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 --- arch/arm/boot/dts/s5pv210-smdkc110.dts | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/arch/arm/boot/dts/s5pv210-smdkc110.dts b/arch/arm/boot/dts/s5pv210-smdkc110.dts index e5aec6c526fb..0c623b78af72 100644 --- a/arch/arm/boot/dts/s5pv210-smdkc110.dts +++ b/arch/arm/boot/dts/s5pv210-smdkc110.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"; }; &i2c0 {
