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. The falback implementation isn't tested with hardware.
