v2:
- Add missing AESS memory banks.
- Update the serie base on comments related earlier serie:
http://www.mail-archive.com/[email protected]/msg69853.html
The location of the callback has been updated in order to fit with AESS.
Some call of PM runtime can be done by ASoC core when AESS is in RET so
we need to ensure that the additional callback is call on enable
also in order to have clock correctly stop.
v1:
ARM: OMAP4: Enable AESS IP.
This patch serie extends the the hwmod HWMOD_EXT_OPT_MAIN_CLK flag for the
AESS IP. This IP has additional register for Auto Gatting configuration. As
it is used only for Audio the driver is not always loaded. We can reuse the
same flag as McPDM to work around the HW problem due to bad reset value of
AESS Auto gatting configuration register.
If we try to setup and reset AESS during boot time without this serie the
next clocks will still remain enable.
