU_CAVIUM_OCTEON) selects USB_EHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB) It is much cleaner to make the various system Kconfigs select USB_EHCI_BIG_ENDIAN_MMIO rather than move the system config information into USB's Kconfig, but the warnings are annoying. Eliminate the warning by moving the definition of USB_EHCI_BIG_ENDIAN_MMIO outside of all the Kconfig if statements. While we are at it move USB_OHCI_BIG_ENDIAN_DESC, USB_OHCI_BIG_ENDIAN_MMIO, USB_OHCI_LITTLE_ENDIAN and USB_EHCI_BIG_ENDIAN_DESC too, as they could very well suffer similar problems for other systems.

Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

* | usb: host: make USB_ARCH_HAS_?HCI obsoleteArnd Bergmann2013-06-061-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The three options USB_ARCH_HAS_{EHCI,OHCI,XHCI} are all well beyond their recommended shelf life. They have caused numerous build failures over the years because they are never completely correct, and with the move to splitting out the platform specific back-ends out of the driver, there is no real need for them any more. Also, the use of making USB_ARCH_HAS_HCD depend on it is questionable since one can always enable dummy_hc these days. This patch enables them unconditionally for all platforms and architectures, which means it is now possible to build host controller drivers for machines that are known not to come with this hardware, but that is just how we treat most other drivers. In order to minimise the impact on existing architecture code and defconfig files, all the Kconfig are left present for now. All platforms that currently do 'select USB_ARCH_HAS_*' should subsequently be changed not to select that. All drivers depending on USB_ARCH_HAS_HCD should be changed to depend on USB_SUPPORT instead.
