This commit adds a driver for the Xaptum ENF Access Card, a TPM2.0 hardware module for authenticating IoT devices and gateways. The card consists of a SPI TPM 2.0 chip and a USB-SPI bridge. This driver configures the bridge, registers the bridge as an SPI controller, and adds the TPM 2.0 as an SPI device. The in-kernel TPM 2.0 driver is then automatically loaded to configure the TPM and expose it to userspace. Changes since v1: * Remove empty spi cleanup function * Fix __beXX/__eXX mismatches * Correct typos in comments * Add break to last case of switch * Check result of kzalloc David R.
