2015-06-12Doc: serial-rs485.txt: update RS485 driver interfaceBaruch Siach
Since commit a5f276f10ff7 (serial_core: Handle TIOC[GS]RS485 ioctls., 2014-11-06) serial_core handles RS485 ioctls. Drivers only need to implement the rs485_config callback. Update serial-rs485.txt to reflect these changes. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-06-12serial: 8250_pci: Correct uartclk for xr17v35x expansion chipsSoeren Grunewald
The internal clock of the master chip, which is usually 125MHz, is only half (62.5MHz) for the slave chips. So we have to adjust the uartclk for all the slave ports. Therefor we add a new function to determine if a slave chip is present and update pci_xr17v35x_setup accordingly.

The Exar XR17V358 can also be combined with a XR17V354 chip to act as a single 12 port chip. This works the same way as the combining two XR17V358 chips. But the reported device id then is 0x4358.

This would break compilation, since they are are referenced before their definition.

2015-06-12staging: unisys: Don't hold device responses until driver loadsDavid Kershner
Currently if a driver is not loaded for a device, we will not respond to the device create until it is done. This causes s-Par to not mark the partition running if the driver for the device is not loaded. Since there are several devices that could be assigned to a guest that don't have an actual driver this will cause us to never go running. If the device driver is loaded, we WILL continue to only respond to the device PAUSE message when the device driver has responded that it is done with the device.

2015-06-12staging: comedi: das08: clarify sign-magnitude conversionIan Abbott
For DAS08/JR/16 and DAS08/JR/AO-16 boards, the 16-bit analog input readings are assumed to be in a sign-magnitude format and need converting to the COMEDI unsigned sample format. The expressions to do the conversion look a little messy. Use a local variable `magnitude` to make it easier to follow. Also, there seems to be some discrepancy between the manual for these boards and the COMEDI code. The manual implies that 0 is full-scale negative and 65535 is full-scale positive. However, the COMEDI code has used the sign-magnitude conversion for these boards since these two boards were initially supported by a patch from an external contributor to the COMEDI project back in 2001. Assume the code is correct for now, but add a comment to mention the discrepancy.
