MFD cells definitely has less impact than regmap_range and regmap_irq.
I agree, there's no point in having a completely new 
static const struct mfd_cell da9063l_devs[] = { ... }  for DA9063L

Looking at this further, there is also a new IRQ regmap.
Again this comes down to whether a full chip model is needed or not. If not, 
then the IRQ map does not

There's potentially more to this file. Without an RTC the regmap access tables 
would change and the
usual DA9063 (BB silicon) tables would become invalid.
The tables for da9063_bb_readable_ranges, da9063_bb_writeable_ranges, 
da9063_bb_volatile_ranges,
would need to be updated for DA9063L, if a new chip model was needed.

The new ranges would be this (see below), and would remove any RTC accesses in 
the new chip model.

static const struct regmap_range da9063l_bb_readable_ranges[] = {
{
.range_min = DA9063_REG_PAGE_CON,
.range_max = DA9063_REG_MON_A10_RES,

.range_min = DA9063_REG_SEQ,
.range_max = DA9063_REG_ID_32_31,

.range_min = DA9063_REG_SEQ_A,
.range_max = DA9063_REG_AUTO3_LOW,

.range_min = DA9063_REG_CHIP_ID,
.range_max = DA9063_REG_CHIP_VARIANT,
},
};

static const struct regmap_range da9063l_bb_writeable_ranges[] = {
{

}, {
.range_min = DA9063_REG_SEQ,
.range_max = DA9063_REG_ID_32_31,

.range_min = DA9063_REG_SEQ_A,
.range_max = DA9063_REG_AUTO3_LOW,

}, {
.range_min = DA9063_BB_REG_GP_ID_0,
.range_max = DA9063_BB_REG_GP_ID_19,
},
};

static const struct regmap_range da9063l_bb_volatile_ranges[] = {
{
.range_min = DA9063_REG_PAGE_CON,
.range_max = DA9063_REG_EVENT_D,
}, {
.range_min = DA9063_REG_CONTROL_A,
.range_max = DA9063_REG_CONTROL_B,

.range_min = DA9063_REG_ADC_RES_L,
.range_max = DA9063_REG_MON_A10_RES,
}, {
.range_min = DA9063_REG_SEQ,
.range_max = DA9063_REG_SEQ,
}, {
.range_min = DA9063_REG_EN_32K,
.range_max = DA9063_REG_EN_32K,
}, {
.range_min = DA9063_BB_REG_MON_REG_5,
.range_max = DA9063_BB_REG_MON_REG_6,
},
};

However this is a larger and more wide-ranging change compared to the one 
proposed by Marek,
and would require other alterations to fit this in. Also I'm undecided to what 
it would really add
apart from a new chip model: I have been told accessing the DA9063 RTC register 
locations has
no effect in the DA9063L.

If the maintainers are happy with this, and if a chip model addition is really 
needed in future
it can be added later if required.
