2013-07-31mfd: Use dev_get_platdata()Jingoo Han
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2012-01-09mfd: Use gpio_request_one from dm355evm_mspAxel Lin
Use gpio_request_one() instead of multiple gpiolib calls. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-10-31mfd: Add module.h to the implicit drivers/mfd usersPaul Gortmaker
With the pending module.h cleanup, these files will fail to compile, unless they explicitly call out the include of this file. [omap-usb-host addition courtesy of Anand Gadiyar <gadiyar@ti.com>] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2009-09-17mfd: Correct ro and cd implemantion on DM355Vipin Bhandari
This patch corrects the support for MMCSD card detection and read only feature for SoC DM355. EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that Bit 2 and 4 should be checked for card detection. However on the EVM, bits 1 and 3 gives this status, for MMC/SD instance 0 and 1 respectively. The pdf also suggests that Bit 1 and 3 should be checked for write protection. However on the EVM bits 2 and 4 gives this status.

2009-06-28Input: dm355evm_keys - fix kconfig symbol namesDavid Brownell
The keypad driver for the DM355 EVM got slightly broken as it merged, since it moved from input/keyboard to input/misc and its Kconfig symbol changed. This patch copes with the changed Kconfig symbol. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-01-04mfd: dm355evm msp430 driverDavid Brownell
Basic MFD framework for the MSP430 microcontroller firmware used on the dm355evm board: - Provides an interface for other drivers: register read/write utilities, and register declarations. - Directly exports: * Many signals through the GPIO framework + LEDs + SW6 through gpio sysfs + NTSC/nPAL jumper through gpio sysfs + ... more could be added later, e.g. MMC signals * Child devices: + LEDs, via leds-gpio child (and default triggers) + RTC, via rtc-dm355evm child device + Buttons and IR control, via dm355evm_keys - Supports power-off system call. Use the reset button to power the board back up; the power supply LED will be on, but the MSP430 waits to re-activate the regulators. - On probe() this: * Announces firmware revision * Turns off the banked LEDs * Exports the resources noted above * Hooks the power-off support * Muxes tvp5146 -or- imager for video input Unless the new tvp514x driver (tracked for mainline) is configured, this assumes that some custom imager driver handles video-in. This completely ignores the registers reporting the output voltages on the various power supplies. Someone could add a hwmon interface if that seems useful.
