The TSADC gate clock is present only in Exynos4210. It should not be added to exynos4x12.dtsi because the register controlling it is reserved on Exynos4x12. Instead, the Analog to Digital Converter of Exynos4x12 uses PCLK_ADC gate clock from different register. By using proper clock this effectively enables usage of exynos-adc driver on Exynos4412 boards, enables accessing sensors connected to it on Trats2 board (ntc,ncp15wb473 AP and battery thermistors) and fixes following warnings during boot: [ 2.248247] ERROR: could not get clock /adc@126C0000:adc(0) [ 2.248262] exynos-adc 126c0000.adc: failed getting clock, err = -2 [ 2.248293] exynos-adc: probe of 126c0000.adc failed with error -2 Signed-off-by: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx> --- arch/arm/boot/dts/exynos4x12.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/exynos4x12.dtsi b/arch/arm/boot/dts/exynos4x12.dtsi index b77dac61ffb5..d7738dd062b7 100644 --- a/arch/arm/boot/dts/exynos4x12.dtsi +++ b/arch/arm/boot/dts/exynos4x12.dtsi @@ -101,7 +101,7 @@ reg = <0x126C0000 0x100>; interrupt-parent = <&combiner>; interrupts = <10 3>; - clocks = <&clock CLK_TSADC>; + clocks = <&clock CLK_PCLK_ADC>; clock-names = "adc"; #io-channel-cells = <1>; io-channel-ranges; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
