* i2c: Add TPS6586X driverSimon Glass2012-05-15-0/+1
| | | | | | | | | This power management chip supports battery charging and a large number of power supplies. This initial driver only provides the ability to adjust the two synchronous buck converters SM0 and SM1 in a stepwise manner.

* power: twl6035: add palmas PMIC supportSRICHARAN R2012-05-15-0/+1
| | | | | | palmas/TWL6035 is power IC for omap5 evm boards Signed-off-by: Balaji T K <balajitk@ti.com>
* ftpmu010: support faraday ftpmu010 driverMacpaul Lin2011-01-25-0/+1
| | | | | | | | | Faraday's ftpmu010 is a power managemnet unit which support cpu sleep and frequency scaling. It has been integrated into many SoC. This patch also move ftpmu010 to a proper place for later enhancement. Signed-off-by: Macpaul Lin <macpaul@andestech.com>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* ARMV7: Add support for the TWL6030 I2C power chip used in OMAP4 systemsSteve Sakoman2010-08-05-0/+1
| | | | | | | | This patch add the basic infrastructure for the TWL6030 driver and enables support in the two existing OMAP4 boards, Panda and OMAP4430 SDP Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* TWL4030 Add power reset buttonTom Rix2009-07-28-0/+47
The Zoom2 power reset button is on the top right side of the main board. Press and hold for about to 8 seconds to completely reset the board. Some of the beta boards have a hardware problem that prevents using this feature. If is difficult to further characterize the boards that fail. So disable resetting for all beta boards. The Zoom1 reset button is the red circle on the top right, front of the board. Press and hold the button for 8 seconds to completely reset the board. After analyzing beagle, it was determined that other boards that use the twl4030 for power managment can also make use this function. The resetting is done by the power management part of the twl4030. Since there is no existing drivers/power, add one. The compilation of power/twl4030.h is controlled by the config variable CONFIG_TWL4030_POWER Signed-off-by: Tom Rix <Tom.Rix@windriver.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Heiko Schocher <hs@denx.de>
