This patch adds support EXYNOS5250 SoC which has two A15 cores
can be used on mobile and tablet devices.
Changes since v2:
- update interrupt number declaration for single zImage
of exynos4 and exynos5
- allow to select for exynos4 and exynos5 together
- add support EINT for exynos4 and exynos5
- add l2 cache initializer for exynos5250
Changes since v1:
- address comments from mailing list
- update the option accordingly common.[ch]
- update clock part
- get rid of static mapping for uart
- add device tree enabled board file(mach-exynos5-dt.c)
- add initial dts file for EXYNOS5250(SoC), SMDK5250(Board)

According to commit cc511b8d84d8 ("ARM: 7257/1: EXYNOS: introduce
arch/arm/mach-exynos/common.[ch]"), we don't need to declare extern
for exynos4_map_io(), exynos4_init_clocks(), exynos4_init_uarts(),
and exynos_init(). And the exynos4210_register_clocks() and
exynos4212_register_clocks depend on each SoC not ARCH_EXYNOS4.
So this patch fixed above.

This patch adds clock-exynos5.c for EXYNOS5250 now
and that can be used for other EXYNOS5 SoCs later.

* [PATCH v3 03/12] ARM: EXYNOS: add clock part for EXYNOS5250 SoC
@ 2012-03-13 15:30 ` Kukjin Kim
0 siblings, 0 replies; 56+ messages in thread
From: Kukjin Kim @ 2012-03-13 15:30 UTC (permalink / raw)
To: linux-arm-kernel
This patch adds clock-exynos5.c for EXYNOS5250 now
and that can be used for other EXYNOS5 SoCs later.

* [PATCH v3 04/12] ARM: EXYNOS: add initial setup-i2c0 for EXYNOS5

In all of Samsung platform, the setup-i2c0.c file for I2C channel 0
is always compiled. So when supporting new SoC,it should be updated
for it. Since EXYNOS5 GPIO will be supported after this, there is no
setup gpio in there now. It will be implemented with that, of course.

Actually, the base address of uart is different between EXYNOS4
and EXYNOS5 and this patch enables to support uart for EXYNOS4
and EXYNOS5 SoCs at runtime.

* [PATCH v3 05/12] ARM: EXYNOS: add support uart for EXYNOS4 and EXYNOS5

From: Kukjin Kim @ 2012-03-13 15:30 UTC (permalink / raw)
To: linux-arm-kernel
Actually, the base address of uart is different between EXYNOS4
and EXYNOS5 and this patch enables to support uart for EXYNOS4
and EXYNOS5 SoCs at runtime.

To: linux-arm-kernel, linux-samsung-soc; +Cc: arnd, olof, Kukjin Kim
This patch add support for EXYNOS5250 SoC has two Cortex-A15 cores.
Since actually, most codes in mach-exynos/ are used commonly for
EXYNOS4 and EXYNOS5 the EXYNOS5/EXYNOS5250 has been implemented
in mach-exynos/.

* [PATCH v3 06/12] ARM: EXYNOS: add support for EXYNOS5250 SoC
@ 2012-03-13 15:30 ` Kukjin Kim
0 siblings, 0 replies; 56+ messages in thread
From: Kukjin Kim @ 2012-03-13 15:30 UTC (permalink / raw)
To: linux-arm-kernel
This patch add support for EXYNOS5250 SoC has two Cortex-A15 cores.
Since actually, most codes in mach-exynos/ are used commonly for
EXYNOS4 and EXYNOS5 the EXYNOS5/EXYNOS5250 has been implemented
in mach-exynos/.

To: linux-arm-kernel, linux-samsung-soc; +Cc: arnd, olof, Kukjin Kim
ARM: EXYNOS: irqs.h for exynos4 and exynos5 - WIP
This patch adds the interrupt definitions for EXYNOS5250 at
<mach/irqs.h> file. Basically, now it is needed for EXYNOS5250
interrupt and will be updated for single zImage next time.
Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

* [PATCH v3 07/12] ARM: EXYNOS: add interrupt definitions for EXYNOS5250
@ 2012-03-13 15:30 ` Kukjin Kim

From: Kukjin Kim @ 2012-03-13 15:30 UTC (permalink / raw)
To: linux-arm-kernel
ARM: EXYNOS: irqs.h for exynos4 and exynos5 - WIP
This patch adds the interrupt definitions for EXYNOS5250 at
<mach/irqs.h> file. Basically, now it is needed for EXYNOS5250
interrupt and will be updated for single zImage next time.
Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

* [PATCH v3 08/12] ARM: EXYNOS: support EINT for EXYNOS4 and EXYNOS5
2012-03-13 15:30 ` Kukjin Kim

From: Kukjin Kim @ 2012-03-13 15:30 UTC (permalink / raw)
To: linux-arm-kernel, linux-samsung-soc; +Cc: arnd, olof, Eunki Kim, Kukjin Kim
From: Eunki Kim <eunki_kim@samsung.com>
The GPIOs of EXYNOS4 and EXYNOS5 are changed to use
ioremap instead of static mapping. It alse causes the
change of external interrupt IO mapping. This patch
changes EXYNOS4 to EXYNOS for common use and changes
EINT_x macros for supporting dynamic IO mapping.

* [PATCH v3 08/12] ARM: EXYNOS: support EINT for EXYNOS4 and EXYNOS5
@ 2012-03-13 15:30 ` Kukjin Kim
0 siblings, 0 replies; 56+ messages in thread
From: Kukjin Kim @ 2012-03-13 15:30 UTC (permalink / raw)
To: linux-arm-kernel
From: Eunki Kim <eunki_kim@samsung.com>
The GPIOs of EXYNOS4 and EXYNOS5 are changed to use
ioremap instead of static mapping. It alse causes the
change of external interrupt IO mapping. This patch
changes EXYNOS4 to EXYNOS for common use and changes
EINT_x macros for supporting dynamic IO mapping.

This patch adds initial dts file for EXYNOS5250 SoC. This dts
file is including the SoC specific devices and properties. And
adds the dts file for SMDK5250 board which uses the EXYNOS5250
dts file. Its board specific properites will be added later.

* [PATCH v3 12/12] ARM: dts: add initial dts file for EXYNOS5250, SMDK5250

To: linux-arm-kernel
This patch adds initial dts file for EXYNOS5250 SoC. This dts
file is including the SoC specific devices and properties. And
adds the dts file for SMDK5250 board which uses the EXYNOS5250
dts file. Its board specific properites will be added later.

Can you explain why this patch is still needed? The exynos5250_dt_map_io
function does not call s3c24xx_init_uarts() at all, so it seems that most
of this patch just adds dead code that would only be needed for the non-dt
case.

Can you explain this patch more? It only seems to make the
code less generic, but there is no indication if calling
the scu_get_core_count() function is actually wrong on
exynos5.

Looks basically ok to me. I've commented on patches 5 and 9 and
in both cases, I would either like to see the patch get dropped
or the changeset description expanded to give a good explanation
why the change is actually needed.

irq_to_gpio is going away, so it's not a good idea to add it under that name.
Add a local function locally at the top of this file instead. and call
it something else.

I think this would be cleaner as two small helpers and one check for SoC

Hi,
A couple of comments below.

irq_to_gpio is going away, so it's not a good idea to add it under that name.
Add a local function locally at the top of this file instead. and call
it something else.

I think this would be cleaner as two small helpers and one check for SoC
version instead.

Having these specific bootargs in the include file rarely makes sense, it's
better to have firmware update from the settings in firmware and just have a very
simple fallback here.
In particular initrd is quite custom to hardcode like that.

lowercase hex here and elsewhere in these files, please.
Also, technically no need to specify a unit address (@<foo>) in the device node
name unless you need it to tell more than one entry apart, but it's become
customary to always add them on ARM for some reason.

Agree, looks quite reasonable. I had a few nits as well but nothing

The external interrupt numbers for Exynos4 and Exynos5 have been
swapped. This needs to be fixed.

Yes, the bootargs is no mandatory in dts file and u-boot bootargs can be
set. OK, we can simplify it here like following.
bootargs = "root=/dev/ram0 rw ramdisk=8192 console=ttySAC1,115200"

Contrary to Cortex-A9, Cortex-A15 has no regarding scu register so
EXYNO5250 can not get the number of core from that like EXYNOS4 SoCs.

Yes, as you said, dt can support uart without most of this changes so we
can drop adding/setup platform devices for uart here. But I thought
non-dt exynos4 supporting is still available in mach-exynos/ and
actually it is used for many product now and exynos5 can be selected for
single zImage without CONFIG_OF. Even though we will move to only
supporting dt world in mach-exynos/ for all of EXYNOS SoCs in the near
future. So would be removed it when non-dt exynos4 does not support.
Thanks.
Best regards,
Kgene.
