* [PATCH v2 08/11] clk: qcom: clk-cpu-8996: Prepare PLLs on probe
From: Ilia Lin @ 2018-01-04 11:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1515064215-22202-1-git-send-email-ilialin@codeaurora.org>
The PLLs must be prepared enabled during the probe to be
accessible by the OPPs. Otherwise an OPP may switch
to non-enabled clock.

* [PATCH v2 07/11] clk: qcom: cpu-8996: Add support to switch below 600Mhz
From: Ilia Lin @ 2018-01-04 11:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1515064215-22202-1-git-send-email-ilialin@codeaurora.org>
From: Rajendra Nayak <rnayak@codeaurora.org>
The CPU clock controllers primary PLL operates on a single VCO range,
between 600Mhz and 3Ghz. However the CPUs do support OPPs with
frequencies between 300Mhz and 600Mhz. In order to support running the
CPUs at those frequencies we end up having to lock the PLL at twice the
rate and drive the CPU clk via the PLL/2 output and SMUX.
So for frequencies above 600Mhz we follow the following path
Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk
and for frequencies between 300Mhz and 600Mhz we follow
Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk

Each of the CPU clusters on msm8996 and powered via a primary
PLL and a secondary PLL. The primary PLL is what drivers the
CPU clk, except for times when we are reprogramming the PLL
itself, when we temporarily switch to an alternate PLL.
Use clock rate change notifiers to support this.

* [PATCH v2 04/11] clk: qcom: Add CPU clock driver for msm8996
From: Ilia Lin @ 2018-01-04 11:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1515064215-22202-1-git-send-email-ilialin@codeaurora.org>
From: Rajendra Nayak <rnayak@codeaurora.org>
Each of the CPU clusters (Power and Perf) on msm8996 are
clocked via 2 PLLs, a primary and alternate. There are also
2 Mux'es, a primary and secondary all connected together
as shown below
+-------+
XO | |
+------------------>0 |
| |
PLL/2 | SMUX +----+
+------->1 | |
| | | |
| +-------+ | +-------+
| +---->0 |
| | |
+---------------+ | +----------->1 | CPU clk
|Primary PLL +----+ PLL_EARLY | | +------>
| +------+-----------+ +------>2 PMUX |
+---------------+ | | | |
| +------+ | +-->3 |
+--^+ ACD +-----+ | +-------+
+---------------+ +------+ |
|Alt PLL | |
| +---------------------------+
+---------------+ PLL_EARLY
The primary PLL is what drives the CPU clk, except for times
when we are reprogramming the PLL itself (for rate changes) when
we temporarily switch to an alternate PLL. A subsequent patch adds
support to switch between primary and alternate PLL during rate
changes.
The primary PLL operates on a single VCO range, between 600Mhz
and 3Ghz. However the CPUs do support OPPs with frequencies
between 300Mhz and 600Mhz. In order to support running the CPUs
at those frequencies we end up having to lock the PLL at twice
the rate and drive the CPU clk via the PLL/2 output and SMUX.
So for frequencies above 600Mhz we follow the following path
Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk
and for frequencies between 300Mhz and 600Mhz we follow
Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk
Support for this is added in a subsequent patch as well.
ACD stands for Adaptive Clock Distribution and is used to
detect voltage droops. We do not add support for ACD as yet.
This can be added at a later point as needed.

* [PATCH v2 02/11] clk: qcom: Fix .set_rate to handle alpha PLLs w/wo dynamic update

From: Taniya Das <tdas@codeaurora.org>
Alpha PLLs which do not support dynamic update feature
need to be explicitly disabled before a rate change.
The ones which do support dynamic update do so within a
single vco range, so add a min/max freq check for such
PLLs so they fall in the vco range.

* [PATCH v2 01/11] soc: qcom: Separate kryo l2 accessors from PMU driver
From: Ilia Lin @ 2018-01-04 11:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1515064215-22202-1-git-send-email-ilialin@codeaurora.org>
The driver provides kernel level API for other drivers
to access the MSM8996 L2 cache registers.
Separating the L2 access code from the PMU driver and
making it public to allow other drivers use it.
The accesses must be separated with a single spinlock,
maintained in this driver.

I switch to Shawn's for-next branch, but when doing 'make savedefconfig', I
still see some other changes, anyway, I will resend a patch based on Shawn's for-next
branch, thanks!

* [PATCH] arm64: Allocate elfcorehdr & crashkernel mem before any reservation
From: Poonam Aggrwal @ 2018-01-04 10:38 UTC (permalink / raw)
To: linux-arm-kernel
From: Poonam Aggrwal <poonam.aggrwal@nxp.com>
Address for both crashkernel memory and elfcorehdr can be assigned
statically. For crashkernel memory it is via crashkernel=SIZE at ADDRESS
and elfcorehdr_addr via by kexec-utils in dump kernel device tree.
So memory should be reserved for both the above areas before any
other memory reservations are done. Otherwise overlaps may happen and
memory allocations will fail leading to failure in booting the
dump capture kernel.

Would you mind using SPDX tags instead of this fine but long legalese?
This is documented in Thomas patches [1].
Also if you could spread the word in your team, this would earn you
good karma points.
Thank you!

* [PATCH 07/12] arm64: dts: mt7622: turn uart0 clock to real ones
From: sean.wang at mediatek.com @ 2018-01-04 9:40 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.1515057696.git.sean.wang@mediatek.com>
From: Sean Wang <sean.wang@mediatek.com>
This patch also cleans up two oscillators that provide clocks for MT7623.
Switch the uart clocks to the real ones while at it.

* [PATCH 05/12] arm64: dts: mt7622: add PMIC MT6380 related nodes
From: sean.wang at mediatek.com @ 2018-01-04 9:40 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.1515057696.git.sean.wang@mediatek.com>
From: Sean Wang <sean.wang@mediatek.com>
Enable pwrap and MT6380 on mt7622-rfb1 board. Also add all mt6380
regulator nodes in an alone file to allow similar boards using MT6380
able to resue the configuration.

* [PATCH 02/12] arm64: dts: mt7622: add clock controller device nodes
From: sean.wang at mediatek.com @ 2018-01-04 9:40 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.1515057696.git.sean.wang@mediatek.com>
From: Sean Wang <sean.wang@mediatek.com>
Add clock controller nodes for MT7622 and include header for topckgen,
infracfg, pericfg, apmixedsys, ethsys, sgmiisys, pciesys and ssusbsys
for those devices nodes to be added afterwards.
In addition, provides an oscillator node for the source of PLLs and dummy
clock for PWARP to complement missing support of clock gate for the
wrapper circuit in the driver.
