H Hartley Sweeten authored
Currently the analog output subdevice has two support functions: (*insn_config) - i_APCI3501_ConfigAnalogOutput() (*insn_write) - i_APCI3501_WriteAnalogOutput() The (*insn_config) function is used to configure the analog outputs in either bipolar or unipolar mode. This function abuses the comedi API since it treats the data[0] value as a parameter instead of as the config "instruction". The (*insn_write) function then writes a single value to the desired analog output channel after doing some sanity checking on the channel number. The sanity checking is not required since the comedi core has already done it. Also, the (*insn_write) functions are supposed to write all the data, indicated by insn->n, to the channel not just a single value. Rewrite the support code so it works properly with the comedi API. The bipolar/unipolar configuration can be determine in the (*insn_write) by checking the passed insn->chanspec. Since the unipolar configuration only has 13-bit resolution, we need to check that the data is in range because the subdevice 'maxdata' is set to 14-bits for the bipolar mode. If the data is out of range, output a dev_warn() and return -EINVAL.

Rename the CamelCase local variables. Refactor the code a bit to remove the need for some of the local variables. Add a couple defines to the register map to help make the code more concise.

Refactor the code that waits for the DAC to be ready into a helper function. A timeout of some sort should be added to this helper so code the users to expect the error condition. In i_APCI3501_WriteAnalogOutput() just return the error and don't actually write the new value to the DAC. In apci3501_reset() output a dev_warn() that the DAC was not ready.

The analog outputs of this board are always 14-bit. Remove this information from the boardinfo and just set the 'maxdata' directly in the subdevice init. Initialize with a hex value as that is more standard in the comedi drivers. Since devpriv->s_EeParameters.i_AoMaxdata is not longer being used, don't bother initializing it.

The board supported by this driver has an eeprom connected to an AMCC S5933 PCI controller chip. Knowing this, we can simplify the code that reads the PCI bars to get the iobase addresses used in the driver. Also, since the dw_AiBase is not ioremap'ed, we can remove the iounmap in the detach.

This driver needs to read the on-board eeprom to determine the number of analog output channels (4 or 8) on the board. But, sinde we know the board has an eeprom and the PCI controller chip is an AMCC S5933, we can simplify the code and remove the code that sets the extra wait state neede for the AMCC S5920.

The board supported by this driver has 2 digital input. Remove the conditional and always init the subdevice.

The SDF_GROUND and SDF_COMMON flags only have meaning for analog subdevices. Remove the len_chanlist initialization, it only has meaning for subdevices that support commands. Remove the io_bits initialization, it only has meaning for digital i/o subdevices that have configurable outputs.

This driver is for a simple analog output board with 4 or 8, 14-bit outputs. The board also has 4 digital i/o channels (2 out/2 in) as well as a watchdog or timer. Using the addi-data "common" code in this driver introduces a lot of bloat. Copy the code in addi_common.c to this driver and remove the #include that caused it to be compiled with the driver. This will allow removing the bloat. Rename the auto_attach and detach functions so they have namespace associated with this driver.

A QEMU pipe is a very fast communication channel between the guest system and the emulator. Usage from the guest is simply something like; // connect to special device fd = open("/dev/qemu_pipe", O_RDWR); // tell which service we want to talk to (must be zero-terminated) write(fd, "pipeName", strlen("pipeName")+1); // do read()/write() through fd now ... // close channel close(fd); Signed-off-by: David 'Digit' Turner <digit@android.com> [Added support for parameter buffers for speed] igned-off-by: Xin, Xiaohui <xiaohui.xin@intel.com> Signed-off-by: Jiang, Yunhong <yunhong.jiang@intel.com> Signed-off-by: Nakajima, Jun <jun.nakajima@intel.com> [Ported to 3.6] Signed-off-by: Tom Keel <thomas.keel@intel.com> [Ported to 3.7, moved to platform/goldfish] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
