2013-01-18net: ethernet: davinci_cpdma: Add boundary for rx and tx descriptorsMugunthan V N4-13/+57
When there is heavy transmission traffic in the CPDMA, then Rx descriptors memory is also utilized as tx desc memory looses all rx descriptors and the driver stops working then. This patch adds boundary for tx and rx descriptors in bd ram dividing the descriptor memory to ensure that during heavy transmission tx doesn't use rx descriptors. This patch is already applied to davinci_emac driver, since CPSW and davici_dmac shares the same CPDMA, moving the boundry seperation from Davinci EMAC driver to CPDMA driver which was done in the following commit commit 86d8c07ff2448eb4e860e50f34ef6ee78e45c40c Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue Jan 3 05:27:47 2012 +0000 net/davinci: do not use all descriptors for tx packets The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli3-4/+4
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.

2012-11-14cpsw: simplify the setup of the register pointersRichard Cochran1-139/+103
Instead of having a host of different register offsets in the device tree, this patch simplifies the CPSW code by letting the driver set the proper register offsets automatically, based on the CPSW version.

2012-11-14net: cpsw: Add parent<->child relation support between cpsw and mdioVaibhav Hiremath1-2/+14
CPGMAC SubSystem consist of various sub-modules, like, mdio, cpdma, cpsw, etc... These sub-modules are also used in some of Davinci family of devices. Now based on requirement, use-case and available technology nodes the integration of these sub-modules varies across devices. So coming back to Linux net driver, currently separate and independent platform devices & drivers for CPSW and MDIO is implemented. In case of Davinci they both has separate control, from resources perspective, like clock. In case of AM33XX, the resources are shared and only one register bit-field is provided to control module/clock enable/disable, makes it difficult to handle common resource. So the solution here implemented in this patch is, Create parent<->child relationship between both the drivers, making CPSW as a parent and MDIO as its child and enumerate all the child nodes under CPSW module. Both the drivers will function exactly the way it was operating before, including runtime-pm functionality. No change is required in MDIO driver (for that matter to any child driver). As this is only supported during DT boot, the parent<->child relationship is created and populated in DT execution flow. The only required change is inside DTS file, making MDIO as a child to CPSW node.

2012-11-14net: davinci_mdio: Fix typo mistake in calling runtime-pm apiVaibhav Hiremath1-1/+1
By mistake (most likely a copy-paste), instead of pm_runtime_get_sync() api, driver is calling pm_runtime_put_sync() api in resume callback function. The bug was introduced by commit id (ae2c07aaf74: davinci_mdio: runtime PM support). Now, the reason why it didn't impact functionality is, the patch has been tested on AM335x-EVM and BeagleBone platform while submitting; and in case of AM335x the MDIO driver doesn't control the module enable/disable part, which is handled by CPSW driver.
