* ARM: pxa: remove irq_to_gpio from ezx-pcap driverArnd Bergmann2012-08-091-0/+1
| | | | | | | | | | | | | | | | | | | | The irq_to_gpio function was removed from the pxa platform in linux-3.2, and this driver has been broken since. There is actually no in-tree user of this driver that adds this platform device, but the driver can and does get enabled on some platforms. Without this patch, building ezx_defconfig results in: drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work': drivers/mfd/ezx-pcap.c:205:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Haojian Zhuang <haojian.zhuang@gmail.com> Cc: stable@vger.kernel.org (v3.2+) Cc: Samuel Ortiz <sameo@linux.intel.com> Cc: Daniel Ribeiro <drwyrm@gmail.com>
* mfd: Remove ezx-pcap defines for custom led gpio encodingAntonio Ospite2009-12-131-3/+0
| | | | | | | | | | | We used these, in a first version of leds-pcap driver, in order to encode gpio enabling and gpio inversion for a led inside the variable used for the gpio number. In the new leds-pcap driver we rely on gpio_is_valid() to derive if a led is gpio enabled and we have a dedicated flag to tell if the gpio value has to be inverted.

* mfd: Remove VIB defines from pcap header fileDaniel Ribeiro2009-09-171-4/+0
| | | | | | | | Vibrator will be accessed via the pcap-regulator driver, no need to expose its bits in the header file. Signed-off-by: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: add ezx_pcap_setbitsDaniel Ribeiro2009-09-171-0/+1
| | | | | | | | Provides an atomic set_bits functions, as needed by the pcap-regulator driver. Signed-off-by: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: add set_ts_bits for pcapDaniel Ribeiro2009-09-171-0/+1
| | | | | | | | | 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.

* mfd: add PCAP driverDaniel Ribeiro2009-06-171-0/+256
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).
