Subject: About the SLB9670 TPM 2.0 driver status
Date: Tue, 25 Apr 2017 19:12:25 -0700 [thread overview]
Message-ID: <e7ee0491-3f29-5578-7cc4-af9c0a73dcb3@witekio.us> (raw)
Hello,
I am working with on Infineon SLB9670 TPM 2.0 on SPI.
How well is this chip supported in the mainline kernel?
I am currently using the linux-socfpga kernel (version 4.8.0; branch
socfpga-4.8) [1]
on which I applied the following patches from patchwork:
aacabbe0d5ec tpm_tis_spi: Add small delay after last transfer [2]
a4a011be786f tpm_tis_spi: Remove limitation of transfers to
MAX_SPI_FRAMESIZE bytes [3]
840157e08b2f tpm_tis_spi: Check correct byte for wait state indicator [4]
10cb31aec536 tpm_tis_spi: Abort transfer when too many wait states are
signaled [5]
3ad7d9172a8c tpm_tis_spi: Use single function to transfer data [6]
4a809ec34a0f tpm_tis_core: Choose appropriate timeout for reading
burstcount [7]
With these patches, I can read the Vendor ID properly.
But, the driver initialization fails in the tpm2_probe function.
Did I miss an important patch?
Regards,
Georges
