[PATCH 00/11] Broadcom Stingray SOC Initial Support

[PATCH 00/11] Broadcom Stingray SOC Initial Support

[Anup Patel]

This patchset adds initial support of Broadcom Stingray SOC
by reusing existing Broadcom iProc device drivers.

Most of the patches in this patchset are DT patches except
the Stingray clock tree support which just one patch.

This patchset is based on Linux-4.11 and it is also available
at stingray-v1 branch of https://github.com/Broadcom/arm64-linux.git

Anup Patel (3):
  dt-bindings: bcm: Add Broadcom Stingray bindings document
  arm64: dts: Initial DTS files for Broadcom Stingray SOC
  arm64: dts: Add PL022, PL330 and SP805 DT nodes for Stingray

Oza Pawandeep (1):
  arm64: dts: Add I2C DT nodes for Stingray SoC

Pramod Kumar (3):
  arm64: dts: Add NAND DT nodes for Stingray SOC
  arm64: dts: Add pinctrl DT nodes for Stingray SOC
  arm64: dts: Add GPIO DT nodes for Stingray SOC

Sandeep Tripathy (3):
  dt-bindings: clk: Extend binding doc for Stingray SOC
  clk: bcm: Add clocks for Stingray SOC
  arm64: dts: Add clock DT nodes for Stingray SOC

Srinath Mannam (1):
  arm64: dts: Add PWM and SDHCI DT nodes for Stingray SOC

[PATCH 03/11] clk: bcm: Add clocks for Stingray SOC

[Anup Patel]

From: Sandeep Tripathy <sandeep.tripathy-dY08KVG/lbpWk0Htik3J/w@public.gmane.org>

This patch adds support for Stingray clocks in iproc
ccf. The Stingray SOC has various plls based on iproc
pll architecture.

Can you make this a platform driver instead? Are all these clks
really used for getting the interrupt and timers running?

It describes various plls and soc specific details for the particular
SOC based on
bcm iproc architecture. the core functionality is implemented for all
Broadcom SOC
using iproc pll architecture in generic iproc drivers  eg: clk-iproc-pll.c

Not all clocks needed early except the genpll3. sp804 timer clks are derived
from genpll. we will send revised patch to have most of the clocks registered
via platform driver probe.

[PATCH 04/11] arm64: dts: Initial DTS files for Broadcom Stingray SOC

[Anup Patel]

The Broadcom Stingray SoC is a new member in Broadcom iProc
SoC family.

This patch adds initial DTS files for Broadcom Stingray SoC
and two of its reference boards (bcm958742k and bcm958742t).

We have lot of reference boards and large number of devices
in Broadcom Stingray SoC so eventually we will have quite
a few DTS files for Stingray. To tackle, we have added a
separate directory for Stingray DTS files.

Sorry for missing that during the internal review, the ranges property
here should include the 6300_0000 offset such that everything else under
the "scr" node is relative to that base address. This makes it a lot
easier to understand the different physical addresses involved and the
bus topology.

Sure, I will do this.

This memreserve comment was changed from the internal version of the 
dtsi file.  Comment is now misleading as I don't think this memreserve 
is used at all.  EFI Loader passes in the memory configuration.  Comment 
needs to be updated to indicate this is not used by standard bootloader. 
  Or, simply remove the memreserve here.

[PATCH 10/11] arm64: dts: Add PL022, PL330 and SP805 DT nodes for Stingray

[Anup Patel]

We have two instance of PL022 SPI controllers, one instance of
DMA PL330, and one non-secure SP805 Watchdog on Stingray SOC.

This patch adds DT nodes for the above mentioned devices in
Stingray DT.

[PATCH 08/11] arm64: dts: Add GPIO DT nodes for Stingray SOC

[Anup Patel]

From: Pramod Kumar <pramod.kumar@broadcom.com>

The GPIOs on Stingray SOC are based on iProc GPIOs hence
using this we add GPIO DT nodes for Stingray SOC.
