<p>Thanks I addressed the comments except for one pending a response.</p>
<p>Also sorry I added one more commit to address the case where <code>uart_write()</code> is followed immediately by <code>uart_poweroff()</code> by blocking until TX is complete. This is consistent with the stm32 driver for example.</p>
