Both HDMI/DP and PHY patch set depend on each other to pass build. HDMI driver depend on phy-hdmi.h and PHY driver depend on cdns-mhdp-mailbox.h to pass build. The followed description had in cover patch: "The patch set compose of DRM bridge drivers and PHY drivers. Both of them need the followed two patches to pass build. drm: bridge: cadence: convert mailbox functions to macro functions phy: Add HDMI configuration options" > > > > > Signed-off-by: Sandor Yu <Sandor.yu@nxp.com> > > --- > > include/linux/phy/phy-hdmi.h | 33 > +++++++++++++++++++++++++++++++++ > > include/linux/phy/phy.h | 7 ++++++- > > 2 files changed, 39 insertions(+), 1 deletion(-) create mode 100644 > > include/linux/phy/phy-hdmi.h > > > > diff --git a/include/linux/phy/phy-hdmi.h > > b/include/linux/phy/phy-hdmi.h new file mode 100644 index > > 000000000000..73a32eb535b0 > > --- /dev/null > > +++ b/include/linux/phy/phy-hdmi.h > > @@ -0,0 +1,33 @@ > > +/* SPDX-License-Identifier: GPL-2.0 */ > > +/* > > + * Copyright 2022 NXP > > + */ > > + > > +#ifndef __PHY_HDMI_H_ > > +#define __PHY_HDMI_H_ > > + > > +enum hdmi_phy_colorspace { > > + HDMI_PHY_COLORSPACE_RGB, > > + HDMI_PHY_COLORSPACE_YUV422, > > + HDMI_PHY_COLORSPACE_YUV444, > > + HDMI_PHY_COLORSPACE_YUV420, > > + HDMI_PHY_COLORSPACE_RESERVED4, > > + HDMI_PHY_COLORSPACE_RESERVED5, > > + HDMI_PHY_COLORSPACE_RESERVED6, > > +}; > > kernel-doc style comments here too please OK, I will add it. > > > + > > +/** > > + * struct phy_configure_opts_hdmi - HDMI configuration set > > + * @pixel_clk_rate: Pixel clock of video modes in KHz. > > + * @bpc: Maximum bits per color channel. > > + * @color_space: Colorspace in enum hdmi_phy_colorspace. > > + * > > + * This structure is used to represent the configuration state of a HDMI phy. > > + */ > > +struct phy_configure_opts_hdmi { > > + unsigned int pixel_clk_rate; > > + unsigned int bpc; > > + enum hdmi_phy_colorspace color_space; }; > > + > > +#endif /* __PHY_HDMI_H_ */ > > diff --git a/include/linux/phy/phy.h b/include/linux/phy/phy.h index > > b1413757fcc3..6f6873ea7270 100644 > > --- a/include/linux/phy/phy.h > > +++ b/include/linux/phy/phy.h > > @@ -17,6 +17,7 @@ > > #include <linux/regulator/consumer.h> > > > > #include <linux/phy/phy-dp.h> > > +#include <linux/phy/phy-hdmi.h> > > #include <linux/phy/phy-lvds.h> > > #include <linux/phy/phy-mipi-dphy.h> > > > > @@ -42,7 +43,8 @@ enum phy_mode { > > PHY_MODE_MIPI_DPHY, > > PHY_MODE_SATA, > > PHY_MODE_LVDS, > > - PHY_MODE_DP > > + PHY_MODE_DP, > > + PHY_MODE_HDMI, > > }; > > > > enum phy_media { > > @@ -60,11 +62,14 @@ enum phy_media { > > * the DisplayPort protocol. > > * @lvds: Configuration set applicable for phys supporting > > * the LVDS phy mode. > > + * @hdmi: Configuration set applicable for phys supporting > > + * the HDMI phy mode. > > */ > > union phy_configure_opts { > > struct phy_configure_opts_mipi_dphy mipi_dphy; > > struct phy_configure_opts_dp dp; > > struct phy_configure_opts_lvds lvds; > > + struct phy_configure_opts_hdmi hdmi; > > }; > > > > /** > > -- > > 2.34.1 > > -- > ~Vinod B.R Sandor
