Some of the timeout values used in the driver are not long enough to handle worst-case scenarios so they need to be recalculated. The time to wait for the FIFO to drain past the low-watermark is now 20 ms because it can take around 14.35 ms to send 95 bytes (127 bytes in full FIFO minus 32 bytes where the low-watermark interrupt will fire). 95 bytes will take around 14.35 ms at 6.62 kbps (the lowest supported bit rate used by ISO/IEC 15693) so 20 ms should be a safe value. The time to wait before issuing an EOF to complete an ISO/IEC 15693 write or lock command is 40 ms-- 20 ms to drain the FIFO and another 20 ms to ensure the wait is long enough before sending an EOF.
