|
|
* Name: pcf85263_rtc_initialize
|
|
*
|
|
* Description:
|
|
* Initialize the hardware RTC per the selected configuration.
|
|
* This function is called once during the OS initialization sequence by
|
|
* board-specific logic.
|
|
*
|
|
* After pcf85263_rtc_initialize() is called, the OS function
|
|
* clock_synchronize() should also be called to synchronize the system
|
|
* timer to a hardware RTC.
|
|
* That operation is normally performed automatically by the system during
|
|
* clock initialization. However, when an external RTC is used, the board
|
|
* logic will need to explicitly re-synchronize the system timer to the RTC
|
|
* when the RTC becomes available.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) on success; a negated errno on failure
|
|
*
