Call :c:type:`i3c_master_controller_ops->bus_init\(\) ` method to initialize the master controller. That's usually where the bus mode is selected (pure bus or mixed fast/slow bus) 3. Instruct all devices on the bus to drop their dynamic address. This is particularly important when the bus was previously configured by someone else (for example the bootloader) 4. Disable all slave events. 5. Reserve address slots for I3C devices with init_dyn_addr. And if devices also have static_addr, try to pre-assign dynamic addresses requested by the FW with SETDASA and attach corresponding statically defined I3C devices to the master. 6. Do a DAA (Dynamic Address Assignment) to assign dynamic addresses to all remaining I3C devices Once this is done, all I3C and I2C devices should be usable. **Return** a 0 in case of success, an negative error code otherwise.h](j)}(h**Parameters**h]j)}(hj+h]h Parameters}(hj+hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj+ubah}(h]h ]h"]h$]h&]uh1jhd/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:7: ./drivers/i3c/master.chM0 hj+ubj0)}(hhh]j5)}(hJ``struct i3c_master_controller *master`` main master initializing the bus h](j;)}(h(``struct i3c_master_controller *master``h]jA)}(hj4+h]h$struct i3c_master_controller *master}(hj6+hhhNhNubah}(h]h ]h"]h$]h&]uh1j@hj2+ubah}(h]h ]h"]h$]h&]uh1j:hd/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:7: ./drivers/i3c/master.chM- hj.+ubjW)}(hhh]j)}(h main master initializing the bush]h main master initializing the bus}(hjM+hhhNhNubah}(h]h ]h"]h$]h&]uh1jhjI+hM- hjJ+ubah}(h]h ]h"]h$]h&]uh1jVhj.+ubeh}(h]h ]h"]h$]h&]uh1j4hjI+hM- hj++ubah}(h]h ]h"]h$]h&]uh1j/hj+ubj)}(h**Description**h]j)}(hjo+h]h Description}(hjq+hhhNhNubah}(h]h ]h"]h$]h&]uh1jhjm+ubah}(h]h ]h"]h$]h&]uh1jhd/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:7: ./drivers/i3c/master.chM/ hj+ubj)}(hWThis function is following all initialisation steps described in the I3C specification:h]hWThis function is following all initialisation steps described in the I3C specification:}(hj+hhhNhNubah}(h]h ]h"]h$]h&]uh1jhd/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:7: ./drivers/i3c/master.chM. hj+ubhenumerated_list)}(hhh](jm()}(hbAttach I2C devs to the master so that the master can fill its internal device table appropriately h]j)}(haAttach I2C devs to the master so that the master can fill its internal device table appropriatelyh]haAttach I2C devs to the master so that the master can fill its internal device table appropriately}(hj+hhhNhNubah}(h]h ]h"]h$]h&]uh1jhd/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:7: ./drivers/i3c/master.chM1 hj+ubah}(h]h ]h"]h$]h&]uh1jl(hj+ubjm()}(hCall :c:type:`i3c_master_controller_ops->bus_init\(\) ` method to initialize the master controller.

You should at least call master_set_info() from there and set the bus mode. You can also put controller specific initialization in there. This method is mandatory. ``bus_cleanup`` cleanup everything done in :c:type:`i3c_master_controller_ops->bus_init\(\) `. 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 by the FW, in which case it will only have a static address and the dynamic address will be 0. When this function is called, device information have not been retrieved yet. This is a good place to attach master controller specific data to I3C devices. This method is optional. ``reattach_i3c_dev`` called every time an I3C device has its addressed 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. ``i3c_xfers`` do one or several I3C SDR or HDR transfers. This method is mandatory. ``attach_i2c_dev`` called every time an I2C device is attached to the bus. This is a good place to attach master controller specific data to I2C devices. This method is optional. ``detach_i2c_dev`` called when an I2C device is detached from the bus. Usually happens when the master device is unregistered. This method is optional. ``i2c_xfers`` do one or several I2C transfers. Note that, unlike i3c transfers, the core does not guarantee that buffers attached to the transfers are DMA-safe. If drivers want to have DMA-safe buffers, they should use the i2c_get_dma_safe_msg_buf() and i2c_put_dma_safe_msg_buf() helpers provided by the I2C framework. This method is mandatory. ``request_ibi`` attach an IBI handler to an I3C device. This implies defining 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 processed by its handler. The IBI slot should be put back in the IBI slot pool so that the controller can re-use it for a future IBI This method is mandatory only if ->request_ibi is not NULL. ``enable_hotjoin`` enable hot join event detect. ``disable_hotjoin`` disable hot join event detect. ``set_speed`` adjust I3C open drain mode timing. ``set_dev_nack_retry`` configure device NACK retry count for the master controller.h](j)}(h**Definition**::h](j)}(h**Definition**h]h Definition}(hjghhhNhNubah}(h]h ]h"]h$]h&]uh1jhjgubh:}(hjghhhNhNubeh}(h]h ]h"]h$]h&]uh1jhj/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:9: ./include/linux/i3c/master.hhMhjgubj(N)}(hXstruct i3c_master_controller_ops { int (*bus_init)(struct i3c_master_controller *master); void (*bus_cleanup)(struct i3c_master_controller *master); int (*attach_i3c_dev)(struct i3c_dev_desc *dev); int (*reattach_i3c_dev)(struct i3c_dev_desc *dev, u8 old_dyn_addr); void (*detach_i3c_dev)(struct i3c_dev_desc *dev); int (*do_daa)(struct i3c_master_controller *master); bool (*supports_ccc_cmd)(struct i3c_master_controller *master, const struct i3c_ccc_cmd *cmd); int (*send_ccc_cmd)(struct i3c_master_controller *master, struct i3c_ccc_cmd *cmd); int (*i3c_xfers)(struct i3c_dev_desc *dev, struct i3c_xfer *xfers, int nxfers, enum i3c_xfer_mode mode); int (*attach_i2c_dev)(struct i2c_dev_desc *dev); void (*detach_i2c_dev)(struct i2c_dev_desc *dev); int (*i2c_xfers)(struct i2c_dev_desc *dev, struct i2c_msg *xfers, int nxfers); int (*request_ibi)(struct i3c_dev_desc *dev, const struct i3c_ibi_setup *req); void (*free_ibi)(struct i3c_dev_desc *dev); int (*enable_ibi)(struct i3c_dev_desc *dev); int (*disable_ibi)(struct i3c_dev_desc *dev); void (*recycle_ibi_slot)(struct i3c_dev_desc *dev, struct i3c_ibi_slot *slot); int (*enable_hotjoin)(struct i3c_master_controller *master); int (*disable_hotjoin)(struct i3c_master_controller *master); int (*set_speed)(struct i3c_master_controller *master, enum i3c_open_drain_speed speed); int (*set_dev_nack_retry)(struct i3c_master_controller *master, unsigned int dev_nack_retry_cnt); };h]hXstruct i3c_master_controller_ops { int (*bus_init)(struct i3c_master_controller *master); void (*bus_cleanup)(struct i3c_master_controller *master); int (*attach_i3c_dev)(struct i3c_dev_desc *dev); int (*reattach_i3c_dev)(struct i3c_dev_desc *dev, u8 old_dyn_addr); void (*detach_i3c_dev)(struct i3c_dev_desc *dev); int (*do_daa)(struct i3c_master_controller *master); bool (*supports_ccc_cmd)(struct i3c_master_controller *master, const struct i3c_ccc_cmd *cmd); int (*send_ccc_cmd)(struct i3c_master_controller *master, struct i3c_ccc_cmd *cmd); int (*i3c_xfers)(struct i3c_dev_desc *dev, struct i3c_xfer *xfers, int nxfers, enum i3c_xfer_mode mode); int (*attach_i2c_dev)(struct i2c_dev_desc *dev); void (*detach_i2c_dev)(struct i2c_dev_desc *dev); int (*i2c_xfers)(struct i2c_dev_desc *dev, struct i2c_msg *xfers, int nxfers); int (*request_ibi)(struct i3c_dev_desc *dev, const struct i3c_ibi_setup *req); void (*free_ibi)(struct i3c_dev_desc *dev); int (*enable_ibi)(struct i3c_dev_desc *dev); int (*disable_ibi)(struct i3c_dev_desc *dev); void (*recycle_ibi_slot)(struct i3c_dev_desc *dev, struct i3c_ibi_slot *slot); int (*enable_hotjoin)(struct i3c_master_controller *master); int (*disable_hotjoin)(struct i3c_master_controller *master); int (*set_speed)(struct i3c_master_controller *master, enum i3c_open_drain_speed speed); int (*set_dev_nack_retry)(struct i3c_master_controller *master, unsigned int dev_nack_retry_cnt); };}hjhsbah}(h]h ]h"]h$]h&]hhuh1j'Nhj/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:9: ./include/linux/i3c/master.hhMhjgubj)}(h **Members**h]j)}(hj%hh]hMembers}(hj'hhhhNhNubah}(h]h ]h"]h$]h&]uh1jhj#hubah}(h]h ]h"]h$]h&]uh1jhj/var/lib/git/docbuild/linux/Documentation/driver-api/i3c/master-driver-api:9: ./include/linux/i3c/master.hhMhjgubj0)}(hhh](j5)}(h``bus_init`` hook responsible for the I3C bus initialization.
