2016-05-15iPod Classic: modify USB storage read/write buffers sizeCástor Muñoz
The write buffer size is undefined to use the default 24Kb. size defined (and recomended) in usb_storage.c, the read buffer size is also decremented to 24 Kb. USB sequential read and write benchmarks using diskdump are now 8-9% faster. Change-Id: Ia7c9f77b57c8ca5b566b508efffbd713d1587acf

2016-05-15iPod Classic: prepare i2c and PMU for bootloaderCástor Muñoz
When the bootloader starts only IRAM is available, the first task is to ask the PMU to verify if the iPod has previously been hibernated by OF. Due to memory limitations, the kernel cannot be used on this stage. This patch modifies I2C and PMU low level functions to not to depend on kernel (removes mutexes, and uses HW timer instead of current_tick), actual kernel functions are modified to be 'mutexed' wrappers of the new functions.

2015-12-17iPod Classic: s5l8702 clocking rewrite+documentationCástor Muñoz
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.

2015-10-07ipod Classic: implement HAVE_RECORDINGCástor Muñoz
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 Change-Id: I7e20fd3ecaa83b1c58d5c746f5153fe5c3891d75
2015-10-07iPod Classic: capture support for CS42L55 codecCástor Muñoz
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.

2015-10-07iPod Classic: use new PL080 DMA driverCástor Muñoz
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
2015-10-07iPod Classic: introduce PL080 DMA controller driverCástor Muñoz
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.

2015-10-07iPod Classic: s5l8702 GPIO interrupt controller.Cástor Muñoz
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.

2015-02-02iBasso DX50/DX90: Major code cleanup and reorganization.Udo Schläpfer
Reorganization - Separated iBasso devices from PLATFORM_ANDROID. These are now standlone hosted targets. Most device specific code is in the firmware/target/hosted/ibasso directory. - No dependency on Android SDK, only the Android NDK is needed. 32 bit Android NDK and Android API Level 16. - Separate implementation for each device where feasible. Code cleanup - Rewrite of existing code, from simple reformat to complete reimplementation. - New backlight interface, seperating backlight from touchscreen. - Rewrite of device button handler, removing unneeded code and fixing memory leaks. - New Debug messages interface logging to Android adb logcat (DEBUGF, panicf, logf). - Rewrite of lcd device handler, removing unneeded code and fixing memory leaks. - Rewrite of audiohw device handler/pcm interface, removing unneeded code and fixing memory leaks, enabling 44.1/48kHz pthreaded playback. - Rewrite of power and powermng, proper shutdown, using batterylog results (see http://gerrit.rockbox.org/r/#/c/1047/). - Rewrite of configure (Android NDK) and device specific config. - Rewrite of the Android NDK specific Makefile. Misc - All plugins/games/demos activated. - Update tinyalsa to latest from https://github.com/tinyalsa/tinyalsa. Includes - http://gerrit.rockbox.org/r/#/c/993/ - http://gerrit.rockbox.org/r/#/c/1010/ - http://gerrit.rockbox.org/r/#/c/1035/ Does not include http://gerrit.rockbox.org/r/#/c/1007/ due to new backlight interface and new option for hold switch, touchscreen, physical button interaction. Rockbox needs the iBasso DX50/DX90 loader for startup, see http://gerrit.rockbox.org/r/#/c/1099/ The loader expects Rockbox to be installed in /mnt/sdcard/.rockbox/. If /mnt/sdcard/ is accessed as USB mass storage device, Rockbox will exit gracefully and the loader will restart Rockbox on USB disconnect. Tested on iBasso DX50.

2015-01-29yp-r0: improve the charging codeLorenzo Miori
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.
