* [GIT PULL] Amlogic 64-bit DT changes for v4.16, round 3
From: Kevin Hilman @ 2018-01-06 0:26 UTC (permalink / raw)
To: linux-arm-kernel
Arnd, Olof,
A final round of 64-bit DT changes for Amlogic SoCs.
These were just waiting for the clock dependencies to land in the clock
tree which they now have. I've merged the same tag into this branch to
avoid any dependency issues.
Thanks,
Kevin
The following changes since commit 43b9f617b5f98f2f7abb508fef5e535e5fb66a41:

* [PATCH 1/3] ARM: dts: rockchip: drop veyron's nonstandard 'backlight-boot-off'
From: Brian Norris @ 2018-01-06 0:47 UTC (permalink / raw)
To: linux-arm-kernel
This was used out-of-tree as a hack for resolving issues where some
systems expect the backlight to turn on automatically at boot, while
others expect to manage the backlight status via a DRM/panel driver.
Those issues have since been fixed upstream in pwm_bl.c without device
tree hacks, and so this un-documented property should no longer be
useful.

Thanks for the warning. I'll wait and merge these after -rc1 to be sure
of all dependencies.

I've realized that I can accomplish this if I use some #if 0/#endif blocks
temporarily if that sounds OK.

CONFIG_HID_MULTITOUCH is not a new option, but just got moved around.

All these changes came from savedefconfig.

Agreed. The savedefconfig change should really be a separate patch.

Sorry for giving you a hard time on this. I will rework it by adding
CONFIG_CPU_FREQ_STAT option only in that patch.

I did it based on linux-next, it should be on linux-next-pm branch, I redo
the patch set V2 based on linux-next-pm, also redo the test,
sorry for the inconvenience.

* [PATCH 0/7] Initial Allwinner H6 support
From: Icenowy Zheng @ 2018-01-06 4:18 UTC (permalink / raw)
To: linux-arm-kernel
This patchset adds initial support for the Allwinner H6 SoC.
It's quite different from earlier Allwinner SoCs. For example, the
memory map is refactored, and the CCU is rearranged. It's also the first
Allwinner SoC with PCI Express interface, and the second one with USB
3.0 (the first one is A80).
This patchset adds the most basical support for it, including the main pin
controller, the main CCU and the basical device tree.
Icenowy Zheng (7):
pinctrl: sunxi: add support for pin controllers without bus gate
pinctrl: sunxi: support pin controllers with holes among IRQ banks
pinctrl: sunxi: add support for the Allwinner H6 main pin controller
clk: sunxi-ng: Support fixed post-dividers on NKMP style clocks
clk: sunxi-ng: add support for the Allwinner H6 CCU
arm64: allwinner: h6: add the basical Allwinner H6 DTSI file
arm64: allwinner: h6: add support for Pine H64 board

* [PATCH 1/7] pinctrl: sunxi: add support for pin controllers without bus gate
From: Icenowy Zheng @ 2018-01-06 4:23 UTC (permalink / raw)
To: linux-arm-kernel
The Allwinner H6 pin controllers (both the main one and the CPUs one)
have no bus gate clocks.
Add support for this kind of pin controllers.

* [PATCH 2/7] pinctrl: sunxi: support pin controllers with holes among IRQ banks
From: Icenowy Zheng @ 2018-01-06 4:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20180106042326.46519-1-icenowy@aosc.io>
The Allwinner H6 SoC have its pin controllers with the first IRQ-capable
GPIO bank at IRQ bank 1 and the second bank at IRQ bank 5. This
situation cannot be processed with the current pinctrl IRQ code, as it
only expects a offset to all IRQ banks.
Update the code to use a logical IRQ bank to hardware IRQ bank map, so
the new situation in H6 main pin controller can be processed. The old
special situation which uses a constant offset (on A33 and V3s, both
with a offset of 1) can be also processed with the new code.

* [PATCH 3/7] pinctrl: sunxi: add support for the Allwinner H6 main pin controller
From: Icenowy Zheng @ 2018-01-06 4:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20180106042326.46519-1-icenowy@aosc.io>
The Allwinner H6 SoC has two pin controllers, one main controller
(called CPUX-PORT in user manual) and one controller in CPUs power
domain (called CPUS-PORT in user manual).
This commit introduces support for the main pin controller on H6.
The pin bank A and B are not wired out and hidden from the SoC's
documents, however it's shown that the "ATE" (an AC200 chip
co-packaged with the H6 die) is connected to the main SoC die via these
pin banks. The information about these banks is just copied from the BSP
pinctrl driver, but re-formatted to fit the mainline pinctrl driver
format.

* [PATCH 4/7] clk: sunxi-ng: Support fixed post-dividers on NKMP style clocks
From: Icenowy Zheng @ 2018-01-06 4:38 UTC (permalink / raw)
To: linux-arm-kernel
On the new Allwinner H6 SoC, multiple PLL's are NMP style clocks
(modelled as NKMP with no K) and have fixed post-dividers.
Add fixed post divider support to the NKMP style clocks.

* [PATCH 6/7] arm64: allwinner: h6: add the basical Allwinner H6 DTSI file
From: Icenowy Zheng @ 2018-01-06 5:09 UTC (permalink / raw)
To: linux-arm-kernel
Allwinner H6 is a new SoC with Cortex-A53 cores from Allwinner, with its
memory map fully reworked and some high-speed peripherals (PCIe, USB
3.0) introduced.
This commit adds the basical DTSI file of it, including the clock
support and UART support.

* [PATCH] mdio-sun4i: Fix a memory leak
From: Christophe JAILLET @ 2018-01-06 8:00 UTC (permalink / raw)
To: linux-arm-kernel
If the probing of the regulator is deferred, the memory allocated by
'mdiobus_alloc_size()' will be leaking.
It should be freed before the next call to 'sun4i_mdio_probe()' which will
reallocate it.
Fixes: 4bdcb1dd9feb ("net: Add MDIO bus driver for the Allwinner EMAC")

* [PATCH] arm64: dts: rockchip: add roc-rk3328-cc board
From: djw at t-chip.com.cn @ 2018-01-06 9:45 UTC (permalink / raw)
To: linux-arm-kernel
From: Levin Du <djw@t-chip.com.cn>
The roc-rk3328-cc is a credit card size single board computer using the
Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supporting
up to 2GB 2133MHz LPDDR4 memory. It provides eMMC module socket, MicroSD
Card slot, USB 2.0/3.0, Gigabit Ethernet, HDMI/CVBS, Infrared Receiver,
SPDIF/I2S, and SPI/I2C/UART/PWM interfaces.
The devicetree currently supports basic peripherals.

Thanks for the testing, I can only reproduce this on my ARM64 platform
which the CPU will cache the PMD in TLB, from my knowledge, only Cortex-A75
will do this, so ARM64 platforms which are not A75 based can't be reproduced
either.
Catalin, Will, I can reproduce this issue in about 3 minutes with following
simplified test case [1], and can trigger panic as [2], could you take a look
as well?

Thanks for the confirm.

Yes, As I said in my patch, this is just RFC, comments are welcomed :)

+* Hisilicon Universal Flash Storage (UFS) Host Controller
+
+UFS nodes are defined to describe on-chip UFS hardware macro.
+Each UFS Host Controller should have its own node.
+
+Required properties:
+- compatible : compatible list, contains one of the following -
+ "hisilicon,hi3660-ufs", "jedec,ufs-1.1" for hisi ufs
+ host controller present on Hi36xx chipset.
+- reg : should contain UFS register address space & UFS SYS CTRL register address,
+- interrupt-parent : interrupt device
+- interrupts : interrupt number
+- clocks : List of phandle and clock specifier pairs
+- clock-names : List of clock input name strings sorted in the same
+ order as the clocks property. "ref_clk", "phy_clk" is optional
+- freq-table-hz : Array of <min max> operating frequencies stored in the same
+ order as the clocks property. If this property is not
+ defined or a value in the array is "0" then it is assumed
+ that the frequency is set by the parent clock or a
+ fixed rate clock source.
+- resets : reset node register, one reset the clk and the other reset the controller
+- reset-names : describe reset node register
+
+Example:
+
+ ufs: ufs at ff3b0000 {
+ compatible = "hisilicon,hi3660-ufs", "jedec,ufs-1.1";
+ /* 0: HCI standard */
+ /* 1: UFS SYS CTRL */

+ <0x0 0xff3b1000 0x0 0x1000>;
+ interrupt-parent = <&gic>;
+ interrupts = <GIC_SPI 278 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&crg_ctrl HI3660_CLK_GATE_UFSIO_REF>,
