[PATCH v3 0/2] arm64: Add support for Juno development board

[PATCH v3 0/2] arm64: Add support for Juno development board

[Liviu Dudau]

Hi,

This patchset adds device tree support for ARM's AArch64 Juno development
board. It enables use of various peripherals on the board, from USB and
networking to I2C and PL011 UART.

The patches can also be found in the repository at:

   git://github.com/ARM-software/linux.git juno/dts-for-armsoc

for you to fetch.


Changes vs v2:
  - rebased on top of arm-soc/next/cleanup
  - Split the flat device tree into several files. Although some
    commonality still remains in the main .dts file with other
    devices trees (see psci node) it is not clear what benefits can
    be gained from moving such a small node into its own file.
  - Ordered nodes according to their address space
  - Removed ulpi_phy node as it was redundant and the bindings non-standard.

v2 version: http://lkml.org/lkml/2014/11/10/242

Best regards,
Liviu

[PATCH v3 1/2] arm64: Create link to include/dt-bindings to enable C preprocessor use.

[Liviu Dudau]

DT files used in the compilation phase can be preprocessed by the C
preprocessor. This requires an include/dt-bindings directory to be
present in the arch/arm64/boot/dts directory.

[PATCH v3 2/2] arm64: Add Juno board device tree.

[Liviu Dudau]

This adds support for ARM's Juno development board (rev 0).
It enables most of the board peripherals: UART, I2C, USB, MMC and
100Mb ethernet. There is no support at the moment for clock setting
and HDLCD driver which depends on it.

[PATCH v3 2/2] arm64: Add Juno board device tree.

[Liviu Dudau]

This adds support for ARM's Juno development board (rev 0).
It enables most of the board peripherals: UART, I2C, USB, MMC and
100Mb ethernet. There is no support at the moment for clock setting
and HDLCD driver which depends on it.

Sorry, I should have spotted this earlier: all these interrupts are
*level*, not edge. This happens to work because the GIC's config
register is RO for PPIs on Juno, but still...

Yes, I've seen your other email to Suravee regarding interrupt triggering and I was trying to
find the relevant bits in Juno to tell me why I've put the info in DT this way. Maybe I *did*
copy-paste this part from FVP DT though.

I will send a patch to Olof to update.

Yes, I've seen your other email to Suravee regarding interrupt triggering and I was trying to
find the relevant bits in Juno to tell me why I've put the info in DT this way. Maybe I *did*
copy-paste this part from FVP DT though.

I will send a patch to Olof to update.

Yeah, looks like most (if not all) DTs in the tree are broken. Any
chance you could write a sweeping patch to fix them all (at least for
the ARM implementations)?

The APM and Cavium implementations also carry the same values, and I
suppose this is a bug too, but someone with access to documentation
should figure this out.

Thanks,

Same change already has been posted as part of adding Exynos7 SoC 
support, as Exynos7 patches have been accepted in Kukjin's tree, I think 
following patch [1] as part of Exynos7 series [2] can also be taken.

Hi Pankaj,

I don't know how Olof and Arnd are going to handle this, but I believe
Arnd has already merged my patchset into the arm-soc tree.
