Hey, I've got a Porter board (Revision B) which stopped showing serial output since the patch mentioned in the subject. The terrible clearly wrong hack below gets serial back (reverting to just the fck clock for scif0) on both linux-next and linux master. Unfortunately I don't have enough documentation on the board/hardware to diagnose this further, but hopefully someone else does ;) -- Sjoerd Simons Collabora Ltd. --- diff --git a/arch/arm/boot/dts/r8a7791.dtsi b/arch/arm/boot/dts/r8a7791.dtsi index 8693888..b2c1f1c 100644 --- a/arch/arm/boot/dts/r8a7791.dtsi +++ b/arch/arm/boot/dts/r8a7791.dtsi @@ -731,9 +731,8 @@ "renesas,scif"; reg = <0 0xe6e60000 0 64>; interrupts = <GIC_SPI 152 IRQ_TYPE_LEVEL_HIGH>; - clocks = <&mstp7_clks R8A7791_CLK_SCIF0>, <&zs_clk>, - <&scif_clk>; - clock-names = "fck", "brg_int", "scif_clk"; + clocks = <&mstp7_clks R8A7791_CLK_SCIF0>; + clock-names = "fck"; dmas = <&dmac0 0x29>, <&dmac0 0x2a>, <&dmac1 0x29>, <&dmac1 0x2a>; dma-names = "tx", "rx", "tx", "rx";
