Does this card not work for older i.MXs (which had the same SSI/AUDMUX combination as the majority of the i.MX6 family) as well?
It's widely used in older i.MXs according to their DTS files. So it should be safer to just leave SSI over here.
Nothing prevents you to enable the SSI driver on any i.MX6 module.
What about i.MX2, 3 and 5 series? Will they still be able to enable SSI without changing .config file as usual?
The only change I made is to select the SAI driver instead of the SSI driver on i.MX6UL because the i.MX6UL does not have an SSI unit!
And I actually doubt the feasibility of running this driver with i.MX6UL as there might not be an AUDMUX on i.MX6UL since it does not have SSI any more while the driver always touches the address space of AUDMUX which may not exist on i.MX6UL.
#define this driver
Your change is applied to "SND_SOC_IMX_SGTL5000" whose corresponding driver is the imx-sgtl5000.c file.
The FSL_SAI driver does not touch the audmux address space in any way.
This imx-sgtl5000 driver does access AUDMUX registers. And I thought you tried to use this one which made me very confused.
The simple-card audio driver works perfectly well with the FSL_SAI driver on i.MX6UL.
It seems like you are using simple-card while letting the other driver (imx-sgtl5000) select SAI for you. It doesn't sound so right to me.
