From f118301416953d677de738100c33eb8cfb7adecb Mon Sep 17 00:00:00 2001 From: Jean Delvare <khali@linux-fr.org> Date: Thu, 22 Sep 2005 21:58:41 +0200 Subject: [PATCH] i2c-viapro: Implement I2C Block transactions Implement the I2C block transactions on VIA chips which support them: VT82C686B, VT8233, VT8233A, VT8235 and VT8237R. This speeds up EEPROM accesses by a factor 10 or so. I would like to thank Antonino A. Daplas, Hinko Kocevar, Salah Coronya and Andreas Henriksson for their help in testing this new feature.
