2010-04-29 12:10:30 Kernel drivers build sequence query
Appalayagari Sreedhar (INDIA)
I am working with the custom BF533 board 2009R1-RC3 distribution. In my board there is a i2c based gpio expander pca555 and USB HC, the USB reset is coming from one of the gpio expander output pin.
The PCA555 is interfaced with BF533 (PF0 and PF1 as SCL and SDA.)
I am trying to use the i2c bit bang driver.
When the kernel boots the
i2c gpio driver is enabled only after the USB HC init over. this does not helps me since the USB reset needs to be applied to the USB HC.
For this how i can bring the i2c driver init first before other driver init. I tried bringing the i2c driver in kconfig and Makefile upwards but still no use.
Thank you, Sreedhar

build them as modules and load them in the order you need
