76cc1887 (thermal: rcar: add Device Tree support) supported rcar_thermal DT probing. rcar thermal driver doesn't support IRQ on r8a7779 chip since it is using old design IRQ. R-Car/R-Mobile next generation chips are using new design IRQ, and rcar thermal driver is supporting these. This patch adds rcar_thermal DT support for r8a7779 without IRQ.

R-Car H1 datasheet GIC number is indicating GIC ICCIAR / interrupt ID number, not SPI number, but current marzen board code is using gic_spi() with un-understandable calculation. This patch adds new gic_iid() macro which means ICCIAR / interrupt ID, and used the number currently written on datasheet.

Each CPU Hotplug implementation for mach-shmobile is now self-contained, so this change removes unused helper code in hotplug.c. The two CPU Hotplug capable SoCs sh73a0 and r8a7779 remain unchanged.

Update the SMP code for R8A7779 to make use of the shared SCU function scu_power_mode() together with the early setup code in shmobile_secondary_vector_scu. With this patch in place the secondary CPUs modify the SCU setting during early boot instead of letting other CPUs deal with the coherency setting before boot. In other words, we used to setup coherency before boot in r8a7779_boot_secondary() but that bit is now instead handled by the code in shmobile_secondary_vector_scu.

Update the r8a7779 CPU Hotplug code to use SCU PSR to wait for the target CPU core. Previously the shared code in hotplug.c was used to let cpu_kill() wait for cpu_die().

Rename headsmp-sh73a0.S into headsmp-scu.S and introduce shmobile_secondary_vector_scu(). The goal is to be able to share the function above between all mach-shmobile SoCs that use SCU for SMP. So far only sh73a0 use this. At this time the SCU base address is still hard coded in headsmp-scu.S to 0xf0000000, but this will be changed in the future.

Allow a minimal setup of the r8a7779 SoC using a flattened device tree. In particular, configure the i2c and ethernet controllers using a flattened device tree. SCI serial controller and TMU clock source, whose drivers do not yet support configuration using a flattened device tree, are still configured using C code in order to allow booting of a board with this SoC. The ethernet controller also requires a regulator which is a board property. A sample snippet DT for the marzen board is as follows: /dts-v1/; /include/ "r8a7779.dtsi" / { fixedregulator3v3: fixedregulator@0 { compatible = "regulator-fixed"; regulator-name = "fixed-3.3V"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-boot-on; regulator-always-on; }; }; &lan0 { vddvario-supply = <&fixedregulator3v3>; vdd33a-supply = <&fixedregulator3v3>; }; Signed-off-by: NSimon Horman <horms+renesas@verge.net.au>
