Link the ARM GIC to the INTC-SYS module clock, and add it to the "always on" PM Domain, so it can be power managed using that clock. Note that currently the GIC-400 driver doesn't support module clocks nor Runtime PM, so this must be handled as a critical clock. Signed-off-by:

Current Audio-DMAC is assigned "rx" as Audio-DMAC0, "tx" as Audio-DMAC1. Thus, DVC "tx" should be assigned as Audio-DMAC1, instead of Audio-DMAC0. Because of this, current platform board (using SRC/DVC/SSI) Playback/Capture both will use same Audio-DMAC0 (but it depends on data path). First note is that this "rx" and "tx" are from each IP point, it doesn't mean Playback/Capture. Second note is that Audio DMAC assigned on DT is only for Audio-DMAC, Audio-DMAC-peri-peri has no entry. => Audio-DMAC -> Audio-DMAC-peri-peri -- HW connection Playback case [Mem] => [SRC]--[DVC] -> [SSI]--[Codec] rx ~~~~~~~~~~~~ Capture [Mem] <= [DVC]--[SRC] <- [SSI]--[Codec] tx ~~~~~~~~~~~~ Signed-off-by:

The Cortex-A15/A7 cache controllers are integrated controllers, and thus the device nodes representing them should not have unit-addresses or reg properties. Fixes: 2c3de367 ("ARM: dts: r8a7790: Fix W=1 dtc warnings") Signed-off-by:

Since everybody copied my own mistake from the DT binding example, let's address all the offenders in one swift go. Most of them got the CPU interface size wrong (4kB, while it should be 8kB), except for both keystone platforms which got the control interface wrong (4kB instead of 8kB). In a few cases where I knew for sure what implementation was used, I've added the "arm,gic-400" compatible string. I'm 99% sure that this is what everyone is using, but short of having the TRM for all the other SoCs, I've left them alone. Acked-by:

Use recently added R-Car Gen 2 fallback binding for msiof nodes in DT for r8a7790 SoC. This has no run-time effect for the current driver as the initialisation sequence is the same for the SoC-specific binding for r8a7790 and the fallback binding for R-Car Gen 2. Signed-off-by:

clk_get() on a disabled clock node will return -EPROBE_DEFER, which can cause drivers to be deferred forever if such clocks are referenced in their devices' clocks properties.

* Fixed rate and fixed factor clocks do not require an clock-output-names property. * Since 07705583 ("clk: shmobile: div6: Make clock-output-names optional") Renesas div6 clocks do not require a clock-output-names property. In the above cases there is only one clock output and its name is taken from that of the clock node. Accordingly, remove the unnecessary clock-output-names properties and as necessary the nodes.

This patch enables to use thermal-zone on r8a7790. This thermal sensor can measure temperature from -40000 to 125000, but over 117000 can be critical on this chip. Thus, default critical temperature is now set as 115000 (this driver is using 5000 steps) (Current critical temperature is using it as 90000, but there is no big reason about it) And it doesn't check thermal zone periodically (same as current behavior). You can exchange it by modifying polling-delay[-passive] property. You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS, but you need to take care to use it, since it will call orderly_poweroff() it it reaches to the value. echo $temp > /sys/class/thermal/thermal_zone0/trip_point_0_temp Signed-off-by:

Add the device node for the external SCIF_CLK. The presence of the SCIF_CLK crystal and its clock frequency depends on the actual board. Add the two optional clock sources (ZS_CLK and SCIF_CLK for the internal resp. external clock) for the Baud Rate Generator for External Clock (BRG) to all SCIF and HSCIF device nodes. This increases the range and accuracy of supported baud rates on (H)SCIF. Signed-off-by:
