This is a initial version so it's very similar with syscon
reboot mode driver. We will add more functionalities in the
further after dependency is ready.

+Qualcomm Reboot Mode Driver
+
+Qualcomm reboot mode driver based on reboot mode framework to update
+SPMI specific bits.
+
+Required Properties:
+-compatible: "qcom,reboot-mode"
+-offset: offset of the SPMI reboot mode register
+
+Optional Properties:
+-mask: mask of reboot mode
+-mode-xxx: magic of reboot mode
+
+Example:
+ qcom,reboot-mode@88f {
+ compatible = "qcom,reboot-mode";
+ offset = <0x88f>;
+ mode-normal = <0x00>;
+ mode-recovery = <0x04>;
+ mode-bootloader = <0x08>;
+ mode-rtc = <0x0C>;
So I don't think we've had a "rtc" mode before. This needs to be very
clearly documented (or maybe just skipped) so we don't start fraying
with all the various vendor specific modes.
Thanks for the comments, I will skip this specific mode in next version
of this patch.
thanks
