2009-12-13mfd: ezx-pcap: Don't pass pcap pointer as subdev drvdata.Antonio Ospite
Abusing subdev drvdata is not needed anymore, as all pcap subdevs are now retrieving the pcap pointer from their parent device. This change removes a leftover coming from early versions of ezx-pcap and its subdevs drivers.

2009-09-23spi: prefix modalias with "spi:"Anton Vorontsov
This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

2009-09-17mfd: fix pcap irq bottom handlerDaniel Ribeiro
Mask interrupts before servicing them and loop while pcap asserts the interrupt line. Signed-off-by: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17mfd: add set_ts_bits for pcapDaniel Ribeiro
Some TS controller bits are on the same register as the ADC control, save TS specific bits and export a set_ts_bits function so the TS driver can set it with the adc_mutex lock held. Signed-off-by: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2009-06-17mfd: add PCAP driverDaniel Ribeiro
The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).
