Once we did this, problems went away.\n\nWhile trying to dig into this problem and some others, I found that\nthe proper documentation for the Type C PHY was available to me. This\nallowed me to cleanup the magic numbers in the funtion that I was\ntouching and also fix a few minor issues that (luckily) haven't caused\nany problems yet.\n\nI also found that aux channel communications were flaky on some\nadapters until I adjusted the voltage swing.\n\nFor this series I've added Chris Zhong's Reviewed-by tags to some of\nthe patches since he gave a +1 to nearly identical patches on the\nChrome OS gerrit and I didn't think he'd mind me carrying his tag. If\nfolks would rather I didn't do that, please yell.\n\nChanges in v2:\n- Removed extra blank line\n- Voltage swing patch new for v2.\n\nDouglas Anderson (4):\n phy: rockchip-typec: Set the AUX channel flip state earlier\n phy: rockchip-typec: Avoid magic numbers + add delays in aux calib\n phy: rockchip-typec: Do the calibration more correctly\n phy: rockchip-typec: Don't set the aux voltage swing to 400 mV\n\n drivers/phy/rockchip/phy-rockchip-typec.c | 246 ++++++++++++++++++++++++------\n 1 file changed, 201 insertions(+), 45 deletions(-)" }
