Provide an implementation of the callback rtc_class_ops.alarm_irq_enable for rtc-opal driver. This callback is called when the wake alarm is disabled via the command: 'echo 0 > /sys/class/rtc/rtc0/wakealarm' Without this the Timed-Power-On(TPO) config remains set even when its disabled by the above command and FSP will still force machine boot at previously configured alarm time. The callback is implemented as function opal_tpo_alarm_irq_enable() which calls opal_set_tpo_time() with alarm.enabled == 0. A branch is added to opal_set_tpo_time() to handle this case by passing y_m_d == h_m_s_ms == 0 to opal as arguments for opal_tpo_write() call.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
