As3525 v1/v2 Add power savings menu
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 Change-Id: I04137682243be92f0f8d8bf1cfa54fbb1965559b TODO: add other players?
