Remove my soon bouncing email address. Also remove the "Contact:" line in file header. The MAINTAINERS file is a better place to find the contact person anyway. Signed-off-by:

Fix the failing merge in net-next by reverting the last net-next merge for caif_hsi.c and then merge in the commit: "caif-hsi: Bugfix - Piggyback'ed embedded CAIF frame lost" from the net repository. The commit:"caif-hsi: Add missing return in error path" from net repository was dropped, as it changed code previously removed in the net-next repository. Signed-off-by:

Remove use of module parameters on caif hsi device, as rtnl configuration parameters are already supported. All caif hsi configuration data is put in cfhsi_config, and default values in hsi_default_config. Signed-off-by:

Remove use of struct platform_device, and replace it with struct cfhsi_ops. Updated variable names in the same spirit: cfhsi_get_dev to cfhsi_get_ops, cfhsi->dev to cfhsi->ops and, cfhsi->dev.drv to cfhsi->ops->cb_ops. Signed-off-by:

Add RTNL support for managing the caif hsi interface. The HSI HW interface is no longer registering as a device, instead we use symbol_get to get hold of the HSI API. Signed-off-by:

Implement aggregation algorithm, combining more data into a single HSI transfer. 4 different traffic categories are supported: 1. TC_PRIO_CONTROL .. TC_PRIO_MAX (CTL) 2. TC_PRIO_INTERACTIVE (VO) 3. TC_PRIO_INTERACTIVE_BULK (VI) 4. TC_PRIO_BESTEFFORT, TC_PRIO_BULK, TC_PRIO_FILLER (BEBK) Signed-off-by:

Some platforms do not allow to put HSI block into low-power mode when FIFO is not empty. The patch flushes (by reading) FIFO at wake down sequence. Asynchronous read and write is implemented for that. As a side effect this will also greatly improve performance. Signed-off-by:

Under stressed conditions a race could happen when del_timer_sync() was called from softirq context at the same time when mod_timer_pending() for the same timer was called from the workqueue. This leaded to a state mismatch in the CAIF HSI driver and following unexpected link wakeup procedure. The fix puts del_timer_sync() and mod_timer_pending() calls under a spin lock to protect against the race condition. Signed-off-by:
