Bug#782364: linux-image-3.16.0-4-armmp: please configure drivers for both Cubox i4pro real time clocks
Package: src:linux
Version: 3.16.7-ckt7-1
Severity: wishlist
Tags: newcomer
Whenever I reset my cubox-i4Pro by disconnecting the power plug, the hardware real-time-clock gets
reset to midnight UTC, Dec 31, 1970.
Even though the SolidRun literature says that the i4Pro has a battery backed RTC.
A bit of googling reveals that this is related to the following fact (Quoted from the SolidRun forums)
>There are two RTC inside CuBox-i
>1. One connected to the SNVS rail (internal i.MX6) which is not battery backed and typically goes to /dev/rtc0
>2. Second is NXP PFC8523 based and that one has battery backup (/dev/rtc1)

Curiously, when I look at the Debian Jessie system running on the box, I find that there is only one /dev/rtc* device,
and that seems to be associated with the SNVS clock. The PFC8523 clock is not availableâ?¦
Checking /boot/config-3.16.0-4-armmp, I see what I think is an explanation, because
# CONFIG_RTC_DRV_PCF8523 is not set
and
CONFIG_RTC_DRV_SNVS=y
Other Linux systems (e.g. Arch) appear (according to the above mentioned googling) to have their kernel compiled so as to
provide both /dev/rtc0 attached to the SNVS clock, and /dev/rtc1 attached to the PFC8523 clock.
Would it be possible to configure the default Debian Jessie kernel to do the same?
Ideally, the PFC8523 clock should show up as /dev/rtc0, linked to /dev/rtc,
so that the battery backed clock is used by default to set the system clock at boot-time.
Failing that, it may be possible to address this by setting HCTOSYS_DEVICE in /etc/default/hwclock appropriately.
Or maybe one could tweak a rule in /etc/udev ?
Karsten Merker commented via email:
Yes, that should just need enabling the appropriate module.
The device-tree instantiates the pcf8523 clock chip:
&i2c3 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_cubox_i_i2c3>;
status = "okay";
rtc: pcf8523@68 {
compatible = "nxp,pcf8523";
reg = <0x68>;
};
};
So if the module is available, it should be loaded automatically.
Please file a wishlist bug against "Source: linux, Version:
3.16.7-ckt9-1" so that the kernel maintainers can enable the
module for the next kernel upload.
