3.12-stable review patch. If anyone has any objections, please let me know.
------------------ From: Abhilash Kesavan <[email protected]> commit 2feed5aecf5f367b92bd6b6e92afe9e3de466907 upstream. The sysreg (system register) generates control signals for various blocks like disp1blk, i2c, mipi, usb etc. However, it gets disabled as an unused clock at boot-up. This can lead to failures in operation of above blocks, because they can not be configured properly if this clock is disabled.
