82aff3ea3b NFC: nfcmrvl: avoid being stuck on FW dnld timeout
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.

b2fe288eac NFC: nfcmrvl: free reset gpio
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.

1dbac5c578 NFC: nfcmrvl: fix SPI driver dependencies
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.

893a84e818 NFC: nfcmrvl: Auto-select core module
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.

15203b4c79 NFC: nfcmrvl: Add setup handler
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.
