00bda90a21 iPod Classic: add non-cached memory region
Configures uncached memory region and adds some defines for misc HW,
for compability with the bootloader and other future use, current
functionality should not be affected.

348bfc5c8f iPod Classic: clickwheel fixes
Uses GPIO.E2 (Request To Send) to detect the holdswitch status,
it is a temporal workaround that seems to work on all models.

Holdswitch status must be detected to drive low GPIO.E2 (RTS)
and GPIO.E4 (Data Out) when the holdswitch is locked, otherwise
battery life decreases about 25%.

Holdswitch unlock action is detected by reading the HELLO message
that the external wheel controller sends when it is powered on,
this allows to quickly capture clickwheel activity after unlock.
GPIO.E2 is also used in case the HELLO message is missed because
the holdswitch was unlocked before Rockbox/bootloader starts.

These 2 lines (RTS and DOUT) can not be used to transmit messages
to the external clickwheel controller, not a problem, actually no
messages are sent while normal operation, only at initialization
stage.

f753b8ead1 iPod Classic: s5l8702 clocking rewrite+documentation
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.

f47f04b65f hwstub: Add ajt213x lua interface for DSP block
With this you can upload and run code on DSP core in atj213x.

The files can be produced using as2181. You can download
this assembler from https://github.com/wodz/as2181
You should use extended mode (-x switch) since DSP core
in atj is non standard and uses 24bit operands.
PX register has different meaning as well and is used as MSB
when loading other registers with immediates (immediate field
is 16bit in instruction so to set register to 24bit value
you need to store MSB in PX prior to this).

MAC MR is 56bit accordingly.

HIP interface seems to be mapped at standard addresses
(except that regular 218x doesn't have HIP).

Have a fun!

a507bb2837 YH8xx,YH9xx: Keymap improvement
The main "innovation" in this patch are two "virtual buttons"
for the record switch on YH92x targets. When the switch state
changes, a single BUTTON_REC_SW_ON or .._OFF button event will
be generated. Thus keymap code can react on switching, but
not on the actual state of the switch.

Wherever sensible, the following user scheme is applied:
- use PLAY as confirm button
- use REW button or Long REW to exit
- use REC (YH820) or FFWD (YH92X) as modifier key for button combos

a8758c953d Fix scrolling left button inadvertently cancels listtree
Depending on the actual keymap, canceling a listtree with the
"scroll left" button may not be intended, especially
if the list is entered from a completely different focus
(think of leaving a plugin with "long left")

Note:
initializing "scrolling_left" with true without anything actually
scrolling sounds odd to me... maybe this variable should be renamed?
"pgleft_allow_cancel" comes to my mind (with opposite boolean states)

32b4558511 iPod Classic: initialize USB power configuration
This patch limits the drawn USB current to 100/500mA, instead of
the actual 200/1000mA settings. It also initializes other USB power
related GPIOs.

Solves some USB disconnect issues: FS#12990, FS#12956. I am using a
powered USB HUB with no problems (Vusb=5.05V unloaded), but there
are lots of USB disconnects when using the motherboard USB ports
(Vusb=4.91V), this patch solves all my issues.

Actually, it seems that the USB current drain is limited to 1000mA,
when a load peak occurs most USB2 ports deliver more than 500mA, as
current consumption increases the USB voltage decreases, an excesive
voltage drop produces USB disconnections. Limiting USB current drain
to 500mA also limits the voltage drop, preventing subsequent USB
failures.

Anyway, to minimize voltage drop, it is recommended to use quality
cables and preferably connect to USB ports with higher Vusb.

291b2338c9 ipod Classic: implement HAVE_RECORDING
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

42abc6a496 iPod Classic: capture support for CS42L55 codec
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.

67b4e7f958 iPod Classic: use new PL080 DMA driver
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()

d6ee2c9eaf iPod Classic: introduce PL080 DMA controller driver
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.

609cde9468 iPod Classic: s5l8702 GPIO interrupt controller.
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.
