2016-07-26meditek/mt8173: dsi: set mipi pin driving control onJitao Shi
We set this driving control to prevent signal attenuation caused by LVDS DRV termination. When DA_LVDSTX_PWR_ON is not set, LVSH has no power and LVDS DRV termination status is unknown (floating). This creates a chance that MIPI output would be influenced. The DSI's LP signal will be half voltage attenuation. There will be no display on panel. When DA_LVDSTX_PWR_ON is set, LVSH and LVDS DRV termination are effective and termination is fixed OFF. The DSI won't be influenced. We only need to set this register once, so we set it here to prevent repeatedly setting in the kernel when the system goes to recovery mode.

2016-07-12soc/intel/apollolake: Add handler for SCIShaunak Saha
This patch adds the handler to enable bit for gpio_tier1_sci_en. gpio_tier1_sci_en enables the setting of the GPIO_TIER1_SCI_STS bit to generate a wake event and/or an SCI or SMI#. 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. If _GPE evaluates to an integer, the value is the bit assignment of the SCI interrupt within the GPEx_STS register of a GPE block described in the FADT that the embedded controller will trigger. FADT right now has no mechanism to acheive the same.

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.

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.

Have the Skylake SOC generate ACPI timing values for the enabled I2C controllers instead of passing it in the DSDT with static timings.

Additionally it is now possible for a board to override the values using devicetree.cb. If zero is passed in for SCL HCNT or LCNT then the kernel will generate its own timing using the same forumla, but if the SDA hold time value is zero the kernel will NOT generate a correct value and the SDA hold time may be incorrect.
