[PATCH V2 00/14] i3c: mipi-i3c-hci: Fixes for v7.0

[Adrian Hunter]

Hi

Here are some fixes to the MIPI I3C HCI driver.  Please consider them
as fixes for v7.0.

They are mostly related to error recovery and a lack of serialization.

There is a minor conflict with the "i3c: mipi-i3c-hci-pci: Enable IBI
while runtime suspended for Intel controllers" patch set.  So I will
re-send that patch set in in due course.


Changes in V2:

    i3c: mipi-i3c-hci: Use ETIMEDOUT instead of ETIME for timeout errors
	Added Frank's Rev'd-by

    i3c: mipi-i3c-hci: Fix Hot-Join NACK
	Added Frank's Rev'd-by

    i3c: mipi-i3c-hci: Factor out DMA mapping from queuing path
	New patch split out from "i3c: mipi-i3c-hci: Fix race in DMA ring
	enqueue for parallel xfers"

    i3c: mipi-i3c-hci: Consolidate spinlocks
	New patch

    i3c: mipi-i3c-hci: Fix race in DMA ring enqueue for parallel xfers
	Refactor of hci_dma_queue_xfer() to do all DMA mapping first, is
	now a separate earlier patch: "i3c: mipi-i3c-hci: Factor out DMA
	mapping from queuing path"

    i3c: mipi-i3c-hci: Fix race in DMA ring dequeue
	Mutex now defined in struct i3c_hci instead of struct hci_rh_data

    i3c: mipi-i3c-hci: Fix race between DMA ring dequeue and interrupt handler
	Now uses unified spinlock (as per earlier patch "i3c: mipi-i3c-hci:
	Consolidate spinlocks") and extends coverage to the entire interrupt
	handler

    i3c: mipi-i3c-hci: Correct RING_CTRL_ABORT handling in DMA dequeue
	Add Frank's Rev'd-by
	Mutex is now defined in struct i3c_hci

    i3c: mipi-i3c-hci: Add missing TID field to no-op command descriptor
	Add Frank's Rev'd-by

    i3c: mipi-i3c-hci: Restart DMA ring correctly after dequeue abort
	Add Frank's Rev'd-by

    i3c: mipi-i3c-hci: Consolidate common xfer processing logic
	Add Frank's Rev'd-by

    i3c: mipi-i3c-hci: Fix race in DMA error handling in interrupt context
	None

    i3c: mipi-i3c-hci: Fix handling of shared IRQs during early initialization
	Place irq_inactive under the protection of the now unified
	spinlock, eliminating the need for explict memory barriers.
	Correctly position the update of irq_inactive in
	i3c_hci_sync_irq_inactive() to after synchronize_irq()

    i3c: mipi-i3c-hci: Fallback to software reset when bus disable fails
	Add Frank's Rev'd-by
