From: Alban Bedel Date: Tue, 21 Oct 2014 15:33:29 +0000 (+0200) Subject: ASoC: tegra: Read and use the GPIO flags of the headphone detect X-Git-Tag: firefly_0821_release~176^2~2610^2~38^2~9^3 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=469cda294dac1c4128e9adcb0a94636bc0cb280e;p=firefly-linux-kernel-4.4.55.git ASoC: tegra: Read and use the GPIO flags of the headphone detect The headphone detect was hardcoded to low-active, use the flags from DT to allow high-active as well.
