Subject: [PATCH 056/113] FROMLIST(v4): drm/rockchip: dw_hdmi_qp: Provide ref
|
|
clock rate in dw_hdmi_qp_plat_data
|
|
|
|
In order to support correct initialization of the timer base in the HDMI
|
|
QP IP block, setup platform data to include the required reference clock
|
|
rate.
|
|
|
|
While at it, ensure plat_data is zero-initialized in
|
|
dw_hdmi_qp_rockchip_bind().
