2017-06-09ARM: dts: meson8: add and use the real clock controllerMartin Blumenstingl
This removes the dummy clk81 gate and replaces it with the actual clock controller's CLKID_CLK81. This will also allow us to pass the real clock IDs to all devices where the clock is controlled by clkc in the future.

2017-06-10ARM: dts: uniphier: Add generic compatible string for I2C EEPROMJavier Martinez Canillas
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

2017-06-08KVM: arm/arm64: Allow setting the timer IRQ numbers from userspaceChristoffer Dall
First we define an ABI using the vcpu devices that lets userspace set the interrupt numbers for the various timers on both the 32-bit and 64-bit KVM/ARM implementations. Second, we add the definitions for the groups and attributes introduced by the above ABI. (We add the PMU define on the 32-bit side as well for symmetry and it may get used some day.) Third, we set up the arch-specific vcpu device operation handlers to call into the timer code for anything related to the KVM_ARM_VCPU_TIMER_CTRL group. Fourth, we implement support for getting and setting the timer interrupt numbers using the above defined ABI in the arch timer code. Fifth, we introduce error checking upon enabling the arch timer (which is called when first running a VCPU) to check that all VCPUs are configured to use the same PPI for the timer (as mandated by the architecture) and that the virtual and physical timers are not configured to use the same IRQ number.

2017-06-08KVM: arm/arm64: Move timer IRQ default init to arch_timer.cChristoffer Dall
We currently initialize the arch timer IRQ numbers from the reset code, presumably because we once intended to model multiple CPU or SoC types from within the kernel and have hard-coded reset values in the reset code. As we are moving towards userspace being in charge of more fine-grained CPU emulation and stitching together the pieces needed to emulate a particular type of CPU, we should no longer have a tight coupling between resetting a VCPU and setting IRQ numbers. Therefore, move the logic to define and use the default IRQ numbers to the timer code and set the IRQ number immediately when creating the VCPU.

2017-06-08ARM: dts: armadillo800eva: Split LCD mux and gpioGeert Uytterhoeven
Configuration of the lcd0 pinmux group and GPIO hog for the external GPIO mux are done using a single device node, causing the "output-high" property to be applied to both. This will fail for the pinmux group, but doesn't cause any harm, as the failure is ignored silently. However, after "pinctrl: sh-pfc: propagate errors on group config", the failure will become fatal, leading to a broken display: sh-pfc e6050000.pin-controller: pin_config_group_set op failed for group 102 sh-pfc e6050000.pin-controller: Error applying setting, reverse things back sh-pfc e6050000.pin-controller: failed to select default state Move the GPIO hog to its own node to fix this.
