Hello, I am trying to set RTC on Nexus 5 (which uses qpnp-rtc driver).and getting a permission error while setting it.
I am making following call from my application with valid arguments : ioctl(rtc_fd, RTC_SET_TIME, tod) when I make this call I see below messages in dmesg logs : [ 26.945670] spmi_pmic_arb fc4cf000.qcom,spmi: pmic_arb_wait_for_done: transaction denied (0x5) [ 26.945743] qcom,qpnp-rtc qpnp-rtc-f85bbe00: SPMI write failed [ 26.945856] qcom,qpnp-rtc qpnp-rtc-f85bbe00: Write to RTC reg failed 1 The transaction denied message is coming from https://github.com/CyanogenMod/android_kernel_lge_hammerhead/blob/85564c374b6b082fc447f6dae53a630c04b4ef1c/drivers/spmi/spmi-pmic-arb.c#L158 It's fairly low level stuff and I am not sure why should it give a permission error. The only config option I can find from documentation is qpnp-rtc-write (https://github.com/CyanogenMod/android_kernel_lge_hammerhead/blob/cm-11.0/Documentation/devicetree/bindings/rtc/qpnp-rtc.txt) and it is set in my configurations. In what cases I will get this error while setting RTC ? Could this be a bug in the driver ? -- Regards, Siteshwar -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
