Hi! How can I change the clock mapping? I am using Bananian Linux (A20) on a Banana Pro and would like to use PLL6 to drive the APB1/UART clock to achieve higher baud rates than the 1.5MBaud possible in the default configuration.
<sbruec>
There seems to be a sysfs interface to the clock manager /sys/class/ccu but I am unsure how to use it.

after I change BoardConfig.mk, will it automatically rebuild what is needed or do I need to rebuild the world?

hello, i made some progress on the mainline I2S DAI driver for A20 sun7i, now the modules are loading, alsamixer show something, and the device nodes are there..
<sunxi_fan>
anyway when i try to "aplay" something a wav file, i get back a "invalid argument". i filled a report on alsa ML, http://article.gmane.org/gmane.linux.alsa.devel/141169 but i suppose it's of interest here too..
<sunxi_fan>
it's of course VERRY rough and the HW registers are maybe still off (i tried to get inspiration from AW legacy linux-sunxi 3.4 driver, but maybe no one ever used it.. who knows if they works..) anyway i'm still working/debugging the infrastructure so that issue will come later, i suppose..
<fullstop>
sunxi_fan: I've written an ASoC driver for TI Davinci and an older wolfson dac
<fullstop>
and you're right, it's difficult to find documentation.
<fullstop>
your best bet would be to look at other drivers for inspiration
<plaes>
sunxi_fan: please add link to your email + gist to the Mainlining effort page

yes, i looked at a lot of drivers and their implementation but the crazy thing is that surely each one is working NOW but at a different stage of implementation of Alsa (and generic kernel.. like dmaengine/regmap) API!!

some are "whole" implementation of machine/platform/DAI/codec, some others are using the simple-card approach, that i really believe, if it works.. :) , to be the simplest approach indeed from a LOC efficiency.. (few lines for something working..) but maybe requires the DAI iimplementor to be more aware of all the dynamic bindings of a ASoC framework.
<sunxi_fan>
fullstop: did you ASoC driver is mapped on a simple-card template? i found quite good and well written the Frescale SAI: sound/soc/fsl/fsl_sai.c
<fullstop>
Yes, there are a lot of different flavors. I based mine off of machine/platform/DAI/codec
<sunxi_fan>
plaes: really i should update the wiki, maybe at a later time, when the "stuff" will be more cooked/mature; don't want to push the "casual user" to enter this process because it would be still too raw..
<plaes>
there might be some casual users who might hack on it..
<mripard>
plaes: no.
<mripard>
the mainlining effort page should really point only to patches that have been posted

it has the "Left to be done" page

s/page/section
<mripard>
yeah, and it should be updated to say that someone works on it
<mripard>
but definitely not link to a driver that doesn't even work.
<plaes>
thanks.. moved some items around
<plaes>
mripard: you have you ever submitted 'A31 Audio Codec' stuff?
<mripard>
nope
<mripard>
that falls in the "doesn't even work" category ;)
<plaes>
ok

hello, i am trying to install u-boot 2015.07rc2 to NAND on an A20, does anyone have a link ? i am able to install and boot from a sd card, but i am missing something to make it work on NAND. thanks!

okay, now I have the camera looking for /dev/video1
<fullstop>
but I'm starting to think that the sun7i_tvd driver is incomplete.

fullstop, is that a ntsc or pal camera you're using?
<fullstop>
no camera at the moment
<fullstop>
but NTCS would be desired

I replaced camera.cfg with that of the working stock image and rebuilt the camera libraries. I don't know if camera.cfg influences compile-time things or not.
