+ * context, as this function may be called in parallel with the same
+ * transformation object. Data processing can happen synchronously
+ * [SHASH] or asynchronously [AHASH] at this point.
+ * @final: Retrieve result from the driver. This function finalizes the

+ * pushes it back to upper layers. No data processing happens at this
+ * point.
+ * @finup: Combination of @update and @final. This function is effectively a
+ * combination of @update and @final calls issued in sequence. As some
+ * hardware cannot do @update and @final separately, this callback was
+ * added to allow such hardware to be used at least by IPsec. Data
+ * processing can happen synchronously [SHASH] or asynchronously [AHASH]
+ * at this point.
+ * @digest: Combination of @init and @update and @final. This function
+ * effectively behaves as the entire chain of operations, @init,
+ * @update and @final issued in sequence. Just like @finup, this was
+ * added for hardware which cannot do even the @finup, but can only do
+ * the whole transformation in one run. Data processing can happen
+ * synchronously [SHASH] or asynchronously [AHASH] at this point.
+ * @setkey: Set optional key used by the hashing algorithm. Intended to push
+ * optional key used by the hashing algorithm from upper layers into
+ * the driver. This function can store the key in the transformation
+ * context or can outright program it into the hardware. In the former
+ * case, one must be careful to program the key into the hardware at
+ * appropriate time and one must be careful that .setkey() can be
+ * called multiple times during the existence of the transformation
+ * object. Not all hashing algorithms do implement this function as it
+ * is only needed for keyed message digests. SHAx/MDx/CRCx do NOT
+ * implement this function. HMAC(MDx)/HMAC(SHAx)/CMAC(AES) do implement
+ * this function. This function must be called before any other of the
+ * @init, @update, @final, @finup, @digest is called. No data
+ * processing happens at this point.
+ * @export: Export partial state of the transformation. This function dumps the
+ * entire state of the ongoing transformation into a provided block of
+ * data so it can be @import 'ed back later on. This is useful in case
+ * you want to save partial result of the transformation after
+ * processing certain amount of data and reload this partial result
+ * multiple times later on for multiple re-use. No data processing

+ * These bus formats uniquely identify data formats on the data bus. Format 0
+ * is reserved, MEDIA_BUS_FMT_FIXED shall be used by host-client pairs, where
+ * the data format is fixed. Additionally, "2X8" means that one pixel is
+ * transferred in two 8-bit samples, "BE" or "LE" specify in which order those
+ * samples are transferred over the bus: "LE" means that the least significant
+ * bits are transferred first, "BE" means that the most significant bits are
+ * transferred first, and "PADHI" and "PADLO" define which bits - low or high,
+ * in the incomplete high byte, are filled with padding bits.
+ *
+ * The bus formats are grouped by type, bus_width, bits per component, samples
+ * per pixel and order of subsamples. Numerical values are sorted using generic
+ * numerical sort order (8 thus comes before 10).
+ *
+ * As their value can't change when a new bus format is inserted in the
+ * enumeration, the bus formats are explicitly given a numerical value. The next
+ * free values for each category are listed below, update them when inserting
+ * new pixel codes.

- * These pixel codes uniquely identify data formats on the media bus. Mostly
- * they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
- * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
- * data format is fixed. Additionally, "2X8" means that one pixel is transferred
- * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
- * transferred over the bus: "LE" means that the least significant bits are
- * transferred first, "BE" means that the most significant bits are transferred
- * first, and "PADHI" and "PADLO" define which bits - low or high, in the
- * incomplete high byte, are filled with padding bits.
- *
- * The pixel codes are grouped by type, bus_width, bits per component, samples
- * per pixel and order of subsamples. Numerical values are sorted using generic
- * numerical sort order (8 thus comes before 10).
- *
- * As their value can't change when a new pixel code is inserted in the
- * enumeration, the pixel codes are explicitly given a numerical value. The next
- * free values for each category are listed below, update them when inserting
- * new pixel codes.
