Subject: [PATCH v3 0/2] i2c: change id to let i2c-gpio work
Date: Mon, 15 Oct 2012 17:30:26 +0800 [thread overview]
Message-ID: <1350293428-24551-1-git-send-email-voice.shen@atmel.com> (raw)
The i2c core driver will turn the platform device ID to busnum
When using platfrom device ID as -1, it means dynamically assigned
the busnum. When writing code, we need to make sure the busnum,
and call i2c_register_board_info(int busnum, ...) to register device
if using -1, we do not know the value of busnum
In order to solve this issue, set the platform device ID as a fix number
Here using 0 to match the busnum used in i2c_regsiter_board_info()
