### Description / Steps to reproduce the issue Enabling the SPI driver within the Kconfig, gives you the ability to set either the CS or MISO pins to -1 in case they're not used by the board. <img width="1356" height="352" alt="Image" src="https://github.com/user-attachments/assets/62671a77-bd0f-4c72-a151-28c4936fb1e7"; /> However, the SPI Device hardware configuration has them defined as `uint8_t`, thus completely disabling this feature. See the snippet below: ```c /* arch/xtensa/src/esp32s3/esp32s3_spi.c, line 118 */ /* SPI Device hardware configuration */ struct esp32s3_spi_config_s { uint32_t clk_freq; /* SPI default clock frequency */ uint32_t width; /* SPI default width */ enum spi_mode_e mode; /* SPI default mode */ uint8_t id; /* ESP32-S3 SPI device ID: SPIx {2,3} */ uint8_t cs_pin; /* GPIO configuration for CS */ uint8_t mosi_pin; /* GPIO configuration for MOSI */ uint8_t miso_pin; /* GPIO configuration for MISO */ uint8_t clk_pin; /* GPIO configuration for CLK */ #ifdef CONFIG_ESP32S3_SPI_DMA uint8_t periph; /* Peripheral ID */ uint8_t irq; /* Interrupt ID */ #endif uint32_t clk_bit; /* Clock enable bit */ uint32_t rst_bit; /* SPI reset bit */ #ifdef CONFIG_ESP32S3_SPI_DMA uint32_t dma_clk_bit; /* DMA clock enable bit */ uint32_t dma_rst_bit; /* DMA reset bit */ uint8_t dma_periph; /* DMA peripheral */ #endif uint32_t cs_insig; /* SPI CS input signal index */ uint32_t cs_outsig; /* SPI CS output signal index */ uint32_t mosi_insig; /* SPI MOSI input signal index */ uint32_t mosi_outsig; /* SPI MOSI output signal index */ uint32_t miso_insig; /* SPI MISO input signal index */ uint32_t miso_outsig; /* SPI MISO output signal index */ uint32_t clk_insig; /* SPI CLK input signal index */ uint32_t clk_outsig; /* SPI CLK output signal index */ }; ``` Simply changing both ``cs_pin`` and ``miso_pin`` to ``int16_t`` resolves the issue, while still counting high number of GPIOs (>127) ### On which OS does this issue occur?
