The datasheet also describes the wires as SCIFA. So, to make use of the bigger FIFOs switch to SCIFA instead. Signed-off-by: Wolfram Sang --- Currently, I use this patch to check if the DMA RX issue is the same on SCIF and SCIFA (yes, it is). However, I still think it makes sense to use the bigger FIFOs. I will check this next week with Bastian's FIFO patches. Until then, I send this as RFC to collect opinions speaking for/against this change. arch/arm/boot/dts/r8a7790-lager.dts | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) diff --git a/arch/arm/boot/dts/r8a7790-lager.dts b/arch/arm/boot/dts/r8a7790-lager.dts index 84dcafa7179b..782f0aa938b3 100644 --- a/arch/arm/boot/dts/r8a7790-lager.dts +++ b/arch/arm/boot/dts/r8a7790-lager.dts @@ -19,8 +19,8 @@ compatible = "renesas,lager", "renesas,r8a7790"; aliases { - serial6 = &scif0; - serial7 = &scif1; + serial6 = &scifa0; + serial7 = &scifa1; }; chosen { @@ -159,9 +159,9 @@ renesas,function = "du"; }; - scif0_pins: serial0 { - renesas,groups = "scif0_data"; - renesas,function = "scif0"; + scifa0_pins: serial0 { + renesas,groups = "scifa0_data"; + renesas,function = "scifa0"; }; ether_pins: ether { @@ -174,9 +174,9 @@ renesas,function = "intc"; }; - scif1_pins: serial1 { - renesas,groups = "scif1_data"; - renesas,function = "scif1"; + scifa1_pins: serial1 { + renesas,groups = "scifa1_data"; + renesas,function = "scifa1"; }; sdhi0_pins: sd0 { @@ -308,15 +308,15 @@ }; }; -&scif0 { - pinctrl-0 = <&scif0_pins>; +&scifa0 { + pinctrl-0 = <&scifa0_pins>; pinctrl-names = "default"; status = "okay"; }; -&scif1 { - pinctrl-0 = <&scif1_pins>; +&scifa1 { + pinctrl-0 = <&scifa1_pins>; pinctrl-names = "default"; status = "okay"; -- 2.0.0
