/* Initialize detected SPI and I2C bus and devices */
Update helpers and drivers to handle LVGLv7 and v8 versions (#161) * [lvgl_helpers] Cleanup and misc code cleanup Checks for SPI_HOST_MAX symbol before using it. Rename lvgl_driver_init to lvgl_interface_init because it now only initialize the interface bus for display drivers, we still need to remove the indev drivers from here. Use types defined in spi_types.h for spi host (spi_host_device_t) and spi dma channels (spi_dma_chan_t). Also add a couple of symbols to avoid using magic numbers * [lvgl_helpers] Reduce usage of if defined in lvgl_interface_init * [lvgl_helpers] Fix spi dma channel for ESP-IDF versions <= 4.2 * [examples] Update hello_world to call lvgl_interface_init * Add lvgl_get_display_buffer_size helper This helper will allow us to get the calculated display buffer size instead of using a global symbol. * Implement lvgl_get_display_buffer_size This API will be used to get the calculation of display buffer size. * Delete DISP_BUF_SIZE symbols The same functionality is handled by lvgl_get_display_buffer_size * Move SPI max transfer size calculation to helper Use calculate_spi_max_transfer_size to calculate the SPI max transfer size for the SPI master configuration * Remove SPI_BUS_MAX_TRANSFER_SZ definition Same functionality is now handled in calculate_spi_max_transfer_size * Update display buffer size calculation Use lvgl_get_display_buffer_size helper instead of DISP_BUF_SIZE symbol * Update example to LVGL v8 Add comments about changes from: - LVGL v7 to LVGL v8 - Configuration helpers and display drivers * Update lvgl_helpers.c * Update sh1107 driver * Update EVE driver Check for symbols used in previous implementations before trying to use them and add a fallback temporary implementation when not found.

/* Initialize SPI master */
Cleanup lvgl_helpers (#171) * lvgl_spi_conf: Define TFT_SPI_HOST even when no SPI is choosen * lvgl_helpers: Let the SPI driver choose SPI DMA Channel Use SPI_DMA_CH1 only on ESP32 target. * lvgl_helpers: Move FT81X initialization to helper * lvgl_interface_init: Initial cleanup * lvgl_helpers: Replace spi_common_dma_t values with integers This enum was introduced in ESP-IDF v4.3 and can't be used in older versions of ESP-IDF. * lvgl_helpers: Rearrange includes * lvgl_tft: Remove gpio_pad_select_gpio from drivers init functions * lvgl_helpers: Use spi_host_device_t from v4.3 onwards * esp_backlight: Replace gpio with esp_rom API * il3820: Remove GPIO initialization from driver init * FT81x: Replace gpio_pad_select_gpio with esp_rom alias * Fix esp_rom_gpio.h path * FT81x: Fix esp_rom_gpio.h path * adcraw: Disable usage of gpio_pad_select_gpio * GC9A01: Remove usage of gpio_pad_select_gpio * ra8875: Remove usage of gpio_pad_select_gpio * Revert "esp_backlight: Replace gpio with esp_rom API" This reverts commit 24e4bf0b888e68f09bcf1b900afa41ef76db2371. * Revert "FT81x: Replace gpio_pad_select_gpio with esp_rom alias" This reverts commit 8c7bc4214012b4b08854d07751a47836c5738d99. * esp_lcd_backlight: Handle different versions of ESP-IDF * esp_lcd_backlight: Add missing header * lvgl_spi_conf: Add missing include * uc8151d/jd79653a: Fix compilation error when logging is enabled * FT81x: Handle ESP-IDF v4.3 rom_gpio * FT81x: Add missing include * Compilation error when SPI Host is not selected * lvgl_helpers.c: Enable init_ft81x only when FT81X is selected * adcraw: Handle gpio_pad_selection on multiple ESP-IDF versions * esp_lcd_backlight: Remove esp_rom functions * FT81x: Remove esp_rom functions * adcraw: Remove esp_rom functions
