You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From f2b2f6dcd48adf81007b66e39bb7ca21d9bde250 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 27 Sep 2016 08:25:29 +0900 Subject: [PATCH] ASoC: stac9766: fix wrong usage of DECLARE_TLV_DB_LINEAR() As long as reading datasheet of STAC9766/9767, this driver includes wrong usage of DECLARE_TLV_DB_LINEAR(). In "8.1.2. Master Volume Registers", attenuation of lineout volumes is represented in 5 bits by -1.5 dB/step from 0 to -46.5 dB. Thus, 'master_tlv' should be dB step representation. In "8.1.14. Record Gain", gain of volumes is represented in 4 bits by 1.5 dB/step from 0 to 22.5 dB. Thus, 'record_tlv' should be dB step representation. In "8.1.5. PC BEEP Volume", attenuation of volume is represented in 4 bits by -3 dB/step from 0 to 45 dB. Thus, 'beep_tlv' should be dB step representation. In "8.1.7. Stereo or Mic Volume" and so on, gain of volumes is represented in 5 bits by -1.5 dB from 12 to -34.5 dB. Thus, 'mix_tlv' should be dB step representation. Totally, current implementation includes misuse of TLV-related macro. This commit replaces usage of DECLARE_TLV_DB_LINEAR() with SNDRV_CTL_TLVD_DECLARE_DB_SCALE(), to give proper information to applications in user land.
