We are setting the bit for gpio_tier1_sci_en from the ASL code as OS clears this bit if set from BIOS. As per ACPI spec _GPE is defined as the Named Object that evaluates to either an integer or a package.

There is a second ACPI _DSD document from the UEFI Forum that details how _DSD style tables can be nested, creating a tree of similarly formatted tables. This document is linked from acpi_device.h. In order to support this the device property interface needs to be more flexible and build up a tree of properties to write all entries at once instead of writing each entry as it is generated. In the end this is a more flexible solution that can support drivers that need child tables like the DA7219 codec, while only requiring minor changes to the existing drivers that use the device property interface. This was tested on reef (apollolake) and chell (skylake) boards to ensure that there was no change in the generated SSDT AML.

2016-07-02soc/intel/apollolake: handle p2sb quirksAaron Durbin
The P2SB device is device 0xd and function 0. If hidden that causes the latter pci devices on function >= 1 to not be probed in the kernel. This is also a problem for coreboot if the P2SB device is hidden by FSP. That means the coreboot driver won't be ran. Therefore, provide hide and unhide functions for the P2SB device. The other quirk is to allow the GPIO devices to work correctly. Those devices are ACPI devices. However, their resources are sub-regions within the P2SB BAR. Sadly, linux doesn't handle ACPI devices being children of PCI devices. This leads to resource conflict errors when the P2SB device is visible. For the time being keep the P2SB device hidden, but also ensure the resources it is using are accounted for and reserved. The fallout of that is the PMC and SPI device are no longer probed by the kernel.

If there is an external 16550 like UART, one needs to enable the appropriate address ranges before console_init() is called so that the init sequence can reach the external UART. Otherwise the UART will only start working in ramstage and will produce unreadable characters in romstage due to the lack of initialization.

2016-06-21lpss_i2c: Set SDA hold and support custom speed configDuncan Laurie
This I2C controller has separate registers for different speeds to set specific timing for SCL high and low times, and then a single register to configure the SDA hold time. For the most part these values can be generated based on the freq of the controller clock, which is SOC-specific. The existing driver was generating SCL HCNT/LCNT values, but not the SDA hold time so that is added. Additionally a board may need custom values as the exact timing can depend on trace lengths and the number of devices on the I2C bus. This is a two-part customizaton, the first is to set the values for desired speed for use within firmware, and the second is to provide those values in ACPI for the OS driver to consume. And finally, recent upstream changes to the designware i2c driver in the Linux kernel now support passing custom timing values for high speed and fast-plus speed, so these are now supported as well. Since these custom speed configs will come from devicetree a macro is added to simplify the description: register "i2c[4].speed_config" = "{ LPSS_I2C_SPEED_CONFIG(STANDARD, 432, 507, 30), LPSS_I2C_SPEED_CONFIG(FAST, 72, 160, 30), LPSS_I2C_SPEED_CONFIG(FAST_PLUS, 52, 120, 30), LPSS_I2C_SPEED_CONFIG(HIGH, 38, 90, 30), }" Which will result in the following speed config in \_SB.PCI0.I2C4: Name (SSCN, Package () { 432, 507, 30 }) Name (FMCN, Package () { 72, 160, 30 }) Name (FPCN, Package () { 52, 120, 30 }) Name (HSCN, Package () { 38, 90, 30 }) Change-Id: I18964426bb83fad0c956ad43a36ed9e04f3a66b5 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15163 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-06-09skylake: Support common LPSS I2C driverDuncan Laurie
Support the common Intel LPSS I2C driver for the 6 I2C bus controllers that are present on the Skylake-LP PCH with a 120 mHz clock. The required lpss_i2c_base_address() method is implemented separately for verstage/romstage and ramstage environments. This provides methods to convert to and from "struct device" and the I2C controller bus number for that device. These are used to provide support for the "I2C Bus Operations" that are present in the coreboot devicetree. To support the I2C controller before ramstage an early init function is provided to do minimal initializaiton of the PCI device and assign a temporary base address for use before memory. The final base address is assigned during device enumeration and used during ramstage. Because it is usually not necessary to enable I2C controllers before ramstage a config register for the devicetree is provided to perform early initialization of this controller. In addition the bus speed can be set in the devicetree and that speed will be applied when the device is initialized. If not provided the default speed is set to I2C_SPEED_FAST. This was tested with the google/chell mainboard by reading and writing from the trackpad and codec devices during both verstage and ramstage.

Add the voltage tolerance GPIO attribute for configuring I2C/I2S buses that are at 1.8V. This is currently done by passing in a value to FSP but it is needed earlier than FSP if the I2C bus is used in verstage. This does not remove the need for the FSP input parameter, that is still required so FSP doesn't disable what has been set in coreboot. The mainboards that are affected are updated in this commit. This was tested by exercising I2C transactions to the 1.8V codec while in verstage on the google/chell mainboard.

2016-06-09soc/intel/common: Add LPSS I2C driverDuncan Laurie
Add a generic LPSS I2C driver for Intel SOCs that use the Synopsys DesignWare I2C block and have a similar configuration of that block. This driver is ported from the Chromium depthcharge project where it was ported from U-Boot originally, though it looks very different now. From depthcharge it has been modified to fit into the coreboot I2C driver model with platform_i2c_transfer() and use coreboot semantics throughout including the stopwatch API for timeouts. In order for this shared driver to work the SOC must: 1) Define CONFIG_SOC_INTEL_COMMON_LPSS_I2C_CLOCK_MHZ to set the clock speed that the I2C controller core is running at. 2) Define the lpss_i2c_base_address() function to return the base address for the specified bus. This could be either done by looking up the PCI device or a static table if the controllers are not PCI devices and just have a static base address. The driver is usable in verstage/romstage/ramstage, though it does require early initialization of the controller to set a temporary base address if it is used outside of ramstage. This has been tested on Broadwell and Skylake SOCs in both pre-RAM and ramstage environments by reading and writing both single bytes across multiple segments as well as large blocks of data at once and with different configured bus speeds. While it does need specific configuration for each SOC this driver should be able to work on all Intel SOCs currently in src/soc/intel.
