[v4] iio: add support for the ad3552r AXI DAC IP

[PATCH v4 02/11] iio: dac: adi-axi-dac: fix wrong register bitfield

Posted by Angelo Dureghello 1 year, 4 months ago

From: Angelo Dureghello <adureghello@baylibre.com>

Fix ADI_DAC_R1_MODE of AXI_DAC_REG_CNTRL_2.

Both generic DAC and ad3552r DAC IPs docs are reporting
bit 5 for it.

Reorder to come before the previous patch.
This want's backporting. The renames are good but too noisy to
backport if we can avoid it.
