[PATCH 01/10] drm/mgag200: Set DDC timeout in milliseconds

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Compute the i2c timeout in jiffies from a value in milliseconds. The
original values of 2 jiffies equals 2 milliseconds if HZ has been
configured to a value of 1000. This corresponds to 2.2 milliseconds
used by most other DRM drivers. Update mgag200 accordingly.
