2015-08-12input: twl4030: Keypad scan and inputPaul Kocialkowski
This allows scanning the twl4030 keypad, storing the result in a 64-byte long matrix with the twl4030_keypad_scan function. Detecting a key at a given column and row is made easier with the twl4030_keypad_key function. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-by: Tom Rini <trini@konsulko.com>
2015-08-12input: TWL4030 input support for power button, USB and chargerPaul Kocialkowski
This adds support for detecting a few inputs exported by the TWL4030. Currently-supported inputs are the power button, USB and charger presence. Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2015-08-12power: twl4030: Power off supportPaul Kocialkowski
This adds support for powering off (the omap3 SoC) from the twl4030. This is especially useful when the kernel does not actually power off the device using this method but reboots and leaves it up to the bootloader to actually turn the power off.

2014-12-04twl4030: device-index-specific MMC power initializations, common ramp-up delayPaul Kocialkowski
Not every device has multiple MMC slots available, so it makes sense to enable only the required LDOs for the available slots. Generic code in omap_hsmmc will enable both VMMC1 and VMMC2, in doubt. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-by: Tom Rini <trini@ti.com>

2014-10-31twl4030: VMMC2 3.2V enable on MMC initPaul Kocialkowski
This enables the VMMC2 LDO, which powers the MMC2 device. When the device starts from MMC2, this has already been enabled by the BootROM, but when starting from peripheral boot (USB, UART), it is not the case.

2011-12-09omap: TWL4030 Bump VMMC1 interface voltage from 3V to 3.15VAsh Charles
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>
2010-09-08ARMV7: OMAP: add convenience function to set TWL4030 regulator voltagesSteve Sakoman
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>
2010-01-04TWL4030: make LEDs selectable for twl4030_led_init()Grazvydas Ignotas
Not all boards have both LEDs hooked, so enabling both on boards with single LED will just waste power. Make it possible to choose LEDs by adding argument to twl4030_led_init(). Using this turn on only LEDB for pandora, leave both LEDs on for all other boards, as it was before this patch. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com>
2009-12-20TWL4030 Add usb PHY supportTom Rix
The twl4030 provides a PHY device for connecting a link device, like musb, to physical connection. This change adds the twl4030 usb registers and functions for initializing the PHY as required by omap3. Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
2009-07-29OMAP3 Move twl4030 mmc functionTom Rix
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>
2009-07-29OMAP3 Move twl4030 power and led functionsTom Rix
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.

2009-07-28TWL4030 Add power reset buttonTom Rix
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>
