[PATCH v2 0/2] clk: meson: mpll: add round closest support

From: Jerome Brunet
Date: Tue May 15 2018 - 13:41:30 EST

ATM, the mpll driver can only round the requested rate down, even if
rounding up would have provided a better approximation of the requested

This patchset adds a flag to enable rounding to the closest rate possible,
even if it means rounding up.

The flag is then enabled on the axg platform to improve the rates provided
to the audio subsystem.

Changes since v1: [0]
* Fix an error in calculation while rounding the rate down
(Thanks Martin for reporting it)
