I'd use __CDNS_DSI_H or __CDNS_DSI_H__, it's customary to prefix header
guards with __ (don't forget to update the one at the end of the file).

Include linux/bits.h for BIT() and GENMASK() and linux/completion.h for
struct completion.

> +#include <linux/phy/phy.h>
> +#include <linux/phy/phy-mipi-dphy.h>

This header file isn't needed here, you can keep it in cdns-dsi-core.c.

None of the above macros are used in
drivers/gpu/drm/bridge/cadence/cdns-dsi-j721e.c in patch 5/5, so I would
keep them in the .c file to minimize changes.

Missing forward declarations:

struct clk;
struct reset_control;

I would also add

struct drm_panel;

(in alphabetical order) and drop inclusion of drm_panel.h.
