From b2194d7dfc95a404990da73ebd394f6f6946a4a0 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Tue, 16 May 2023 22:30:29 +0200 Subject: ARM: dts: meson8: correct uart_B and uart_C clock references [ Upstream commit 98b503c7fb13a17a47d8ebf15fa8f7c10118e75c ] On Meson8 uart_B and uart_C do not work, because they are relying on incorrect clocks. Change the references of pclk to the correct CLKID (UART1 for uart_B and UART2 for uart_C), to allow use of the two uarts. This was originally reported by Hans-Frieder Vogt for Meson8b [0], but the same bug is also present in meson8.dtsi [0] https://lore.kernel.org/linux-amlogic/trinity-bf20bcb9-790b-4ab9-99e3-0831ef8257f4-1680878185420@3c-app-gmx-bap55/ Fixes: 57007bfb5469 ("ARM: dts: meson8: Fix the UART device-tree schema validation") Reported-by: Hans-Frieder Vogt # for meson8b.dtsi Signed-off-by: Martin Blumenstingl Link: https://lore.kernel.org/r/20230516203029.1031174-1-martin.blumenstingl@googlemail.com Signed-off-by: Neil Armstrong Signed-off-by: Sasha Levin --- arch/arm/boot/dts/meson8.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/arm') diff --git a/arch/arm/boot/dts/meson8.dtsi b/arch/arm/boot/dts/meson8.dtsi index 0f8bac8bac8b..f9da7faa2186 100644 --- a/arch/arm/boot/dts/meson8.dtsi +++ b/arch/arm/boot/dts/meson8.dtsi @@ -749,13 +749,13 @@ &uart_B { compatible = "amlogic,meson8-uart"; - clocks = <&xtal>, <&clkc CLKID_UART0>, <&clkc CLKID_CLK81>; + clocks = <&xtal>, <&clkc CLKID_UART1>, <&clkc CLKID_CLK81>; clock-names = "xtal", "pclk", "baud"; }; &uart_C { compatible = "amlogic,meson8-uart"; - clocks = <&xtal>, <&clkc CLKID_UART0>, <&clkc CLKID_CLK81>; + clocks = <&xtal>, <&clkc CLKID_UART2>, <&clkc CLKID_CLK81>; clock-names = "xtal", "pclk", "baud"; }; -- cgit 1.4.1
