This patch series introduces support for the AMD I3C master controller, including the device tree binding and driver implementation.
Changes for V2: Updated commit subject and description. Moved allOf to after required. Removed xlnx,num-targets property. Added mixed mode support with clock configuration. Converted smaller functions into inline functions. Used FIELD_GET() in xi3c_get_response(). Updated xi3c_master_rd_from_rx_fifo() to use cmd->rx_buf. Used parity8() for address parity calculation. Added guards for locks. Dropped num_targets and updated xi3c_master_do_daa(). Used __free(kfree) in xi3c_master_send_bdcast_ccc_cmd(). Dropped PM runtime support. Updated xi3c_master_read() and xi3c_master_write() with xi3c_is_resp_available() check. Created separate functions: xi3c_master_init() and xi3c_master_reinit(). Used xi3c_master_init() in bus initialization and xi3c_master_reinit() in error paths. Added DAA structure to xi3c_master structure. Changes for V3: Updated commit description. Corrected the order of properties and removed resets property. Added compatible to required list. Added interrupts to example. Resolved merge conflicts. Changes for V4: Added h/w documentation details. Updated timeout macros. Removed type casting for xi3c_is_resp_available() macro. Used ioread32() and iowrite32() instead of readl() and writel() to keep consistency. Read XI3C_RESET_OFFSET reg before udelay(). Removed xi3c_master_free_xfer() and directly used kfree(). Skipped checking return value of i3c_master_add_i3c_dev_locked(). Used devm_mutex_init() instead of mutex_init(). Changes for V5: Renamed the xlnx,axi-i3c.yaml file into xlnx,axi-i3c-1.0.yaml. Used GENMASK_ULL for PID mask as it's 64bit mask.
