| Subject: clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg clock |
| |
| From: Abhilash Kesavan <a.kesavan@samsung.com> |
| |
| 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. |
