* rtc: add rtc-abx80x, a driver for the Abracon AB x80x i2c rtcYing-Chun Liu (PaulLiu)2021-01-271-0/+9
| | | | | | | | | This is a basic driver for the ultra-low-power Abracon AB x80x series of RTC chips. It supports in particular, the supersets AB0805 and AB1805. It allows reading and writing the time, and enables the supercapacitor or battery charger. Signed-off-by: Ying-Chun Liu (PaulLiu) <paul.liu@linaro.org>
* rtc: initialize emulated RTC from environment variableHeinrich Schuchardt2020-10-301-5/+8
| | | | | | | | | | | | | | | | | | | | | | Up to now the emulated RTC is initialized using the U-Boot build time. With this patch the environment variable 'rtc_emul_epoch' can be used to provide a better initial time. The variable is a decimal string with the number of seconds since 1970-01-01. Here is an example where the RTC had not been probed yet: => setenv rtc_emul_epoch 1610109000 => date Date: 2021-01-08 (Friday) Time: 12:30:00 If the variable does not exist, the U-Boot build time is used as fallback. The environment variable may be set when shutting down the operating system if the U-Boot environment is exposed to the OS (cf. ENV_IS_IN_FAT and ENV_IS_IN_EXT4).

* rtc: provide an emulated RTCHeinrich Schuchardt2020-10-271-0/+11
| | | | | | | | | | | On a board without hardware clock this software real time clock can be used. The build time is used to initialize the RTC. So you will have to adjust the time either manually using the 'date' command or use the 'sntp' to update the RTC with the time from a network time server. See CONFIG_CMD_SNTP and CONFIG_BOOTP_NTPSERVER. The RTC time is advanced according to CPU ticks. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* ARM: qemu-arm: enable RTCHeinrich Schuchardt2018-07-191-0/+7
| | | | | | | | | | | | | | | | | QEMU provides an emulated ARM AMBA PrimeCell PL031 RTC. The patch sets the base address in the board include file according to the definition in hw/arm/virt.c of the QEMU source. It defines the Kconfig option for the existing driver, and enables the RTC driver in qemu_arm64_defconfig and qemu_arm_defconfig as well as the date command. We need an RTC to provide the GetTime() runtime service in the UEFI subsystem.
