* stmmac: make platform drivers depend on their associated SoCPeter Robinson2016-06-011-7/+7
| | | | | | | | | There's not much point, except compile test, enabling the stmmac platform drivers unless their actual SoC is enabled. They're not useful without it. Signed-off-by: Peter Robinson <pbrobinson@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* stmmac: add ipq806x glue layerMathieu Olivari2015-05-301-0/+14
| | | | | | | | | | | The ethernet controller available in IPQ806x is a Synopsys DesignWare Gigabit MAC IP core, already supported by the stmmac driver. This glue layer implements some platform specific settings required to get the controller working on an IPQ806x based platform.

During this procedure we convert the module registration part to use module_*_driver() macros which makes code simplier. >From now on the driver consists three parts: core library, PCI, and platform drivers.

| | | | | | | | | | | This is a very old and often unused option to configure a bit in a register inside the DMA. This support should not stay under Koption and should be extended for new chips too.

| | | | | | | | | | | This patch removes all the Koptions added to build the glue-logic files for all different architectures: DWMAC_MESON, DWMAC_SUNXI, DWMAC_STI ... Nowadays the stmmac needs to be compiled on several platforms; in some case it very convenient to guarantee that its build is always completed with success on all the branches where the driver is present.

* net: Move MII out from under NET_CORE and hide itBen Hutchings2013-06-191-1/+0
| | | | | | | | | | | | | All drivers that select MII also need to select NET_CORE because MII depends on it. This is a bit ridiculous because NET_CORE is just a menu option that doesn't enable any code by itself. There is also no need for it to be a visible option, since its users all select it.

* stmmac: reorganize chain/ring modes removing KoptionsGiuseppe CAVALLARO2013-03-261-18/+0
| | | | | | | | | | | | | | Previously we had two Koptions to decide if the stmmac had to use either a ring or a chain to manage its descriptors. This patch removes the Kernel configuration options and it allow us to use the chain mode by passing a module option. Ring mode continues to be the default. Also with this patch, it will be easier to validate the driver built and guarantee that all the two modes always compile fine.

* stmmac: fix driver built w/ w/o both pci and platf modulesGiuseppe CAVALLARO2012-06-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | The commit ba27ec66ffeb78cbf fixes the Kconfig of the driver when built as module allowing to select/unselect the PCI and Platform modules that are not anymore mutually exclusive. This patch fixes and guarantees that the driver builds on all the platforms w/ w/o PCI and when select/unselect the two stmmac supports. In case of there are some problems on both the configuration and the pci/pltf registration the module_init will fail. v2: set the CONFIG_STMMAC_PLATFORM enabled by default. I've just noticed that this can actually help on some configurations that don't enable any STMMAC options by default (e.g. SPEAr). v3: change printk level when do not register the driver.

* stmmac: add CHAINED descriptor mode support (V4)Giuseppe CAVALLARO2011-10-191-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch enhances the STMMAC driver to support CHAINED mode of descriptor. STMMAC supports DMA descriptor to operate both in dual buffer(RING) and linked-list(CHAINED) mode. In RING mode (default) each descriptor points to two data buffer pointers whereas in CHAINED mode they point to only one data buffer pointer. In CHAINED mode each descriptor will have pointer to next descriptor in the list, hence creating the explicit chaining in the descriptor itself, whereas such explicit chaining is not possible in RING mode. First version of this work has been done by Rayagond. Then the patch has been reworked avoiding ifdef inside the C code. A new header file has been added to define all the functions needed for managing enhanced and normal descriptors. In fact, these have to be specialized according to the ring/chain usage. Two new C files have been also added to implement the helper routines needed to manage: jumbo frames, chain and ring setup (i.e. desc3).
