Subject: [PATCH v1] regualtor: pfuze100: correct sw1a/sw2 on pfuze3000
Date: Mon, 15 Jun 2020 05:54:08 +0800 [thread overview]
Message-ID: <1592171648-8752-1-git-send-email-yibin.gong@nxp.com> (raw)
PFUZE100_SWB_REG is not proper for sw1a/sw2, because enable_mask/enable_reg
is not correct. On PFUZE3000, sw1a/sw2 should be the same as sw1a/sw2 on
pfuze100 except that voltages are not linear, so add new PFUZE3000_SW_REG
and pfuze3000_sw_regulator_ops which like the non-linear PFUZE100_SW_REG
and pfuze100_sw_regulator_ops.
Fixes: 1dced996ee70 ("regulator: pfuze100: update voltage setting for pfuze3000 sw1a")
