I think as of now lets have this minimal code for rtc_wakeup.quoted
However, I'm wondering why you are adding DT support as this will always be probed from the MFD driver which pass the platform_data and avoids that allocation.You are right. Originally, it was cleanup patch, - remove pm80x_pdata - Add check for pdata and np - and around rtc_wakeup While doing that I added this nice to have allocation.
Any update/feedback on this? Thanks, Vaibhav
