Code Releases Activity

ASoC: Updates for v4.18 

This is a very big update, mainly due to a huge set of new drivers some
 of which are individually very large.  We also have a lot of fixes for
 the topology stuff, several of the users have stepped up and fixed some
 the serious issues there, and continued progress on the transition away
 from CODEC specific drivers to generic component drivers.
 
  - Many fixes for the topology code, including fixes for the half done
    v4 ABI compatibility from Guenter Roeck and other ABI fixes from
    Kirill Marinushkin.
  - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
    de Goode.
  - More followups on removing legacy CODEC things and transitioning to
    components from Morimoto-san.
  - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
  - A series of fixes and updates to the rather elderly Cirrus Logic SoC
    drivers from Alexander Sverdlin.
  - Qualcomm DSP support from Srinivas Kandagatla.
  - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
    MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
    RT5668 and TI TSCS454

Qualcomm APR (Asynchronous Packet Router) binding
This binding describes the Qualcomm APR. APR is a IPC protocol for
communication between Application processor and QDSP. APR is mainly
used for audio/voice services on the QDSP.
- compatible:
Usage: required
Value type: <stringlist>
Definition: must be "qcom,apr-v<VERSION-NUMBER>", example "qcom,apr-v2"
- reg
Usage: required
Value type: <u32>
Definition: Destination processor ID.
Possible values are :
1 - APR simulator
2 - PC
3 - MODEM
4 - ADSP
5 - APPS
6 - MODEM2
7 - APPS2
= APR SERVICES
Each subnode of the APR node represents service tied to this apr. The name
of the nodes are not important. The properties of these nodes are defined
by the individual bindings for the specific service
- All APR services MUST contain the following property:
- reg
Usage: required
Value type: <u32>
Definition: APR Service ID
Possible values are :
3 - DSP Core Service
4 - Audio Front End Service.
5 - Voice Stream Manager Service.
6 - Voice processing manager.
7 - Audio Stream Manager Service.
8 - Audio Device Manager Service.
9 - Multimode voice manager.
10 - Core voice stream.
11 - Core voice processor.
12 - Ultrasound stream manager.
13 - Listen stream manager.
= EXAMPLE
The following example represents a QDSP based sound card on a MSM8996 device

help
I2S controller on EP93xx seems to have undocumented HW issue.
Underflow of internal I2S controller FIFO could confuse the
state machine and the whole stream can be shifted by one byte
until I2S is disabled. This option enables IRQ based watchdog
which disables and re-enables I2S in case of underflow and
fills FIFO with zeroes.
If you are unsure how to answer this question, answer Y.
