2026c9506c Commit the ascodec-as3525.c/ascodec-target.h changes from FS#12452 that keep ascodec_read/write_pmu from keeping interrupts disabled for the full duration of two I2C transfers, which can contribute to I2S PUSH/POP FIFO under/over-flows. 'Tis peppered with a couple interrupt safety mods as well.

12375d1d3a Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them.

61c90fbf3f as3525: cache first read of enrd0 register
We need it for correct charger detection if we boot with charger plugged
because there is no edge interrupt

df34a4767f as3525 ascodec: make internal functions statics and remove some details for ascodec-target.h header
reorder static functions to avoid the need for early prototypes
panic if the INT_AUDIO callback could not read the 3 IRQ_ENRD registers

7dd0297a4d as3525: correctly detect usb status if we boot with USB plugged

88c55d7290 as3514/as3543 fixes
- Enable end of charge monitoring once, it doesn't need to be disabled
- Acknowledge the first (wrong) end of charge interrupt on charger enable
  (this had been broken in r25299)
- Centralize reads to ENRD* registers and cache the results when needed
    - on PP it is not needed because reads are atomic, we only check for
      end of charge when the charging, and for charger presence when
      discharging

as3525v2 (using as3543) specifics
- I got the datasheet today from AMS, thanks to them for being so fast
  and not require me to sign tons of papers!
- USB detection now works on as3525v2 using the as3543. Clip+ won't
  reboot to OF yet, it needs mkamsboot support first (usbstack disabled)
- Charging should work, the CHARGER register is at a different place, it
  is an extended PMU register -> use ascodec_read/write_charger() to
  access it
- real interrupts are not used yet for ENRD, we get thousands of
  interrupts per second, apparently only limited by the i2c clock.

9067c915ad Use I2C2_DACNT register (number of pending i2c bytes to read/write) to determine if an ascodec i2c transfer is done. This should fix i2c problems with MMU enabled.

49c25816f0 Sansa AMS i2c : fix 2 problems identified by Jack Halpin & Bertrik Sikken

070ee525ac Patch by Rafaël Carré - Sansa AMS i2c :
* remove peripheral reset (already made in system_init).
  * Move empty i2c_init() from i2c-as3525.c (and remove that file)
