Hi, Qunqin,
Where is the 2nd patch in V7?
Hi, Huacai
I added "loongson se. c" and "loongson se. h" to the LOONGSON CRYPTO
DRIVER entry.
or should i add a separate entry for the mfd driver as done in v7?
Thanks for your comments,
Qunqin.

The Loongson Security Engine chip supports RNG, SM2, SM3 and SM4
accelerator engines. Each engine have its own DMA buffer provided
by the controller. The kernel cannot directly send commands to the
engine and must first send them to the controller, which will
forward them to the corresponding engine. Based on these engines,
TPM2 have been implemented in the chip, then let's treat TPM2 itself
as an engine.
v9: Moved the base driver back to drivers/mfd. Cleanned up coding style.
v8: Like Lee said, the base driver goes beyond MFD scope. Since these
are all encryption related drivers and SM2, SM3, and SM4 drivers
will be added to the crypto subsystem in the future, the base driver
need to be changed when adding these drivers. Therefore, it may be
more appropriate to place the base driver within the crypto
subsystem.
Removed complete callback in all drivers. Removed the concepts of
"channel", "msg" and "request" as they may be confusing. Used the
concepts of "egnine" and "command" may be better.
v7: Addressed Huacai's comments.
v6: mfd :MFD_LS6000SE -> MFD_LOONGSON_SE, ls6000se.c -> loongson-se.c
crypto :CRYPTO_DEV_LS6000SE_RNG -> CRYPTO_DEV_LOONGSON_RNG,
ls6000se-rng.c ->loongson-rng.c
tpm: TCG_LSSE -> TCG_LOONGSON, tpm_lsse.c ->tpm_loongson.c
v5: Registered "ls6000se-rng" device in mfd driver
Qunqin Zhao (5):
mfd: Add support for Loongson Security Engine chip controller
crypto: loongson - add Loongson RNG driver support
MAINTAINERS: Add entry for Loongson crypto driver
tpm: Add a driver for Loongson TPM device
MAINTAINERS: Add tpm_loongson.c to LOONGSON CRYPTO DRIVER entry
