2017-11-20rtc: add support for s35392aNandor Han
Add support for S35392A RTC. The driver supports both U-Boot driver models. Signed-off-by: Nandor Han <nandor.han@ge.com> Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Cc: Heiko Schocher <hs@denx.de>
2017-10-23rtc: mc146818: Correct alarm message for day alarmBin Meng
RTC_CONFIG_D register contains the day within the month to generate an alarm, not the month. This corrects the printf to indicate it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2017-06-16powerpc, 5xxx, 512x: remove support for mpc5xxx and mpc512xHeiko Schocher
There was for long time no activity in the mpx5xxx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in mpc5xxx, so remove it. Signed-off-by: Heiko Schocher <hs@denx.de>
2017-06-12powerpc, 8xx: remove support for 8xxHeiko Schocher
There was for long time no activity in the 8xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 8xx, so remove it (with a heavy heart, knowing that I remove here the root of U-Boot). Signed-off-by: Heiko Schocher <hs@denx.de>
2017-06-09rtc: ds1337: drop "SYS" from config variablesChris Packham
There is some inconsistency between uses of CONFIG_RTC_DS13xx and CONFIG_SYS_RTC_DS13xx. Address this by dropping the "SYS" from these variables. Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

This subsystem has not been converted to driver model, there is only one driver and only one board that uses it. Drop it and its CONFIG option. Also drop the rtc4543 RTC driver since it uses TWS. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2015-05-05dm: rtc: sandbox: Add a driver for the sandbox I2C RTCSimon Glass
Add a driver which communicates with the sandbox I2C emulation RTC device and permits it to be used in U-Boot. This driver is very simple - it just reads and writes selected I2C registers in the device. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-05-05dm: rtc: sandbox: Add an emulated I2C RTC deviceSimon Glass
Add a sandbox I2C emulation device which emulates a real-time clock. The clock works off an offset from the current system time, and supports setting and getting the clock, as well as access to byte-width regisers in the RTC. It does not support changing the system time. This device can be used for testing the 'date' command on sandbox, as well as the RTC uclass. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-05-05dm: rtc: Add a uclass for real-time clocksSimon Glass
Add a uclass for real-time clocks which support getting the current time, setting it and resetting the chip to a known-working state. Some RTCs have additional registers which can be used to store settings, so also provide an interface to these. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-05-05dm: rtc: Rename mktime() and reduce the number of parametersSimon Glass

Rename this function so that it is clear that it is provided by the RTC. Also return an error when it cannot function as expected. This is unlikely to occur since it works for dates since 1752 and many RTCs do not support such old dates. Still it is better to be accurate.

2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
