Subject: [PATCH] <SMBus block read I2C emulation>, <i2c-2.8.1>
Date: Thu, 19 May 2005 06:24:27 +0000 [thread overview]
Message-ID: <200311271749.52305.lt@ncic.ac.cn> (raw)
Hello!
Here is the patch to support SMBus Block Read and SMBus Block Process Call
protocols under I2C emulation. It adds the I2C_M_RECV_LEN flag.
To support the two protocols, an algorithm driver should handle the
I2C_M_RECV_LEN flag in its master_xfer routin, and return
I2C_FUNC_SMBUS_EMUL | I2C_FUNC_SMBUS_READ_BLOCK_DATA or
I2C_FUNC_SMBUS_EMUL | I2C_FUNC_SMBUS_BLOCK_PROC_CALL
in its functionality routin.
Existing algorithm drivers won't be affected by this patch.

Regards,
Liu Tao
