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. + +Signed-off-by: Hans de Goede <hdegoede@redhat.com> +Acked-by: Alan Stern <stern@rowland.harvard.edu> +--- + Documentation/devicetree/bindings/usb/usb-ehci.txt | 25 +++- + .../devicetree/bindings/usb/via,vt8500-ehci.txt | 15 --- + .../devicetree/bindings/usb/vt8500-ehci.txt | 12 -- + drivers/usb/host/Kconfig | 1 + + drivers/usb/host/ehci-platform.c | 147 +++++++++++++++++---- + 5 files changed, 142 insertions(+), 58 deletions(-) + delete mode 100644 Documentation/devicetree/bindings/usb/via,vt8500-ehci.txt + delete mode 100644 Documentation/devicetree/bindings/usb/vt8500-ehci.txt + +diff --git a/Documentation/devicetree/bindings/usb/usb-ehci.txt b/Documentation/devicetree/bindings/usb/usb-ehci.txt +index fa18612..2c1aeeb 100644 +--- a/Documentation/devicetree/bindings/usb/usb-ehci.txt ++++ b/Documentation/devicetree/bindings/usb/usb-ehci.txt +@@ -7,13 +7,14 @@ Required properties: + (debug-port or other) can be also specified here, but only after + definition of standard EHCI registers. + - interrupts : one EHCI interrupt should be described here. +-If device registers are implemented in big endian mode, the device +-node should have "big-endian-regs" property. +-If controller implementation operates with big endian descriptors, +-"big-endian-desc" property should be specified. +-If both big endian registers and descriptors are used by the controller +-implementation, "big-endian" property can be specified instead of having +-both "big-endian-regs" and "big-endian-desc". ++ ++Optional properties: ++ - big-endian-regs : boolean, set this for hcds with big-endian registers ++ - big-endian-desc : boolean, set this for hcds with big-endian descriptors ++ - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc ++ - clocks : a list of phandle + clock specifier pairs ++ - phys : phandle + phy specifier pair ++ - phy-names : "usb" + + Example (Sequoia 440EPx): + ehci@e0000300 { +@@ -23,3 +24,13 @@ Example (Sequoia 440EPx): + reg = <0 e0000300 90 0 e0000390 70>; + big-endian; + }; ++ ++Example (Allwinner sun4i A10 SoC): ++ ehci0: usb@01c14000 { ++ compatible = "allwinner,sun4i-a10-ehci", "usb-ehci"; ++ reg = <0x01c14000 0x100>; ++ interrupts = <39>; ++ clocks = <&ahb_gates 1>; ++ phys = <&usbphy 1>; ++ phy-names = "usb"; ++ }; +diff --git a/Documentation/devicetree/bindings/usb/via,vt8500-ehci.txt b/Documentation/devicetree/bindings/usb/via,vt8500-ehci.txt +deleted file mode 100644 +index 17b3ad1..0000000 +--- a/Documentation/devicetree/bindings/usb/via,vt8500-ehci.txt ++++ /dev/null +@@ -1,15 +0,0 @@ +-VIA/Wondermedia VT8500 EHCI Controller +------------------------------------------------------ +- +-Required properties: +-- compatible : "via,vt8500-ehci" +-- reg : Should contain 1 register ranges(address and length) +-- interrupts : ehci controller interrupt +- +-Example: +- +- ehci@d8007900 { +- compatible = "via,vt8500-ehci"; +- reg = <0xd8007900 0x200>; +- interrupts = <43>; +- }; +diff --git a/Documentation/devicetree/bindings/usb/vt8500-ehci.txt b/Documentation/devicetree/bindings/usb/vt8500-ehci.txt +deleted file mode 100644 +index 5fb8fd6..0000000 +--- a/Documentation/devicetree/bindings/usb/vt8500-ehci.txt ++++ /dev/null +@@ -1,12 +0,0 @@ +-VIA VT8500 and Wondermedia WM8xxx SoC USB controllers. +- +-Required properties: +- - compatible: Should be "via,vt8500-ehci" or "wm,prizm-ehci". +- - reg: Address range of the ehci registers. size should be 0x200 +- - interrupts: Should contain the ehci interrupt. +- +-usb: ehci@D8007100 { +- compatible = "wm,prizm-ehci", "usb-ehci"; +- reg = <0xD8007100 0x200>; +- interrupts = <1>; +-}; +diff --git a/drivers/usb/host/Kconfig b/drivers/usb/host/Kconfig +index a9707da..e28cbe0 100644 +--- a/drivers/usb/host/Kconfig ++++ b/drivers/usb/host/Kconfig +@@ -255,6 +255,7 @@ config USB_EHCI_ATH79 + + config USB_EHCI_HCD_PLATFORM + tristate "Generic EHCI driver for a platform device" ++ depends on !PPC_OF + default n + ---help--- + Adds an EHCI host driver for a generic platform device, which +diff --git a/drivers/usb/host/ehci-platform.c b/drivers/usb/host/ehci-platform.c +index 01536cf..5ebd0b7 100644 +--- a/drivers/usb/host/ehci-platform.c ++++ b/drivers/usb/host/ehci-platform.c +@@ -3,6 +3,7 @@ + * + * Copyright 2007 Steven Brown <sbrown@cortland.com> + * Copyright 2010-2012 Hauke Mehrtens <hauke@hauke-m.de> ++ * Copyright 2014 Hans de Goede <hdegoede@redhat.com> + * + * Derived from the ohci-ssb driver + * Copyright 2007 Michael Buesch <m@bues.ch> +@@ -18,6 +19,7 @@ + * + * Licensed under the GNU/GPL.

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. + +Signed-off-by: Hans de Goede <hdegoede@redhat.com> +--- + Documentation/devicetree/bindings/usb/usb-ehci.txt | 4 ++-- + drivers/usb/host/Kconfig | 1 - + drivers/usb/host/ehci-platform.c | 2 +- + 3 files changed, 3 insertions(+), 4 deletions(-) + +diff --git a/Documentation/devicetree/bindings/usb/usb-ehci.txt b/Documentation/devicetree/bindings/usb/usb-ehci.txt +index 2c1aeeb..ff151ec 100644 +--- a/Documentation/devicetree/bindings/usb/usb-ehci.txt ++++ b/Documentation/devicetree/bindings/usb/usb-ehci.txt +@@ -1,7 +1,7 @@ + USB EHCI controllers + + Required properties: +- - compatible : should be "usb-ehci". ++ - compatible : should be "generic-ehci". + - reg : should contain at least address and length of the standard EHCI + register set for the device.
