2013-10-19staging: comedi: s626: bitfield manipulation macros for CRA, CRB and setupIan Abbott1-41/+212
Some bits of the 'CRB' register have different functions when read or written, so add macros to define the read-only parts. Add macros to define the widths of the bitfields in the 'CRA' and 'CRB' registers and the standard encoder setup value. Add macros to construct and extract parts of the 'CRA' and 'CRB' register values and the standard encoder setup value, along with a couple of general helper macros for the above. Redefine the bitfield mask macros for 'CRA', 'CRB' and standard encoder setup using the above.

There are some bits in the 'CRB' register not defined in "s626.h". Three of these are read-only bits that overlay the write-only interrupt control bits.

The counter 'A' clock polarity field in the 'CRA' register is only 1 bit wide, but the `S626_CRAMSK_CLKPOL_A` macro shows it as 2 bits wide, which would overlap with the counter 'A' interrupt source field. This is harmless as the macro isn't actually used yet, but correct it anyway as I want to use it!

2013-10-19staging: comedi: s626: distinguish counter src from encoder modeIan Abbott2-61/+67
The macros `S626_CLKSRC_COUNTER`, `S626_CLKSRC_TIMER` and `S626_CLKSRC_EXTENDER` are used logically to set the operating mode of an encoder channel. `S626_CLKSRC_COUNTER` (0) is also used as a 2-bit physical value to set the counter source of an encoder channel to "encoder". Rename the macros to `S626_ENCMODE_COUNTER`, `S626_ENCMODE_TIMER` and `S626_ENCMODE_EXTENDER` and rename some other macros and (unused) functions relating to the encoder mode for consistency. Define new macros to specify the physical counter source values for the 'CRA' register and rename the corresponding bitshift and mask macros accordingly. The physical values for the counter source are: S626_CNTSRC_ENCODER = 0 // encoder S626_CNTSRC_DIGIN = 1 // digital inputs S626_CNTSRC_SYSCLK = 2 // system clock up S626_CNTSRC_SYSCLK_DOWN = 3 // system clock down Also use the `S626_CNTSRC_SYSCLK` value as a bitmask (bit 1) to indicate either of the system clock values, with the direction (bit 0) indicated separately in this case.

When setting the clock source for one of the 'A' encoders to operate in "counter" mode in `s626_set_mode_a()`, bitshift the clock source value by `S626_CRABIT_CLKSRC_A` for consistency with the other modes.

2013-10-19staging: comedi: s626: clock polarity and direction are the sameIan Abbott1-4/+0
When setting up an encoder channel, the setup value includes a polarity and direction, but these are the same bit of the setup value: S626_CLKPOL_POS = S626_CNTDIR_UP = 0 S626_CLKPOL_NEG = S626_CNTDIR_DOWN = 1 In the construction of the setup value, both the CLKPOL and the CNTDIR constants are shifted by the same amount `S626_BF_CLKPOL`. Only the following combinations are set up currently (this may change if user configuration of the encoder is implemented properly): (S626_CLKPOL_POS << S626_BF_CLKPOL) (S626_CLKPOL_POS << S626_BF_CLKPOL) | (S626_CNTDIR_UP << S626_BF_CLKPOL) (S626_CLKPOL_POS << S626_BF_CLKPOL) | (S626_CNTDIR_DOWN << S626_BF_CLKPOL) The first two are used in "counter" mode and is equivalent to: (S626_CLKPOL_POS << S626_BF_CLKPOL) The last one is used in "timer" mode and is equivalent to: (S626_CNTDIR_DOWN << S626_BF_CLKPOL) Use the shorter equivalents. The comments in "s626.h" indicate that the 'CLKPOL' constants make more sense for the "counter" mode (when the encoders operate as up/down counters) and the 'CNTDIR' constants make more sense for the "timer" mode.

2013-10-19staging: comedi: rtd520: use normal bitfield functionsIan Abbott1-20/+7
The `unsigned char chan_is_bipolar[]` member of `struct rtd_private` is used with some macros as a packed array of 1-bit values that indicate whether the corresponding entries in the hardware's "channel-gain" table have been set to a bipolar (1) or unipolar (0) range, as the raw samples from the hardware need to be cooked differently in each case. Replace the declaration of the member with a standard Linux bitfield using `DECLARE_BITFIELD()`, and replace the home-grown macros used access the bitfield with the standard Linux non-atomic bitop functions, `__set_bit()`, `__clear_bit()` and `test_bit()`.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Fourth round of IIO new drivers, functionality and cleanups for the 3.13 cycle. New Drivers * cm36651 combined RGB light and proximity sensor. Core improvements * Some more fixes and cleanups related to buffers. These include the second half of a series which went is as fixes. The basis for delaying until the next merge window is that some are too invasive for this late in a cycle and others only effect code paths current unused in the mainline tree. In this case we have: * protecting against concurrent userspace access * fixing a memory leak if a device goes away * avoiding always reallocating the buffer whether or not it has changed (a bug fix, but one with no functional changes other than a small speed improvement.) * Add reference counting for buffers to ensure they hang around if open from userspace or in kernel when the device is forcefully removed. * Return -ENODEV for buffer access operations when the device has gone away. * Add proper locking for iio_update_buffers (currently we only have one buffer per device in mainline, but an input bridge driver is under development which would make this bug 'real'.) * Wake up anyone waiting on a buffer if the device is unregistered. A subsequent read will fail, notifying userspace that the device is no longer there rather than having it wait possibly for ever. * Move the iio_sw_preenable functionality into the core. This avoids drivers having to 'know' about how the buffers are implemented and is called by almost all drivers anyway. Those that don't call it are not harmed by it being called. * New registration approach for information (i.e. sysfs attributes) about events. Much more generic and now similar to how the equivalent is handled for channel information. The events infrastructure had been left behind by other changes so this brings it back in line. * Using the new events registration approach, add a hysterisis event_info element and apply this to those drivers with this property. * A little unitialized variable bug in the generic_buffer.c example. * Factor out the code for freeing lists of IIO Device attributes to avoid some repitition. Driver cleanups * At91 driver gains touch screen support and some related fixes. * Follow up series of patches removing the now redundant iio_sw_buffer_preenable calls. * Lots of conversions to the new event registration methods. * Another round of hmc5843 cleanups as that driver moves towards graduating from staging. * Make some SoC drivers buildable if COMPILE_TEST is used. Follow up fixes for a few bits and bobs that revealed. * Add explicit includes of linux/of.h to those drivers making us of linux/of.h

2013-10-17iio: at91: introduce touch screen support in iio adc driverJosh Wu3-24/+405
AT91 ADC hardware integrate touch screen support. So this patch add touch screen support for at91 adc iio driver. To enable touch screen support in adc, you need to add the dt parameters: 1. which type of touch are used? (4 or 5 wires), sample period time. 2. correct pressure detect threshold value. In the meantime, since touch screen will use a interal period trigger of adc, so it is conflict to other hardware triggers. Driver will disable the hardware trigger support if touch screen is enabled. This driver has been tested in AT91SAM9X5-EK and SAMA5D3x-EK.
