Yes... But currently in mainline kernel, no dt file for A23/33 uses UART1.
(Lots of the tablets is so low-end that they do not ship with BT support, and
then no support for extra UART is needed)

I found the problem when running mainline kernel on my iNet D978 Rev2 board
tablet. It come with a RTL8723BS.
