Hi, L4hackers,
I am implementing I2C drivers from native linux to L4Linux. I am using Freescale iMX6Q SD board. Kernel version 3.14
in ./drivers/i2c/busses/i2c-imx.c, function i2c_imx_probe(),
devm_clk_get() is called. And fails at here. I understand that clock are initialized from function "__init imx6q_clocks_init()". I managed to compile and call the imx6q_clocks_init() function from L4Linux, but encountered many problem.
The question is, Is it necessary to initialize clocks in L4Linux and how?
Thanks in advance?
