2012-08-10arm: tegra: xmm: device set to null in unregisterVinayak Pane
hsic_unregister is being called multiple times during two step enumeration process of xmm. In failure cases when enumeration does not complete properly, kernel panic is seen because of extra unregister-ehci device.

2012-08-08arm: tegra: xmm: protect xmm power stateVinayak Pane
Added protection locks for xmm power state. Moving prints outside of spinlock. Revisit spinlock on global flags and rearrange in irq. Avoid kernel crash in case of remote-wakeup detected. Protect ipc_ap_wake_state in xmm on & off.

2012-08-01arm: tegra: xmm: repair ipc_ap_wake_state at resetVinayak Pane
Preparing strict checking for ipc_ap_wake_state during modem initialization. Modify the flashless xmm wake irq part to avoid mixing with flashed modem irq handler. Remove unused init1 workqueue from the driver.

2012-05-16arm: tegra: xmm: baseband modem pm code cleanupVinayak Pane
- Platform data is treated as const and not modified in driver. - Driver specific data is stored and used from a new structure. - Remove support for older firmware version of XMM modem (<1130). - Shortening of names for compliance and to fit in 80 characters. - Organize irq function to reduce indentation.
