Hi Igor
Can you give me IMX6Q kernel git address supporting LPDDR2 suspend and resume?We need download all kernel source code.
Many thanks.
there is no IMX6Q reference board with LPDDR2,
so no bsp/git. You can port SCM patches to this kernel.
Best regards
igor

Our kernel version is as follows:
1 VERSION = 3
2 PATCHLEVEL = 10
