From mboxrd@z Thu Jan 1 00:00:00 1970 From: chao.xie@marvell.com (Chao Xie) Date: Wed, 20 Feb 2013 23:07:10 -0500 Subject: [V8 PATCH 00/16] mv-usb phy enhancement patches Message-ID: <1361419646-9052-1-git-send-email-chao.xie@marvell.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The patches are divied into 2 parts 1. PHY driver To remove the callbacks in the platform data, a usb PHY driver for marvell udc/otg/ehci is written. For device tree support, it is not good to pass the callback pointers by platform data. The PHY driver also removes the block. usb: phy: mv_usb2: add PHY driver for marvell usb2 controller usb: gadget: mv_udc: use PHY driver for udc usb: ehci: ehci-mv: use PHY driver for ehci usb: otg: mv_otg: use PHY driver for otg Above patches are marvell usb PHY driver support. arm: mmp2: change the defintion of usb devices arm: pxa910: change the defintion of usb devices arm: brownstone: add usb support for the board arm: ttc_dkb: add usb support arm: mmp: remove the usb phy setting arm: mmp: remove usb devices from pxa168 Above patches are for SOC/board support for marvell usb PHY driver. 2. external chip support The marvell usb controller can detect the vbus/idpin, but it need PHY and usb clocks to be enabled. Based on measurement it will import 15mA current, and increase the power when the usb is not used. Using a external chip to detect vbus/idpin changes will save the power. In fact the marvell PMIC 88pm860x and 88pm80x can do it. The drivers are located at drivers/mfd. So add a middle layer in the marvell usb PHY driver. PMIC call the APIs in middle driver to registers the callback for vbus/idpin detection/query udc/otg/ehci driver will call the APIs to get vbus/idpin changes and query the states of the vbus/idpin. usb: phy: mv_usb2_phy: add externel chip support usb: gadget: mv_udc: add extern chip support usb: ehci: ehci-mv: add extern chip support usb: otg: mv_otg: add extern chip support Above patches are the middle layer suppor for udc/otg/ehci arm: mmp: add extern chip support for brownstone arm: mmp: add extern chip support for ttc_dkb Above patches are corresponding board file changes V2->V1: Change the Signed-off-by to be right email address v3->v2 re-format the patches to new code base v4->v3 1. make mv udc gadget driver depend on ARCH_PXA and ARCH_MMP 2. remove __devinit and __devexit 3. make the driver compiled successful if CONFIG_MV_USB2_PHY is not defined. The modified patches are usb: gadget: mv_udc: make mv_udc depends on ARCH_MMP or ARCH_PXA usb: phy: mv_usb2: add PHY driver for marvell usb2 controller v5->v4 make the struct mv_usb2_extern_chip member ->head to be struct atomic_notifier_head instead of struct atomic_notifier_head *. v6->v5 the bug fix patches are merged. Removed the dependcy of ARCH_MMP and ARCH_PXA, and make the driver can be compiled for x86. The device tree support patches need modification, remove them from this patch series, and they will be submitted in another series. v7->v6 Use usb_add_phy_dev and related APIs to add PHY drivers. Removed the device tree support in PHY driver. It will be added in another patch series. v8->v7 bugs fix in phy driver. directly use devm_usb_get_phy_dev return value for error return. Chao Xie (16): usb: phy: mv_usb2: add PHY driver for marvell usb2 controller usb: gadget: mv_udc: use PHY driver for udc usb: ehci: ehci-mv: use PHY driver for ehci usb: otg: mv_otg: use PHY driver for otg arm: mmp2: change the defintion of usb devices arm: pxa910: change the defintion of usb devices arm: brownstone: add usb support for the board arm: ttc_dkb: add usb support arm: mmp: remove the usb phy setting arm: mmp: remove usb devices from pxa168 usb: phy: mv_usb2_phy: add externel chip support usb: gadget: mv_udc: add extern chip support usb: ehci: ehci-mv: add extern chip support usb: otg: mv_otg: add extern chip support arm: mmp: add extern chip support for brownstone arm: mmp: add extern chip support for ttc_dkb arch/arm/mach-mmp/brownstone.c | 66 +++++ arch/arm/mach-mmp/devices.c | 278 ------------------ arch/arm/mach-mmp/include/mach/mmp2.h | 4 + arch/arm/mach-mmp/include/mach/pxa910.h | 7 +- arch/arm/mach-mmp/include/mach/regs-usb.h | 253 ---------------- arch/arm/mach-mmp/mmp2.c | 4 + arch/arm/mach-mmp/pxa168.c | 42 --- arch/arm/mach-mmp/pxa910.c | 4 + arch/arm/mach-mmp/ttc_dkb.c | 52 +++- drivers/usb/gadget/mv_udc.h | 5 +- drivers/usb/gadget/mv_udc_core.c | 101 ++++--- drivers/usb/host/ehci-mv.c | 64 ++--- drivers/usb/otg/mv_otg.c | 122 ++++---- drivers/usb/otg/mv_otg.h | 5 +- drivers/usb/phy/Kconfig | 7 + drivers/usb/phy/Makefile | 1 + drivers/usb/phy/mv_usb2_phy.c | 451 +++++++++++++++++++++++++++++ include/linux/platform_data/mv_usb.h | 22 +- include/linux/usb/mv_usb2.h | 121 ++++++++ 19 files changed, 856 insertions(+), 753 deletions(-) delete mode 100644 arch/arm/mach-mmp/include/mach/regs-usb.h create mode 100644 drivers/usb/phy/mv_usb2_phy.c create mode 100644 include/linux/usb/mv_usb2.h -- 1.7.4.1
