2013-06-18mfd: 88pm800: Enhance sub devices initializationChao Xie
Separate the devices initialization into different functions. It makes the probe function clearer. Signed-off-by: Chao Xie <chao.xie@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-18mfd: 88pm80x: Change chip id definition and detectionChao Xie
Change the chip id definition and detection and then: 1. We no longer need to add PM800_CHIP_XXX for the coming revision. 2. We no longer need to pass driver_data in i2c_device_id as we can distinguish the chips from the CHIP_ID register.

2013-06-18mfd: 88pm800: Enhance error handling for sub pages probe/removeChao Xie
pm800_pages_init and pm800_pages_exit are called by pm800_probe. Change the code to enhance error handling and remove unused code at pm800_pages_init/exit and pm800_probe.

2013-06-18mfd: 88pm800: Remove the power and gpadc page addr from platform dataChao Xie
88pm800 has two addtional pages - power and gpadc. The address of the pages depends on the address of 88pm800. So do not need pass the address of the power and gpadc in platform data. Signed-off-by: Chao Xie <chao.xie@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-18mfd: 88pm800: 88pm805: Remove "IRQF_TRIGGER_FALLING" flagYi Zhang
88pm800/88pm805 interrupt is asserted low if the events happened. So remove IRQF_TRIGGER_FALLING for irq request. Also, the interrupt wiring is board dependent so do not set IRQF_TRIGGER by default.

2013-06-18mfd: 88pm800: Fix NULL pointer dereferenceYi Zhang
Move "device_800_init" to fix NULL pointer error when calling "device_gpadc_init" as it needs "subchip->regmap_gpadc" to set registers via regmap interface Signed-off-by: Yi Zhang <yizhang@marvell.com> Signed-off-by: Chao Xie <chao.xie@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-06-13Merge tag 'am335x_tsc-adc' of git://breakpoint.cc/bigeasy/linuxSamuel Ortiz
A complete refurbished series inclunding: - DT support for the MFD, TSC and ADC driver & platform device support, which has no users, has been killed. - iio_map from last series is gone and replaced by proper nodes in the device tree. - suspend fixes which means correct data structs are taken and no interrupt storm - fifo split which should problem with TSC & ADC beeing used at the same time - The ADC channels are now checked before blindly applied. That means the touch part reads X, Y and Z coordinates and does not mix them up. Same goes for the IIO ADC driver. - The IIO ADC driver now creates files named in_voltageX_raw where X represents the ADC line instead of a number starting at 0. A read from this file can return -EBUSY in case touch is busy and the ADC didn't collect a value.

2013-06-13Merge tag 'mfd-arizona-v3.10-rc2' of ↵Samuel Ortiz
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc mfd: arizona: Updates for v3.10 A bunch of enhancements and fixes for the arizona devices, adding a few new features (the main one being device tree) and improving robustness.
2013-06-12iio: ti_am335x_adc: check if we found the valueSebastian Andrzej Siewior
Usually we get all the values we wanted but it is possible, that te ADC unit is busy performing the conversation for the HW events. In that case -EBUSY is returned and the user may re-call the function. Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
2013-06-12iio: ti_am335x_adc: Allow to specify input lineSebastian Andrzej Siewior
The TSC part allows to specify the input lines. The IIO part assumes that it usues always the last few, that means if IIO has adc-channels set to 2 it will use channel 6 and 7. However it might make sense to use only 6. This patch changes the device property (which was introduced recently and was never in an official release) in a way that the user can specify which of the AIN lines should be used. In Addition to this, the name is now AINx where x is the channel number i.e. for AIN6 we would have 6. Prior this, it always started counting at 0 which is confusing. In addition to this, it also checks for correct step number during reading and does not rely on proper FIFO depth.

2013-06-12input: ti_am335x_tsc: return IRQ_NONE if there was no IRQ for usSebastian Andrzej Siewior
The previous patch ("input/ti_am335x_tsc: ACK the HW_PEN irq in ISR") acked the interrupt so we don't freeze if we don't handle an enabled interrupt source. The interrupt core has a mechanism for this and to get it work one should only say that it handled an interrupt if it is actually the case. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
2013-06-12input: ti_am335x_tsc: ACK the HW_PEN irq in ISRSebastian Andrzej Siewior
The interrupt source IRQENB_HW_PEN is enabled in suspend and suposed to be used as a wake up source. Once this interrupt source is unmaksed, the devices ends up in ISR and never continues. This change ACKs the interrupt and disables it so the system does not freeze. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
2013-06-12input: ti_am335x_adc: use only FIFO0 and clean up a littleSebastian Andrzej Siewior
The driver programs a threshold of "coordinate_readouts" say 5. The REG_FIFO0THR registers says it should it be programmed to "threshold minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2. Multiplied by two because 5 for X and 5 for Y and plus 2 because we have two Z. The whole thing kind of works because It reads the 5 coordinates for X and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored within the loop and read later. Nothing guaranties that FIFO1 is ready by the time it is read. In fact I could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for Y channel 7 for Z. The problem is that channel 7 and channel 12 got somehow mixed up. The other Problem is that FIFO1 is also used by the IIO part leading to wrong results if both (tsc & adc) are used. The patch tries to clean up the whole thing a little: - Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter part in the for loop. This is just confusing. - Use only FIFO0 in TSC. The fifo has space for 64 entries so should be fine. - Read the whole FIFO in one function and check the channel. - in case we dawdle around, make sure we only read a multiple of our coordinate set. On the second interrupt we will cleanup the remaining enties. Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
2013-06-12mfd: iio: ti_am335x_adc: rename device from tiadc to TI-am335x-adcSebastian Andrzej Siewior

2013-06-12mfd: input: ti_am335x_tsc: rename device from tsc to TI-am335x-tscSebastian Andrzej Siewior
