Sorry for the delays, hoping to send out the fixes today or Friday after
scanning emails one more time for more fixes.

Do you know when these patches are going to be merged to mainline? 4.4-rc2 is
out, but it does not include them.

[PATCH v4 0/3] ARM: OMAP2+ McASP(3) support for DRA7xx family

2015-11-11 Thread Peter Ujfalusi 
Hi Tony,

Changes since v3:
- rebased on mainline's HEAD
- Added Tested-by from Felipe
- Added Acked-by from Paul for the hwmod patches

Changes since v2:
- DTS patch added which is needed because of the clock handling changes

Felip Balbi reported that linux-next is broken right now since the DTS part of
the earlier series has been applied, but we do not have the mcasp hwmod in the
kernel:
...
[0.181029] platform 48468000.mcasp: Cannot lookup hwmod 'mcasp3'
...
[6.121072] davinci-mcasp 48468000.mcasp: _od_fail_runtime_resume: FIXME: 
missing hwmod/omap_dev info

[6.145576] 4400.ocp:L3 Custom Error: MASTER MPU TARGET L4_PER2_P3 
(Read): Data Access in User mode during Functional access
...

This is the followup series for the hwmod changes needed to get audio working
on DRA7xx family based boards.
The DTS patches has been applied by Tony from the original series:
http://www.spinics.net/lists/linux-omap/msg121473.html

I have addressed your comments in the hwmod data and did some research also
regarding to the use of ahclkx as fclk in the original submission.
It turned out that McASP _needs_ all clocks to be enabled (fclk, iclk and
ahclkx/r) to be able to access registers. The original patch where we handled
the ahclkx as fclk worked, because the fclk clock got enabled in the HW w/o
any SW interaction.
All in all, the McASP found in DRA7 needs all clocks to be enabled.
To satisfy this I have introduced a new flag to hwmod, which means that the
listed optional clocks need to be handled alongside with the fclk clock.

Regards,
Peter
