2 # RTC drivers configuration
8 bool "Enable Driver Model for RTC drivers"
12 Enable drver model for real-time-clock drivers. The RTC uclass
13 then provides the rtc_get()/rtc_set() interface, delegating to
14 drivers to perform the actual functions. See rtc.h for a
15 description of the API.
18 bool "Enable Driver Model for RTC drivers in SPL"
21 Enable drver model for real-time-clock drivers. The RTC uclass
22 then provides the rtc_get()/rtc_set() interface, delegating to
23 drivers to perform the actual functions. See rtc.h for a
24 description of the API.
27 bool "Enable Driver Model for RTC drivers in TPL"
30 Enable drver model for real-time-clock drivers. The RTC uclass
31 then provides the rtc_get()/rtc_set() interface, delegating to
32 drivers to perform the actual functions. See rtc.h for a
33 description of the API.
