Some old code made the assumption that CONFIG_CPU == AS3525v2 if and only if
HAVE_AS3543, which is not true on targets like the Samsung YP-R0. This fixes
several issues on such targets like a huge volume gap between -39dB and -40dB
and a volume artificially capped at -72dB instead of -82dB.

This is a rewrite of the clocking section, the resulting system
frequencies are the same as the current git version.
This pàtch uses fixed FClk and just one register is written to switch
all system frequencies, it needs less steps than the current git
version to reach the desired frequency, so it is faster and safer.
Includes functions to step-up/down over a table of predefined set of
frequencies.
The major difference is that Vcore is decreased from 1050 to 1000 mV.
See clocking-s5l8702.h for more information.

This patch has been tested on iPod 80 and 160slim, actually
it works but some updates must be done to the final version:
- unlimitted input buffer
- decrease CHUNK_SIZE
- use non-cached addresses instead of discard d-cache ???
Capture hardware versions:
Ver iPod models capture support
--- ----------- ---------------
0 80/160fat dock line-in
1 120/160slim dock line-in + jack mic
HW version 1 includes an amplifier for the jack plug mic.
Capture HW detection only tested on iPod 80 and 160slim.
CODEC power:
AFAIK, OF powers CS42L55 at VA=2.4V for capture (1.8V for
playback) and turns on the ADC charge pump. CODEC datasheet
recommmends to disable the charge pump for VA>2.1V.
CS42L55 DS, s4.13 (Required Initialization Settings): for
VA>2.1V, some adjustments "must" be done using undocummented
"control port compensation" registers. OF does not modifies
these registers when VA=2.4V.
This patch configures capture HW in the same way as OF does.
TODO:
- ADC full scale voltage depends on VA, perform tests to find
clipping levels for VA=1.8V and VA=2.4V

There are a couple of power saving options that can be selected using
defines, they configure the CODEC in a different way than OF does:
MONO_MIC: jack microphone is connected to left channel, disabling
right channel saves ~1 mW, there is no reason to not to do it.
BYPASS_PGA: this option only applies to the line-in, OF does not
bypass the PGA and configures it to 0 dB gain. At the beginning,
this patch was written based on CODEC datasheet, bypassing PGA
because it saves power and incrementes dinamic range ~1dB, i have
used this setup for a while without problems. Finally this option
was disabled at the last minute, i decided to do it after reviewing
the OF and realizing that CS42L55 datasheet recommends to bypass the
PGA only if the HW includes a couple of capacitors (see Typical
Connection Diagram, Note 4), at this moment i don't know if Classic
includes these capacitors (probably not). Anyway, i am not able to
tell the difference listening to voice recodings.
TODO:
- Use variable PGA gain for jack microphone (it is fixed to +12 dB.
as OF does).
- I am not a fan of having lots of unused #define options, these could
be useful for a generic driver but actually this driver is Classic
oriented, i am not sure if it could be considered disirable to
eliminate them in the final version.

This patch uses the new pl080 DMA driver for I2S playback and LCD
update. I have tried to be as fiel as possible to the current
behaviour, algorithms and configurations are the same, but using
the new driver. Other modifications:
Playback:
- CHUNK_SIZE is decreased from 42988 to 8188 bytes, it does not
affect normal playback (block size 1024), was tested using
metronome (block size 46080). This change is needed because the
new code commits d-cache range instead of commiting the whole
d-cache, maximum time spent commiting the range should be
limited, CHUNK_SIZE can be decreased even more if necessary.
- pcm_play_dma_start() calls pcm_play_dma_stop() to stop the
channel when it is running (metronome replays the tick sound
without stopping the channel).
- pcm_play_dma_get_peak_buffer(): same as actual SVN function but
returns samples count instead of bytes count.
TODO: AFAIK, actually this function is not used in RB. Not tested,
but probably this function will fail because it returns pointers
to the internal double buffer.
LCD update:
- suppresses lcd_wakeup semaphore and uses yield()
Change-Id: I79b8aa47a941e0dd91847150618f3f7f676c26ef
Motivation:
This driver began as a set of functions to help to test and
experiment with different DMA configurations. It is cumbersome,
time consuming, and leads to mistakes to handle LLIs and DMA
registers dispersed along the code.
Later, i decided to adapt an old DMA queue driver written in the
past for a similar (scatter-gather) controller, all task/queue
code is based on the old driver.
Finally, some cleaning and dmac_ch_get_info() function was added
to complete RB needs.
Description:
- Generic, can be used by other targets including the same
controller. Not difficult to adapt for other similar
controllers if necesary.
- Easy to experiment and compare results using different
setups and/or queue algorithms:
Multi-controller and fully configurable from an unique place.
All task and LLI management is done by the driver, user only
has to (statically) allocate them.
- Two queue modes:
QUEUE_NORMAL: each task in the queue is launched using a new
DMA transfer once previous task is finished.
QUEUE_LINK: when a task is queued, it is linked with the last
queued task, creating a single continuous DMA transfer. New
tasks must be queued while the channel is running, otherwise
the continuous DMA transfer will be broken.
On Classic, QUEUE_LINK mode is needed for I2S continuous
transfers, QUEUE_NORMAL is used for LCD and could be useful
in the future for I2C or UART (non-blocking serial debug) if
necessary.
- Robust DMA transfer progress info (peak meter), needs final
testing, see below.
Technical details about DMA progress:
There are comments in the code related to the method actually
used (sequence method), it reads progress without halting the
DMA transfer. Althought the datasheet does not recommend to do
that, the sequence method seems to be robust, I ran tests calling
dmac_ch_get_info() millions of times and the results were always
as expected (tests done at 2:1 CPU/AHB clock ratio, no other
ratios were tried but probably sequence method will work for any
typical ratio).
This controller allows to halt the transfer and drain the DMAC
FIFO, DMA requests are ignored when the DMA channel is halted.
This method is not suitable for playback because FIFO is never
drained to I2S peripheral (who raises the DMA requests). This
method probably works for capture, the FIFO is drained to memory
before halting.
Another way is to disable (stop) the playback channel. When the
channel is disabled, all FIFO data is lost. It is unknown how much
the FIFO was filled when it was cleared, SRCADDR counter includes
the lost data, therefore the only useful information is LINK and
COUNT, that is the same information disponible when using the
sequence method. At this point we must procced in the same way as
in sequence method, in addition the playback channel should be
relaunched (configure + start) after calculating real SRCADDR.
The stop+relaunch method should work, it is a bit complicated,
and not valid for all peripheral FIFO configurations (depending
on stream rate). Moreover, due to the way the COUNT register is
implemented in HW, I suspect that this method will fail when
source and destination bus widths doesn't match. And more
important, it is not easy to garantize that no sample is lost
here or there, using the sequence method we can always be sure
that playback is ok.

This patch implements a simple API to use the external interrupt
hardware present on s5l8702 (GPIO interrupt controller). This
GPIOIC has been fully tested using emcore apps.
Code is based on openiBoot project, there are a few modifications
to optimize space considering we will only use two or three external
interrupts. The API compiles and works, but has been never used,
therefore probably will need some changes to the final version.
External interrupts are necessary for jack remote+mic controller
(see iAP Interface Specifiction: Headphone Remote and Mic System),
this controller is located at I2C bus address 0x72, there is a IRQ
line for remote button press/release events routed to GPIO E6. At
this moment, the functionallity of this controller has been
extensively tested using emcore, getting a lot of information about
how it works. Microphone is already working on RB, jack accessory
detection and button events are work in progress.
PMU IRQ line is also routed to GPIO F3, it signals many events:
holdswitch, usb plug, wall adapter, low battery... The use of PMU
interrupts is the orthodox way of doing things, at this moment
there is no work done in this direction, there are a lot of PMU
events and i think it is a matter of discursion what to do and how.

Some people reported strange charging times and
strange battery life.
Charging by OF: 25 hours; RB: 18 hours
It has been found that there are at least two issues here:
1) the way of getting battery charging status wasn't
really accurate. This attempts to fix that issue.
This patch also simplifies some code (opening a
device is no more needed, for example).
To technically explain, battery charging implies first a constant
current mode (where the voltage increases) and then a constant
voltage mode (where, obviously, the voltage reads more or less
the same). The old way the End Of Charge was detected was based solely
on the voltage, while now it is based on chip's EOC interrupt,
which should be more accurate.
2) OF explicitly sets a constant current 350 mA, while we usually had
55 mA (by as3543 default).
This wasn't discovered before since there is a caching problem
("an accurate guess") in the Samsung power mgmt Linux module,
thus its debugging dumper wasn't really working, reporting a 55 mA current.
Strangely this option should have been set by the bootloader
but apparently it does not.
Some testing is still needed, but I confirm that with this patch
I could run a benchmark for 25 hours (vs. 18 hours), by charging
within Rockbox of course.

The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations
known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs
Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual
to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed
./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk
the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)
The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.
Until we have found a proper way to install it, it can only be installed following the instructions of Ilia on his
bitbucket page, using the CWM-OF and his installation script package.
