Cover letter [PATCH v7 0/5] ARM64: Add support for FSL's LS2085A SoC

Hi Bhupesh,

The series looks mostly fine to me, though I have a couple of comments below.

Quoted 9 lines · Bhupesh Sharma

This patchset adds the support for FSL's LS2085A SoC which is based on ARMv8 architecture.

This patchset also has patches which address DT compatible strings for nodes which appear un-documented.

The enable-method for the CPU nodes is left for the bootloader (u-boot or UEFI) to patch-up which is expected to be PSCI v0.2

Quoted 10 lines

This patchset has been tested with the following patches which add PSCI v0.2 support in ARMv8 u-boot:
http://patchwork.ozlabs.org/patch/383556/
http://patchwork.ozlabs.org/patch/383555/
http://patchwork.ozlabs.org/patch/383557/
http://patchwork.ozlabs.org/patch/383558/
http://patchwork.ozlabs.org/patch/383559/
http://patchwork.ozlabs.org/patch/383560/
http://patchwork.ozlabs.org/patch/383561/
http://patchwork.ozlabs.org/patch/383562/

Has there been any progress on these? last I saw there was some pending rework, and I was holding off a thorough review of the PSCI parts until that had happened.

Rebased against cleanup/dts-subdirs branch of the arm-soc tree

Changes from v6:
----------------
* Rebased against cleanup/dts-subdirs branch of the arm-soc tree.
* As a result, [PATCH 4/6] and [PATCH 5/6] of the v6 series are squashed into one patch ([PATCH 4/5] of this series).

Note:
-----
Optional GIC-500 regs like GICC, GICH and GICV are currently not tested and hence are not part of the DTS patch.

Quoted 4 lines

Please review and consider for merge.

Bhupesh Sharma (5):
Documentation: DT: Add bindings for FSL NS16550A UART

Regardless of anything else, this patch should be queued given it adds missing documentation for a binding already supported by the kernel.

Quoted 2 lines

Documentation: DT: Add entry for FSL LS2085A SoC and Simulator model
Documentation: DT: Add entry for FSL Management Complex

Are there any patches adding support for the management complex? There's nothing in mainline that uses "fsl,qoriq-mc", and nothing in this series adds support.

Thanks,
Mark.
