From 1259dcd79c70f97a1606b4b06190c8fa7a1810d1 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Thu, 21 Jan 2016 23:27:12 +0100 Subject: [PATCH] tpm: Rename tpm_tis_infineon.h to tpm_tis.h and move infineon specific stuff in tpm_infineon.c I2C protocol is not standardize for TPM 1.2. TIS prococol is define by the Trusted Computing Group and potentially available on several TPMs. tpm_tis_infineon.h header is not generic enough. Rename tpm_tis_infineon.h to tpm_tis.h and move infineon specific defines/variables to tpm_tis_infineon.c Reviewed-by: Simon Glass Signed-off-by: Christophe Ricard --- drivers/tpm/{tpm_tis_infineon.h => tpm_tis.h} | 17 +---------------- drivers/tpm/tpm_tis_infineon.c | 17 ++++++++++++++++- 2 files changed, 17 insertions(+), 17 deletions(-) rename drivers/tpm/{tpm_tis_infineon.h => tpm_tis.h} (86%) diff --git a/drivers/tpm/tpm_tis_infineon.h b/drivers/tpm/tpm_tis.h similarity index 86% rename from drivers/tpm/tpm_tis_infineon.h rename to drivers/tpm/tpm_tis.h index 3b510d101e..25b152b321 100644 --- a/drivers/tpm/tpm_tis_infineon.h +++ b/drivers/tpm/tpm_tis.h @@ -37,18 +37,12 @@ enum tpm_timeout { #define TPM_RSP_SIZE_BYTE 2 #define TPM_RSP_RC_BYTE 6 -enum i2c_chip_type { - SLB9635, - SLB9645, - UNKNOWN, -}; - struct tpm_chip { int is_open; int locality; u32 vend_dev; unsigned long timeout_a, timeout_b, timeout_c, timeout_d; /* msec */ - enum i2c_chip_type chip_type; + ulong chip_type; }; struct tpm_input_header { @@ -134,13 +128,4 @@ enum tis_status { TPM_STS_DATA_EXPECT = 0x08, }; -/* expected value for DIDVID register */ -#define TPM_TIS_I2C_DID_VID_9635 0x000b15d1L -#define TPM_TIS_I2C_DID_VID_9645 0x001a15d1L - -#define TPM_ACCESS(l) (0x0000 | ((l) << 4)) -#define TPM_STS(l) (0x0001 | ((l) << 4)) -#define TPM_DATA_FIFO(l) (0x0005 | ((l) << 4)) -#define TPM_DID_VID(l) (0x0006 | ((l) << 4)) - #endif diff --git a/drivers/tpm/tpm_tis_infineon.c b/drivers/tpm/tpm_tis_infineon.c index f57c32837b..a4b6741676 100644 --- a/drivers/tpm/tpm_tis_infineon.c +++ b/drivers/tpm/tpm_tis_infineon.c @@ -30,17 +30,32 @@ #include #include -#include "tpm_tis_infineon.h" +#include "tpm_tis.h" #include "tpm_internal.h" DECLARE_GLOBAL_DATA_PTR; +enum i2c_chip_type { + SLB9635, + SLB9645, + UNKNOWN, +}; + +/* expected value for DIDVID register */ +#define TPM_TIS_I2C_DID_VID_9635 0x000b15d1L +#define TPM_TIS_I2C_DID_VID_9645 0x001a15d1L + static const char * const chip_name[] = { [SLB9635] = "slb9635tt", [SLB9645] = "slb9645tt", [UNKNOWN] = "unknown/fallback to slb9635", }; +#define TPM_ACCESS(l) (0x0000 | ((l) << 4)) +#define TPM_STS(l) (0x0001 | ((l) << 4)) +#define TPM_DATA_FIFO(l) (0x0005 | ((l) << 4)) +#define TPM_DID_VID(l) (0x0006 | ((l) << 4)) + /* * tpm_tis_i2c_read() - read from TPM register * @addr: register address to read from -- 2.30.2
