Loongson security engine supports random number generation, hash,
symmetric encryption and asymmetric encryption. Based on these
encryption functions, TPM2 have been implemented in it.

mfd is the baser driver, crypto and tpm are users.

v4: Please look at changelog in tpm and MAINTAINERS. No changes to tpm
    and crypto. 
v3: Put the updates to the MAINTAINERS in a separate patch.
v2: Removed misc driver. Added tpm driver.

Qunqin Zhao (6):
  mfd: Add support for Loongson Security Module
  MAINTAINERS: Add entry for Loongson Security Module driver
  crypto: loongson - add Loongson RNG driver support
  MAINTAINERS: Add entry for Loongson RNG driver
  tpm: Add a driver for Loongson TPM device
  MAINTAINERS: Add tpm_lsse.c to LOONGSON CRYPTO DRIVER entry

Loongson SE should not strongly bound to LS6000, so the naming can be improved:

MFD_LS6000SE -> MFD_LOONGSON_SE,  ls6000se.c -> loongson-se.c
CRYPTO_DEV_LS6000SE_RNG -> CRYPTO_DEV_LOONGSON_RNG,  ls6000se-rng.c ->
loongson-rng.c
TCG_LSSE -> TCG_LOONGSON, tpm_lsse.c ->tpm_loongson.c
