-PCM512x and TAS575x audio CODECs/amplifiers
-
-These devices support both I2C and SPI (configured with pin strapping
-on the board). The TAS575x devices only support I2C.
-
-Required properties:
-
-  - compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141",
-                 "ti,pcm5142", "ti,pcm5242", "ti,tas5754" or "ti,tas5756"
-
-  - reg : the I2C address of the device for I2C, the chip select
-          number for SPI.
-
-  - AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
-    device, as covered in bindings/regulator/regulator.txt
-
-Optional properties:
-
-  - clocks : A clock specifier for the clock connected as SCLK.  If this
-    is absent the device will be configured to clock from BCLK.  If pll-in
-    and pll-out are specified in addition to a clock, the device is
-    configured to accept clock input on a specified gpio pin.
-
-  - pll-in, pll-out : gpio pins used to connect the pll using <1>
-    through <6>.  The device will be configured for clock input on the
-    given pll-in pin and PLL output on the given pll-out pin.  An
-    external connection from the pll-out pin to the SCLK pin is assumed.
-    Caution: the TAS-desvices only support gpios 1,2 and 3

+Userspace-driven timers
+=======================
+
+:Author: Ivan Orlov <ivan.orlov0322@gmail.com>
+
+Preface
+=======
+
+This document describes the userspace-driven timers: virtual ALSA timers
+which could be created and controlled by userspace applications using
+IOCTL calls. Such timers could be useful when synchronizing audio
+stream with timer sources which we don't have ALSA timers exported for
+(e.g. PTP clocks), and when synchronizing the audio stream going through
+two virtual sound devices using ``snd-aloop`` (for instance, when
+we have a network application sending frames to one snd-aloop device,
+and another sound application listening on the other end of snd-aloop).
+
+Enabling userspace-driven timers
+================================
+
+The userspace-driven timers could be enabled in the kernel using the
+``CONFIG_SND_UTIMER`` configuration option. It depends on the
+``CONFIG_SND_TIMER`` option, so it also should be enabled.
+
+Userspace-driven timers API
+===========================
+
+Userspace application can create a userspace-driven ALSA timer by
+executing the ``SNDRV_TIMER_IOCTL_CREATE`` ioctl call on the
+``/dev/snd/timer`` device file descriptor. The ``snd_timer_uinfo``
+structure should be passed as an ioctl argument:
+
+::
+
+    struct snd_timer_uinfo {
+        __u64 resolution;
+        int fd;
+        unsigned int id;
+        unsigned char reserved[16];
+    }
+
+The ``resolution`` field sets the desired resolution in nanoseconds for
+the virtual timer. ``resolution`` field simply provides an information
+about the virtual timer, but does not affect the timing itself. ``id``
+field gets overwritten by the ioctl, and the identifier you get in this
+field after the call can be used as a timer subdevice number when
+passing the timer to ``snd-aloop`` kernel module or other userspace
+applications. There could be up to 128 userspace-driven timers in the
+system at one moment of time, thus the id value ranges from 0 to 127.
+
+Besides from overwriting the ``snd_timer_uinfo`` struct, ioctl stores
+a timer file descriptor, which can be used to trigger the timer, in the
+``fd`` field of the ``snd_timer_uinfo`` struct. Allocation of a file
+descriptor for the timer guarantees that the timer can only be triggered
+by the process which created it. The timer then can be triggered with
+``SNDRV_TIMER_IOCTL_TRIGGER`` ioctl call on the timer file descriptor.
+
+So, the example code for creating and triggering the timer would be:
+
+::
+
+    static struct snd_timer_uinfo utimer_info = {
+        /* Timer is going to tick (presumably) every 1000000 ns */
+        .resolution = 1000000ULL,
+        .id = -1,
+    };
+
+    int timer_device_fd = open("/dev/snd/timer",  O_RDWR | O_CLOEXEC);
+
+    if (ioctl(timer_device_fd, SNDRV_TIMER_IOCTL_CREATE, &utimer_info)) {
+        perror("Failed to create the timer");
+        return -1;
+    }
+
+    ...
+
+    /*
+     * Now we want to trigger the timer. Callbacks of all of the
+     * timer instances binded to this timer will be executed after
+     * this call.
+     */
+    ioctl(utimer_info.fd, SNDRV_TIMER_IOCTL_TRIGGER, NULL);
+
+    ...
+
+    /* Now, destroy the timer */
+    close(timer_info.fd);
+
+
+More detailed example of creating and ticking the timer could be found
+in the utimer ALSA selftest.
+
+Userspace-driven timers and snd-aloop
+-------------------------------------
+
+Userspace-driven timers could be easily used with ``snd-aloop`` module
+when synchronizing two sound applications on both ends of the virtual
+sound loopback. For instance, if one of the applications receives sound
+frames from network and sends them to snd-aloop pcm device, and another
+application listens for frames on the other snd-aloop pcm device, it
+makes sense that the ALSA middle layer should initiate a data
+transaction when the new period of data is received through network, but
+not when the certain amount of jiffies elapses. Userspace-driven ALSA
+timers could be used to achieve this.
+
+To use userspace-driven ALSA timer as a timer source of snd-aloop, pass
+the following string as the snd-aloop ``timer_source`` parameter:
+
+::
+
+  # modprobe snd-aloop timer_source="-1.4.<utimer_id>"
+
+Where ``utimer_id`` is the id of the timer you created with
+``SNDRV_TIMER_IOCTL_CREATE``, and ``4`` is the number of
+userspace-driven timers device (``SNDRV_TIMER_GLOBAL_UDRIVEN``).
+
+``resolution`` for the userspace-driven ALSA timer used with snd-aloop
+should be calculated as ``1000000000ULL / frame_rate * period_size`` as
+the timer is going to tick every time a new period of frames is ready.
+
+After that, each time you trigger the timer with
+``SNDRV_TIMER_IOCTL_TRIGGER`` the new period of data will be transferred
+from one snd-aloop device to another.
