/*
 * This is a workaround command to perform an I2C Scan which is not as
 * simple on an I3C bus as it is with the I2C Shell.
 *
 * This will print "I3" if an address is already assigned for an I3C
 * device and it will print "I2" if an address is already assigned for
 * an I2C device. It will print RS, if the address is reserved according
 * to section 5.1.2.2.5 I3C Target Address Restrictions in I3C v1.1.1.
 *
 * This sends I2C messages without any data (i.e. stop condition after
 * sending just the address). If there is an ACK for the address, it
 * is assumed there is a device present.
 *
 * WARNING: As there is no standard I2C detection command, this code
 * uses arbitrary SMBus commands (namely SMBus quick write and SMBus
 * receive byte) to probe for devices.  This operation can confuse
 * your I2C bus, cause data loss, and is known to corrupt the Atmel
 * AT24RF08 EEPROM found on many IBM Thinkpad laptops.
