* usb: phy: msm: fix error handling in probe.Srinivas Kandagatla2016-02-031-13/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver registers for extcon events as part of its probe, but never unregisters them in case of error in the probe path. There were multiple issues noticed due to this missing error handling. One of them is random crashes if the regulators are not ready yet by the time probe is invoked. Ivan's previous attempt [1] to fix this issue, did not really address all the failure cases like regualtor/get_irq failures. [1] https://lkml.org/lkml/2015/9/7/62 Without this patch the kernel would carsh with log: ...

* usb: musb: core: Fix handling of the phy notificationsTony Lindgren2015-12-161-15/+15
| | | | | | | | | | | | | | | | | | | | | We currently can't unload omap2430 MUSB platform glue driver module and this cause issues for fixing the MUSB code further. The reason we can't remove omap2430 is because it uses the PHY functions and also exports the omap_musb_mailbox function that some PHY drivers are using. Let's fix the issue by exporting a more generic musb_mailbox function from the MUSB core and allow platform glue layers to register phy_callback function as needed. And now we can now also get rid of the include/linux/musb-omap.h.

* usb: phy: phy-am335x: bypass first VBUS sensing for host-only modeBin Liu2015-12-164-11/+27
| | | | | | | | | | | | | | To prevent VBUS contention, the am335x MUSB phy senses VBUS first before transitioning to host mode. However, for host-only mode, VBUS could be directly tied to 5V power rail which could prevent MUSB transitions to host mode. This change receives dr_mode of the controller then bypass the first VBUS sensing for host-only mode, so that MUSB can work in host mode event if VBUS is tied to 5V.

* usb: phy: Remove unused Renesas R-Car (Gen1) USB PHY driverGeert Uytterhoeven2015-12-153-261/+0
| | | | | | | | | | | | | | | As of commit 3d7608e4c169af03 ("ARM: shmobile: bockw: remove legacy board file and config"), the Renesas R-Car (Gen1) USB PHY driver is no longer used. In theory it could still be used on R-Car Gen1 SoCs, but that would require adding DT support to the driver. Instead, a new driver using the generic PHY framework should be written, as was done for R-Car Gen2. Remove the driver for good.

This is useful when a battery-charger is intimately associated with a particular phy but handled by a separate driver. The charger can find the device_node based on sibling relationships without the need for a redundant declaration in the devicetree description. As a peripheral that gets a phy will often want to register a notifier block, and de-register it later, that functionality is included so the de-registration is automatic.

So, I have the plan to move this definitions to following header file which includes the unique id of supported external connectors. - include/dt-bindings/extcon/extcon.h Fixes: 2a9de9c0f08d ("extcon: Use the unique id for external connector instead of string") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The string name have the many potential issues. So, this patch defines the 'extcon' enumeration which includes all supported external connector on EXTCON subsystem. If new external connector is necessary, the unique id of new connector have to be added in 'extcon' enumeration. There are current supported external connector in 'enum extcon' as following: enum extcon { EXTCON_NONE = 0x0, /* USB external connector */ EXTCON_USB = 0x1, EXTCON_USB_HOST = 0x2, /* Charger external connector */ EXTCON_TA = 0x10, EXTCON_FAST_CHARGER = 0x11, EXTCON_SLOW_CHARGER = 0x12, EXTCON_CHARGE_DOWNSTREAM = 0x13, /* Audio and video external connector */ EXTCON_LINE_IN = 0x20, EXTCON_LINE_OUT = 0x21, EXTCON_MICROPHONE = 0x22, EXTCON_HEADPHONE = 0x23, EXTCON_HDMI = 0x30, EXTCON_MHL = 0x31, EXTCON_DVI = 0x32, EXTCON_VGA = 0x33, EXTCON_SPDIF_IN = 0x34, EXTCON_SPDIF_OUT = 0x35, EXTCON_VIDEO_IN = 0x36, EXTCON_VIDEO_OUT = 0x37, /* Miscellaneous external connector */ EXTCON_DOCK = 0x50, EXTCON_JIG = 0x51, EXTCON_MECHANICAL = 0x52, EXTCON_END, }; For example in extcon-arizona.c: To use unique id removes the potential issue about handling the inconsistent name of external connector with string. - Previously, use the string to register the type of arizona jack connector static const char *arizona_cable[] = { "Mechanical", "Microphone", "Headphone", "Line-out", }; - Newly, use the unique id to register the type of arizona jack connector static const enum extcon arizona_cable[] = { EXTCON_MECHANICAL, EXTCON_MICROPHONE, EXTCON_HEADPHONE, EXTCON_LINE_OUT, EXTCON_NONE, }; And this patch modify the prototype of extcon_{get|set}_cable_state_() which uses the 'enum extcon id' instead of 'cable_index'. Because although one more extcon drivers support USB cable, each extcon driver might has the differnt 'cable_index' for USB cable. All extcon drivers can use the unique id number for same external connector with modified extcon_{get|set}_cable_state_(). - Previously, use 'cable_index' on these functions: extcon_get_cable_state_(struct extcon_dev*, int cable_index) extcon_set_cable_state_(struct extcon_dev*, int cable_index, bool state) -Newly, use 'enum extcon id' on these functions: extcon_get_cable_state_(struct extcon_dev*, enum extcon id) extcon_set_cable_state_(struct extcon_dev*, enum extcon id, bool state) Cc: Arnd Bergmann <arnd@arndb.de> Cc: Felipe Balbi <balbi@ti.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Roger Quadros <rogerq@ti.com> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> [arnd: Report the build break about drivers/usb/phy/phy-tahvo.c after using the unique id for external connector insteadf of string] Reported-by: Arnd Bergmann <arnd@arndb.de> [dan.carpenter: Report the build warning of extcon_{set|get}_cable_state_()] Reported-by: Dan Carpenter <dan.carpenter@oracle.com>

|/ | | | | | | | | | | | | | | | | | | | The isp1301-omap driver contains special hooks for the TPS65010 power management controller. It provides its own 'tps65010_set_vbus_draw' wrapper in case that driver is not enabled through Kconfig, but fails to handle the case where isp1301-omap is built-in but TPS65010 is a loadable module, which currently results in a link error: drivers/built-in.o: In function `isp1301_set_power': :(.text+0x14e188): undefined reference to `tps65010_set_vbus_draw' This is a workaround to use the same trick as before also when tps65010 is a module. Doing a proper fix would require much larger changes to the driver that is not really worth it when the usb-phy drivers are going to eventually get replaced with generic-phy drivers.

Also, in usb_gen_phy_shutdown() we can simply put the GPIO directly in its active level state and this allows us to simplify the nop_reset function to treat only the reset case.
