2013-10-22tpm: Add support for Atmel I2C TPMsJason Gunthorpe1-0/+9
This is based on the work of Teddy Reed <teddy@prosauce.org> published on GitHub: https://github.com/theopolis/tpm-i2c-atmel.git 34894b988b67e0ae55088d6388e77b0dbf10c07d That driver was never merged, I have taken it as a starting port, forward ported, tested and revised the driver: - Make it broadly textually similar to the Infineon and Nuvoton I2C driver - Place everything in a format suitable for mainline inclusion - Use high level I2C functions i2c_master_send and i2c_master_recv for data xfer - Use the timeout system from the core code, by faking out a status register - Only I2C transfer the number of bytes in the reply, not a fixed message size. - checkpatch cleanups - Testing on ARM Kirkwood, with this device tree, using a AT97SC3204T-X1A180 tpm@29 { compatible = "atmel,at97sc3204t"; reg = <0x29>; }; Signed-off-by: Teddy Reed <teddy@prosauce.org> [jgg: revised and tested] Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> [phuewe: minor whitespace changes] Signed-off-by: Peter Huewe <peterhuewe@gmx.de>
2013-10-22tpm: Add support for the Nuvoton NPCT501 I2C TPMJason Gunthorpe1-0/+10
This chip is/was also branded as a Winbond WPCT301. Originally written by Dan Morav <dmorav@nuvoton.com> and posted to LKML: https://lkml.org/lkml/2011/9/7/206 The original posting was not merged, I have taken it as a starting point, forward ported, tested and revised the driver: - Rework interrupt handling to work properly with level triggered interrupts. The old version just locked up. - Synchronize various items with Peter Huewe's Infineon driver: * Add durations/timeouts sysfs calls * Remove I2C device auto-detection * Don't fiddle with chip->release * Call tpm_dev_vendor_release in the probe error path * Use MODULE_DEVICE_TABLE for the I2C ids * Provide OF compatible strings for DT support * Use SIMPLE_DEV_PM_OPS * Use module_i2c_driver - checkpatch cleanups - Testing on ARM Kirkwood with GPIO interrupts, with this device tree: tpm@57 { compatible = "nuvoton,npct501"; reg = <0x57>; interrupt-parent = <&gpio1>; interrupts = <6 IRQ_TYPE_LEVEL_LOW>; }; Signed-off-by: Dan Morav <dmorav@nuvoton.com> [jgg: revised and tested] Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> [phuewe: minor whitespace changes, fixed module name in kconfig] Signed-off-by: Peter Huewe <peterhuewe@gmx.de>

2012-08-22drivers/char/tpm: Add new device driver to support IBM vTPMAshley Lai1-0/+8
This patch adds a new device driver to support IBM virtual TPM (vTPM) for PPC64. IBM vTPM is supported through the adjunct partition with firmware release 740 or higher. With vTPM support, each lpar is able to have its own vTPM without the physical TPM hardware. This driver provides TPM functionalities by communicating with the vTPM adjunct partition through Hypervisor calls (Hcalls) and Command/Response Queue (CRQ) commands.

2012-08-22char/tpm: Add new driver for Infineon I2C TIS TPMPeter Huewe1-0/+11
This patch adds a driver to support Infineon's SLB 9635 TT 1.2 Soft I2C TPMs which follow the TGC TIS 1.2 TPM specification[1] and Infineon's I2C Protocol Stack Specification 0.20. The I2C Protocol Stack Specification is a simple adaption of the LPC TIS Protocol to the I2C Bus. The I2C TPMs can be used when LPC Bus is not available (i.e. non x86 architectures like ARM). The driver is based on the tpm_tis.c driver by Leendert van Dorn and Kyleen Hall and has quite similar functionality. Tested on Nvidia ARM Tegra2 Development Platform and Beagleboard (ARM OMAP) Tested with the Trousers[2] TSS API Testsuite v 0.3 [3] Compile-tested on x86 (32/64-bit) Updates since version 2.1.4: - included "Lock the I2C adapter for a sequence of requests", by Bryan Freed - use __i2c_transfer instead of own implementation of unlocked i2c_transfer - use struct dev_pm_ops for power management via SIMPLE_DEV_PM_OPS Updates since version 2.1.3: - use proper probing mechanism * either add the tpm using I2C_BOARD_INFO to your board file or probe it * during runtime e.g on BeagleBoard using : * "echo tpm_i2c_infineon 0x20 > /sys/bus/i2c/devices/i2c-2/new_device" - fix possible endless loop if hardware misbehaves - improved return codes - consistent spelling i2c/tpm -> I2C/TPM - remove hardcoded sleep values and msleep usage - removed debug statements - added check for I2C functionality - renaming to tpm_i2c_infineon Updates since version 2.1.2: - added sysfs entries for duration and timeouts - updated to new tpm_do_selftest Updates since version 2.1.0: - improved error handling - implemented workarounds needed by the tpm - fixed typos References: [1] http://www.trustedcomputinggroup.org/resources/pc_client_work_group_pc_client_ specific_tpm_interface_specification_tis_version_12/ [2] http://trousers.sourceforge.net/ [3] http://sourceforge.net/projects/trousers/files/TSS%20API%20test%20suite/0.3/ Reviewed-by: Andi Shyti <andi.shyti@gmail.com> Acked-by: Marcel Selhorst <tpmdd@selhorst.net> Signed-off-by: Peter Huewe <peter.huewe@infineon.com> Signed-off-by: Bryan Freed <bfreed@chromium.org> Signed-off-by: Kent Yoder <key@linux.vnet.ibm.com>

2011-09-23TPM: TCG_ATMEL should depend on HAS_IOPORTGeert Uytterhoeven1-0/+1
On m68k, I get: drivers/char/tpm/tpm_atmel.h: In function ‘atmel_get_base_addr’: drivers/char/tpm/tpm_atmel.h:129: error: implicit declaration of function ‘ioport_map’ drivers/char/tpm/tpm_atmel.h:129: warning: return makes pointer from integer without a cast The code in tpm_atmel.h supports PPC64 (using the device tree and ioremap()) and "anything else" (using ioport_map()). However, ioportmap() is only available on platforms that set HAS_IOPORT. Although PC64 seems to have HAS_IOPORT, a "depends on HAS_IOPORT" should work, but I think it's better to expose the special PPC64 handling explicit using "depends on PPC64 || HAS_IOPORT".

This patch pushes the ACPI dependency into the device driver code itself. Now, even without ACPI/PNP enabled, the device can be registered using the TIS specified memory space.

2008-04-29tpm: change Kconfig dependencies from PNPACPI to PNPBjorn Helgaas1-3/+2
There is no "PNPACPI" driver interface as such. PNPACPI is an internal backend of PNP, and drivers just use the generic PNP interface. The drivers should depend on CONFIG_PNP, not CONFIG_PNPACPI. tpm_nsc.c doesn't use PNP at all, so we can just remove the dependency completely. It probably *should* use PNP to discover the device, but until it does, there's no point in depending on PNP.

2005-08-05[PATCH] tpm_infineon: Support for new TPM 1.2 and PNPACPIMarcel Selhorst1-4/+7
This patch includes support for the new Infineon Trusted Platform Module SLB 9635 TT 1.2 and does further include ACPI-support for both chip versions (SLD 9630 TT 1.1 and SLB9635 TT 1.2). Since the ioports and configuration registers are not correctly set on some machines, the configuration is now done via PNPACPI, which reads out the correct values out of the DSDT-table. Note that you have to have CONFIG_PNP, CONFIG_ACPI_BUS and CONFIG_PNPACPI enabled to run this driver (assuming that mainboards including a TPM do have the need for ACPI anyway).

This patch provides a new device driver for the Infineon SLD 9630 TT Trusted Platform Module (TPM 1.1b) [1] which is embedded on Intel- mainboards or in HP/ Fujitsu-Siemens / Toshiba-Notebooks. A nearly complete list where this module is integrated in can be found in [2]. This kernel module acts as a communication gateway between the linux kernel and the hardware chip and fits the TPM-specific interfaces created by IBM in drivers/char/tpm/tpm.h Further information about this module and a list of succesfully tested and therefore supported hardware can be found at our project page [3].

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
