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>

The user needs to take care not to exceed the count more than 16. While using ADC and TSC one should take care to set this parameter correctly.

2013-06-12mfd: input: iio: ti_am335x_adc: use one structure for ti_tscadc_devSebastian Andrzej Siewior
The mfd driver creates platform data for the child devices and it is the ti_tscadc_dev struct. This struct is copied for the two devices. The copy of the structure makes a common lock in this structure a little less usefull. Therefore the platform data is not a pointer to the structure and the same structure is used. While doing the change I noticed that the suspend/resume code assumes the wrong pointer for ti_tscadc_dev and this has been fixed as well.
