[PATCH 0/5] at91: Introduction of at91sam9g10 SOC

[Nicolas Ferre]

AT91sam9g10 is an ARM 926ej-s SOC. It is an evolution of the at91sam9261 with a
faster clock speed: 266/133MHz.

This patchset is relying on the integration of at91sam9g45 already posted. Here
is the patch series that you will have to take into account before applying
those patches.

[PATCH 2/5] at91: Support for at91sam9g10: clocks management

[Nicolas Ferre]

From: Hong Xu <hong.xu@atmel.com>

Add the at91sam9g10 support to the AT91 generic clock file. It takes
advantage of the management by functionalities of those PLLs and clocks.

[PATCH 3/5] at91: Support for at91sam9g10: core chip & board support

[Nicolas Ferre]

From: Hong Xu <hong.xu@atmel.com>

Here are the modification to at91sam9261 files dedicated to the support of
at91sam9g10. This direction has been adopted to minimize code duplication.

All at91sam9261 drivers are enabled in _devices and board- files. Modificaton
to peripherals that support at91sam9g10 will be added in future patches.

[PATCH 4/5] at91/USB: USB drivers modifications for at91sam9g10

[Nicolas Ferre]

From: Hong Xu <hong.xu@atmel.com>

Modify both host and gadget USB drivers for at91sam9g10.
This add a clock management equivalent to at91sam9261 on usb drivers.
It also add the way of handling gadget pull-ups (like the at91sam9261).

[PATCH 4/5] at91/USB: USB drivers modifications for at91sam9g10

[Nicolas Ferre]

Hi,

Here is a little "ping" about integration of this patch.

I wonder if we can consider its inclusion as at91sam9g10 is now
integrated in mainline.
Do you want me to split this in several pieces for host/gadget split.

Thanks.

Maybe we can schedule such an update on top of this patch series.
Indeed, as it impacts also AVR32, I propose to build a patch with both
architecture update once at91sam9g45 and at91sam9g10 patchsets are queued.

A proposition follows.

[RFC PATCH] atmel_lcdfb Kconfig: remove long dependency line

[Nicolas Ferre]

Many Atmel SOC are embedding a LCD controller. This patch removes the long
dependency line for this Atmel LCD framebuffer driver configuration entry.
The ARCH_ATMEL_HAS_FB configuration option is located in the video Kconfig file
as it may be setup by ARM/AT91 and AVR32 chips.

Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

Beware, this proposition goes on top of at91sam9g45 & at91sam9g10 patchsets
already posted. My proposition is to wait for those series are queued before
applying this modification.

Experience shows that this configuration is selected.

The dependency allows to have a good hierarchy in the configuration tree...
Better proposition welcome.

1st - no need for 'default n' - you're specifying something that's already
the default.

2nd - don't make this symbol depend on anything, and don't use the symbol
for anything except providing a dependency for FB_ATMEL.  Instead, let
FB_ATMEL deal with the dependency on FB and ARCH_ATMEL_HAS_FB.

3rd - ISTR we have a convention for these - 'HAVE_foo' for a configuration
option named 'foo'.  So it should probably be HAVE_FB_ATMEL.

The problem is that if I do not setup the dependency here the menu entry
will not be available at the proper level. In fact I will see the Atmel
LCD entry here:
"Graphics support"
 <*> Support for frame buffer devices  --->
 <*> AT91/AT32 LCD Controller support

instead of here:
"Graphics support"
 ---> "Support for frame buffer devices"
      [..]
      <*> "AT91/AT32 LCD Controller support"
      [..]

So I keep the depend.

Ok, changed to HAVE_FB_ATMEL indeed.

The depend is on ARCH_ATMEL_HAS_FB which has no description (and therefore
does not appear in the menus) not the symbol for "AT91/AT32 LCD Controller
support".

The issue with the menu was that the additional variable was in the middle 
of the list of frame buffer devices.

Here is a snippet of the solution I propose without the not needed depend. 
I cook a v2 patch just now.
