+Subject: [PATCH 071/156] Added support for HiFiBerry DAC+
 
 The driver is based on the HiFiBerry DAC driver. However HiFiBerry DAC+ uses
 a different codec chip (PCM5122), therefore a new driver is necessary.

+Subject: [PATCH 122/156] Extend clock timeout, fix modprobe baudrate
  parameter.
 
 Set the BSC_CLKT clock streching timeout to 35ms as per SMBus specs.\n- Increase priority of baudrate parameter passed to modprobe (in /etc/modprobe.d/*.conf or command line). Currently custom baudrates don't work because they are overridden by clock-frequency in the platform_device passed to the function.

+
+This is required at least for SPDIF. If the bitrate goes above,
+videocore will either resample the audio or corrupt it due to
+underruns. Supposedly the hardware isn't designed to output
+higher rates, but it can still resample it down to supported
+rates.
+
+Some code is based on ac97_pcm.c.

+
+Report all layouts supported by the HDMI protocol to userspace.
+Make the videocore set the correct layout according to the
+userspace request.
+
+Some code taken from patch_hdmi.c. In particular, the HDMI channel
+layout table was copied without changes - with the idea in mind that
+hopefully it can be shared one day. Or at least updating it will be
+simpler.
+
+In my tests, everything appears to work, except when outputting
+FL FR RL RR. Then my receiver outputs RL on both the RL and RR
+speakers, while RR is never heard.

+Subject: [PATCH 132/156] bcm2835: access controls under the audio mutex
+
+I don't think the ALSA framework provides any kind of automatic
+synchronization within the control callbacks. We most likely need
+to ensure this manually, so add locking around all access to shared
+mutable data. In particular, bcm2835_audio_set_ctls() should
+probably always be called under our own audio lock.

+Subject: [PATCH 133/156] bcm2835: always use 2/4/8 channels for multichannel
+ layouts
+
+Pad the unused channels with NA. This means userspace needs to write
+additional, silent padding channels, which is not ideal, but better
+than noise.
+
+Works around noise at the following channel counts: 3, 5, 6, 7

+Subject: [PATCH 134/156] bcm2835: only allow stereo if analogue jack is
+ selected
+
+Sending more than 2 channels to videocore while outputting to analogue
+mysteriously outputs heavy artifacts. So just paint it over with a
+hack: if analogue is explicitly selected as destination, do not
+reporting support for anything other than stereo.
+
+I'm not sure how to deal with the auto case (destination 0). There's
+probably way to retrieve this and even to listen to plug events, but
+I didn't find one yet, and it's probably not worth the trouble. Just
+don't use this setting, I guess. Unless you like noise.
+
+Changing the setting while an audio stream is active also doesn't
+work properly. We could probably interrupt running streams by
+returning ENODEV or using kernel hotplug stuff (maybe), but that
+also doesn't seem worth the trouble.

+Subject: [PATCH 135/156] bcm2835: interpolate audio delay
+
+It appears the GPU only sends us a message all 10ms to update
+the playback progress. Other than this, the playback position
+(what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all.
+Userspace will see jitter up to 10ms in the audio position.
+
+Make this a bit nicer for userspace by interpolating the
+position using the CPU clock.
+
+I'm not sure if setting snd_pcm_runtime.delay is the right
+approach for this. Or if there is maybe an already existing
+mechanism for position interpolation in the ALSA core.
+
+I only set SNDRV_PCM_INFO_BATCH because this appears to remove
+at least one situation snd_pcm_runtime.delay is used, so I have
+to worry less in which place I have to update this field, or
+how it interacts with the rest of ALSA.
+
+In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY.
+One problem is that it requires sending a videocore message, and
+waiting for a reply, which could make the implementation much
+harder due to locking and synchronization requirements.

+Subject: [PATCH 136/156] bcm2835-sdhost: Add workaround for odd behaviour on
+ some cards
+
+For reasons not understood, the sdhost driver fails when reading
+sectors very near the end of some SD cards. The problem could
+be related to the similar issue that reading the final sector
+of any card as part of a multiple read never completes, and the
+workaround is an extension of the mechanism introduced to solve
+that problem which ensures those sectors are always read singly.

+Subject: [PATCH 138/156] BCM270X_DT: Add sdio_overclock parameter to sdio
+ overlay
+
+The sdio_overclock parameter is like the overclock_50 parameter, i.e.
+it sets an alternate frequency (in MHz) to use when the MMC framework
+requests 50MHz, except that it applies to the SDIO bus.
+
+Be aware that the actual frequencies achievable are limited to even integer
+divisions of 250MHz, and that the driver will round up to include fractions
+(e.g. 62 will include 62.5) but then round down to the nearest frequency.
+In other words, the chosen frequency is the highest possible that is less than
+the parameter value + 1. In practise this means that 62 is the only sensible
+value.
+
+Examples:
+  250MHz/4 = 62.5MHz (sdio_overclock=62)
+  250MHz/2 = 125MHz (sdio_overclock=125) # Too fast

+Subject: [PATCH 139/156] rtc: ds1307: add support for the DT property
+ 'wakeup-source'
+
+For RTC chips with no IRQ directly connected to the SoC, the RTC chip
+can be forced as a wakeup source by stating that explicitly in
+the device's .dts file using the "wakeup-source" boolean property.
+This will guarantee the 'wakealarm' sysfs entry is available on the
+device, if supported by the RTC.
+
+With these changes to the driver rtc-ds1307 and the necessary entries
+in the .dts file, I get an working ds1337 RTC on the Witty Pi extension
+board by UUGear for the Raspberry Pi.
+
+An example for the entry in the .dts file:
+
+	rtc: ds1337@68 {
+		compatible = "dallas,ds1337";
+		reg = <0x68>;
+		wakeup-source;
+
+If the "wakeup-source" property is set, do not request an IRQ.
+Set also UIE mode to unsupported, to get a working 'hwclock' binary.

+
+This is an interim patch to verify that problems seen with
+some cards can be worked around at the expense of an increased
+CPU load by forcing PIO mode.
+
+Although this could have used the brcm,force-pio attribute, that
+is a boolean (true if present, false if absent) and attributes
+can't be deleted by overlays. Instead, make brcm,pio-limit
+unfeasibly high instead to allow DMA to be re-enabled using the
+pio_limit parameter of the sdhost or sdtweak overlays.

+Overwriting the baudrate module parameter creates an apparent

+being initialised.

+Also fix whitespace errors.

+24db_digital_gain DT param can be used to specify that PCM512x
+codec "Digital" volume control should not be limited to 0dB gain,
+and if specified will allow the full 24dB gain.

+ parsing
+
+The DT bindings for pinctrl-bcm2835 allow both the function and pull
+to contain either one entry or one per pin. However, an error in the
+DT parsing can cause failures if the number of pulls differs from the
+number of functions.

+Subject: [PATCH 149/156] bcm2835-sdhost: Major revision
+
+This is a significant revision of the bcm2835-sdhost driver. It
+improves on the original in a number of ways:
+
+1) Through the use of CMD23 for reads it appears to avoid problems
+   reading some sectors on certain high speed cards.
+2) Better atomicity to prevent crashes.
+3) Higher performance.
+4) Activity logging included, for easier diagnosis in the event
+   of a problem.

+Subject: [PATCH 154/156] Updated smsc95xx driver to check for a valid MAC
+ address in eeprom before using smsc95xx.macaddr parameter passed on command
+ line.
+
+The built-in RPi adaptor will still get a MAC address based on the parameter passed on the command line as the RPi hardware does not have an eeprom,
+however usb->ethernet adaptors using the same driver should have an eeprom with MAC address as part of their hardware and therefore will use this
+meaning they don't end up with the same MAC address as the built-in RPi adaptor.
