Add dtsi file for ASR8751C SoC and dts file for ASR8751C AquilaC development
board. Also add necessary dt-bindings document, header files.
Will add more driver of ASR8751C SoC in later patches.

+* ASR AXI/APB Simple Bus
+
+This file documents core properties in ASR AXI and APB bus.
+
+The ASR8751C SoC has APB and AXI buses for cores to access its
+controllers, suchas i2c, sdh, rtc, clock, power management registers
+etc. Most ASR SoCs share the common architecture for buses.
+Generally APB and AXI bus have a source clock and power control, and
+clock rate can be changed and power can be shutdown in low power mode.
+
+Required properties for AXI bus:
+- compatible: should be "asr,axi-bus", "simple-bus".
+- #address-cells: could be 1, or 2
+- #size-cells: could be 1, or 2
+- reg: iomem address of AXI bus registers
+- ranges: register ranges
+
+Example:
+ axi@d4200000 { /* AXI */
+ compatible = "asr,axi-bus", "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0 0xd4200000 0 0x00200000>;
+ ranges = <0 0 0 0xffffffff>;
+
+ };
+
+Required properties for APB bus:
+- compatible: should be "asr,apb-bus", "simple-bus".
+- #address-cells: could be 1, or 2
+- #size-cells: could be 1, or 2
+- reg: iomem address of APB bus registers

+* UART Controller of ASR8751C SoCs
+
+Required properties:
+- compatible : should be "asr,uart"
+- reg: iomem address and length of uart registers
+- interrupts : Should be the interrupt number
+- clocks: clock required by uart
+- clock-frequency: frequency of clock source
+- dmas: dma channel used by uart tx or rx
+- dma-names: dma name of uart tx or rx
+
+Example:
+
+ uart0: uart@d4017000 {

To: Rob Herring, Mark Rutland, devicetree, linux-kernel; +Cc: Qiao Zhou
From: Qiao Zhou <qiaozhou@asrmicro.com>
Add initial dtsi file to support ASR Aquilac SoC. It has two clusters.
Cluster0 has 4 * Cortex-A53 and Cluster1 has 4 * Cortex-A73.
Also add dts file to support ASR Aquilac SoC development board which is
based on ASR AquilaC SoC.

* [PATCH 7/7] arm64: dts: add dts files for asr Aquilac SoC
@ 2019-03-23 14:01 ` qiaozhou
0 siblings, 0 replies; 22+ messages in thread
From: qiaozhou @ 2019-03-23 14:01 UTC (permalink / raw)
To: Rob Herring, Mark Rutland, devicetree, linux-kernel; +Cc: Qiao Zhou
From: Qiao Zhou <qiaozhou@asrmicro.com>
Add initial dtsi file to support ASR Aquilac SoC. It has two clusters.
Cluster0 has 4 * Cortex-A53 and Cluster1 has 4 * Cortex-A73.
Also add dts file to support ASR Aquilac SoC development board which is
based on ASR AquilaC SoC.

Please convert this to DT schema (yaml) format. Most other SoC families
are converted already.

Patch 5 can be combined with this one. It is part of the binding.

You should probably have a node for each of these blocks if they are
separate blocks. DT nodes should match h/w blocks.

However, how do all the blocks have a single interrupt unless it's a
shared interrupt.

Clock controllers need some input clocks to have any output clocks.
