2016-06-23tpm2: add SPI TPM driverVadim Bendebury
This introduces a SPI TPM driver compliant with the TCG issued "TPM Profile (PTP) Specification Revision 00.43" which can be found by googling its title. The driver implements both the hardware flow control protocol and the TPM state machine. The hardware flow control allows to map SPI based TPM devices to the LPC address space on x86 platforms, on all other platforms it needs to be implemented in the driver software. The tis layer is somewhat superficial, it might have to be expanded later. A lot more implementation details can be found in the code comments. Also, it is worth mentioning that this is not a complete version of the driver: its robustness needs to be improved, delay loops need to be bound, error conditions need to propagate up the call stack. BRANCH=none BUG=chrome-os-partner:52132, chrome-os-partner:50645, chrome-os-partner:54141 TEST=with the rest of the patches applied coreboot is able complete Chrome OS factory initialization of the TPM2 device.

2016-06-23kconfig: allow various tpm type and interface permutationsVadim Bendebury
Until now it was assumed that all TPM devices were of the same type (TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs and all other boards had I2C connected TPMs. With the advent of TPM2 specification there is a need to be able to configure different combinations of TPM types (TPM or TPM2) and interfaces (LPC, I2C and SPI). This patch allows to do it. Picking Chrome OS still assumes that the board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's Kconfig will trigger including of TPM2 instead. MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding SPI_TPM to the board config switches interface choice to SPI, and if neither of the two is defined, the interface is assumed to be I2C. BRANCH=none BUG=chrome-os-partner:50645 TEST=verified that none of the generated board configurations change as a result of this patch. With the rest of the stack in place it is possible to configure different combinations of TPM types and interfaces for ARM and x86 boards.

2016-06-02generic: Add a Maxim 98357A codec driverDuncan Laurie
The Maxim Integrated 98357A codec is an I2S slave device that has no control channel for configuration and instead provides a GPIO that is used for channel selection and power down. This means it does not fit into a bus hierarchy easily and is instead represented as a generic device and found with a static bus scan using the devicetree. This driver provides configuration options for passing the "sdmode" GPIO descriptor as well as a second option for "sdmode delay" which can configure the timing of the sdmode toggling in relation to the I2S channel output. In addition an GPIO can be provided to indicate to the driver whether this device is present or not. This can be used for board designs that may have different codec possibilities that are selected by HW strap. Sample usage for this device driver: device pci 1f.3 on chip drivers/generic/max98357a register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C6)" register "sdmode_delay" = "100" device generic 0 on end end end Will result in the following code in the SSDT: Scope (\_SB.PCI0.HDAS) { Device (MAXM) { Name (_HID, "MX98357A") Name (_UID, Zero) Name (_DDN, "Maxim Integrated 98357A Amplifier") Method (_STA) { Return (0xF) } Name (_CRS, ResourceTemplate () { GpioIo (Exclusive, PullDefault, 0, 0, IoRestrictionOutputOnly, "\\_SB.PCI0.GPIO", 0, ResourceConsumer) }) Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () { "maxim,sdmode-gpio", \_SB.PCI0.HDAS.MAXM, 0, 0, 0 } Package () { "maxim,sdmode-delay", 100 } Package () { "sdmode-delay", 100 } } }) } } Change-Id: Ia0bafe49bea9bbe4a3cc0f9f9cdb6f6390da57b5 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15017 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2016-06-02i2c: Add a generic i2c driverDuncan Laurie
This adds a generic I2C driver that can be described in the devicetree and used to generate ACPI objects in the SSDT based on the information provided in the config registers. The I2C bus can be configured and the device can provide an interrupt and wake capability to the OS. A configuration option allows for a GPIO to be provided that will be checked to determine if the device is preset on the board before including it in the generated SSDT. The driver is generic enough to be used for basic I2C devices that do not have special configuration needs such as touchpads, touchscreens, sensors, some audio codec/amplifiers, etc. Sample usage for a touchpad device: device pci 15.1 on chip drivers/i2c/generic register "hid" = ""ELAN0000"" register "desc" = "ELAN Touchpad" register "irq" = "IRQ_EDGE_LOW(GPP_B3_IRQ)" register "wake" = "GPE0_DW0_05" device i2c 15.0 on end end end Will result in the following code in the SSDT: Scope (\_SB.PCI0.I2C1) { Device (D015) { Name (_HID, "ELAN0000") Name (_UID, 0) Name (_S0W, 4) Name (_PRW, Package () { 5, 3 }) Method (_STA) { Return (0x0f) } Name (_CRS, ResourceTemplate () { I2cSerialBus (0x15, ControllerInitiated, 400000, AddressingMode7Bit, "\\_S.PCI0.I2C1", 0, ResourceConsumer) Interrupt (ResourceConsumer, Edge, ActiveLow) { 51 } }) } } Change-Id: Ib32055720835b70e91ede5e4028ecd91894d70d5 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15016 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
