net/stmmac: Move "#include <linux/platform_device.h>" to linux/stmmac.h stmmac.h uses struct platform_device and doesn't include <linux/platform_device.h>. Whereas drivers/net/stmmac/stmmac.h includes it, but doesn't directly use it. And so we get following compilation warning while using this file: warning: ‘struct platform_device’ declared inside parameter list This patch includes <linux/platform_device.h> in linux/stmmac.h and removes it from drivers/net/stmmac/stmmac.h Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Acked-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

stmmac: unify MAC and PHY configuration parameters (V2) Prior to this change, most PHY configuration parameters were passed into the STMMAC device as a separate PHY device. As well as being unusual, this made it difficult to make changes to the MAC/PHY relationship. This patch moves all the PHY parameters into the MAC configuration structure, mainly as a separate structure. This allows us to completely ignore the MDIO bus attached to a stmmac if desired, and not create the PHY bus. It also allows the stmmac driver to use a different PHY from the one it is connected to, for example a fixed PHY or bit banging PHY. Also derive the stmmac/PHY connection type (MII/RMII etc) from the mode can be passed into <platf>_configure_ethernet. STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git provides several examples how to use this new infrastructure (that actually is easier to maintain and clearer).

stmmac: add CSR Clock range selection This patch adds the CSR Clock range selection. Original patch from Johannes Stezenbach fixed the CSR in the stmmac_mdio.

stmmac: new descriptor field for the driver's platform The new enh_desc is used for selecting the enhanced descriptors structure. There are several scenarios; some chips (mac10/100 or gmac) want to use the enhanced descriptors; others want the normal ones. For example, on ST platforms: MAC10/100 uses the normal desc structure and the GMAC uses the enhanced one. It can be useful to get this information from the platform. This could also be decided at run-time looking at the chip's ID number; but it could happen that chips with the same ID want to use different descriptor structure.

stmmac: consolidate and tidy-up the COE support The first version of the driver had hard-coded the logic for handling the checksum offloading. This was designed according to the chips included in the STM platforms where: o MAC10/100 supports no COE at all. o GMAC fully supports RX/TX COE. This is not good for other chip configurations where, for example, the mac10/100 supports the tx csum in HW or when the GMAC has no IPC. Thanks to Johannes Stezenbach; he provided me a first draft of this patch that only reviewed the IPC for the GMAC devices. This patch also helps on SPEAr platforms where the MAC10/100 can perform the TX csum in HW. Thanks to Deepak SIKRI for his support on this. In the end, GMAC devices for STM platforms have a bugged Jumbo frame support that needs to have the Tx COE disabled for oversized frames (due to limited buffer sizes). This information is also passed through the driver's platform structure.

stmmac: Allow SOCs to use Store forward mode eventhough tx_coe is 0. (V2) This patch adds new field 'force_sf_dma_mode' to plat_stmmacenet_data struct to allow users to specify if they want to use force store forward eventhough tx_coe is not available in hw. without this flag stmmac driver will use cut-thru mode not use store-forward mode.

stmmac: add init/exit callback in plat_stmmacenet_data struct This patch adds in the plat_stmmacenet_data the init and exit callbacks that can be used for invoking specific platform functions. For example, on ST targets, these call the PAD manager functions to set PIO lines and syscfg registers. The patch removes the stmmac_claim_resource only used on STM Kernels as well.
