Subject: [PATCH 0/2] Add MT8173 MMPLL change rate support
Date: Wed, 8 Jul 2015 16:37:44 +0800 [thread overview]
Message-ID: <1436344666-25645-1-git-send-email-jamesjj.liao@mediatek.com> (raw)
MT8173 MMPLL frequency settings are different from common PLLs.
It needs different post divider settings for some ranges of frequency.
This patch add support for MT8173 MMPLL frequency setting, includes:
1. Add div-rate table for PLLs.
2. Increase the max ost divider setting from 3 (/8) to 4 (/16).
3. Write postdiv and pcw settings at the same time.
