TWIM peripherals cannot perform write transactions from buffers located in flash. The content of such buffers needs to be copied to RAM before the actual transfer can be requested. This commits adds a new property (zephyr,flash-buf-max-size) that informs the driver how much space in RAM needs to be reserved for such copying and adds proper handling of buffers located in flash. This fixes an issue that caused that e.g. the DPS310 sensor driver did not work on nRF SoCs that only have TWIM, not TWI peripherals. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no> |
