Subject: [PATCH 0/3] drm/rockchip: avoid overflow of clock rate

This patchset fixes conversion of the clock frequency from kHz to Hz in
Rockchip DRM driver to avoid potential integer overflow on 64-bit arches
(it is not possible to avoid on 32-bit arches due to the clk API using
'unsigned long' for the clock frequency).

Karina Yankevich (3):
  drm/rockchip: vop: avoid overflow of clock rate in
    vop_crtc_mode_fixup()
  drm/rockchip: vop: avoid overflow of clock rate in
    vop_crtc_atomic_enable()
  drm/rockchip: dw_hdmi: avoid overflow of clock rate in
    dw_hdmi_rockchip_encoder_mode_set()
