| H A D | cs42l42.h | diff c9f2e3c3ddab87d93cde99f6da10dd00c1d1edb9 Tue May 11 09:52:20 CDT 2021 Vitaly Rodionov <vitalyr@opensource.cirrus.com> ASoC: cs42l42: make HSBIAS_SENSE_EN optional
HSBIAS_SENSE_EN configures HSBIAS output current sense through
the external 2.21-k resistor. HSBIAS_SENSE is hardware feature to reduce
the potential pop noise during the headset plug out slowly. But on some
platforms ESD voltage will affect it causing test to fail, especially
with CTIA headset type. For different hardware setups, a designer might
want to tweak default behavior.
