From f2516e53c1678faa9a23d27aadf2c2d8c3370a51 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 7 Mar 2017 09:50:42 +0100 Subject: [PATCH] kernel: fix usb chipidea controller support If ehci platform driver is loaded before the chipidea controller driver, both are competing for the same IO resources and the generic driver gets used for the hardware. This results in USB device mode being unavailable. Split generic EHCI support code out of kmod-usb2, so that the chipidea driver can be included without also pulling in the generic one. Also rework the load order, so that the chipidea driver gets loaded first, in case both are installed Signed-off-by: Felix Fietkau --- package/kernel/linux/modules/usb.mk | 27 +++++++++++++++++++-------- 1 file changed, 19 insertions(+), 8 deletions(-) diff --git a/package/kernel/linux/modules/usb.mk b/package/kernel/linux/modules/usb.mk index 304afeca78..d384e3076a 100644 --- a/package/kernel/linux/modules/usb.mk +++ b/package/kernel/linux/modules/usb.mk @@ -60,7 +60,7 @@ define KernelPackage/usb-phy-nop KCONFIG:=CONFIG_NOP_USB_XCEIV HIDDEN:=1 FILES:=$(LINUX_DIR)/drivers/usb/phy/phy-generic.ko - AUTOLOAD:=$(call AutoLoad,43,phy-generic) + AUTOLOAD:=$(call AutoLoad,21,phy-generic,1) $(call AddDepends/usb) endef @@ -77,7 +77,7 @@ define KernelPackage/usb-gadget HIDDEN:=1 FILES:=\ $(LINUX_DIR)/drivers/usb/gadget/udc/udc-core.ko - AUTOLOAD:=$(call AutoLoad,45,udc-core) + AUTOLOAD:=$(call AutoLoad,21,udc-core,1) DEPENDS:=@USB_GADGET_SUPPORT $(call AddDepends/usb) endef @@ -273,25 +273,36 @@ define KernelPackage/usb-ssb endef $(eval $(call KernelPackage,usb-ssb)) +define KernelPackage/usb-ehci + TITLE:=EHCI controller support + HIDDEN:=1 + KCONFIG:= \ + CONFIG_USB_EHCI_HCD + FILES:= \ + $(LINUX_DIR)/drivers/usb/host/ehci-hcd.ko + AUTOLOAD:=$(call AutoLoad,35,ehci-hcd,1) + $(call AddDepends/usb) +endef +$(eval $(call KernelPackage,usb-ehci)) + define KernelPackage/usb2 TITLE:=Support for USB2 controllers DEPENDS:=\ +TARGET_brcm47xx:kmod-usb-bcma \ +TARGET_brcm47xx:kmod-usb-ssb \ +TARGET_bcm53xx:kmod-usb-bcma \ - +TARGET_bcm53xx:kmod-phy-bcm-ns-usb2 + +TARGET_bcm53xx:kmod-phy-bcm-ns-usb2 \ + +kmod-usb-ehci KCONFIG:=\ - CONFIG_USB_EHCI_HCD \ + CONFIG_USB_EHCI_HCD_PLATFORM \ CONFIG_USB_EHCI_BCM63XX=y \ CONFIG_USB_IMX21_HCD=y \ CONFIG_USB_EHCI_MXC=y \ CONFIG_USB_OCTEON_EHCI=y \ CONFIG_USB_EHCI_HCD_ORION=y \ - CONFIG_USB_EHCI_HCD_PLATFORM=y \ CONFIG_USB_EHCI_HCD_AT91=y \ CONFIG_USB_EHCI_FSL FILES:= \ - $(LINUX_DIR)/drivers/usb/host/ehci-hcd.ko \ $(LINUX_DIR)/drivers/usb/host/ehci-platform.ko ifneq ($(wildcard $(LINUX_DIR)/drivers/usb/host/ehci-orion.ko),) FILES+=$(LINUX_DIR)/drivers/usb/host/ehci-orion.ko @@ -1376,7 +1387,7 @@ $(eval $(call KernelPackage,usbip-server)) define KernelPackage/usb-chipidea TITLE:=Host and device support for Chipidea controllers - DEPENDS:=+USB_GADGET_SUPPORT:kmod-usb-gadget @TARGET_ar71xx +kmod-usb2 + DEPENDS:=+USB_GADGET_SUPPORT:kmod-usb-gadget @TARGET_ar71xx +kmod-usb-ehci KCONFIG:= \ CONFIG_NOP_USB_XCEIV=y \ CONFIG_EXTCON \ @@ -1388,7 +1399,7 @@ define KernelPackage/usb-chipidea $(LINUX_DIR)/drivers/extcon/extcon.ko@lt4.9 \ $(LINUX_DIR)/drivers/extcon/extcon-core.ko@ge4.9 \ $(LINUX_DIR)/drivers/usb/chipidea/ci_hdrc.ko - AUTOLOAD:=$(call AutoLoad,51,ci_hdrc,0) + AUTOLOAD:=$(call AutoLoad,39,ci_hdrc,1) $(call AddDepends/usb) endef -- 2.30.2
