Subject: [PATCH V1] mfd: da9061: fix to remove BBAT_CONT register from chip
 model

From: Steve Twiss <stwiss.opensource@...semi.com>

Remove the register DA9062AA_BBAT_CONT (0x0C5) from the DA9061 chip model
regmap access ranges. This applies to both da9061_aa_readable_ranges[]
and da9061_aa_writeable_ranges[].

This change is to correct the DA9061 chip model and align it with the
latest DA9061 Datasheet.

This register previously appeared in the DA9061 Datasheet, Revision 3.2,
01-Mar-2016 and has been removed from later DA9061 datasheet from Dialog,
Revision 3.3, 04-Apr-2017.

Hi Lee,

This is a fix to remove DA9062AA_BBAT_CONT register from the DA9061
regmap read/write access tables. It only applies to the DA9061 chip,
and does not affect the DA9062.

No existing kernel code tries to access this register, so the change is
just a formality to correct the DA9061 chip model and align it with the
DA9061 Datasheet.

This patch applies against linux-next and v4.12-rc3

Regards,
Steve Twiss, Dialog Semiconductor
