* [PATCH v2 0/2] support USB2 PHY OTG port for rk3399
From: William Wu @ 2016-11-03 2:06 UTC (permalink / raw)
To: linux-arm-kernel
This series add support for rk3399 USB2 PHY0 and PHY1 OTG port.
rk3399 has two USB2 PHYs, and each USB2 PHY is comprised of one
Host port and one OTG port. We have supported Host port before,
and try to support OTG port now.
Test on rk3399-evb board.

I thought I acked this one...
Skimming through it again, I think you would want to add CLK_SET_PARENT_RATE
to the hdmi and mipi dsi module clocks.

I guess it's a question of what's clearer. I like kimage_vaddr +
TEXT_OFFSET because it clearly states we are checking from the
start of the kernel image vs. _text only shows the start of the
text region. Yes, it's technically the same but a little less
obvious. I suppose that could be solved with some more elaboration
in the comment.

Laura

If the concept of __pa_symbol is okay then yes I think all uses of __pa
should eventually be converted for consistency and debugging.

I'm unable to reproduce this. I've tried enabling LSE with defconfig and
mainline, using compilers that both do and don't support the instructions.
What am I missing?

I still need to figure out the __pa() stuff in the last two patches.

Can't we use _text instead of kimage_vaddr + TEXT_OFFSET? That way we don't
need CFLAGS_physaddr.o.
Or KERNEL_START / KERNEL_END from <asm/memory.h>?
Otherwise, this looks good to me (though I haven't grokked the need for
__pa_symbol() yet).
Thanks,

Nit: s/marco/macro/
I see there are some other uses of __pa() that look like they could/should be
__pa_symbol(), e.g. in mark_rodata_ro().
I guess strictly speaking those need to be updated to? Or is there a reason
that we should not?

Mark.

I completely agree with you and I was pushing for a generic "arm,legacy-scpi"
compatible until this binding was acked by Rob.
Anyways, I will add the generic compatible and post the changes.

which should translate to:

in the generic binding, right?

Agreed, also the way Markus' patch is designed makes it such that we
first try the full and current option name, and if not supported, try
the second (and earlier, now obsolete) option name, so I really don't
see a lot of room for things to go wrong here...

Basically our LPC device use a CPU address range (not a bus range as
a bus range is supposed to be remapped into a cpu range using the range
property).
This CPIU address range is [0, PCIBIOS_MIN_IO-1].
This patch effectively does 2 things:
1) reserve the cpu physical range [0, PCIBIOS_MIN_IO-1] so that it cannot
be used by PCI I/O space (see drivers/pci/pci.c)
2) Avoid to translate the cpu addresses that belongs to LPC (in fact
for this device we do not specify a range property in the DT): see
changes in __of_translate_address()
3) Do not retrieve an I/O token for I/O addresses that belong to LPC
(in fact LPC accessors work directly on the CPU physical addresses):
see change in __of_address_to_resource()
Probably 1) and 3) can be put in a separate patch with respect to 2)...
What do you think?

See of_isa_indirect_io() called just before of_bus_isa_match(parent)...

Effectively we check if the device is lying on a ISA bus, if the accessors
struct pointer is set, if the parent device is an ISA bus and if the device
physical addresses are within the range reserved for LPC...
So we check all the conditions that allow us to say that this device
is lying on a special ISA bus device

* [PATCH v6 4/4] arm64: dts: add Pine64 support
From: Maxime Ripard @ 2016-11-02 21:50 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.6088b64645bde9b847d2fede5ecb15a0e204a9dd.1478123413.git-series.maxime.ripard@free-electrons.com>
From: Andre Przywara <andre.przywara@arm.com>
The Pine64 is a cost-efficient development board based on the
Allwinner A64 SoC.
There are three models: the basic version with Fast Ethernet and
512 MB of DRAM (Pine64) and two Pine64+ versions, which both
feature Gigabit Ethernet and additional connectors for touchscreens
and a camera. Or as my son put it: "Those are smaller and these are
missing." ;-)
The two Pine64+ models just differ in the amount of DRAM
(1GB vs. 2GB). Since U-Boot will figure out the right size for us and
patches the DT accordingly we just need to provide one DT for the
Pine64+.

* [PATCH v6 2/4] arm64: dts: add Allwinner A64 SoC .dtsi
From: Maxime Ripard @ 2016-11-02 21:50 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.6088b64645bde9b847d2fede5ecb15a0e204a9dd.1478123413.git-series.maxime.ripard@free-electrons.com>
From: Andre Przywara <andre.przywara@arm.com>
The Allwinner A64 SoC is a low-cost chip with 4 ARM Cortex-A53 cores
and the typical tablet / TV box peripherals.
The SoC is based on the (32-bit) Allwinner H3 chip, sharing most of
the peripherals and the memory map.
Although the cores are proper 64-bit ones, the whole SoC is actually
limited to 4GB (including all the supported DRAM), so we use 32-bit
address and size cells. This has the nice feature of us being able to
reuse the DT for 32-bit kernels as well.
This .dtsi lists the hardware that we support so far.

* [PATCH v6 0/4] arm64: Allwinner A64 support based on sunxi-ng
From: Maxime Ripard @ 2016-11-02 21:50 UTC (permalink / raw)
To: linux-arm-kernel
Hi,
As it was in the first iteration, this is the A64 support based on the
new sunxi-ng clock framework.
The support for it is quite minimal at the moment, but it should be
fairly easy to add new devices, as most of the design is shared with
older SoCs.
Let me know what you think,
Maxime
Changes from v5:
- Removed the redundant ioremap error code
- Converted to the generic pin muxing functions
- Removed the stale DT vendor removal
Changes from v4:
- Removed merged patches and added Chen-Yu's Acked by
- Fixed the interrupt-cells property to 3
- Fixed the rtc order
- Added the CLK_SET_RATE_UNGATE flags to the PLLs
- Added the CLK_SET_RATE_PARENT flags to the cpu clock
- Fixed a few offset and width
Changes from v3:
- Fix patch split
Changes from v2:
- Added pull-ups on the Pine64 i2c bus
- Removed the PMU since it doesn't work
- Refactored the sunxi-ng framework to deal with the specifities of
the A64 CCU, especially in terms of minimum factors.
- Fixed a few things in the CCU driver: added CLK_SET_RATE PARENT
flags, fixed some mux width, etc.
- Converted the CCU driver to a platform driver
- Added the DRAM reset line
- Added IDs for the USB muxes (even though we're not using them yet)
Changes from v1:
- Split the A64 CCU support out of the H3 driver
- Added the PMU support
- Removed the clocks node
- Rebased on top of current sunxi/clk-for-4.9 branch

Ok, thanks Viresh.
Would you or Rafael take patch 1/4 "cpufreq: pxa: use generic platdev driver for
device-tree" through your tree please ?
I'll take patches 2 and 3 through my tree, and we'll wait for clock patches to
hit clock tree before I ask patch 4/4 to be applied.
Cheers.

It is probably worth mentioning that the existing driver name is "ohci"
which is a bit too generic.
