netif_tx_napi_add() is a variant of netif_napi_add()
It should be used by drivers that use a napi structure
to exclusively poll TX.
We do not want to add this kind of napi in napi_hash[] in following
patches, adding generic busy polling to all NAPI drivers.

Quite a lot of activity in SPI this cycle, almost all of it in drivers
with a few minor improvements and tweaks in the core.
- Updates to pxa2xx to support Intel Broxton and multiple chip selects.
- Support for big endian in the bcm63xx driver.
- Multiple slave support for the mt8173
- New driver for the auxiliary SPI controller in bcm2835 SoCs.
- Support for Layerscale SoCs in the Freescale DSPI driver.

Adjust driver behavior during FW boot. Proper sequence of
events after reset and FW download, is as following:
- FW prepares mailbox structure and reports IRQ "FW_READY"
- driver caches mailbox registers, marks mailbox readiness
- FW sends WMI_FW_READY event, ignore it
- FW sends WMI_READY event with some data
- driver stores relevant data marks FW is operational

are maintained in source ring. Before writing actual CE descriptor,
first shadow copy is filled and then it is copied to CE address space.

consumption by 33KB during on device probing.

The physical address necessary to unmap DMA ('bufferp') is stored
in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
when handling send completion (htc ep id is stored in sk_buff control
buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp}
are removed from CE send completion. This change is needed before removing
the shadow copy of copy engine (CE) descriptors in follow up patch.
