Subject: [PATCH 2/2] regulator: pfuze100: update voltage setting for pfuze3000 sw1a
Date: Sat, 17 Mar 2018 14:57:08 +0800	[thread overview]
Message-ID: <1521269828-8874-2-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1521269828-8874-1-git-send-email-Anson.Huang@nxp.com>

Latest pfuze3000 datasheet from:

http://cache.freescale.com/files/analog/doc/data_sheet/PF3000.pdf?fsrch=1&sr=1&pageNum=1

updates sw1a's voltage range, the settings for 1.450V and 1.475V
are replaced with 1.8V and 3.3V:

5b'11110 1.450 (SW1B), 1.8 (SW1A/SW1AB)
5b'11111 1.475 (SW1B), 3.3 (SW1A/SW1AB)

the voltage calculation using steps is NOT available for sw1a now,
use voltage table instead.
