This series introduce the support of the Armada 3700 family: it is the
first ARM64 SoC of the mvebu family submitted to the mainline!
Currently there are two members of the Armada 3700 family, the only
difference is the number of core: the Armada 3710 comes with one
Cortex-A53 whereas the Armada 3720 comes with 2 Cortex-A53. In this
series we enabled only the minimum to boot, pinctrl and clock tree
will come soon.
The changes in this third version are very small (see the changelog).
The first two patches patches are here to be able to use the the
ARCH_MVEBU for the Armada 3700 SoCs. The first ones is only here to
have standalone series but it comes from Thomas Petazzoni's series:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/472625
The third patch introduces a new serial driver for the uart used on
this SoC. The driver remains simple even if the hardware is capable of
doing more.
The forth one adapts the ahci driver to support the Armada 3700 SoC.
The forth patch updates the binding documentation with the new
compatible string.
The fifth patch adds a new entry Kconfig entry for this SoC family.
I took the opportunity of this series to tidy up the Marvell related
files in the binding documentation with the seventh patch.
The eighth patch introduces the compatible string for the SoCs of the
Armada 3700 family.
The ninth patch could be considered as the bulk of this series: it
adds the device tree files for the Armada 3700 SoCs and for the
reference board.
With the introduction of this new family the MAINTAINERS file, the
Marvell README and the ARM64 defconfig files have to be updated: it is
the purpose of the last 3 patches.
The patches 3 and 4 could be taken directly by the maintainer of their
respective subsystem as there is no dependency at all with the rest of
the series. I think that the rest of the series should go through the
arm-soc maintainer but in doubt I also added the ARM64 maintainer as
suggested by get_maintainer.pl.
Thanks,
Gregory
Changelog:
v1 -> v2
- Added Rob acked-by on patches 3, 6 and 7
- Used armada3700_uart instead of mvebu_uart for the uart driver:
suggested by Mark
- In mvebu-uart, do not use anymore TTY_MAJOR, or ttyS, but dynamic
major and ttyMV: pointed by Alan
- Use tty_termios_copy_hw in mvebu_uart_set_termios: suggested by Alan
- Use ARCH_MVEBU instead of creating ARCH_ARMADA_3700: suggested by
Jisheng
- Added a new irqchip pacthes to fix build on ARM64 when ARCH_MVEBU is
selected
- Removed marvell,armada3700 from the device tree binding and directly
used marvell,armada3710 for common feature: pointed by Rob
- Fix memory node with coorect size in armada-3720-db.dts: suggested
by Mark
v2 -> v3
- Renamed the remaining ttyS into ttyMV: reported by Greg KH
- Fixed the order of the compatible in the example of the binding
documentation: pointed by Rob
- Fix a typo in Kconfig entry: pointed by Thomas Petazzoni

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Instead of building the irq-armada-370-xp driver directly when
CONFIG_ARCH_MVEBU is enabled, this commit introduces an intermediate
CONFIG_ARMADA_370_XP_IRQ hidden Kconfig option.
This allows this option to select other interrupt-related Kconfig
options (which will be needed in follow-up commits) rather than having
such selects done from arch/arm/mach-<foo>/.

The irq-armada-370-xp driver can only be built for ARM 32 bits. The mvebu
family had grown with a new ARM64 SoC which will also select the
ARCH_MEVBU configuration. Since "ARM: mvebu: use the ARMADA_370_XP_IRQ
option", the ARM32 mvebu SoC directly select this new option. Selecting
it by default when ARCH_MEVBU is selected is no more needed.
This patch removes this dependency, thanks to this, a kernel for ARM64
mvebu SoC can be built without error due this driver.

The irq-armada-370-xp driver can only be built for ARM 32 bits. The mvebu
family had grown with a new ARM64 SoC which will also select the
ARCH_MEVBU configuration. Since "ARM: mvebu: use the ARMADA_370_XP_IRQ
option", the ARM32 mvebu SoC directly select this new option. Selecting
it by default when ARCH_MEVBU is selected is no more needed.
This patch removes this dependency, thanks to this, a kernel for ARM64
mvebu SoC can be built without error due this driver.

* [PATCH v3 03/12] serial: mvebu-uart: initial support for Armada-3700 serial port

From: Wilson Ding <dingwei@marvell.com>
Armada-3700's uart is a simple serial port, which doesn't
support. Configuring the modem control lines. The uart port has a 32
bytes Tx FIFO and a 64 bytes Rx FIFO
The uart driver implements the uart core operations. It also support the
system (early) console based on Armada-3700's serial port.
Known Issue:
The uart driver currently doesn't support clock programming, which means
the baud-rate stays with the default value configured by the bootloader
at boot time

* [PATCH v3 03/12] serial: mvebu-uart: initial support for Armada-3700 serial port
@ 2016-02-08 17:14 ` Gregory CLEMENT

To: linux-arm-kernel
From: Wilson Ding <dingwei@marvell.com>
Armada-3700's uart is a simple serial port, which doesn't
support. Configuring the modem control lines. The uart port has a 32
bytes Tx FIFO and a 64 bytes Rx FIFO
The uart driver implements the uart core operations. It also support the
system (early) console based on Armada-3700's serial port.
Known Issue:
The uart driver currently doesn't support clock programming, which means
the baud-rate stays with the default value configured by the bootloader
at boot time

The main difference in the new Armada 3700 is that no address
decoding needs to take place in the driver probe.

directly in the arm directory. It's time to have our proper directory
inside it, and move all the files in it.

Over the last releases we have added more and more Marvell related binding
directly in the arm directory. It's time to have our proper directory
inside it, and move all the files in it.

Add initial dtsi files to support Marvell Armada 3700 SoC with Cortex-A53
CPUs. There are two members in this family: the Armada 3710 (Single CPU)
and the Armada 3720 (Dual CPUs).
It also adds a dts file for the Marvell Armada 3720 DB board.

From: Gregory CLEMENT @ 2016-02-08 17:14 UTC (permalink / raw)
To: linux-arm-kernel
Add initial dtsi files to support Marvell Armada 3700 SoC with Cortex-A53
CPUs. There are two members in this family: the Armada 3710 (Single CPU)
and the Armada 3720 (Dual CPUs).
It also adds a dts file for the Marvell Armada 3720 DB board.

Now that we support Armada 37xx, let's add this family of SoC to the
Marvell documentation, and a reference to a link with more details about
those processors. As for Armda 39x, no datasheet is publicly
available at this time.

Looks good. I wonder if we should also enable this for COMPILE_TEST, e.g.
config ARMADA_370_XP_IRQ
bool "Marvell Armada 3xx/XP/3xxx interrupt controller" if COMPILE_TEST && !ARCH_MVEBU
default ARCH_MVEBU
select GENERIC_IRQ_CHIP
If we do this, it's probably something outside of your series that we should
do for all patches, so don't worry about it here. Any opinions on the general
question?
