* tpm/st33zp24/spi: Add missing device table for spi phy.Christophe Ricard2015-03-26

* tpm/st33zp24: Add proper wait for ordinal duration in case of irq modeChristophe Ricard2015-03-26
| | | | | | | | | | | | | | In case the driver is configured to use irq, we are not waiting the answer for a duration period to see the DATA_AVAIL status bit to raise but at maximum timeout_c. This may result in critical failure as we will not wait long enough for the command completion.

* tpm/tpm_i2c_stm_st33: Split tpm_i2c_tpm_st33 in 2 layers (core + phy)Christophe Ricard2015-03-18
tpm_i2c_stm_st33 is a TIS 1.2 TPM with a core interface which can be used by different phy such as i2c or spi. The core part is called st33zp24 which is also the main part reference. include/linux/platform_data/tpm_stm_st33.h is renamed consequently. The driver is also split into an i2c phy in charge of sending/receiving data as well as managing platform data or dts configuration.
