Add the GETMRL/SETMRL and GETMWL/SETMWL CCC commands functions.
The functions are needed to configure maximum read/write length
for the specific I3C device.

i3c: mctp: Extend MCTP o. I3C driver with the TX/RX functions2022-06-01T08:46:09+00:00Oleksandr Shulzhenkooleksandr.shulzhenko.viktorovych@intel.com2022-05-10T15:27:02+00:00urn:sha1:426a368a8790b0561ef81bbd076fcc9c5e7e5ac1
Extend the driver with the functionality necessary to send
and receive MCTP over I3C packets by another component in kernel:
- i3c_mctp_client concept needed to implement packet queue so that
the driver can manage and classify packets for several clients
respectively;
- the function that provides MCTP target EID;
- the functions to alloc and free mctp_i3c_packet;
- the functions to send and receive MCTP packets over I3C.

i3c: Make remove callback return void2021-02-01T23:16:57+00:00Uwe Kleine-Königu.kleine-koenig@pengutronix.de2021-01-28T09:10:48+00:00urn:sha1:dd9267034c0e364b49261c3e0070b863286d1242
The driver core ignores the return value of struct bus_type::remove()
because there is only little that can be done. To simplify the quest to
make this function return void, let struct i3c_driver::remove() return
void, too. This makes it obvious that returning an error code is
a bad idea and future driver authors cannot get that wrong.
Up to now there are no drivers with a remove callback, so there is no
need to adapt drivers.

i3c: add addr and lvr to i2c_dev_desc structure2019-08-11T08:48:28+00:00Przemyslaw Gajpgaj@cadence.com2019-06-22T20:54:59+00:00urn:sha1:b1ac3a4b9aa2f68d498824f1235788e67b51b486
I need to store address and lvr value for I2C devices without static definition
in DT. This allows secondary master to transmit DEFSLVS command properly.
Main changes between v4 and v5:
- Change in defslvs to use addr and lvr from i2c_dev_desc structure
- Change in CDNS and DW drivers to use addr and lvr from i2c_dev_desc structure
