The AD5681R/AD5682R/AD5683/AD5683R are a family of one channel DACs with 12-bit, 14-bit and 16-bit precision respectively. The devices have either no built-in reference, or built-in 2.5V reference. These devices are simmilar to AD5691R/AD5692R/AD5693/AD5693R except that they use the spi interface instead of i2c. Another difference is that in the write control register, DB18 and DB17 are used for setting the power mode, while DB16 is the REF bit. In order to accommodate this change, a new regmap type was defined and checked accordingly.

[ Upstream commit eedf3e3 ] ACPICA commit 1c28da2242783579d59767617121035dafba18c3 This was originally done in NetBSD: NetBSD/src@b69d1ac and is the correct alternative to the smattering of `memcpy`s I previously contributed to this repository. This also sidesteps the newly strict checks added in UBSAN: llvm/llvm-project@7926744 Before this change we see the following UBSAN stack trace in Fuchsia: #0 0x000021afcfdeca5e in

The AD5681R/AD5682R/AD5683/AD5683R are a family of one channel DACs with
12-bit, 14-bit and 16-bit precision respectively. The devices have either
no built-in reference, or built-in 2.5V reference.
These devices are simmilar to AD5691R/AD5692R/AD5693/AD5693R except
that they use the spi interface instead of i2c. Another difference is that
in the write control register, DB18 and DB17 are used for setting the power
mode, while DB16 is the REF bit. In order to accommodate this change, a new
regmap type was defined and checked accordingly.
