when battery_bench is run
exports a file in the rockbox directory called 'battery_levels.default'
if the user wants their own levels they can rename the file battery_levels.cfg
and it will be loaded at boot
some minimal error checking is performed prior to using the values
added manual entry

Allow user to select cpu undervolt
There have been quite a few issues across the SANSA AMS line related
to CPU undervolting while most players show greatly increased runtime
some crash.
Rather than constanly upping the voltage we now have a
setting with a safe value for all players and the option for lower voltages
I plan to add a few other options here later such as disk
timings and maybe some other clocks/experimental settings
Added: Disk Low speed option for AS3525v2 devices cuts
frequency to 12 MHz from 24 MHz
Added: Disk Low speed option for AS3525v1 devices cuts
frequency to 15.5 MHz from 31 MHz
Added: I2c Low Speed AS3525 devices, should be bigger improvement for v1 devices
Fixed: Debug menu for AS3525v2 No SDSLOT frequency,
Showed IDE freq though it is unused
Added: DBOP and SSP underclocking affects display on v1/v2 respectively
Fixed: debug menu now has SSP frequency, and SSP_CPSR
Update: made settings menu more generic
Update: cleaned up code
Added: Clip v1 & Fuze v1 didn't have HAVE_ADJUSTABLE_CPU_VOLTAGE.
not sure why but, waiting on testing to confirm
Added: C200v2 and E200v2 devices and HAVE_ADJUSTABLE_CPU_VOLTAGE.
Fixed: v1 devices don't like display timing set lower (dbop)
v1 devices don't have a divider set for ssp (causes divide by 0)
Fixed: ClipZip display lags with Max SSP divider changed from 0xFE to 0x32
Fixed: v1 devices didn't work properly with highspeed sd cards
Added code from http://gerrit.rockbox.org/r/#/c/1704/
Added powersave and IDE interface enable/disable
Added: V2 devices now have powersave enabled on sd interface
Update: cleaned up code, lang defines, added manual entries
Update ssp clock mechanism added calculated ssp divider to clipzip
Update turn display clock off when clip+ turns off display
Fixed: clipzip wrong register for SSP clock

TODO: add other players?
Saves 100+ bytes (50 of it in iram), saves a bit of power
Internal LCD clock decreased but with added efficiency of drawing routines
loses only around 2 Hz on the scanrate (~75Hz) while fps is slightly increased
Column offsets are now calculated outside the loops saving a few instructions
Passing a LCD_NOP command after lcd_update turns off Data/Cmd# gpio
saving a bit more power
Added a function lcd_write_cmd_triple() that allows 3 commands to be sent at once
when enabled with LCD_USE_FIFO_FOR_COMMANDS it sends them back to back without
checking FIFO status in between or sending to thhe D/C# Gpio.
Makes an assumption about the FIFO being large enough to
accept 3 commands after being emptied which should be the case on the
clipv1, clipv2, clipplus. I have only enabled it for the clip plus
as thats the only device I have to test it on.
On clip+ the SSP clock is now turned off when screen is off

move prototypes to ascodec.h
move code to ascodec*.c
YPR0: use adc-as3514.c instead of duplicating it
TODO: merge as3514.h and ascodec.h ?

The new controller framebuffer (different from what is in clipv1/clipv2 and some clip+) has 128 columns, the old has 132 columns and is centered on the screen.

Charge using 150mA current like the OF to charge faster
Edit clipv2 charging curve with 150mA

Do not use a static variable for buttons, else they're never reset
Remove unneeded code
Move GPIO_DIR setting to init function

Initial button driver for clip+. I've followed the steps the OF uses to read the buttons.
There is no hold button on the clip+ so for now calling button_hold() siply returns false.
The OF actually sets an additional flag for the 2nd read from D6 and not BUTTON_POWER as I have done here.

Now making the Fuzev2 bootloader build should be pretty easy
TODO:
- write button driver (FlynDice found all buttons already)
- find button light
- decide if lcd-ssd1303.c must be modified for Clip+ using SSP or forked
- check if backlight code works (I copied Clipv2 code)
