2017-06-22NFC: st-nci: Get rid of code duplication in ->probe()Andy Shevchenko
Since OF and ACPI case almost the same get rid of code duplication by moving gpiod_get() calls directly to ->probe(). Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2017-06-22NFC: st-nci: Add GPIO ACPI mapping tableAndy Shevchenko
In order to make GPIO ACPI library stricter prepare users of gpiod_get_index() to correctly behave when there no mapping is provided by firmware. Here we add explicit mapping between _CRS GpioIo() resources and their names used in the driver.

2017-06-22NFC: st-nci: Covert to use GPIO descriptorAndy Shevchenko
Since we got rid of platform data, the driver may use GPIO descriptor directly. Looking deeply to the use of the GPIO pin it looks like it should be a GPIO based reset control rather than custom GPIO handling. But this is out of scope of the change.

2017-06-22NFC: st-nci: Get rid of "interesting" use of interrupt polarityAndy Shevchenko
I2C and SPI frameworks followed by IRQ framework do set interrupt polarity correctly if it's properly specified in firmware (ACPI or DT). Get rid of the redundant trick when requesting interrupt.

2017-06-22NFC: st-nci: Get rid of platform dataAndy Shevchenko
Legacy platform data must go away. We are on the safe side here since there are no users of it in the kernel. If anyone by any odd reason needs it the GPIO lookup tables and built-in device properties at your service.

2017-06-16networking: make skb_push & __skb_push return void pointersJohannes Berg
It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) @@ expression SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - fn(SKB, LEN)[0] + *(u8 *)fn(SKB, LEN) Note that the last part there converts from push(...)[0] to the more idiomatic *(u8 *)push(...).

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. - HCI_DM_VDC_MEASUREMENT_VALUE: Allow to measure the field applied on the CLF antenna. A value between 0 and 0x0f is returned. 0 is maximum. - HCI_DM_FWUPD_START: Allow to put CLF into firmware update mode. It is a specific CLF command as there is no GPIO for this. - HCI_DM_FWUPD_END: Allow to complete firmware update. - HCI_DM_VDC_VALUE_COMPARISON: Allow to compare the field applied on the CLF antenna to a reference value. - MANUFACTURER_SPECIFIC: Allow to retrieve manufacturer specific data received during a NCI_CORE_INIT_CMD.
