 some, but not all of the other indices changing.

+Sometimes you need to ensure that a subsequent call to :c:func:`xa_store`
+will not need to allocate memory.  The :c:func:`xa_reserve` function
+will store a reserved entry at the indicated index.  Users of the normal
+API will see this entry as containing ``NULL``.  If you do not need to
+use the reserved entry, you can call :c:func:`xa_release` to remove the
+unused entry.  If another user has stored to the entry in the meantime,
+:c:func:`xa_release` will do nothing; if instead you want the entry to
+become ``NULL``, you should use :c:func:`xa_erase`.
+
+If all entries in the array are ``NULL``, the :c:func:`xa_empty` function
+will return ``true``.
+
 Finally, you can remove all entries from an XArray by calling
 :c:func:`xa_destroy`.  If the XArray entries are pointers, you may wish
 to free the entries first.  You can do this by iterating over all present
 entries in the XArray using the :c:func:`xa_for_each` iterator.

+Allocating XArrays
+------------------
+
+If you use :c:func:`DEFINE_XARRAY_ALLOC` to define the XArray, or
+initialise it by passing ``XA_FLAGS_ALLOC`` to :c:func:`xa_init_flags`,
+the XArray changes to track whether entries are in use or not.

 You can call :c:func:`xa_alloc` to store the entry at any unused index
 in the XArray.  If you need to modify the array from interrupt context,
 you can use :c:func:`xa_alloc_bh` or :c:func:`xa_alloc_irq` to disable
-interrupts while allocating the ID.  Unlike :c:func:`xa_store`, allocating
-a ``NULL`` pointer does not delete an entry.  Instead it reserves an
-entry like :c:func:`xa_reserve` and you can release it using either
-:c:func:`xa_erase` or :c:func:`xa_release`.  To use ID assignment, the
-XArray must be defined with :c:func:`DEFINE_XARRAY_ALLOC`, or initialised
-by passing ``XA_FLAGS_ALLOC`` to :c:func:`xa_init_flags`,
+interrupts while allocating the ID.
+
+Using :c:func:`xa_store`, :c:func:`xa_cmpxchg` or :c:func:`xa_insert`
+will mark the entry as being allocated.  Unlike a normal XArray, storing
+``NULL`` will mark the entry as being in use, like :c:func:`xa_reserve`.
+To free an entry, use :c:func:`xa_erase` (or :c:func:`xa_release` if
+you only want to free the entry if it's ``NULL``).
+
+You cannot use ``XA_MARK_0`` with an allocating XArray as this mark
+is used to track whether an entry is free or not.  The other marks are

+Description
+-----------
+
+i2c-nvidia-gpu is a driver for I2C controller included in NVIDIA Turing
+and later GPUs and it is used to communicate with Type-C controller on GPUs.
+
+If your 'lspci -v' listing shows something like the following,
+
+01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
+
+then this driver should support the I2C controller of your GPU.
