support esp32-p4 guiton?

[NickyDark1]

I have this device that I want to use with MicroPython. Is there already support for it? How would I build the binaries for this device?

If possible, I could help if it's working on the ESP32 Guiton.

You can first modify the code according to #515, so that the code can fix the support for DSI driver, then compile, and then your screen will be ST7701. Find the corresponding driver and modify it according to the linked code.

Parameters such as hsync _ back _ porch, hsync _ pulse _ width, hsync _ front _ porch, vsync _ back _ porch, vsync _ pulse _ width, vsync _ front _ porch, etc. are modified according to the following code (extracted from https://github.com/NickyDark1/esp32_p4_jc4880p433c_bsp):

        .dpi_clk_src = MIPI_DSI_DPI_CLK_SRC_DEFAULT,
        .dpi_clock_freq_mhz = CONFIG_BSP_JC4880P443C_DPI_CLOCK_MHZ,

            help
                MIPI DSI lane bitrate in Mbps. Higher values support faster refresh rates
                but may cause signal integrity issues. 500 Mbps is recommended for this panel.

        config BSP_JC4880P443C_DPI_CLOCK_MHZ
            int "DPI clock frequency (MHz)"
            default 34
            range 20 100
            help
                DPI (Display Pixel Interface) clock frequency in MHz.
                This affects the refresh rate. 34 MHz gives ~60Hz refresh rate.
