Looking at the Multi-Function Pin Mapping and Control table, function 1 is MACLINK1, function 2 is SCL13, function 3 is SGPS2CK, and I assume function 4 would be SGPM2CLK, except it's not documented in the table in v9 of the datasheet (I hope it will be documented?). If function 1 is the highest priority (which is what all the Aspeed pinctrl drivers assume), then this should be: PIN_DECL_4(K26, GPIOA4, MACLINK1, SCL13, SGPS2CK, SGPM2CLK); Anyway, one of several things could be at fault here: 1. I've made a wrong assumption about the priority order in how I've implemented pinctrl support for Aspeed SoCs 2. The Multi-Function Pin Mapping and Control table is out of date and needs to be fixed (which it already does as it doesn't list SGPM2CLK). 3. The patch needs to align with the assumptions of the Aspeed pinctrl support. I don't think it's 1 as I haven't heard of any issues where we are getting incorrect behaviour because of pinmux. I don't think it's 2 as this patch makes a non-linear change to the ordering. So my hunch is the issue is 3, that the patch is putting the signals in the wrong order. In this case, you want the PIN_DECL_4(...) I outlined above. > FUNC_GROUP_DECL(MACLINK1, K26); > > #define L24 5 > SIG_EXPR_LIST_DECL_SESG(L24, MACLINK2, MACLINK2, SIG_DESC_SET(SCU410, 5)); > SIG_EXPR_LIST_DECL_SESG(L24, SDA13, I2C13, SIG_DESC_SET(SCU4B0, 5)); > -PIN_DECL_2(L24, GPIOA5, MACLINK2, SDA13); > +SIG_EXPR_LIST_DECL_SESG(L24, SGPS2LD, SGPS2, SIG_DESC_SET(SCU690, 5)); > +SIG_EXPR_LIST_DECL_SESG(L24, SGPM2LD, SGPM2, SIG_DESC_SET(SCU6D0, 5)); > +PIN_DECL_4(L24, GPIOA5, SGPM2LD, SGPS2LD, MACLINK2, SDA13); See above. > FUNC_GROUP_DECL(MACLINK2, L24); > > FUNC_GROUP_DECL(I2C13, K26, L24); > @@ -95,16 +101,22 @@ FUNC_GROUP_DECL(I2C13, K26, L24); > #define L23 6 > SIG_EXPR_LIST_DECL_SESG(L23, MACLINK3, MACLINK3, SIG_DESC_SET(SCU410, 6)); > SIG_EXPR_LIST_DECL_SESG(L23, SCL14, I2C14, SIG_DESC_SET(SCU4B0, 6)); > -PIN_DECL_2(L23, GPIOA6, MACLINK3, SCL14); > +SIG_EXPR_LIST_DECL_SESG(L23, SGPS2O, SGPS2, SIG_DESC_SET(SCU690, 6)); > +SIG_EXPR_LIST_DECL_SESG(L23, SGPM2O, SGPM2, SIG_DESC_SET(SCU6D0, 6)); > +PIN_DECL_4(L23, GPIOA6, SGPM2O, SGPS2O, MACLINK3, SCL14); See above. > FUNC_GROUP_DECL(MACLINK3, L23); > > #define K25 7 > SIG_EXPR_LIST_DECL_SESG(K25, MACLINK4, MACLINK4, SIG_DESC_SET(SCU410, 7)); > SIG_EXPR_LIST_DECL_SESG(K25, SDA14, I2C14, SIG_DESC_SET(SCU4B0, 7)); > -PIN_DECL_2(K25, GPIOA7, MACLINK4, SDA14); > +SIG_EXPR_LIST_DECL_SESG(K25, SGPS2I, SGPS2, SIG_DESC_SET(SCU690, 7)); > +SIG_EXPR_LIST_DECL_SESG(K25, SGPM2I, SGPM2, SIG_DESC_SET(SCU6D0, 7)); > +PIN_DECL_4(K25, GPIOA7, SGPM2I, SGPS2I, MACLINK4, SDA14); See above. > FUNC_GROUP_DECL(MACLINK4, K25); > > FUNC_GROUP_DECL(I2C14, L23, K25); > +FUNC_GROUP_DECL(SGPM2, K26, L24, L23, K25); > +FUNC_GROUP_DECL(SGPS2, K26, L24, L23, K25); > > #define J26 8 > SIG_EXPR_LIST_DECL_SESG(J26, SALT1, SALT1, SIG_DESC_SET(SCU410, 8)); > @@ -2060,7 +2072,9 @@ static const struct aspeed_pin_group > aspeed_g6_groups[] = { > ASPEED_PINCTRL_GROUP(EMMCG4), > ASPEED_PINCTRL_GROUP(EMMCG8), > ASPEED_PINCTRL_GROUP(SGPM1), > + ASPEED_PINCTRL_GROUP(SGPM2), > ASPEED_PINCTRL_GROUP(SGPS1), > + ASPEED_PINCTRL_GROUP(SGPS2), > ASPEED_PINCTRL_GROUP(SIOONCTRL), > ASPEED_PINCTRL_GROUP(SIOPBI), > ASPEED_PINCTRL_GROUP(SIOPBO), > @@ -2276,7 +2290,9 @@ static const struct aspeed_pin_function > aspeed_g6_functions[] = { > ASPEED_PINCTRL_FUNC(SD1), > ASPEED_PINCTRL_FUNC(SD2), > ASPEED_PINCTRL_FUNC(SGPM1), > + ASPEED_PINCTRL_FUNC(SGPM2), > ASPEED_PINCTRL_FUNC(SGPS1), > + ASPEED_PINCTRL_FUNC(SGPS2), > ASPEED_PINCTRL_FUNC(SIOONCTRL), > ASPEED_PINCTRL_FUNC(SIOPBI), > ASPEED_PINCTRL_FUNC(SIOPBO), > diff --git a/drivers/pinctrl/aspeed/pinmux-aspeed.h > b/drivers/pinctrl/aspeed/pinmux-aspeed.h > index dba5875ff276..125df796af36 100644 > --- a/drivers/pinctrl/aspeed/pinmux-aspeed.h > +++ b/drivers/pinctrl/aspeed/pinmux-aspeed.h > @@ -730,6 +730,15 @@ struct aspeed_pin_desc { > SIG_EXPR_LIST_PTR(pin, low), \ > SIG_EXPR_LIST_PTR(pin, other)) > > +#define PIN_DECL_4(pin, other, high, medium, low1, low2) \ Bit of a nit pick, but we might as well drop identifying the priorities as high, medium and low given we now have low1 and low2.

AST2600 supports 2 SGPIO master interfaces and 2 SGPIO slave interfaces. Current pinctrl driver only define the first sgpio master and slave interfaces. The sencond SGPIO master and slave interfaces should be added in pinctrl driver as well.
