1dfeba5702 Sansa Clip : ignore previous setting of CGU_DBOP (do not use ORR)

adb978a44d Sansa AMS: Various fixes/enhancements for clock frequencies
Fix CGU_DBOP setting

Set PCLK to the exact frequency (62MHz, not the maximal frequency)

Use a better comment for CLK_DIV macro

Use preprocessor safety checks for clock divider sizes to avoid future mistakes (not for SD_IDENT frequency since that check is handled by mci_set_clock_divider)

Use maximal IDE frequency of 66MHz (like OF), not 90MHz like written in AS3525 datasheet. The IDE chip is somehow linked to internal storage, and a too high frequency could affect the storage driver.

Use the same DBOP frequency of 32MHz for all models (like OF, verified clip, fuze, e200v2 and m200v4), compromise between performance and battery life could be added in the future for each target
Performance increase on Sansa Fuze with DBOP freq. set to 64MHz: +12% fps for lcd_update, +1% fps for yuv

Thanks to daytona955 on the forums for his help

4ed387d603 Fix reds and yellows (hopefully). Some targets apparently didn't properly #ifdef lcd_enable and lcd_sleep code out, so that it got partly active in the bootloader; rename the ui simulator stub fixes most reds; for the clip: move the hook code into lcd-1bit-vert.c which should fix the bootloader red.

b7739fbf1c Rework lcd_enabled and lcd_set/call_enable hook
a) lcd_enabled() is now lcd_active(), and is available for HAVE_LCD_SLEEP only targets (e.g. ipod video) too. It was depandent on HAVE_LCD_ENALE only before
b) rename the hook accordingly, and implement the hook for other other targets too (e.g. the clip [the only mono target with lcd_enable/lcd_sleep yet, so the code is still in the lcd driver], ipod, fuze, c200)

9856a37de3 Sansa Clip: revert 19353
If we don't set pin B6 to 1, display can go off at random times

3648e87054 Add small delays before lcd_write_data() and lcd_write_command(). This seems to be needed on some clips (i.e. mine)

45711ac286 Sansa AMS: centralize clock settings in clock-target.h
Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding

603a9c7c7d Clip: add backlight and buttonlight code
Revive lcd_enable() as well, and use it in _backlight_on/off()
Don't update the lcd framebuffer if the display is off

8df1a7e29a e200v2: implement the backlight handling (copy/paste from the c200v1/e200v1 code - this should probably be unified, along with other upcoming v2 code), plus clean up the lcd init by calling lcd_init() directly in the bootloader, instead of lcd_init_device().
