Subject: [PATCH 3/3] regulator: qcom_smd: Avoid overlapping linear voltage ranges
Date: Mon, 11 Jul 2016 14:50:09 -0700 [thread overview]
Message-ID: <20160711215009.4519-4-sboyd@codeaurora.org> (raw)
In-Reply-To: <20160711215009.4519-1-sboyd@codeaurora.org>
The pm8x41_hfsmps ranges overlap. The first range is from 375000
to 1562500:
375000 + (95 * 12500) == 1562500
and the second range starts at 1550000. Interestingly, the second
range ends at the correct value when it's set to be the
appropriate start value, 1575000:
1575000 + ((158 - 96) * 25000) == 3125000
