Subject: [PATCH v3 4/8] mfd: rt5033: Apply preparatory changes before adding rt5033-charger driver
Date: Fri, 28 Apr 2023 01:30:07 +0200 [thread overview]
Message-ID: <af691a402160887645739a5ad4ce5de0613b3d22.1682636929.git.jahau@rocketmail.com> (raw)
In-Reply-To: <cover.1682636929.git.jahau@rocketmail.com>
Order the register blocks to have the masks in descending manner.
Add new defines for constant voltage shift (RT5033_CHGCTRL2_CV_SHIFT),
MIVR mask (RT5033_CHGCTRL4_MIVR_MASK), pre-charge current shift
(RT5033_CHGCTRL4_IPREC_SHIFT), internal timer disable
(RT5033_INT_TIMER_DISABLE), termination disable (RT5033_TE_DISABLE),
CFO disable (RT5033_CFO_DISABLE), UUG disable (RT5033_CHARGER_UUG_DISABLE).
The fast charge timer type needs to be written on mask 0x38
(RT5033_CHGCTRL3_TIMER_MASK). To avoid a bit shift on application, change the
values of the timer types to fit the mask. Added the timout duration as a
comment. And the timer between TIMER8 and TIMER12 is most likely TIMER10, see
e.g. RT5036 [1] page 28 bottom.
Add value options for MIVR (Minimum Input Voltage Regulation).
Move RT5033_TE_ENABLE_MASK to the block "RT5033 CHGCTRL1 register", in order
to have the masks of the register collected there. To fit the naming scheme,
rename it to RT5033_CHGCTRL1_TE_EN_MASK.
Move RT5033_CHG_MAX_CURRENT to the block "RT5033 charger fast-charge current".
Add new defines RT5033_CV_MAX_VOLTAGE and RT5033_CHG_MAX_PRE_CURRENT to the
blocks "RT5033 charger constant charge voltage" and "RT5033 charger pre-charge
current limits".
In include/linux/mfd/rt5033.h, turn power_supply "psy" into a pointer in order
to use it in devm_power_supply_register().
