+ * This method is optional.
+ * @attach_i3c_dev: called every time an I3C device is attached to the bus. It
+ * can be after a DAA or when a device is statically declared

+ * and the dynamic address will be 0.

+ * This is a good place to attach master controller specific

+ * changed. It can be because the device has been powered
+ * down and has lost its address, or it can happen when a
+ * device had a static address and has been assigned a
+ * dynamic address with SETDASA.
+ * This method is optional.
+ * @detach_i3c_dev: called when an I3C device is detached from the bus. Usually
+ * happens when the master device is unregistered.
+ * This method is optional.
+ * @do_daa: do a DAA (Dynamic Address Assignment) procedure. This is procedure
+ * should send an ENTDAA CCC command and then add all devices
+ * discovered sure the DAA using i3c_master_add_i3c_dev_locked().
+ * Add devices added with i3c_master_add_i3c_dev_locked() will then be
+ * attached or re-attached to the controller.
+ * This method is mandatory.
+ * @supports_ccc_cmd: should return true if the CCC command is supported, false
+ * otherwise.
+ * This method is optional, if not provided the core assumes
+ * all CCC commands are supported.
+ * @send_ccc_cmd: send a CCC command
+ * This method is mandatory.

+ * buffers, they should use the i2c_get_dma_safe_msg_buf()

+ * @i2c_funcs: expose the supported I2C functionalities.

+ * an IBI handler and the constraints of the IBI (maximum payload
+ * length and number of pre-allocated slots).
+ * Some controllers support less IBI-capable devices than regular
+ * devices, so this method might return -%EBUSY if there's no
+ * more space for an extra IBI registration
+ * This method is optional.
+ * @free_ibi: free an IBI previously requested with ->request_ibi(). The IBI
+ * should have been disabled with ->disable_irq() prior to that
+ * This method is mandatory only if ->request_ibi is not NULL.
+ * @enable_ibi: enable the IBI. Only valid if ->request_ibi() has been called
+ * prior to ->enable_ibi(). The controller should first enable
+ * the IBI on the controller end (for example, unmask the hardware
+ * IRQ) and then send the ENEC CCC command (with the IBI flag set)
+ * to the I3C device.
+ * This method is mandatory only if ->request_ibi is not NULL.
+ * @disable_ibi: disable an IBI. First send the DISEC CCC command with the IBI
+ * flag set and then deactivate the hardware IRQ on the
+ * controller end.
+ * This method is mandatory only if ->request_ibi is not NULL.
+ * @recycle_ibi_slot: recycle an IBI slot. Called every time an IBI has been

*
- * The page_fault() callback must migrate page back, from device memory to

- * conditions happen, the page_fault() callback must return VM_FAULT_SIGBUS and
- * set the CPU page table entry to "poisoned".
- *
- * Note that because memory cgroup charges are transferred to the device memory,
- * this should never fail due to memory restrictions. However, allocation
- * of a regular system page might still fail because we are out of memory. If
- * that happens, the page_fault() callback must return VM_FAULT_OOM.
- *
- * The page_fault() callback can also try to migrate back multiple pages in one
- * chunk, as an optimization. It must, however, prioritize the faulting address
- * over all the others.
- *
- *
* The page_free() callback is called once the page refcount reaches 1
* (ZONE_DEVICE pages never reach 0 refcount unless there is a refcount bug.
* This allows the device driver to implement its own memory management.)
