[PATCH 5/8] interconnect: qcom: icc-rpm: Allow negative QoS offset

[Dmitry Baryshkov]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx>

In some very very very very unfortunate cases, the correct offset of
the QoS registers will be.. negative. One such case is MSM8998, where
The DDR BWMON occupies what-would-be-the-BIMC-base which we usually
take into account with the register calculation, making the actual
BIMC node start at what-would-be-the-BIMC-base+0x300.

In order to keep the calculation code sane, the simplest - however
ugly it may be - solution is to allow the offset to be negative.
