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 ?
