v4 cover Support for Fujitsu MB86S7X SoCs

Hello,

Fujitsu have a series of SoC already shipping based around
variations of 2xCA7+2xCA15 big.LITTLE architecture, and we would like to upstream the basic support in this series.

MB86S70 is a big.LITTLE platform with 2xCA7+2xCA15 and an additional
CM3 as the master. MB86S73 is a simple 2xCA7 and an additional CM3 master.

The DT includes references to sdhci patches which are being sent to
the mmc list at the same time.

We welcome any comments or questions.

Changes since v3:
* Identify platform, by checking presence of DT node "fujitsu,mb86s70-scb-1.0" before populating cpu clocks and MCPM support.
* Disable clock upon gpio module remove
* Lower init level of gpio driver from subsys_initcall to module_init
* Use managed device resource allocation in MHU driver

Changes since v2:
* Minor cleanup of MCPM as suggested by Nicolas Pitre.

Changes since v1:
* Thanks to Arnd, modified clock driver to populate clocks only when some user need them. Node name changed from "fujitsu,mb86s70-clk" to "fujitsu,mb86s70-crg11" . Controller+Domain+Port of a clock are now three cells specified by the user node.
* aliases moved into board DTS files
* Voltage supply moved as per-board DT node.
* Removed default overly verbose loglevel=8
* Specify -march=armv7-a flag for mcpm.c and smc.S that contain ARMv7 specific code.
* Removed wrongly put outer_flush_all(), now using standard v7_exit_coherency_flush() instead of platform specific macro.
* Simplified GPIO offset calculations in gpio-mb86s70.c driver. And added .remove() for the driver
* ARM MHU driver provided a .remove() to enable module unloading.
* A few other misc cleanups suggested in v1 submission.

Thanks.

PATCH v4 1/8 ARM: Add platform support for Fujitsu MB86S7X SoCs

From: Jassi Brar <[email protected]>

The MB86S7X is a bigLITTLE configuration of 2xCA7 & 2xCA15 under Linux. And the remote master firmware (called SCB) running on CM3. Linux asks for things to be done over Mailbox API, to SCB which controls most of the important things. variations S70 & S73 are supported.

+Fujitsu SCB (Mailbox's Remote Firmware) bindings
+------------------------------------------------
+
+The firmware (running of a remote Cortex-M3 master) on Fujitsu's MB86S7X
+platforms is named SCB. The SCB owns most of core h/w IPs like Clock,
+CPUFreq/DVFS, CPUIdle/SMP, Thermal, a recovery block device and even an
+I2C controller. Linux has to map all of these functionalities on to
+the Mailbox API and get things done by the remote master.
+ Let the current state of SCB firmware be versioned 1.0.
+
+Required properties :
+- compatible : Shall contain "fujitsu,mb86s70-scb-1.0"
+- reg : Point to SharedMemory used for Mailbox protocol.
+- mboxes : phandle to the mailbox controller:channel node.
+
+The consumer specifies the desired clock pointing to its phandle.
+
+Example:
+
+	mhu: mhu0 at 2b1f0000 {
+		#mbox-cells = <1>;
+		compatible = "arm,mbox-mhu";
+		reg = <0 0x2b1f0000 0x1000>;
+		interrupts = <0 36 4>, /* LP Non-Sec */
+			     <0 35 4>, /* HP Non-Sec */
+			     <0 37 4>; /* Secure */
+		clocks = <&clk 0 2 1>;
+		clock-names = "clk";
+	};
+
+	mhu_client: scb at 2e000000 {
+		compatible = "fujitsu,mb86s70-scb-1.0";
+		reg = <0 0x2e000000 0x4000>; /* SHM for IPC */
+		mboxes = <&mhu 1>;
+	};

+ARM MHU Mailbox Driver
+======================
+
+The ARM's Message-Handling-Unit (MHU) is a mailbox controller that has
+3 independent channels/links to communicate with remote processor(s).
+ MHU links are hardwired on a platform. A link raises interrupt for any
+received data. However, there is no specified way of knowing if the sent
+data has been read by the remote. This driver assumes the sender polls
+STAT register and the remote clears it after having read the data.
+
+Mailbox Device Node:
+====================
+
+Required properties:
+--------------------
+- compatible:		Shall be "arm,mbox-mhu"
+- reg:			Contains the mailbox register address range (base
+			address and length)
+- #mbox-cells		Shall be 1
+- interrupts:		Contains the interrupt information corresponding to
+			each of the 3 links of MHU.
+
+Example:
+--------
+
+	mhu: mailbox at 2b1f0000 {
+		#mbox-cells = <1>;
+		compatible = "arm,mbox-mhu";
+		reg = <0 0x2b1f0000 0x1000>;
+		interrupts = <0 36 4>,
+			     <0 35 4>,

PATCH v4 3/8 ARM: MB86S7X: Add MCPM support

In reply to Vincent Yang

The remote firmware(SCB) owns the SMP control. This MCPM driver gets CPU/CLUSTER power up/down done by SCB over mailbox.

PATCH v4 4/8 clk: Add clock driver for mb86s7x

In reply to Vincent Yang

From: Jassi Brar <[email protected]>

The CRG11 clock controller is managed by remote f/w.
This driver simply maps Linux CLK ops onto mailbox api.

Fujitsu's ARCH_MB86S7X is multi_v7 compatible, so add options to multi_v7_defconfig. Also add a new defconfig for MB86S7X for those who want the kernel built specifically for ARCH_MB86S7X.

v4 cover Support for Fujitsu MB86S7X SoCs

In reply to Vincent Yang

Hi Arnd, Hi Olof,

... just a polite ping on the patchset.

Thanks.

Quoted 116 lines · Vincent Yang

Hello,

Fujitsu have a series of SoC already shipping based around
variations of 2xCA7+2xCA15 big.LITTLE architecture, and we would like to upstream the basic support in this series.

MB86S70 is a big.LITTLE platform with 2xCA7+2xCA15 and an additional
CM3 as the master. MB86S73 is a simple 2xCA7 and an additional CM3 master.

The DT includes references to sdhci patches which are being sent to
the mmc list at the same time.

We welcome any comments or questions.

Changes since v3:
* Identify platform, by checking presence of DT node "fujitsu,mb86s70-scb-1.0" before populating cpu clocks and MCPM support.
* Disable clock upon gpio module remove
* Lower init level of gpio driver from subsys_initcall to module_init
* Use managed device resource allocation in MHU driver

Changes since v2:
* Minor cleanup of MCPM as suggested by Nicolas Pitre.

Changes since v1:
* Thanks to Arnd, modified clock driver to populate clocks only when some user need them. Node name changed from "fujitsu,mb86s70-clk" to "fujitsu,mb86s70-crg11" . Controller+Domain+Port of a clock are now three cells specified by the user node.
* aliases moved into board DTS files
* Voltage supply moved as per-board DT node.
* Removed default overly verbose loglevel=8
* Specify -march=armv7-a flag for mcpm.c and smc.S that contain ARMv7 specific code.
* Removed wrongly put outer_flush_all(), now using standard v7_exit_coherency_flush() instead of platform specific macro.
* Simplified GPIO offset calculations in gpio-mb86s70.c driver. And added .remove() for the driver
* ARM MHU driver provided a .remove() to enable module unloading.
* A few other misc cleanups suggested in v1 submission.

Thanks.

Hi Arnd, Hi Olof,

... just a polite ping on the patchset.

Hi Jassi,

Olof has been handling all the merges so far, but he probably missed this one as it was neither a pull request nor sent to arm at kernel.org.

I've put the arm at kernel.org alias on Cc now, which I assume will make the thread appear in the right folder for him.
