* mfd: ab8500-debugfs: Remove use of seq_printf return valueJoe Perches2015-03-12
| | | | | | | | | | | The seq_printf return value, because it's frequently misused, will eventually be converted to void. See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to seq_has_overflowed() and make public") Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: rt5033: MFD_RT5033 needs to select REGMAP_IRQArtem Savkov2015-03-12
| | | | | | | | | | | | Since commit 0b2712585(linux-next.git) this driver uses regmap_irq and so needs to select REGMAP_IRQ. This fixes the following compilation errors: ERROR: "regmap_irq_get_domain" [drivers/mfd/rt5033.ko] undefined! ERROR: "regmap_add_irq_chip" [drivers/mfd/rt5033.ko] undefined!

| | | | | | | | | | The range of registers used by this driver exceeds that available via SPI with no paging (127), so we have to override the values from the default config which is set-up for I2C access.

* mfd: ti_am335x_tscadc: Remove unwanted reg_se_cache saveVignesh R2015-03-03
| | | | | | | | | | | | | | | In one shot mode, sequencer automatically disables all enabled steps at the end of each cycle. (both ADC steps and TSC steps) Hence these steps need not be saved in reg_se_cache for clearing these steps at a later stage. Also, when ADC wakes up Sequencer should not be busy executing any of the config steps except for the charge step. Previously charge step was 1 ADC clock cycle and hence it was ignored. TSC steps are always disabled at the end of each conversion cycle, hence there is no need to explicitly disable TSC steps by writing 0 to REG_SE.

Under current 1-HZ polling interval setting in mmc_core, the worst case of such undetectablility is about 1 second. To further reduce the undetectability, detect card slot again in suspend method and defer the autosuspend if the slot is loaded. The default 2 second autosuspend delay of USB subsystem should let the next polling detects the card.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is used only on Exynos based boards with DTS support. After removal of board file support from max77686 and max77802 regulator drivers, the MFD driver can be converted to DTS-only version. This simplifies a little the code: 1. No dead (unused) entries in platform_data structure. 2. More code removed. 3. Regulator driver does not depend on allocated memory from MFD driver. 4. It makes also easier extending the regulator driver. Add to the max77686 MFD driver dependency on CONFIG_OF because without DTS the regulator drivers (max77686 and max77802) won't bind.

| * mfd: dln2: Add suspend/resume functionalityOctavian Purdila2015-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without suspend/resume functionality in the USB driver the USB core will disconnect and reconnect the DLN2 port and because the GPIO framework does not yet support removal of an in-use controller a suspend/resume operation will result in a crash. This patch provides suspend and resume functions for the DLN2 driver so that the above scenario is avoided, if the host controller does not drop VBUS during suspend, since in this case the device state is preserved. We chose not implemented reset_resume so that if the host controller does drop VBUS the resume path will go through above the disconnect/reconnect process since it is probably better to fix the GPIO framework disconnect issue then to save and restore the device state for every driver.
