2014-07-10USB: oxu210hp-hcd.c: use devm_ functionsHimangi Saraogi1-39/+9
This patch introduces the use of devm_ioremap_resource instead of request_mem_region and ioremap. The error handling on platform_get_resource and the error message for ioremap are removed. The function devm_kzalloc replaces memory allocation by unmanaged kzalloc. The function calls to free the allocated memory in the probe and remove functions are done away with. Some labels are removed and a label error is added to make is less specific to the context. The debug message is removed as devm_ioremap generates debug messages of its own.

There's no power/persist file for hubs. And CONFIG_USB_PERSIST was removed in v2.6.26. Update the description of power/persist accordingly. Also remove the line on its default value. It is not entirely correct, as CONFIG_USB_DEFAULT_PERSIST and the USB_QUIRK_RESET flag influence the default. It is not needed to understand this file anyhow.

2014-07-10usb: force warm reset to break link re-connect livelockDan Williams3-20/+39
Resuming a powered down port sometimes results in the port state being stuck in the training sequence. hub 3-0:1.0: debounce: port 1: total 2000ms stable 0ms status 0x2e0 port1: can't get reconnection after setting port power on, status -110 hub 3-0:1.0: port 1 status 0000.02e0 after resume, -19 usb 3-1: can't resume, status -19 hub 3-0:1.0: logical disconnect on port 1 In the case above we wait for the port re-connect timeout of 2 seconds and observe that the port status is USB_SS_PORT_LS_POLLING (although it is likely toggling between this state and USB_SS_PORT_LS_RX_DETECT). This is indicative of a case where the device is failing to progress the link training state machine. It is resolved by issuing a warm reset to get the hub and device link state machines back in sync. hub 3-0:1.0: debounce: port 1: total 2000ms stable 0ms status 0x2e0 usb usb3: port1 usb_port_runtime_resume requires warm reset hub 3-0:1.0: port 1 not warm reset yet, waiting 50ms usb 3-1: reset SuperSpeed USB device number 2 using xhci_hcd After a reconnect timeout when we expect the device to be present, force a warm reset of the device. Note that we can not simply look at the link status to determine if a warm reset is required as any of the training states USB_SS_PORT_LS_POLLING, USB_SS_PORT_LS_RX_DETECT, or USB_SS_PORT_LS_COMP_MOD are valid states that do not indicate the need for warm reset by themselves.

2014-07-10usb: allow lpm (en/dis)able only if device is atleast in default statePratyush Anand1-2/+4
When a USB device is disconnected, usb_unbind_interface is called, which tries to enable and disable LPM. usb_enable_lpm also try to send a control command SET SEL to the device. Since device is already disconnected, therefore it does not make sense to execute usb_(en/dis)able_lpm. This patch returns from usb_(en/dis)able_lpm, if device was not in default state atleast.

2014-07-10xhci: A default implementation for Ux timeout calculation and tier policy checkPratyush Anand1-18/+48
As best case, a host controller should support U0 to U1 switching for the devices connected below any tier of hub level supported by usb specification. Therefore xhci_check_tier_policy should always return success as default implementation. A host should be able to issue LGO_Ux after the timeout calculated as per definition of system exit latency defined in C.1.5.2. Therefore xhci_calculate_ux_timeout returns ux_params.sel as the default implementation. Use default calculation in absence of any vendor specific limitations.

2014-07-05ARM: sunxi: Reintroduce the restart code for A10/A20 SoCsMaxime Ripard1-0/+77
This partly reverts commits 553600502b84 (ARM: sunxi: Remove reset code from the platform) and 5e669ec583e2 (ARM: sunxi: Remove init_machine callback) for the sun4i, sun5i and sun7i families. This is needed because the watchdog counterpart of these commits was dropped, and didn't make it into 3.16. In order to still be able to reboot the board, we need to reintroduce that code. Of course, the long term view is still to get rid of that code in mach-sunxi. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Olof Johansson <olof@lixom.net>

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Merge OMAP fixes from Tony Lindgren: Fixes for omaps for issues discovered during the merge window and enabling of a few features that had to wait for the driver dependencies to clear. The fixes included are: - Fix am43xx hard reset flags - Fix SoC detection for DRA722 - Fix CPU OPP table for omap5 - Fix legacy mux parser bug if requested muxname is a prefix of multiple mux entries - Fix qspi interrupt binding that relies on the irq crossbar that has not yet been enabled - Add missing phy_sel for am43x-epos-evm - Drop unused gic_init_irq() that is no longer needed And the enabling of features that had driver dependencies are: - Change dra7 to use Audio Tracking Logic clock instead of a fixed clock now that the clock driver for it has been merged - Enable off idle configuration for selected omaps as all the kernel dependencies for device tree based booting are finally merged as this is needed to get the automated PM tests working finally with device tree based booting - Add hwmod entry for ocp2scp3 for omap5 to get sata working as all the driver dependencies are now in the kernel and this patch fell through the cracks during the merge window * tag 'omap-for-v3.16/fixes-against-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: dra7-evm: remove interrupt binding ARM: OMAP2+: Fix parser-bug in platform muxing code ARM: DTS: dra7/dra7xx-clocks: ATL related changes ARM: OMAP2+: drop unused function ARM: dts: am43x-epos-evm: Add Missing cpsw-phy-sel for am43x-epos-evm ARM: dts: omap5: Update CPU OPP table as per final production Manual ARM: DRA722: add detection of SoC information ARM: dts: Enable twl4030 off-idle configuration for selected omaps ARM: OMAP5: hwmod: Add ocp2scp3 and sata hwmods ARM: OMAP2+: hwmod: Change hardreset soc_ops for AM43XX
