- * computers) from user space. It exports the /dev/rtc interface supporting
- * various ioctl() and also the /proc/rtc pseudo-file for status
- * information.
- *
- * The ioctls can be used to set the interrupt behaviour and generation rate
- * from the RTC via IRQ 8. Then the /dev/rtc interface can be used to make
- * use of these timer interrupts, be they interval or alarm based.
- *
- * The /dev/rtc interface will block on reads until an interrupt has been
- * received. If a RTC interrupt has already happened, it will output an
- * unsigned long and then block. The output value contains the interrupt
- * status in the low byte and the number of interrupts since the last read
- * in the remaining high bytes. The /dev/rtc interface can also be used with
- * the select(2) call.

+          - 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
+
+          Sound is provided by the ALSA USB Audio/MIDI driver. Therefore
+          if you don't want to use the device solely for RDS receiving,
+          it is recommended to also select SND_USB_AUDIO.
+
+          Please have a look at the documentation, especially on how
+          to redirect the audio stream from the radio to your sound device:
+          Documentation/video4linux/si470x.txt
+
           Say Y here if you want to connect this type of radio to your
           computer's USB port.

- * Device driver for the PCMCIA controller module of the
- * Hitachi HD64465 handheld companion chip.
- *
- * Note that the HD64465 provides a very thin PCMCIA host bridge
- * layer, requiring a lot of the work of supporting cards to be
- * performed by the processor.  For example: mapping of card
- * interrupts to processor IRQs is done by IRQ demuxing software;
- * IO and memory mappings are fixed; setting voltages according
- * to card Voltage Select pins etc is done in software.
- *
- * Note also that this driver uses only the simple, fixed,
- * 16MB, 16-bit wide mappings to PCMCIA spaces defined by the
- * HD64465.  Larger mappings, smaller mappings, or mappings of
- * different width to the same socket, are all possible only by
- * involving the SH7750's MMU, which is considered unnecessary here.
- * The downside is that it may be possible for some drivers to
- * break because they need or expect 8-bit mappings.
- *
- * This driver currently supports only the following configuration:
- * SH7750 CPU, HD64465, TPS2206 voltage control chip.
