This patch set includes various updates for mach-lpc32xx, including DT binding
for serial and dts updates. A new reference board is supported (EA3250). The
board support file phy3250.c is updated to become more general, useable for
other boards also. There is still board specific stuff in it, though (some
devicetree auxdata).
Further, clock updates, DMA support, MMC support and a defconfig update for
LPC32xx is included.

Since we now support two MTD NAND controllers (MLC and SLC) for LPC32xx via DT,
we don't initialize the SLC controller statically anymore, but do it via the
clock setup (see previous patch).

This patch takes into account that the MTD NAND MLC controller needs more
registers, located actually before the previously allocated memory range,
already starting at 200a8000 instead of 200b0000.
Further, the interrupt for the controller is configured.

There is another reference/development board for the LPC32xx SoC (besides the
Phytec 3250): The Embedded Artists LPC3250 board. This patch adds a default dts
file for it.

Cc: Roland Stigge
This patch adds support for the MMC controller of the LPC32xx SoC to the
platform initialization via the pl08x primecell driver. Lacking more complete
DT support, done via DT auxdata.

* [PATCH 12/14] ARM: LPC32xx: DT conversion of Standard UARTs

This patch switches from static serial driver initialization to devicetree
configuration. This way, the Standard UARTs of the LPC32xx SoC can be enabled
individually via DT.
E.g., instead of Kconfig configuration, the phy3250.dts activates
UARTs 3 and 5.

* [PATCH 12/14] ARM: LPC32xx: DT conversion of Standard UARTs
@ 2012-06-11 11:02 ` Roland Stigge
0 siblings, 0 replies; 66+ messages in thread
From: Roland Stigge @ 2012-06-11 11:02 UTC (permalink / raw)
To: linux-arm-kernel
This patch switches from static serial driver initialization to devicetree
configuration. This way, the Standard UARTs of the LPC32xx SoC can be enabled
individually via DT.
E.g., instead of Kconfig configuration, the phy3250.dts activates
UARTs 3 and 5.

LPC32xx SoC, adjusting the compatible strings, adding interrupts and status

ARCH_NR_GPIOS was defined statically to include exactly all SoC specific GPIOs.
Now if additional GPIOs need to be added dynamically, e.g. via DT, none are
available. Removing the mach specific setting, leaving ARCH_NR_GPIOS to the
default of 256 (currently in include/asm-generic/gpio.h).

These change in my unstable/dma-pl08x branch, patches have been posted
already, but I don't deem them to be totally stable yet. Waiting on
OMAP people to get their mainline kernel restored to a buildable state
so I can continue my DMA engine work.

These change in my unstable/dma-pl08x branch, patches have been posted
already, but I don't deem them to be totally stable yet. Waiting on
OMAP people to get their mainline kernel restored to a buildable state
so I can continue my DMA engine work.

The proper way to write this is 'status = "disabled";', with a 'd' at
the end.

Should this not be in the same patch as the one that moves the device over
to DT probing? Otherwise you have a non-working setup if only one patch
is applied.

Thanks for the note!
Funnily, I always did it this way. Looks like initially, I copied from
somewhere else (wrongly). Indeed, we have lots of "disable", see also:
omap3-beagle.dts
omap4-panda.dts
omap4-sdp.dts

The actual driver is new for v3.6 (hopefully), DT-only.
Rather than merging the patches, I'd let the key driver go in via input,
and the clock.c adjustment via arm-soc.

Ah, right. Note that the kernel checks only for "ok" and "okay" strings,
anything else is interpreted as "disabled". We should use the correct
string anyway of course.

We have a few options here:
1) Take the patch as I posted it (needs adjustments as soon as the API
changed and becomes stable)
2) Remove the DMA related patches from the LPC32xx series for now (which
would be unfortunate)
3) Let me build upon some tree that already looks worthwhile to play
with already (which one?)
What would you suggest?
Thanks in advance,
Roland
