2015-10-27staging: comedi: fix extreme case of comedi_nsamples_left()Ian Abbott
`comedi_nsamples_left(s, nsamples)` returns the number of samples remaining to complete an asynchronous command or the passed in `nsamples`, whichever is lower. However, it goes wrong in the extreme case of setting the `nsamples` parameter to `UINT_MAX` when the number of conversions per "scan" (`s->async->cmd.scan_end_arg`) is 1. It uses `comedi_nscans_remaining(s, nscans)` to determine the number of scans remaining, or the parameter `nscans`, whichever is lower. To determine the parameter `nscans`, it divides `nsamples` by the number of conversions per scan and adds 1. The addition of 1 is to avoid setting the parameter `nscans` to 0, as `comedi_nscans_remaining(s, nscans)` treats that value specially. However in the extreme case where `nsamples` is `UINT_MAX` and the number of samples per scan is 1, the addition of 1 to `nscans` overflows, producing the unwanted 0. Fix it by refactoring new a function `__comedi_nscans_remaining(s, nscans)` out of `comedi_nscans_remaining(s, nscans)`. The new function does everything except the special handling when `nscans` is 0. Change `comedi_nsamples_remaining()` to call the new function without adding 1 to `nscans` to avoid the overflow. This overflow bug doesn't affect any of the current COMEDI drivers. I stumbled across it while changing to one of the drivers.

mt8173 IC spi HW has 4 gpio group, it's possible to support max <= 4 slave devices, even mtk spi HW is not congruent to spi core. 1. When a device do a spi_message transfer, spi HW should know which pad-group this device is on, and then writes pad-select register. 2. Mtk pad-select register just selects which MISO pin HW will receive data. For example, pad-select=1(select spi1 pins), HW just receives data from spi1 MISO, but it still send waveform to all 4 group cs/clk/mosi. If cs pin in other groups is still spi mode, after spi1 is selected(by active cs pin), devices on other group will also be selected.

Add support for proprietary commands useful mainly for factory testings. Here is a list: - FACTORY_MODE: Allow to set the driver into a mode where no secure element are activated. It does not consider any NFC_ATTR_VENDOR_DATA. - HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes command. It does not consider any NFC_ATTR_VENDOR_DATA. - HCI_DM_PUT_DATA: Allow to configure specific CLF registry as for example RF trimmings or low level drivers configurations (I2C, SPI, SWP). - HCI_DM_UPDATE_AID: Allow to configure an AID routing into the CLF routing table following RF technology, CLF mode or protocol. - HCI_DM_GET_INFO: Allow to retrieve CLF information. - HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as low level drivers configurations or RF trimmings. - HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete packet can be more than 8KB. - HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF configuration changes without CLF power off. - HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example the white list). - HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF technology. When using this command to anti-collision is done. - HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF connectivity.

2015-10-27NFC: st-nci: Disable irq when powering the device upChristophe Ricard
Upon some conditions (timing, CLF errors, platform errors...), the irq might be already active when powering the device. Add irq_active variable as a guard to avoid kernel warning message Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2015-10-27NFC: st21nfca: Add error messages for unexpected HCI eventsChristophe Ricard
Potentially an unexpected HCI event may occur because of a firmware bug. It could be transparent for the user but we should at least log it. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2015-10-27NFC: netlink: Add mode parameter to deactivate_target functionsChristophe Ricard
In order to manage in a better way the nci poll mode state machine, add mode parameter to deactivate_target functions. This way we can manage different target state. mode parameter make sense only in nci core.
