v3 cover ARM64: Enable SP805 WDT support for FSL LS2080A

This is the v3 of patchset which adds the support for SP805 WDT on FSL LS2080A and also adds the missing documentation of SP805 WDT device-tree bindings.

Rebased against arm-soc/next/dt

Changes since v2:
(v2 can be viewed here: http://permalink.gmane.org/gmane.linux.ports.arm.kernel/463141)
- Addressed Rob's comments regarding the second mandatory CLK source's (WDOGCLK) name in the bindings.

Changes since v1:
(v1 can be viewed here: http://www.spinics.net/lists/devicetree/msg102487.html)

- Addressed Rob and Mark's comments regarding the mandatory CLK sources
- Removed interrupt property from the bindings for now (as discussed
with Mark on IRC) till Will's patch proceeds further and enables handling the WDOG interrupts for each core connected to the same PPI line (http://lists.infradead.org/pipermail/linux-arm-kernel/2015-December/391616.html)

+* ARM SP805 Watchdog Timer (WDT) Controller
+
+SP805 WDT is a ARM Primecell Peripheral and has a standard-id register that
+can be used to identify the peripheral type, vendor, and revision.
+This value can be used for driver matching.
+
+As SP805 WDT is a primecell IP, it follows the base bindings specified in
+'arm/primecell.txt'
+
+Required properties:
+- compatible : Should be "arm,sp805-wdt", "arm,primecell"
+- reg : Base address and size of the watchdog timer registers.
+- clocks : From common clock binding.
+           First clock is PCLK and the second is WDOGCLK.
+           WDOGCLK can be equal to or be a sub-multiple of the PCLK frequency.
+- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
+
+Optional properties:
+- interrupts : Should specify WDT interrupt number.
+
+Examples:
+
+		cluster1_core0_watchdog: wdt at c000000 {
+			compatible = "arm,sp805-wdt", "arm,primecell";
+			reg = <0x0 0xc000000 0x0 0x1000>;
+			clocks = <&clockgen 4 3>, <&clockgen 4 3>;
+			clock-names = "apb_pclk", "wdog_clk";

Thanks Arnd. For now, may-be I can send this patchset with Rob's Acked-by added for 1/2 to 'arm at kernel.org'. So that this can be picked by via the arm-soc tree. Shawn, I hope it's ok with you.

Yeah. I'm maintaining a git tree, collecting all Freescale arm32 platform patches, and sending them to arm-soc for each merge window. If I can be copied on those arm64 patches, I do not mind handling them together with arm32 ones.

Since Rob has acked the SP805 WDT binding documentation patch (patch 1/2 of this series),
can this DTSI change, please be considered for absorption in the arm-
soc tree.
Sure, please submit it for inclusion. Who is the maintainer for arch/arm64/boot/dts/freescale/ ? Can they pick up all the freescale related dts changes and submit them as a pull request? Should they go through Shawn's tree maybe?

Thanks Arnd. For now, may-be I can send this patchset with Rob's Acked-by added for 1/2 to 'arm at kernel.org'. So that this can be picked by via the arm-soc tree. Shawn, I hope it's ok with you.
Yeah. I'm maintaining a git tree, collecting all Freescale arm32 platform patches, and sending them to arm-soc for each merge window. If I can be copied on those arm64 patches, I do not mind handling them together with arm32 ones.

Shawn, Thanks a lot for offering to help.

Sorry for a very delayed response as I was on vacation. I have recently been made responsible by the company to push and track the upstreaming of all armv8 related software within the Digital Networking group of FSL/NXP which is currently the only business unit to use ARMv8 cores. We also agreed in an internal discussion that it will be good for me to also help organize patches for upstream acceptance. I think I can help to make it more effective in communicating community requirements and feedback to all related developers and their management. And I can also help to enable the internal test team to better test the staging patches before they hit the mainline.

Regards,
Leo

v3 cover ARM64: Enable SP805 WDT support for FSL LS2080A

In reply to Bhupesh Sharma

Hi Rob, Mark,

Quoted 2 lines · Bhupesh Sharma

This is the v3 of patchset which adds the support for SP805 WDT on FSL LS2080A and also adds the missing documentation of SP805 WDT device-tree bindings.

Any comments on this version, or does it seems fine for integration into the arm-soc tree.

Regards,
Bhupesh
