This series adds support for the CDN DP controller to the rockchip drm driver. This version fixes some coding style error in v16, it post by Sean Paul, you can find it here: https://patchwork.kernel.org/patch/9442135/
And I sorted out a few patches to fix the following problems: - suspend/resume crash cause by drm_helper_hpd_irq_event - crash during shutdown when cdn-dp failed to bind - check sink count failed after reconnection - suspend/reusme crash in mode_set function
I also added these 2 patches to this series, although nothing changed: https://patchwork.kernel.org/patch/9442141/ https://patchwork.kernel.org/patch/9442151/
Changes in v17: - Correct the clock check condition - Correct the coding style - change LANE_REF_CYC to 0x8000
