extcon: palmas: Fix boot up state of VBUS when using GPIO detection

2016-06-15T08:17:22Z

If USB cable is connected prior to boot, we don't get any interrupts so we must manually check the VBUS state and report it during probe. If we don't do it then USB controller will never know that peripheral cable was connected till the user unplugs and replugs the cable.

extcon: palmas: Drop stray IRQF_EARLY_RESUME flag

2016-04-03T23:32:45Z

Palmas extcon IRQs are nested threaded and wired to the Palmas interrupt controller. So, this flag is not required for nested IRQs anymore, since commit 3c646f2c6aa9 ("genirq: Don't suspend nested_thread irqs over system suspend") was merged. However, the fix in commit ae64e42cc2b3 ("extcon: palmas: Drop IRQF_EARLY_RESUME flag") missed a stray flag causing the following crash on resume on BeagleBoard-X15 platform: [ 53.670141] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [..] [ 53.670141] [] (omap_set_gpio_triggering) from [] (omap_gpio_unmask_irq+0xc0/0xc4) [ 53.670141] [] (omap_gpio_unmask_irq) from [] (irq_enable+0x30/0x44) [ 53.670141] [] (irq_enable) from [] (__enable_irq+0x54/0x78) [ 53.670141] [] (__enable_irq) from [] (resume_irqs+0xe8/0x100) [ 53.670141] [] (resume_irqs) from [] (syscore_resume+0x94/0x298) [ 53.670141] [] (syscore_resume) from [] (suspend_devices_and_enter+0x790/0x9e4) [ 53.670141] [] (suspend_devices_and_enter) from [] (pm_suspend+0x640/0x75c) [ 53.670141] [] (pm_suspend) from [] (state_store+0x64/0xb8) [ 53.670141] [] (state_store) from [] (kernfs_fop_write+0xc0/0x1bc) [ 53.670141] [] (kernfs_fop_write) from [] (__vfs_write+0x1c/0xd8) [ 53.670141] [] (__vfs_write) from [] (vfs_write+0x90/0x16c) [ 53.670141] [] (vfs_write) from [] (SyS_write+0x44/0x9c) [ 53.670141] [] (SyS_write) from [] (ret_fast_syscall+0x0/0x1c) [..] Fixes: ae64e42cc2b3 ("extcon: palmas: Drop IRQF_EARLY_RESUME flag") Cc: Grygorii Strashko Cc: MyungJoo Ham Cc: Chanwoo Choi Cc: Tony Lindgren Cc: Lee Jones Cc: Roger Quadros Reviewed-by: Grygorii Strashko Signed-off-by: Nishanth Menon Acked-by: Roger Quadros Signed-off-by: Chanwoo Choi

extcon: arizona: Use DAPM mutex helper functions

2016-01-25T04:16:53Z

We should be using the helper functions to lock the DAPM mutex not accessing it directly. There are no ill effects of this as the moment but it is best practice, and the implementation could be changed in the future. Signed-off-by: Charles Keepax Signed-off-by: Chanwoo Choi

extcon: Add the EXTCON_CHG_USB_SDP to support SDP charing port

This patch adds the new EXTCON_CHG_USB_SDP connector to support SDP (Standard Downstream Port) USB charging port. The commit 11eecf910bd8 ("extcon: Modify the id and name of external connector") add the new EXTCON_CHG_USB_SDP connector which support the both data transfer and usb charging at the same time.

extcon: add Maxim MAX3355 driver

2015-12-21T02:44:00Z

Maxim Integrated MAX3355E chip integrates a charge pump and comparators to enable a system with an integrated USB OTG dual-role transceiver to function as an USB OTG dual-role device. In addition to sensing/controlling Vbus, the chip also passes thru the ID signal from the USB OTG connector. On some Renesas boards, this signal is just fed into the SoC thru a GPIO pin -- there's no real OTG controller, only host and gadget USB controllers sharing the same USB bus; however, we'd like to allow host or gadget drivers to be loaded depending on the cable type, hence the need for the MAX3355 extcon driver. The Vbus status signals are also wired to GPIOs (however, we aren't currently interested in them), the OFFVBUS# signal is controlled by the host controllers, there's also the SHDN# signal wired to a GPIO, it should be driven high for the normal operation.
