* omap: TWL4030 Bump VMMC1 interface voltage from 3V to 3.15VAsh Charles2011-12-09-2/+2
| | | | | | | | | | | | MMC interfaces are specified to be 3.3V compatible with an operating voltage range of 3.1V to 3.5V for SD cards. This change affects hardware using TWL4030 (TPS6595x) PMICs and should improve the reliability when communicating with marginally-spec'd MMC devices. 3.15V is the highest possible level for this chip. This patch has been tested on a Gumstix Overo board. Signed-off-by: Ash Charles <ash@gumstix.com> Tested-by: Steve Sakoman <steve@sakoman.com>

* ftpmu010: fix relocation and enhance featuresMacpaul Lin2011-04-27-2/+37
| | | | | | | | | | | | | | | | | | | 1. ftpmu010.h: fix and add definitions Enhanced for more features and asm related support according to datasheet. Note: - FTPMU010_PDLLCR0_HCLKOUTDIS is "incorrect" in datasheet. - FTPMU010_PDLLCR0_DLLFRANG is only 1 bit at bit #19. (not 20-19) - FTPMU010_PDLLCR0_HCLKOUTDIS is 4 bits at bit #20. (not 24-21) 2. ftpmu010.c: enhance features and fix relocation - The following functions is added for pmu features. ftpmu010_mfpsr_select_dev() ftpmu010_sdramhtc_set() - This patch also fix the declare statement for relocation.

* 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: OMAP: add convenience function to set TWL4030 regulator voltagesSteve Sakoman2010-09-08-39/+30
| | | | | | | | | | | This patch adds a function to allow one to easily set the target voltage for the TWL4030 regulators. It also modifies the existing code to use this new function. Applicable definitions are moved out of the driver file and into the header file so that they are generally accessible Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* OMAP3 Move twl4030 mmc functionTom Rix2009-07-29-0/+15
| | | | | | | | | | | | | | | | | | | | | | Because twl4030 now has its own device files, move and rename twl4030_mmc_config. twl4030_mmc_config initializes the twl4030 power setting to the mmc device. Because it is in the twl4030 power domain, move it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c. The function was renamed to twl4030_power_mmc_init because all the functions in this file are to have the format twl4030_power_<device>_<action> In this case the suffix is mmc_init so device : mmc action : init 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>
* OMAP3 Move twl4030 power and led functionsTom Rix2009-07-29-1/+54
| | | | | | | | | | | | | | | | | | | | | | | | Because twl4030 now has its own device files, move exiting omap3 power_init_r to a new location. power_init_r is the only function in board/omap3/common. It initializes the twl4030 power for the board and enables the led. The power part of the the function is moved to twl4030_power_init in drivers/power/twl4030.c The power compilation is conditional on the existing config variable CONFIG_TWL4030_POWER. The led part is moved to twl4030_led_init in the new file drivers/misc/twl4030_led.c The led compilation is conditional on the new config variable CONFIG_TWL4030_LED The directory board/omap3/common was removed because power_init_r was the only function in it.

* TWL4030 Add power reset buttonTom Rix2009-07-28-0/+94
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>
