+/**
+ * struct clk_ops - Callback operations for hardware clocks; these are to
+ * be provided by the clock implementation, and will be called by drivers
+ * through the clk_* api.
+ *
+ * @prepare: Prepare the clock for enabling. This must not return until
+ * the clock is fully prepared, and it's safe to call clk_enable.
+ * This callback is intended to allow clock implementations to
+ * do any initialisation that may sleep. Called with
+ * prepare_lock held.
+ *
+ * @unprepare: Release the clock from its prepared state. This will typically
+ * undo any work done in the @prepare callback. Called with
+ * prepare_lock held.
+ *
+ * @enable: Enable the clock atomically. This must not return until the
+ * clock is generating a valid clock signal, usable by consumer
+ * devices. Called with enable_lock held. This function must not
+ * sleep.
+ *
+ * @disable: Disable the clock atomically. Called with enable_lock held.
+ * This function must not sleep.
+ *
+ * @recalc_rate Recalculate the rate of this clock, by quering hardware. The
+ * parent rate is an input parameter. It is up to the caller to
+ * insure that the prepare_mutex is held across this call.
+ * Returns the calculated rate. Optional, but recommended - if
+ * this op is not set then clock rate will be initialized to 0.
+ *
+ * @round_rate: Given a target rate as input, returns the closest rate actually
+ * supported by the clock.
+ *
+ * @get_parent: Queries the hardware to determine the parent of a clock. The
+ * return value is a u8 which specifies the index corresponding to
+ * the parent clock. This index can be applied to either the
+ * .parent_names or .parents arrays. In short, this function
+ * translates the parent value read from hardware into an array
+ * index. Currently only called when the clock is initialized by
+ * __clk_init. This callback is mandatory for clocks with
+ * multiple parents. It is optional (and unnecessary) for clocks
+ * with 0 or 1 parents.
+ *
+ * @set_parent: Change the input source of this clock; for clocks with multiple
+ * possible parents specify a new parent by passing in the index
+ * as a u8 corresponding to the parent in either the .parent_names
+ * or .parents arrays. This function in affect translates an
+ * array index into the value programmed into the hardware.
+ * Returns 0 on success, -EERROR otherwise.
+ *
+ * @set_rate: Change the rate of this clock. If this callback returns
+ * CLK_SET_RATE_PARENT, the rate change will be propagated to the
+ * parent clock (which may propagate again if the parent clock
+ * also sets this flag). The requested rate of the parent is
+ * passed back from the callback in the second 'unsigned long *'
+ * argument. Note that it is up to the hardware clock's set_rate
+ * implementation to insure that clocks do not run out of spec
+ * when propgating the call to set_rate up to the parent. One way
+ * to do this is to gate the clock (via clk_disable and/or
+ * clk_unprepare) before calling clk_set_rate, then ungating it
+ * afterward. If your clock also has the CLK_GATE_SET_RATE flag
+ * set then this will insure safety. Returns 0 on success,
+ * -EERROR otherwise.
+ *
+ * The clk_enable/clk_disable and clk_prepare/clk_unprepare pairs allow
+ * implementations to split any work between atomic (enable) and sleepable
+ * (prepare) contexts. If enabling a clock requires code that might sleep,
+ * this must be done in clk_prepare. Clock enable code that will never be
+ * called in a sleepable context may be implement in clk_enable.
+ *
+ * Typically, drivers will call clk_prepare when a clock may be needed later
+ * (eg. when a device is opened), and clk_enable when the clock is actually
+ * required (eg. from an interrupt). Note that clk_prepare MUST have been
+ * called before clk_enable.

+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ * Index Key Name
+ * 0 FullyQualifiedDomainName
+ * 1 IntegrationServicesVersion
+ * 2 NetworkAddressIPv4
+ * 3 NetworkAddressIPv6
+ * 4 OSBuildNumber
+ * 5 OSName
+ * 6 OSMajorVersion
+ * 7 OSMinorVersion
+ * 8 OSVersion
+ * 9 ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.

- * As seen through Linux I2C, differences between the most common types of I2C
- * memory include:
- * - How much memory is available (usually specified in bit)?
- * - What write page size does it support?
- * - Special flags (16 bit addresses, read_only, world readable...)?
+/**
+ * struct at24_platform_data - data to set up at24 (generic eeprom) driver
+ * @byte_len: size of eeprom in byte
+ * @page_size: number of byte which can be written in one go
+ * @flags: tunable options, check AT24_FLAG_* defines
+ * @setup: an optional callback invoked after eeprom is probed; enables kernel
+ code to access eeprom via memory_accessor, see example
+ * @context: optional parameter passed to setup()
*
* If you set up a custom eeprom type, please double-check the parameters.
* Especially page_size needs extra care, as you risk data loss if your value
* is bigger than what the chip actually supports!
+ *
+ * An example in pseudo code for a setup() callback:
+ *
+ * void get_mac_addr(struct memory_accessor *mem_acc, void *context)
+ * {
+ * u8 *mac_addr = ethernet_pdata->mac_addr;
+ * off_t offset = context;
+ *
+ * // Read MAC addr from EEPROM
+ * if (mem_acc->read(mem_acc, mac_addr, offset, ETH_ALEN) == ETH_ALEN)
+ * pr_info("Read MAC addr from EEPROM: %pM\n", mac_addr);
+ * }
+ *
+ * This function pointer and context can now be set up in at24_platform_data.

+ *
+ * Jump labels provide an interface to generate dynamic branches using
+ * self-modifying code. Assuming toolchain and architecture support the result
+ * of a "if (static_key_false(&key))" statement is a unconditional branch (which
+ * defaults to false - and the true block is placed out of line).
+ *
+ * However at runtime we can change the branch target using
+ * static_key_slow_{inc,dec}(). These function as a 'reference' count on the key
+ * object and for as long as there are references all branches referring to
+ * that particular key will point to the (out of line) true block.
+ *
+ * Since this relies on modifying code the static_key_slow_{inc,dec}() functions
+ * must be considered absolute slow paths (machine wide synchronization etc.).
+ * OTOH, since the affected branches are unconditional their runtime overhead
+ * will be absolutely minimal, esp. in the default (off) case where the total
+ * effect is a single NOP of appropriate size. The on case will patch in a jump
+ * to the out-of-line block.
+ *
+ * When the control is directly exposed to userspace it is prudent to delay the
+ * decrement to avoid high frequency code modifications which can (and do)
+ * cause significant performance degradation. Struct static_key_deferred and
+ * static_key_slow_dec_deferred() provide for this.
+ *
+ * Lacking toolchain and or architecture support, it falls back to a simple
+ * conditional branch.
+ *
+ * struct static_key my_key = STATIC_KEY_INIT_TRUE;
+ *
+ * if (static_key_true(&my_key)) {
+ * }
+ *
+ * will result in the true case being in-line and starts the key with a single
+ * reference. Mixing static_key_true() and static_key_false() on the same key is not
+ * allowed.
+ *
+ * Not initializing the key (static data is initialized to 0s anyway) is the
+ * same as using STATIC_KEY_INIT_FALSE and static_key_false() is
+ * equivalent with static_branch().

+ * @PIN_CONFIG_BIAS_DISABLE: disable any pin bias on the pin, a

+ * pull-up in the process, this setting disables all biasing.
+ * @PIN_CONFIG_BIAS_HIGH_IMPEDANCE: the pin will be set to a high impedance
+ * mode, also know as "third-state" (tristate) or "high-Z" or "floating".
+ * On output pins this effectively disconnects the pin, which is useful
+ * if for example some other pin is going to drive the signal connected
+ * to it for a while. Pins used for input are usually always high
+ * impedance.
+ * @PIN_CONFIG_BIAS_PULL_UP: the pin will be pulled up (usually with high
+ * impedance to VDD). If the argument is != 0 pull-up is enabled,
+ * if it is 0, pull-up is disabled.
+ * @PIN_CONFIG_BIAS_PULL_DOWN: the pin will be pulled down (usually with high
+ * impedance to GROUND). If the argument is != 0 pull-down is enabled,
+ * if it is 0, pull-down is disabled.
+ * @PIN_CONFIG_DRIVE_PUSH_PULL: the pin will be driven actively high and
+ * low, this is the most typical case and is typically achieved with two
+ * active transistors on the output. Sending this config will enabale
+ * push-pull mode, the argument is ignored.
+ * @PIN_CONFIG_DRIVE_OPEN_DRAIN: the pin will be driven with open drain (open
+ * collector) which means it is usually wired with other output ports
+ * which are then pulled up with an external resistor. Sending this
+ * config will enabale open drain mode, the argument is ignored.
+ * @PIN_CONFIG_DRIVE_OPEN_SOURCE: the pin will be driven with open source
+ * (open emitter). Sending this config will enabale open drain mode, the
+ * argument is ignored.
+ * @PIN_CONFIG_INPUT_SCHMITT: this will configure an input pin to run in
+ * schmitt-trigger mode. If the schmitt-trigger has adjustable hysteresis,
+ * the threshold value is given on a custom format as argument when
+ * setting pins to this mode. The argument zero turns the schmitt trigger
+ * off.
+ * @PIN_CONFIG_INPUT_DEBOUNCE: this will configure the pin to debounce mode,
+ * which means it will wait for signals to settle when reading inputs. The
+ * argument gives the debounce time on a custom format. Setting the
+ * argument to zero turns debouncing off.
+ * @PIN_CONFIG_POWER_SOURCE: if the pin can select between different power
+ * supplies, the argument to this parameter (on a custom format) tells
+ * the driver which alternative power source to use.
+ * @PIN_CONFIG_LOW_POWER_MODE: this will configure the pin for low power
+ * operation, if several modes of operation are supported these can be
+ * passed in the argument on a custom form, else just use argument 1
+ * to indicate low power mode, argument 0 turns low power mode off.
+ * @PIN_CONFIG_END: this is the last enumerator for pin configurations, if
+ * you need to pass in custom configurations to the pin controller, use
+ * PIN_CONFIG_END+1 as the base offset.

-/* These all interelate for performance.
-**
-** If the journal block count is smaller than n transactions, you lose speed.
-** I don't know what n is yet, I'm guessing 8-16.
-**
-** typical transaction size depends on the application, how often fsync is
-** called, and how many metadata blocks you dirty in a 30 second period.
-** The more small files (<16k) you use, the larger your transactions will
-** be.
-**
-** If your journal fills faster than dirty buffers get flushed to disk, it must flush them before allowing the journal
-** to wrap, which slows things down. If you need high speed meta data updates, the journal should be big enough
-** to prevent wrapping before dirty meta blocks get to disk.
-**
-** If the batch max is smaller than the transaction max, you'll waste space at the end of the journal
-** because journal_end sets the next transaction to start at 0 if the next transaction has any chance of wrapping.
-**
-** The large the batch max age, the better the speed, and the more meta data changes you'll lose after a crash.
