SUPPORTED SERIES: - NWZ-E450 - NWZ-E460 - NWZ-E470 - NWZ-E580 - NWZ-A10 NOTES: - bootloader makefile convert an extra font to be installed alongside the bootloader since sysfont is way too small - the toolsicon bitmap comes from the Oxygen iconset - touchscreen driver is untested TODO: - implement audio routing driver (pcm is handled by pcm-alsa) - fix playback: it crashes on illegal instruction in DEBUG builds - find out why the browser starts at / instead of /contents - implement radio support - implement return to OF for usb handling - calibrate battery curve (NB: of can report a battery level on a 0-5 scale but probabl don't want to use that ?) - implement simulator build (we need a nice image of the player) - figure out if we can detect jack removal POTENTIAL TODOS: - try to build a usb serial gadget and gdbserver Change-Id: Ic77d71e0651355d47cc4e423a40fb64a60c69a80

/* How backlight works:
|
|
*
|
|
* The brightness interface is a bit strange. There 6 levels: 0 throught 5.
|
|
* Level 0 means backlight off. When changing brightness, one sets level to the
|
|
* target brightness. The driver is gradually change the brightness to reach the
|
|
* target level. The step parameters control how many hardware steps will be done.
|
|
* For example, setting step to 1 will brutally change the level in one step.
|
|
* Setting step to 2 will change brightness in two steps: one intermediate and
|
|
* finally the target one. The more steps, the more gradual the transition. The
|
|
* period parameters controls the speed to changes between steps. Using this
|
|
* interface, one can achieve fade in/out at various speeds. */

/* FB extensions:
|
|
*
|
|
* Sony added relatively complicated extensions to the framebuffer. They allow
|
|
* better control of framebuffer refresh, double-buffering and mixing with DSP
|
|
* (v4l2). Each outout (LCD and TV) has two buffers, called page 0 and 1 (or A
|
|
* and B). Each page has its own attributes (image info) that control
|
|
* transparency, rotation and updates. At any point in time, the LCD is drawing
|
|
* a page and one can select the next page to draw. Unless an UPDATE ioctl()
|
|
* is made to change it, the next page will be the same as the one being drawn.
|
|
*
|
|
* FIXME I don't know what the timer is, it seems irrelevant for the LCD but
|
|
* the OF uses it for TV, maybe this controls the refresh rate of the TV output?
|
|
* Also it only exists on early version (up to generation x60 roughly)
|
|
*
|
|
* On a side note, this information only applies to a subset of LCD types (the
|
|
* LCD type can be gathered from icx_sysinfo):
|
|
* - BB(0): AQUILA BB LCD
