[alsa-devel] Imx6 i2s master driver without i2c

[nick83ola]

I am using ssi1 because I have an example of setting master mode on sabre
board dts

I have a problem with iomux/pinctrl  I think because

root at icorem6solo:/sys/kernel/debug/pinctrl/20e0000.iomuxc# cat pinmux-pins
|grep audmux
pin 57 (MX6DL_PAD_DISP0_DAT20): 2028000.ssi (GPIO UNCLAIMED) function
audmux group audmux-4
pin 58 (MX6DL_PAD_DISP0_DAT21): 2028000.ssi (GPIO UNCLAIMED) function
audmux group audmux-4
pin 59 (MX6DL_PAD_DISP0_DAT22): 2028000.ssi (GPIO UNCLAIMED) function
audmux group audmux-4
pin 60 (MX6DL_PAD_DISP0_DAT23): 2028000.ssi (GPIO UNCLAIMED) function
audmux group audmux-4

says: GPIO_UNCLAIMED? it is correct??

/sys/kernel/debug/pinctrl/20e0000.iomuxc# cat pinconf-groups |grep -A 1
audmux

0x130b0?
