10 * The P2WI controller looks like an SMBus controller which only supports byte
13 * - it supports only one slave device, and thus drop the address field
14 * - it adds a parity bit every 8bits of data
15 * - only one read access is required to read a byte (instead of a write
17 * - there's no Ack bit after each byte transfer
