Report 5 (July 15 - July 21)

This is Report #5. I plan to post these every Sunday. They will give a rundown of what I've done during the week, list any problems I had, and what I plan to do the following week. I'll be posting the reports both to the beagle-gsoc Google Group and to my blog.

Completed this week:

• Minor fixes to allow device drivers to survive a bus driver restart.
• Rebased against mainline Minix
• Code merged into mainline Minix:
• kernel: i2c padconf workaround
• i2c: initial bus drivers for am335x and dm37xx
• Importing usr.sbin/i2cscan
• libi2cdriver: library for i2c device drivers
• cat24c256: driver for the cat24c256 i2c eeprom
• eepromread: simple program to view eeprom contents
• Documentation posted to the Minix Wiki:
• I2C Internals
• I2C Device Driver Protocol
• I2C Device Driver Programming
• Began the TDA19988 driver. So far it can detect if a display is connected, turn on the HDMI module, and read the revision information.

Issues / Concerns / Challenges:

• None this week :)

Plan for next week:

• EDID reading in the TDA19988 driver. Subtasks: enabling DDC, enabling interrupts, setting up the read, and reading the data.
• Begin frame buffer driver enhancements to use EDID to configure the driver properly.
