[PATCH 0/3] qcom: serial_msm: calculate UARTDM_CSR automatically

[Caleb Connolly]

The msm serial UART controller has a bit clock divider register which
much be programmed based on the UART clock. This changes per soc and
currently is expected to be specified in DT or otherwise selected per
board.

This series fixes the apq8016 and ipq4019 clock drivers to return the
programmed UART clock rate in clk_set_rate(), it then uses this clock
rate and the hardcoded baud rate supported by this driver to calculate
the correct value for the UARTDM_CSR register.
