Comparing to v5, this version only rebases the series upon v5.17-rc1. The Mixel PHY is MIPI DPHY + LVDS PHY combo, which can works in either MIPI DPHY mode or LVDS PHY mode. The PHY mode is controlled by i.MX8qxp SCU firmware. The PHY driver would call a SCU function to configure the mode. The PHY driver is already supporting the Mixel MIPI DPHY in i.MX8mq SoC, where it appears to be a single MIPI DPHY. Patch 1/5 sets PHY mode in the Northwest Logic MIPI DSI host controller bridge driver, since i.MX8qxp SoC embeds this controller IP to support MIPI DSI displays together with the Mixel PHY. Patch 2/5 allows LVDS PHYs to be configured through the generic PHY functions and through a custom structure added to the generic PHY configuration union. Patch 3/5 converts mixel,mipi-dsi-phy plain text dt binding to json-schema. Patch 4/5 adds dt binding support for the Mixel combo PHY in i.MX8qxp SoC. Patch 5/5 adds the i.MX8qxp LVDS PHY mode support in the Mixel PHY driver. Welcome comments, thanks. v5->v6: * Rebase the series upon v5.17-rc1. * Set PHY mode in ->mode_set() instead of ->pre_enable() in the nwl-dsi bridge driver in patch 1/5 due to the rebase. * Drop Guido's R-b tag on patch 1/5 due to the rebase. * Resend with linux-phy ML Cc'ed and reviewer mail addresses updated for patch 1/5. v4->v5: * Align kernel-doc style of include/linux/phy/phy-lvds.h to include/linux/phy/phy.h for patch 2/5. (Vinod) * Trivial tweaks on patch 2/5. * Drop Robert's R-b tag on patch 2/5. v3->v4: * Add all R-b tags received from v3 on relevant patches and respin. (Robert) v2->v3: * Improve readability of mixel_dphy_set_mode() in the Mixel PHY driver. (Guido) * Improve the 'clock-names' property in the PHY dt binding. v1->v2: * Convert mixel,mipi-dsi-phy plain text dt binding to json-schema. (Guido) * Print invalid PHY mode in dmesg from the Mixel PHY driver. (Guido) * Add Guido's R-b tag on the patch for the nwl-dsi drm bridge driver.
