Only the low nibble is defined, and on at least one 3gx (mine) there is an
undefined bit which reads as a one -- bit 6 (0x40). This screwed tctrl_intr()
which would loop forever, thinking it always had new events to process.
tctrl now initializes the state of the internal LCD icons. The icons
are unprogrammed at boot time. This incidentally makes the DC-POWER icon
work.
Fixes:
Fix my stupidity in the ENVSYS stuff, and actually follow the API.
Add some undocumented commands to the ts102 registers file, and fix a few
typos.
Modifications to tctrl.c:
Add entrypoints to driver for open/close/ioctl/poll.
Make device work with apmd. (still no support for suspend/sleep)
Make device work with ENVSYS API.
Slightly restructure handling of events.
Add function to make microcontroller requests.
screen will turn off and when you open the lid screen turns on. If you
do too rapidly, the driver won't be notified but you can press the micro
switch and it will come back. Also "halt -p" now works so you don't
have to do Pause-P to powerdown.
do much yet (except for power down support). As sson as I figure
out to get its interrupts enabled, it will be much more functional.
(e.g., print console messages on low power warnings, be able to turn
off the TFT, etc.).
