Merge series "ASoC: qcom: Add support for SC7180 lpass variant" from Rohit kumar <rohitkr@codeaurora.org>:
This patch chain add audio support for SC7180 soc by doing the required modification in existing common lpass-cpu/lpass-platform driver. This also fixes some concurrency issue. This patch series is already tested by Srinivas on Dragon Board 410c. Changes since v5: - Fixed remove api in lpass-sc7180.c - Addressed comments by Rob in yaml Documentation. Ajit Pandey (4): ASoC: qcom: Add common array to initialize soc based core clocks ASoC: qcom: lpass-platform: Replace card->dev with component->dev include: dt-bindings: sound: Add sc7180-lpass bindings header ASoC: qcom: lpass-sc7180: Add platform driver for lpass audio Rohit kumar (8): ASoC: qcom: lpass-cpu: Move ahbix clk to platform specific function ASoC: qcom: lpass-platform: fix memory leak ASoC: qcom: lpass: Use regmap_field for i2sctl and dmactl registers ASoC: qcom: lpass-cpu: fix concurrency issue dt-bindings: sound: lpass-cpu: Add sc7180 lpass cpu node ASoC: qcom: lpass-cpu: Use platform_get_resource ASoC: qcom: lpass-platform: Use platform_get_irq dt-bindings: sound: lpass-cpu: Move to yaml format .../devicetree/bindings/sound/qcom,lpass-cpu.txt | 79 -------- .../devicetree/bindings/sound/qcom,lpass-cpu.yaml | 189 ++++++++++++++++++ include/dt-bindings/sound/sc7180-lpass.h | 10 + sound/soc/qcom/Kconfig | 5 + sound/soc/qcom/Makefile | 2 + sound/soc/qcom/lpass-apq8016.c | 86 ++++++-- sound/soc/qcom/lpass-cpu.c | 204 ++++++++++--------- sound/soc/qcom/lpass-ipq806x.c | 67 +++++++ sound/soc/qcom/lpass-lpaif-reg.h | 157 ++++++++------- sound/soc/qcom/lpass-platform.c | 155 +++++++++++---- sound/soc/qcom/lpass-sc7180.c | 216 +++++++++++++++++++++ sound/soc/qcom/lpass.h | 63 +++++- 12 files changed, 934 insertions(+), 299 deletions(-) delete mode 100644 Documentation/devicetree/bindings/sound/qcom,lpass-cpu.txt create mode 100644 Documentation/devicetree/bindings/sound/qcom,lpass-cpu.yaml create mode 100644 include/dt-bindings/sound/sc7180-lpass.h create mode 100644 sound/soc/qcom/lpass-sc7180.c -- Qualcomm India Private Limited, on behalf of Qualcomm Innovation Center, Inc., is a member of Code Aurora Forum, a Linux Foundation Collaborative Project.

-* Qualcomm Technologies LPASS CPU DAI
-
-This node models the Qualcomm Technologies Low-Power Audio SubSystem (LPASS).
-
-Required properties:
-
-- compatible : "qcom,lpass-cpu" or "qcom,apq8016-lpass-cpu"
-- clocks : Must contain an entry for each entry in clock-names.
-- clock-names : A list which must include the following entries:
- * "ahbix-clk"
- * "mi2s-osr-clk"
- * "mi2s-bit-clk"
- : required clocks for "qcom,lpass-cpu-apq8016"
- * "ahbix-clk"
- * "mi2s-bit-clk0"
- * "mi2s-bit-clk1"
- * "mi2s-bit-clk2"
- * "mi2s-bit-clk3"
- * "pcnoc-mport-clk"
- * "pcnoc-sway-clk"
-
-- interrupts : Must contain an entry for each entry in
- interrupt-names.
-- interrupt-names : A list which must include the following entries:
- * "lpass-irq-lpaif"
-- pinctrl-N : One property must exist for each entry in
- pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
- for details of the property values.
-- pinctrl-names : Must contain a "default" entry.
-- reg : Must contain an address for each entry in reg-names.
-- reg-names : A list which must include the following entries:
- * "lpass-lpaif"
-- #address-cells : Must be 1
-- #size-cells : Must be 0
-
-
-
-Optional properties:
-
-- qcom,adsp : Phandle for the audio DSP node
-
-By default, the driver uses up to 4 MI2S SD lines, for a total of 8 channels.
-The SD lines to use can be configured by adding subnodes for each of the DAIs.
-
-Required properties for each DAI (represented by a subnode):
-- reg : Must be one of the DAI IDs
- (usually part of dt-bindings header)
-- qcom,playback-sd-lines: List of serial data lines to use for playback
- Each SD line should be represented by a number from 0-3.
-- qcom,capture-sd-lines : List of serial data lines to use for capture
- Each SD line should be represented by a number from 0-3.
-
-Note that adding a subnode changes the default to "no lines configured",
-so both playback and capture lines should be configured when a subnode is added.
-
-Example:
-
-lpass@28100000 {
- compatible = "qcom,lpass-cpu";
- clocks = <&lcc AHBIX_CLK>, <&lcc MI2S_OSR_CLK>, <&lcc MI2S_BIT_CLK>;
- clock-names = "ahbix-clk", "mi2s-osr-clk", "mi2s-bit-clk";
- interrupts = <0 85 1>;
- interrupt-names = "lpass-irq-lpaif";
- pinctrl-names = "default", "idle";
- pinctrl-0 = <&mi2s_default>;
- pinctrl-1 = <&mi2s_idle>;
- reg = <0x28100000 0x10000>;
- reg-names = "lpass-lpaif";
- qcom,adsp = <&adsp>;
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- /* Optional to set different MI2S SD lines */
- dai@3 {
- reg = <MI2S_QUATERNARY>;
- qcom,playback-sd-lines = <0 1>;
- };
-};
