From fd595722c1048c021a4c0427afbb807d4a5dbe0b Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 7 Sep 2020 18:11:31 +0200 Subject: ARM: dts: s5pv210: add RTC 32 KHz clock in Torbreck 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/20200907161141.31034-16-krzk@kernel.org --- arch/arm/boot/dts/s5pv210-torbreck.dts | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'arch/arm/boot/dts/s5pv210-torbreck.dts') diff --git a/arch/arm/boot/dts/s5pv210-torbreck.dts b/arch/arm/boot/dts/s5pv210-torbreck.dts index cd25e72ccd84..e18259737684 100644 --- a/arch/arm/boot/dts/s5pv210-torbreck.dts +++ b/arch/arm/boot/dts/s5pv210-torbreck.dts @@ -30,6 +30,13 @@ device_type = "memory"; reg = <0x20000000 0x20000000>; }; + + pmic_ap_clk: clock-0 { + /* Workaround for missing PMIC and its clock */ + compatible = "fixed-clock"; + #clock-cells = <0>; + clock-frequency = <32768>; + }; }; &xusbxti { @@ -54,6 +61,8 @@ &rtc { status = "okay"; + clocks = <&clocks CLK_RTC>, <&pmic_ap_clk>; + clock-names = "rtc", "rtc_src"; }; &sdhci0 { -- cgit v1.2.3
