Use newly added R-Car GPIO Gen2 fallback compat string in place of now deprecated non-generation specific R-Car GPIO fallback compat string in the DT of the r8a7743 SoC. This should have no run-time effect as the driver matches against the per-SoC compat string before considering the fallback compat string. Signed-off-by:

Use newly added R-Car GPIO Gen1 fallback compat string in place of now deprecated non-generation specific R-Car GPIO fallback compat string in DT of r8a7779 SoC. As the driver does not match on "renesas,gpio-r8a7779" there are some run-time considerations for this patch: * When a resulting DTB is used with kernels newer than v4.14 this should not have any run-time effect as renesas,rcar-gen1-gpio is matched by the driver since commit dbd1dad2 ("gpio: rcar: add gen[123] fallback compatibility strings") * However, when used with older kernels GPIO will be disabled as no compat string match will be made by the driver. The regression documented above for the new DTB with old kernel case is acceptable in my opinion. Signed-off-by:

Enable ostm0 and ostm1 timers to be used as clock source and clockevent source. The timers provides greater accuracy than the already enabled mtu2 one. With these enabled: clocksource: ostm: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 57352151442 ns sched_clock: 32 bits at 33MHz, resolution 30ns, wraps every 64440619504ns ostm: used for clocksource ostm: used for clock events Signed-off-by:

The following 'capacity-dmips-mhz' dt property values are used: Cortex-A15: 1024, Cortex-A7: 539 They have been derived form the cpu_efficiency values: Cortex-A15: 3891, Cortex-A7: 2048 by scaling them so that the Cortex-A15s (big cores) use 1024. The cpu_efficiency values were originally derived from the "Big.LITTLE Processing with ARM Cortex
™ -A15 & Cortex-A7" white paper (http://www.cl.cam.ac.uk/~rdm34/big.LITTLE.pdf). Table 1 lists 1.9x (3891/2048) as the Cortex-A15 vs Cortex-A7 performance ratio for the Dhrystone benchmark. The following platform is affected once cpu-invariant accounting support is re-connected to the task scheduler: r8a7790-lager Signed-off-by:Dietmar Eggemann <dietmar.eggemann@arm.com> Signed-off-by:

This patch adds a .dtsi that describes the camera daughter board and a .dts to describe the HW made of iWave's RZ/G1M SoM, iWave's RZ/G1M/G1N Qseven carrier board, and the camera daughter board. The camera daughter board .dtsi adds support for ttySC[14]. Signed-off-by:

Since the same carrier board may host RZ/G1M and RZ/G1N based Systems on Module, the DT architecture for iwg20d-q7 needs better decoupling. This patch provides: * iwg20d-q7-common.dtsi - its purpose is to define the carrier board definitions, and its content is basically the same as the previous version of r8a7743-iwg20d-q7.dts, only it has no reference to the SoM .dtsi, and that's why the filename doesn't mention the SoC name any more. * r8a7743-iwg20d-q7.dts - its new purpose is to put together the SoM .dtsi (r8a7743-iwg20m.dtsi) and the carrier board .dtsi defined by this very patch, along with "model" and "compatible" properties. The final DT architecture to describe the board is now: r8a7743-iwg20d-q7.dts # Carrier Board + SoM ├── r8a7743-iwg20m.dtsi # SoM │ └── r8a7743.dtsi # SoC └── iwg20d-q7-common.dtsi # Carrier Board and maximizes the reuse of the definitions for the carrier board and for the SoM.

Add properties to describe the reset topology for on-SoC devices: - Add the "#reset-cells" property to the CPG/MSSR device node, - Add resets and reset-names properties to the various device nodes. This allows to reset SoC devices using the Reset Controller API. Note that resets usually match the corresponding module clocks. Exceptions are: - The audio module has resets for the Serial Sound Interfaces only, - The display module has only a single reset for all DU channels, but adding reset properties for the display is postponed.
