When enabling CONFIG_DISPLAY_ROCKCHIP_HDMI, compile-time warning for
the following implicitly defined functions are raised due to a missing
include directive:
drivers/video/rockchip/rk_hdmi.c: In function 'rk_hdmi_probe':
drivers/video/rockchip/rk_hdmi.c:150:2: warning: implicit declaration of
function 'rk_setreg' [-Wimplicit-function-declaration]
rk_setreg(&priv->grf->soc_con6, 1 << 15);
^~~~~~~~~
drivers/video/rockchip/rk_hdmi.c:153:2: warning: implicit declaration of
function 'rk_clrsetreg' [-Wimplicit-function-declaration]
rk_clrsetreg(&priv->grf->soc_con6, 1 << 4,
^~~~~~~~~~~~
This change fixes this by including <asm/hardware.h> in rk_hdmi.c.
