/* A driver for the D-Link DSB-R100 USB radio and Gemtek USB Radio 21.
- The device plugs into both the USB and an analog audio input, so this thing
- only deals with initialisation and frequency setting, the
- audio data has to be handled by a sound driver.
-
- Major issue: I can't find out where the device reports the signal
- strength, and indeed the windows software appearantly just looks
- at the stereo indicator as well. So, scanning will only find
- stereo stations. Sad, but I can't help it.
-
- Also, the windows program sends oodles of messages over to the
- device, and I couldn't figure out their meaning. My suspicion
- is that they don't have any:-)

- History:
-
- Version 0.46:
- Removed usb_dsbr100_open/close calls and radio->users counter. Also,
- radio->muted changed to radio->status and suspend/resume calls updated.
-
- Version 0.45:
- Converted to v4l2_device.
-
- Version 0.44:
- Add suspend/resume functions, fix unplug of device,
- a lot of cleanups and fixes by Alexey Klimov <klimov.linux@gmail.com>
-
- Version 0.43:
- Oliver Neukum: avoided DMA coherency issue
-
- Version 0.42:
- Converted dsbr100 to use video_ioctl2
- by Douglas Landgraf <dougsland@gmail.com>
-
- Version 0.41-ac1:
- Alan Cox: Some cleanups and fixes
-
- Version 0.41:
- Converted to V4L2 API by Mauro Carvalho Chehab <mchehab@infradead.org>
-
- Version 0.40:
- Markus: Updates for 2.6.x kernels, code layout changes, name sanitizing
-
- Version 0.30:
- Markus: Updates for 2.5.x kernel and more ISO compliant source
-
- Version 0.25:
- PSL and Markus: Cleanup, radio now doesn't stop on device close
-
- Version 0.24:
- Markus: Hope I got these silly VIDEO_TUNER_LOW issues finally
- right. Some minor cleanup, improved standalone compilation
-
- Version 0.23:
- Markus: Sign extension bug fixed by declaring transfer_buffer unsigned
-
- Version 0.22:
- Markus: Some (brown bag) cleanup in what VIDIOCSTUNER returns,
- thanks to Mike Cox for pointing the problem out.
-
- Version 0.21:
- Markus: Minor cleanup, warnings if something goes wrong, lame attempt
- to adhere to Documentation/CodingStyle
-
- Version 0.2:
- Brad Hards <bradh@dynamite.com.au>: Fixes to make it work as non-module
- Markus: Copyright clarification
-
- Version 0.01: Markus: initial release

+ *
+ * The formula above is written as below to keep it on one

+ *
+ * l / 10^6 = w / e * a
+ *
+ * Let's mark w * a by x:

+ *
+ * Thus, we get:
+ *
+ * x = l * e / 10^6
+ *
+ * The strobe width must be at least as long as requested,
+ * thus rounding upwards is needed.
+ *
+ * x = (l * e + 10^6 - 1) / 10^6
+ * -----------------------------
+ *
+ * Maximum possible accuracy is wanted at all times. Thus keep

+ * Calculate a, assuming maximum w, with rounding upwards:
+ *
+ * a = (x + (2^16 - 1) - 1) / (2^16 - 1)
+ * -------------------------------------
+ *
+ * Thus, we also get w, with that a, with rounding upwards:

+ * w = (x + a - 1) / a
+ * -------------------
+ *
+ * To get limits:
+ *
+ * x E [1, (2^16 - 1) * (2^8 - 1)]
+ *
+ * Substituting maximum x to the original formula (with rounding),
+ * the maximum l is thus
+ *
+ * (2^16 - 1) * (2^8 - 1) * 10^6 = l * e + 10^6 - 1
