From: Kartik Rajput <kkartik@xxxxxxxxxx> [ Upstream commit 836b341cc8dab680acc06a7883bfeea89680b689 ] Various Nvidia userspace applications and tests access following fuse via Fuse nvmem interface: * odmid * odminfo * boot_security_info * public_key_hash * reserved_odm0 * reserved_odm1 * reserved_odm2 * reserved_odm3 * reserved_odm4 * reserved_odm5 * reserved_odm6 * reserved_odm7 * odm_lock * pk_h1 * pk_h2 * revoke_pk_h0 * revoke_pk_h1 * security_mode * system_fw_field_ratchet0 * system_fw_field_ratchet1 * system_fw_field_ratchet2 * system_fw_field_ratchet3 * optin_enable Update tegra234_fuse_keepouts list to allow reading these fuse from nvmem sysfs interface.
