2017-05-22Drop three-wire serial (TWS) supportSimon Glass
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 <[email protected]> Reviewed-by: Tom Rini <[email protected]>

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 <[email protected]>
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 <[email protected]>
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 <[email protected]>
2015-05-05dm: rtc: Rename mktime() and reduce the number of parametersSimon Glass
Most callers unpack the structure and pass each member. It seems better to pass the whole structure instead, as with the C library. Also add an rtc_ prefix. Signed-off-by: Simon Glass <[email protected]> Acked-by: Heiko Schocher <[email protected]>
2015-05-05dm: rtc: Rename to_tm() to rtc_to_tm() and add error codeSimon 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.

Conflicts: arch/arm/cpu/arm926ejs/mxs/Makefile board/compulab/cm_t35/Makefile board/corscience/tricorder/Makefile board/ppcag/bg0900/Makefile drivers/bootcount/Makefile include/configs/omap4_common.h include/configs/pdnb3.h Makefile conflicts are due to additions/removals of object files on the ARM branch vs KBuild introduction on the main branch. 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

2012-11-14pmic: Extend PMIC framework to support multiple instances of PMIC devicesŁukasz Majewski
The PMIC framework has been extended to support multiple instances of the variety of devices responsible for power management. This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB Interface Circuit). Power related includes have been moved to ./include/power directory. This is a first of a series of patches - in the future "pmic" will be replaced with "power". Two important issues: 1. The PMIC needs to be initialized just after malloc is configured 2. It uses list to hold information about available PMIC devices Signed-off-by: Lukasz Majewski <[email protected]> Signed-off-by: Kyungmin Park <[email protected]> Cc: Stefano Babic <[email protected]>
2012-09-02rtc: pcf8563: Make century compatible with LinuxBenoît Thébaudeau
This driver uses the century bit of this RTC in the opposite way Linux does. From Linux's rtc-pcf8563.c: /* * The meaning of MO_C bit varies by the chip type. * From PCF8563 datasheet: this bit is toggled when the years * register overflows from 99 to 00 * 0 indicates the century is 20xx * 1 indicates the century is 19xx * From RTC8564 datasheet: this bit indicates change of * century. When the year digit data overflows from 99 to 00, * this bit is set. By presetting it to 0 while still in the * 20th century, it will be set in year 2000, ... * There seems no reliable way to know how the system use this * bit. So let's do it heuristically, assuming we are live in * 1970...2069. */ As U-Boot's PCF8563 driver does not say it is supposed to support the RTC8564, make this driver compatible with Linux's by giving the opposite meaning to the century bit.
