Subject: [PATCH 0/3] Clean up RK3328 audio codec GPIO control
Date: Thu, 6 Feb 2020 01:07:10 +0000 [thread overview]
Message-ID: <cover.1580950046.git.robin.murphy@arm.com> (raw)
Hi all,
Investigating the RK3328 GPIO_MUTE pin in the context of boards that use
it to control a regulator has highlighted that the audio codec driver
currently has some hard-coded implicit control of that pin. Fortunately
those boards don't currently enable the audio codec, because it would be
pretty terrible if playing audio changed the SD card I/O voltage. This
is a first crack at making things better.
Robin.
