2012-05-15usb: ehci: tegra: Split resume & suspend call appropriatelyPreetham Chandru
tegra_ehci_suspend_noirq/tegra_ehci_resume_noirq breaks the modem suspend call as it does a regulator_disable()/regulator_enable call which in turn requires the irqs to be enabled. Hence maintain a normal suspend call i.e with irqs enabled but split the resume to normal resume and noirq resume. Spliting the resume in this way takes care of the below erros in lp0/lp1 "tegra-ehci tegra-ehci.2:fatal error" "tegra-ehci tegra-ehci.2: HC died; cleaning up" Originally resume_noirq & suspend_noirq were added to avoid the above errors but since it breaks the modem suspend call splitting the suspend and resume in this way Bug 954564 Signed-off-by: Preetham Chandru R <pchandru@nvidia.com> Change-Id: I630b3dbe2ca66d194857dc71ababa3e5955785b1 Reviewed-on: http://git-master/r/99100 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Bitan Biswas <bbiswas@nvidia.com>

The maximum current draw was hard coded to 500 mA. composite.c has code that uses CONFIG_USB_GADGET_VBUS_DRAW to set the bMaxPower and to set whether or not the device is self-powered if they haven't been set. This change removes the code in android.c to allow composite.c to set them.

commit 62aaf24dc125d7c55c93e313d15611f152b030c7 upstream. wdm_disconnect() waits for the mutex held by wdm_read() before calling wake_up_all(). This causes a deadlock, preventing device removal to complete. Do the wake_up_all() before we start waiting for the locks.
