+	 * restrict the number of mf values to be checked.
+	 *
+	 * Furthermore, conditions (4) and (5) only restrict the range of
+	 * acceptable p1 and mf values by modifying the minimum and maximum
+	 * limits. (5) can be expressed as
+	 *
+	 *	ext_clock / (div * mf / p1) * m * mf >= out_clock_min

+	 *	mf <= ext_clock * p1 / (int_clock_min * div)

+ * (Possible) TODOs:
+ *
+ * - PM for serializer and remote peripherals. We need to manage:
+ *   - VPOC
+ *     - Power domain? Regulator? Somehow any remote device should be able to
+ *       cause the VPOC to be turned on.
+ *   - Link between the deserializer and the serializer
+ *     - Related to VPOC management. We probably always want to turn on the VPOC
+ *       and then enable the link.
+ *   - Serializer's services: i2c, gpios, power
+ *     - The serializer needs to resume before the remote peripherals can
+ *       e.g. use the i2c.
+ *     - How to handle gpios? Reserving a gpio essentially keeps the provider
+ *       (serializer) always powered on.
+ * - Do we need a new bus for the FPD-Link? At the moment the serializers
+ *   are children of the same i2c-adapter where the deserializer resides.
+ * - i2c-atr could be made embeddable instead of allocatable.

+ *   t5 is fixed, and is 6000uS,

+ *
+ * This start-up time can be optimized a bit more, if we start the writes
+ * over I2C after (t4+t6), but before (t4+t5) expires. But then sensor
+ * initialization over I2C may complete before (t4+t5) expires, and we must
+ * ensure that capture is not started before (t4+t5).
+ *
+ * This delay doesn't account for the power supply startup time. If needed,

+/*
+ * MT9V111 is a 1/4-Inch CMOS digital image sensor with an integrated
+ * Image Flow Processing (IFP) engine and a sensor core loosely based on
+ * MT9V011.
+ *
+ * The IFP can produce several output image formats from the sensor core
+ * output. This driver currently supports only YUYV format permutations.
+ *
+ * The driver allows manual frame rate control through s_frame_interval subdev
+ * operation or V4L2_CID_V/HBLANK controls, but it is known that the
+ * auto-exposure algorithm might modify the programmed frame rate. While the
+ * driver initially programs the sensor with auto-exposure and
+ * auto-white-balancing enabled, it is possible to disable them and more
+ * precisely control the frame rate.
+ *
+ * While it seems possible to instruct the auto-exposure control algorithm to
+ * respect a programmed frame rate when adjusting the pixel integration time,
+ * registers controlling this feature are not documented in the public
+ * available sensor manual used to develop this driver (09005aef80e90084,
+ * MT9V111_1.fm - Rev. G 1/05 EN).
