2019-01-03sb/intel/lynxpoint/pcie.c: Add more checks for NULL pointersTristan Corrick
If PCIe root port `n` is disabled, then `rpc.ports[n - 1]` remains NULL. The existing Lynx Point systems probably don't end up dereferencing NULL pointers this way. However, it might occur on a system using Flexible I/O to remap PCIe root ports to other functions. Tested on an ASRock H81M-HDS and an Acer C720 (Google Peppy). No issues presented themselves.

2019-01-03sb/intel/lynxpoint: Remove incomplete SATA ACPI codeTristan Corrick
The existing SATA ACPI code for Lynx Point implements some methods and devices, but not completely. These methods are optional and only used in IDE mode. The code was likely copied from bd82x6x, where it has since been removed. As a result, many remarks produced by iasl about unreferenced objects are eliminated. Tested on an ASRock H81M-HDS and an Acer C720. No issues with SATA were observed.

2018-12-29nb/intel/haswell: Don't unconditionally set DEVENTristan Corrick
The existing code sets DEVEN with the intention of enabling the IGD and Mini-HD audio. However, according to the datasheet [1] and some testing on hardware, the bits in DEVEN are set by default if and only if the straps/fuses say the device should be enabled. To illustrate this, here are a few initial values of DEVEN on some Haswell systems: Supermicro X10SLM+-F: 0x0000002d ASRock H81M-HDS: 0x00000039 Acer C720: 0x000000b1 On the X10SLM+-F, the IGD is disabled by default, and PEG10 & PEG11 are enabled by default. On the C720, the PEG devices are all disabled by default, while the IGD and Mini-HD audio are already enabled. There are two issues that result from the existing behaviour: PEG devices are unconditionally disabled, and devices are set as enabled when it's not actually possible to enable them. So, don't touch the DEVEN register at this stage, as there are no benefits. Interestingly, on an Acer C720 (Google Peppy), a PCI device 00:04.0 appears. It is a thermal sensor. `powerstat` was used to measure idle power usage over 30 minutes under Debian GNU/Linux 9.6. There was no change in reported power draw.

2018-12-29nb/intel/haswell: Use DEVEN to disable devicesTristan Corrick
This allows devices to be properly disabled when they are set to `off` in the devicetree, or when a device has its `enabled` property set to false. A message is printed stating that a device is being disabled, even if it was already disabled via DEVEN. However, it could be useful to have this information, so such messages are kept. The device 00:04.0 is a thermal sensor on the Acer C720, but it has not been named as such in this patch. This is because the public datasheets never formally acknowledge what the device is, and how it might differ across platforms. Tested on a Supermicro X10SLM+-F. The Mini-HD audio is disabled now, silencing a warning from Linux. Also tested on an Acer C720 (Google Peppy). Disabling "device 4" from devicetree.cb works. Also tested on an ASRock H81M-HDS. For this device, and all other test devices, there were no regressions observed.

On some platforms SVI command completion is not reported by voltage regulator. Because of that CPU got stuck in invalid P-State, which resulted in lower frequency and inability to reboot platform without performing cold reset.

2018-12-28ec/chromeec: fix LPC read/write for MEC devicesMatt DeVillier
Commit 8cf8aa2 [ec/google/chromeec: Use common MEC interface] changed the return mechanism for the checksum on reads/writes for MEC devices, but incorrectly handled the passed-in csum parameter by not dereferencing. This led to the returned csum value always being zero, which causes all EC commands with non- NULL data_in to fail with a checksum error. Fix this by storing the returned checksum in a temp variable, and only assigning to csum when the pointer isn't NULL; Test: build/boot google/chell, verify EC hello command succeeds, keyboard backlight turned on at boot.
