2015-11-05NFC: nfcmrvl: avoid being stuck on FW dnld timeoutVincent Cuissard1-3/+9
FW Download procedure can block on del_timer_sync because the timer is not running. This patch check that timer is scheduled before cancelling it. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2015-11-05NFC: nfcmrvl: free reset gpioVincent Cuissard1-0/+3
Reset GPIO shall be freed by the driver since the device used in devm_ calls can be still valid on unregister. If user removes the module and inserts it again, the devm_gpio_request will fail because the underlying physical device (e.g i2c) was not removed so the device management won't have freed the gpio.

2015-11-05NFC: nfcmrvl: add a small wait after setting UART breakVincent Cuissard1-1/+3

2015-11-05NFC: nfcmrvl: avoid UART break control during FW downloadVincent Cuissard1-4/+6

2015-11-05NFC: nfcmrvl: fix SPI driver dependenciesArnd Bergmann1-1/+1
The newly added nfcmrvl_spi driver uses the spi_nci infrastructure, but does not have a Kconfig dependency on that, so we can get a link-time error: drivers/built-in.o: In function `nfcmrvl_spi_nci_send': (.text+0x1428dc): undefined reference to `nci_spi_send' drivers/built-in.o: In function `nfcmrvl_spi_probe': (.text+0x142a24): undefined reference to `nci_spi_allocate_spi' drivers/built-in.o: In function `nfcmrvl_spi_int_irq_thread_fn': (.text+0x142abc): undefined reference to `nci_spi_read' This clarifies the dependency.

2015-10-27NFC: nfcmrvl: add firmware download supportVincent Cuissard7-10/+718
Implement firmware download protocol for Marvell NFC controllers. This protocol is based on NCI frames that's why parts of its implementation use some NCI generic functions. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2015-10-19NFC: nfcmrvl: Auto-select core moduleJean Delvare1-7/+5
As I understand it, the core nfcmrvl module is useless without either the USB or the UART access module. So hide NFC_MRVL and select it automatically if either NFC_MRVL_USB or NFC_MRVL_UART is selected. This avoids presenting NFC_MRVL when neither NFC_MRVL_USB nor NFC_MRVL_UART can be selected.

2014-01-07NFC: nfcmrvl: Add setup handlerAmitkumar Karwar2-0/+21
Marvell nfc device provides support for external coexistance control. It allows Device Host to inhibit the NFCC from polling when required by asserting a GPIO pin. A second pin allows the DH to have feedback on the current NFCC state. The required configuration for this feature is done in setup handler.
