From: Vincent Knecht <vincent.kne...@mailoo.org> Enable sound and modem for the Alcatel Idol 3 (4.7"). The setup is similar to most MSM8916 devices, i.e.:
- QDSP6 audio - Microphones via digital/analog codec in MSM8916/PM8916 - WWAN Internet via BAM-DMUX except: - Stereo NXP TFA9890 codecs for speakers on Quaternary MI2S - These are also used as earpieces at the top/bottom. - Asahi Kasei AK4375 headphone codec on Secondary MI2S -> Primary MI2S is not used for playback Signed-off-by: Vincent Knecht <vincent.kne...@mailoo.org> [Stephan: Minor refactoring, add consistent commit message] Signed-off-by: Stephan Gerhold <step...@gerhold.net> --- There are some trivial conflicts unless https://lore.kernel.org/linux-arm-msm/20230921-msm8916-rmem-fixups-v1-3-34d2b6e72...@gerhold.net/ is applied first. But given that there are important fixups for the dynamic reserved memory changes in that series it should preferably get applied before this one anyway. --- .../boot/dts/qcom/msm8916-alcatel-idol347.dts | 171 +++++++++++++++++++++ 1 file changed, 171 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/msm8916-alcatel-idol347.dts b/arch/arm64/boot/dts/qcom/msm8916-alcatel-idol347.dts index fade93c55299..3459145516a1 100644 --- a/arch/arm64/boot/dts/qcom/msm8916-alcatel-idol347.dts +++ b/arch/arm64/boot/dts/qcom/msm8916-alcatel-idol347.dts @@ -3,6 +3,8 @@ /dts-v1/;
