mfd: intel-lpss: Pass SDA hold time to I2C host controller driver Intel Skylake the LPSS I2C pad circuit has internal delays that require programming non-zero SDA hold time for the I2C host controller. If this is not done communication to slave devices may fail with arbitration lost errors like the one seen below taken from Lenovo Yoga 900: i2c_hid i2c-SYNA2B29:00: Fetching the HID descriptor i2c_hid i2c-SYNA2B29:00: __i2c_hid_command: cmd=20 00 i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration To fix this we follow what the Windows driver is doing and pass the default SDA hold time of 230 ns to all Intel Skylake host controllers. This still allows the platform to override these values by passing special ACPI methods SSCN and FMCN.

mfd: intel-lpss: Fix I2C4 not being available on the Microsoft Surface Go & Go 2 Many DSDTs for Kaby Lake and Kaby Lake Refresh models contain a _SB.PCI0.GEXP ACPI Device node describing an I2C attached PCA953x GPIO expander. This seems to be something which is copy and pasted from the DSDT from some reference design since this ACPI Device is present even on models where no such GPIO expander is used at all, such as on the Microsoft Surface Go & Go 2. This ACPI Device is a problem because it contains a SystemMemory OperationRegion which covers the MMIO for the I2C4 I2C controller. This causes the MFD cell for the I2C4 controller to not be instantiated due to a resource conflict, requiring the use of acpi_enforce_resources=lax to work around this. I have done an extensive analysis of all the ACPI tables on the Microsoft Surface Go and the _SB.PCI0.GEXP ACPI Device's methods are not used by any code in the ACPI tables, neither are any of them directly called by any Linux kernel code. This is unsurprising since running i2cdetect on the I2C4 bus shows that there is no GPIO expander chip present on these devices at all. This commit adds a PCI subsystem vendor:device table listing PCI devices where it is known to be safe to ignore resource conflicts with ACPI declared SystemMemory regions. This makes the I2C4 bus work out of the box on the Microsoft Surface Go & Go 2, which is necessary for the cameras on these devices to work.

mfd: intel-lpss: Remove D3cold delay Goodix touchpad may drop its first couple input events when i2c-designware-platdrv and intel-lpss it connects to took too long to runtime resume from runtime suspended state. This issue happens becuase the touchpad has a rather small buffer to store up to 13 input events, so if the host doesn't read those events in time (i.e. runtime resume takes too long), events are dropped from the touchpad's buffer. The bottleneck is D3cold delay it waits when transitioning from D3cold to D0, hence remove the delay to make the resume faster. I've tested some systems with intel-lpss and haven't seen any regression.

mfd: intel-lpss-pci: Fix clock speed for 38a8 UART This device is found in the MacBookPro16,2, and as the MacBookPro16,1 is from the same generation of MacBooks and has a UART with bxt_uart_info, it was incorrectly assumed that the MacBookPro16,2's UART would have the same info. This led to the wrong clock speed being used, and the Bluetooth controller exposed by the UART receiving and sending random data, which was incorrectly assumed to be an issue with the Bluetooth stuff, not an error with the UART side of things. Changing the info to spt_uart_info changes the clock speed and makes it send and receive data correctly.

The default SDA hold time for Broxton may fail with arbitration lost errors on Apollo Lake: i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration Fix this by using different default device properties on Apollo Lake than Broxton.

mfd: Add support for Intel Sunrisepoint LPSS devices The new coming Intel platforms such as Skylake will contain Sunrisepoint PCH. The main difference to the previous platforms is that the LPSS devices are compound devices where usually main (SPI, HSUART, or I2C) and DMA IPs are present. This patch brings the driver for such devices found on Sunrisepoint PCH.

mfd: lpss: Fix Intel Kaby Lake PCH-H properties There are a few issues on Intel Kaby Lake PCH-H properties added by commit a6a576b78e09 ("mfd: lpss: Add Intel Kaby Lake PCH-H PCI IDs"): - Input clock of I2C controller on Intel Kaby Lake PCH-H is 120 MHz not 133 MHz. This was probably copy-paste error from Intel Broxton I2C properties. - There is no default I2C SDA hold time specified which is used when ACPI doesn't provide it. I got information from Windows driver team that Kaby Lake PCH-H can use the same configuration than Intel Sunrisepoint PCH. - Common HS-UART properties are not used. Fix these by reusing the Sunrisepoint properties on Kaby Lake PCH-H.

mfd: intel-lpss: Fix Intel Cannon Lake LPSS I2C input clock Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C than Sunrisepoint which uses 120 MHz. Preliminary information was that both share the same clock rate but actual silicon implements elevated rate for better support for 3.4 MHz high-speed I2C. This incorrect input clock rate results too high I2C bus clock in case ACPI doesn't provide tuned I2C timing parameters since I2C host controller driver calculates them from input clock rate. Fix this by using the correct rate. We still share the same 230 ns SDA hold time value than Sunrisepoint.
