In the device-tree the sound node is so configured:

model = "imx6-ek360-sgtl5000";
ssi-controller = <&ssi1>;
audio-codec = <&sgtl5000>;
audio-routing =
"MIC_IN", "Mic Jack",
"Mic Jack", "Mic Bias",
"Headphone Jack", "HP_OUT";
mux-int-port = <1>;
mux-ext-port = <4>;
This should be mux-ext-port = <3>;
I've already modified now.
I do not know about the mux-int-port or mux-ext-port. The only thing I know
is the hardware guy told me he routed the ssi (CLK and DAT) to:
AUD3_TXC_R (i2s_sclk)
AUD3_TXD (i2s_din)
AUD3_TXFS (i2s_lrclk)
AUD3_RXD (i2s_dout)
SYS_MCLK (GPIO_0_CLKO sys_mclk)
since you are using AUD3 pins.
So, are they good?
My only concern is the value after the MSYS_CLK (GPIO_0_CCM_CLK01). It
is 0x030b0. Is this correct for output clock signal?
So I configured the pinmux for audio in the following way:
pinctrl_audmux: audmuxgrp {
fsl,pins = <
/* SGTL5000 sys_mclk */
MX6QDL_PAD_GPIO_0__CCM_CLKO1
0x030b0
The remaining pins seems to be configured as a lot of boards in the
current 4.12-rc7 kernel. So I can assume they are good.
MX6QDL_PAD_CSI0_DAT4__AUD3_TXC
0x130b0
MX6QDL_PAD_CSI0_DAT5__AUD3_TXD
0x110b0
MX6QDL_PAD_CSI0_DAT6__AUD3_TXFS
0x130b0
MX6QDL_PAD_CSI0_DAT7__AUD3_RXD
0x130b0
>;
};
They should be good.
How can I check or dump the SGTL5000 registers?
cat /sys/kernel/debug/regmap/xxx
I am missing the regmap. Should I configure kernel with additional CONFIG_ ?
I started from the imxv6_imxv7_defconfig, then modified to have the
correct drivers module as built-in or dynamic.
Maybe am I missing something else??? :-(
