Subject: add possibility of disabling rk808-rtc
|
|
|
|
To disable rk808-rtc driver from loading for specific board
|
|
add the following stanza to rk808 node in device tree:
|
|
|
|
rtc {
|
|
compatible = "rk808-rtc";
|
|
status = "disabled";
|
|
}
|
|
|
|
This is needed for roc-rk3399-pc plus (a.k.a. Station P1).
|
|
Without the change rk808's rtc is initialised and used for time keeping
|
|
although there is another rtc (hym8563) that should be actually used.
