If anyone has any objections, please let me know. ------------------ From: Krzysztof Kozlowski [ Upstream commit 7260b363457a22b8723d5cbc43fee67397896d07 ] The S3C RTC requires 32768 Hz clock as input which is provided by PMIC. However the PMIC is not described in DTS at all so at least add a workaround to model its clock with a fixed-clock. This fixes dtbs_check warnings: rtc@e2800000: clocks: [[2, 145]] is too short rtc@e2800000: clock-names: ['rtc'] is too short Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20200907161141.31034-15-krzk@kernel.org Stable-dep-of: 982655cb0e7f ("ARM: dts: samsung: s5pv210-smdkv210: correct ethernet reg addresses (split)") Signed-off-by: Sasha Levin --- arch/arm/boot/dts/s5pv210-smdkv210.dts | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/arch/arm/boot/dts/s5pv210-smdkv210.dts b/arch/arm/boot/dts/s5pv210-smdkv210.dts index 84b38f1851991..1f20622da7194 100644 --- a/arch/arm/boot/dts/s5pv210-smdkv210.dts +++ b/arch/arm/boot/dts/s5pv210-smdkv210.dts @@ -31,6 +31,13 @@ memory@20000000 { reg = <0x20000000 0x40000000>; }; + pmic_ap_clk: clock-0 { + /* Workaround for missing PMIC and its clock */ + compatible = "fixed-clock"; + #clock-cells = <0>; + clock-frequency = <32768>; + }; + ethernet@18000000 { compatible = "davicom,dm9000"; reg = <0xA8000000 0x2 0xA8000002 0x2>; @@ -147,6 +154,8 @@ &uart3 { &rtc { status = "okay"; + clocks = <&clocks CLK_RTC>, <&pmic_ap_clk>; + clock-names = "rtc", "rtc_src"; }; &sdhci0 { -- 2.40.1
