platform/x86: silead depends on I2C being built-in

2017-02-13T22:39:48+00:00

The new driver cannot be a loadable module, so if I2C is loadable, we get this link error: drivers/platform/built-in.o: In function `silead_ts_dmi_init': silead_dmi.c:(.init.text+0x2ef): undefined reference to `i2c_bus_type' This makes the Kconfig dependency stricter to require I2C=y.

platform/x86: add support for devices with Silead touchscreens

2017-02-13T22:39:48+00:00

On ACPI based tablets, the ACPI touchscreen node only contains info on the gpio and the irq, and is missing any info on the axis. This info is expected to be built into the tablet model specific version of the driver shipped with the os-image for the device. Add support for getting the missing info from a table built into the driver, using dmi data to identify which entry of the table to use and add info for the CUBE iwork8 Air and Jumper EZpad mini3 tablets on which this code was tested / developed.

platform/x86: Support Turbo Boost Max 3.0 for non HWP systems

2017-02-04T01:47:20+00:00

On platforms supporting Intel Turbo Boost Max Technology 3.0, the maximum turbo frequencies (turbo ratio) of some cores in a CPU package may be higher than the other cores in the same package. In that case, better performance can be achieved by making the scheduler prefer to run tasks on the CPUs with higher max turbo frequencies. On Intel® Broadwell Xeon systems, it is optional to turn on HWP (Hardware P-States). When HWP is not turned on, the BIOS doesn't present required CPPC (Collaborative Processor Performance Control) tables. This table is used to get the per CPU core maximum performance ratio and inform scheduler (in cpufreq/intel_pstate driver). On such systems the maximum performance ratio can be read via over clocking (OC) mailbox interface for each CPU. This interface is not architectural and can change for every model of processors. This driver reads maximum performance ratio of each CPU and set up the scheduler priority metrics. In this way scheduler can prefer CPU with higher performance to schedule tasks.

platform/x86: dell-smbios: Auto-select as needed

2017-02-03T12:04:54+00:00

Dell-smbios is a helper module, it serves no purpose on its own, so do not present it as an option to the user. Instead, select it automatically whenever a driver which needs it is selected. Also select DCDBAS as needed, instead of depending on it, so that the Dell driver options are always visible. As a clean-up, I removed the "default n" statements as they are not needed (n is the default default.)

platform/x86: Enable Atom PMC platform clocks

2017-01-27T00:21:59+00:00

The BayTrail and CherryTrail platforms provide platform clocks through their Power Management Controller (PMC). The SoC supports up to 6 clocks (PMC_PLT_CLK[0..5]) with a frequency of either 19.2 MHz (PLL) or 25 MHz (XTAL) for BayTrail and a frequency of 19.2 MHz (XTAL) for CherryTrail. These clocks are available for general system use, where appropriate. For example, the usage for platform clocks suggested in the datasheet is the following: PLT_CLK[0..2] - Camera PLT_CLK[3] - Audio Codec PLT_CLK[4] - PLT_CLK[5] - COMMs Signed-off-by: Irina Tirdea Signed-off-by: Pierre-Louis Bossart Acked-by: Andy Shevchenko Signed-off-by: Stephen Boyd
