| 553 | + * This is a huge hack to workaround a problem where the dw_hdmi i2c |
---|
| 554 | + * bus could sometimes get wedged. Once wedged there doesn't appear |
---|
| 555 | + * to be any way to unwedge it (including the HDMI_I2CM_SOFTRSTZ) |
---|
| 556 | + * other than pulsing the SDA line. |
---|
| 557 | + * |
---|
| 558 | + * We appear to be able to pulse the SDA line (in the eyes of dw_hdmi) |
---|
| 559 | + * by: |
---|
| 560 | + * 1. Remux the pin as a GPIO output, driven low. |
---|
| 561 | + * 2. Wait a little while. 1 ms seems to work, but we'll do 10. |
---|
| 562 | + * 3. Immediately jump to remux the pin as dw_hdmi i2c again. |
---|
| 563 | + * |
---|
| 564 | + * At the moment of remuxing, the line will still be low due to its |
---|
| 565 | + * recent stint as an output, but then it will be pulled high by the |
---|
| 566 | + * (presumed) external pullup. dw_hdmi seems to see this as a rising |
---|
| 567 | + * edge and that seems to get it out of its jam. |
---|
| 568 | + * |
---|
| 569 | + * This wedging was only ever seen on one TV, and only on one of |
---|
| 570 | + * its HDMI ports. It happened when the TV was powered on while the |
---|
| 571 | + * device was plugged in. A scope trace shows the TV bringing both SDA |
---|
| 572 | + * and SCL low, then bringing them both back up at roughly the same |
---|
| 573 | + * time. Presumably this confuses dw_hdmi because it saw activity but |
---|
| 574 | + * no real STOP (maybe it thinks there's another master on the bus?). |
---|
| 575 | + * Giving it a clean rising edge of SDA while SCL is already high |
---|
| 576 | + * presumably makes dw_hdmi see a STOP which seems to bring dw_hdmi out |
---|
| 577 | + * of its stupor. |
---|
| 578 | + * |
---|
| 579 | + * Note that after coming back alive, transfers seem to immediately |
---|
| 580 | + * resume, so if we unwedge due to a timeout we should wait a little |
---|
| 581 | + * longer for our transfer to finish, since it might have just started |
---|
| 582 | + * now. |
