7config DM_RTC
8	bool "Enable Driver Model for RTC drivers"
9	depends on DM
10	help
11	  Enable drver model for real-time-clock drivers. The RTC uclass
12	  then provides the rtc_get()/rtc_set() interface, delegating to
13	  drivers to perform the actual functions. See rtc.h for a
14	  description of the API.

16config RTC_PCF2127
17	bool "Enable PCF2127 driver"
18	depends on DM_RTC
19	help
20	  The PCF2127 is a CMOS Real Time Clock (RTC) and calendar with an integrated
21	  Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz
22	  crystal optimized for very high accuracy and very low power consumption. The PCF2127
23	  has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a
24	  programmable watchdog function, a timestamp function, and many other features.

28	depends on DM_RTC
29	help
30	  Support for Dallas Semiconductor (now Maxim) DS1307 and DS1338/9 and
31	  compatible Real Time Clock devices.

33config RTC_ISL1208
34	bool "Enable ISL1208 driver"
35	depends on DM_RTC
36	help
37	  The Renesas (formerly Intersil) ISL1208 is a I2C Real Time Clock (RTC) and
38	  calendar with automatic leap year correction, 2-byte battery backed SRAM,
39	  automatic power switch-over, alarm function and 15 selectable frequency
40	  outputs.
41
42	  This driver supports reading and writing the RTC/calendar and detects
43	  total power failures.

52	bool "Enable S35392A driver"
53	select BITREVERSE
54	help
55	  Enable s35392a driver which provides rtc get and set function.
