[PATCH 0/3] ARM: OMAP2+: Remove remaining unused legacy code

[PATCH 0/3] ARM: OMAP2+: Remove remaining unused legacy code

[Javier Martinez Canillas]

Now that OMAP2+ board files are scheduled for removal for v3.14
there is unused code that was only used by legacy platform code
and can be removed.

This patch-set depends on the series:

[PATCH 00/12] Drop omap3 board files and make mach-omap2 boot in DT only mode

and is composed of the following patches:

[PATCH 1/3] ARM: OMAP2+: Remove legacy smsc911x and smc91x GPMC
[PATCH 2/3] ARM: OMAP2+: Remove unnecesary include in GPMC driver
[PATCH 3/3] ARM: OMAP2+: Remove legacy board-flash.c

Best regards,
Javier

[PATCH 1/3] ARM: OMAP2+: Remove legacy smsc911x and smc91x GPMC support

[Javier Martinez Canillas]

When connecting an ethernet chip to the GPMC, such as smc91x
or smsc911x, a GPIO has to be requested to be used as an IRQ
and also the IO memory for a GPMC chip-select.

When booting with DT the chip-select allocation is handled
in a generic manner in the GPMC driver and the GPIO to IRQ
mapping is made by the DT core so this code is not needed
anymore now that mach-omap2 related boards are DT-only.

[PATCH 2/3] ARM: OMAP2+: Remove unnecesary include in GPMC driver

[Javier Martinez Canillas]

The GPMC driver includes arch/arm/mach-omap2/common.h but
does not use anything on that header so it can be removed.

[PATCH 3/3] ARM: OMAP2+: Remove legacy board-flash.c

[Javier Martinez Canillas]

Legacy board files in mach-omap2 used the helper functions
board_{nor,nand,onenand}_init() to initialize the flash
devices attached to the GPMC.

With Device Tree booting the initialization is handled by
the GPMC driver gpmc_probe_*_child() functions so this
code is not needed anymore now that OMAP2+ is DT-only.

[PATCH 0/3] ARM: OMAP2+: Remove remaining unused legacy code

[Tony Lindgren]

* Javier Martinez Canillas <javier.martinez@collabora.co.uk> [131129 11:20]:
> Now that OMAP2+ board files are scheduled for removal for v3.14
> there is unused code that was only used by legacy platform code
> and can be removed.
> 
> This patch-set depends on the series:
> 
> [PATCH 00/12] Drop omap3 board files and make mach-omap2 boot in DT only mode
> 
> and is composed of the following patches:
> 
> [PATCH 1/3] ARM: OMAP2+: Remove legacy smsc911x and smc91x GPMC
> [PATCH 2/3] ARM: OMAP2+: Remove unnecesary include in GPMC driver
> [PATCH 3/3] ARM: OMAP2+: Remove legacy board-flash.c

Thanks looks good to me. I'll wait for -rc3 to get tagged and then
apply all the pending mach-omap2 device tree conversion patches
against it including these.

Regards,

Tony
