Subject: [PATCH v4 3/8] mfd: rt5033: Fix STAT_MASK, HZ_MASK and AICR defines
Date: Sat,  6 May 2023 17:54:30 +0200	[thread overview]
Message-ID: <20230506155435.3005-4-jahau@rocketmail.com> (raw)
In-Reply-To: <20230506155435.3005-1-jahau@rocketmail.com>

The charger state mask RT5033_CHG_STAT_MASK should be 0x30 [1][2].

The high impedance mask RT5033_RT_HZ_MASK is actually value 0x02 [3] and is
assosiated to the RT5033 CHGCTRL1 register [4]. Accordingly also change
RT5033_CHARGER_HZ_ENABLE to 0x02 to avoid the need of a bit shift upon
application.

For input current limiting AICR mode, the define for the 1000 mA step was
missing [5]. Additionally add the define for DISABLE option. Concerning the
mask, remove RT5033_AICR_MODE_MASK because there is already
RT5033_CHGCTRL1_IAICR_MASK further up. They are redundant and the upper one
makes more sense to have the masks of a register colleted there as an
overview.
