Changes
Open Firmware
- 3515 OLPC XO-4 - EC Code 0.3.08
- 3514 OLPC XO-4 - rework DCON freeze and unfreeze screen synchronisation, make wait-output global as requested by John.
- 3513 OLPC ARM - DCON unfreeze glitch reduction on 1.2 GHz SKUs. Increased the delay between waking screen and enabling DCONLOAD. Set scan line register in device setup. Solves #12394. Does not change #12377.
- 3512 OLPC camera driver - trac #12436 - turn off camera power domain in open method if sensor not found; fixes failure to suspend.
- 3509 OLPC XO-1.75 XO-4 - bat-status@ gave an EC command result timeout on XO-1.75, caused by EC API version being treated as cross-platform when it should not have been. XO-4 no longer needs EC API version 4 support, so remove it.
- 3507 OLPC XO-4 - touchscreen, update version to 0.0.0.10, print version in decimal, rely on CForth for clearing pull-up on TOUCH_HD#, change polarity of TOUCH_HD#, breaks automatic update from version 0.0.0.9 and earlier. #12391
CForth
- disable pull-up on TOUCH_HD# signal from touchscreen controller and IR PCB,
EC
- see EC 0.3.08
Touchscreen
- reverse polarity of the host disable signal,
