[PULL 17/17] linux-user: Add support for read/clear RTC voltage low detector using ioctls |
Date: |
Thu, 23 Jan 2020 09:22:27 +0100 |
From: Filip Bozuta <address@hidden>
This patch implements functionalities of following ioctls:
RTC_VL_READ - Read voltage low detection information
Read the voltage low for RTCs that support voltage low.
The third ioctl's' argument points to an int in which
the voltage low is returned.
RTC_VL_CLR - Clear voltage low information
Clear the information about voltage low for RTCs that
support voltage low. The third ioctl(2) argument is
ignored.
Implementation notes:
Since one ioctl has a pointer to 'int' as its third agrument,
and another ioctl has NULL as its third argument, their
implementation was straightforward.
