MIPS: MTX-1: Make au1000_eth probe all PHY addresses

2011-06-26T16:47:01Z

commit bf3a1eb85967dcbaae42f4fcb53c2392cec32677 upstream. When au1000_eth probes the MII bus for PHY address, if we do not set au1000_eth platform data's phy_search_highest_address, the MII probing logic will exit early and will assume a valid PHY is found at address 0. For MTX-1, the PHY is at address 31, and without this patch, the link detection/speed/duplex would not work correctly.

MIPS: MTX-1: Fix PCI on the MeshCube and related boards

2010-08-02T17:30:22Z

commit 98a0f86a54bb195c28ae1ccb5a5f5cda12cf7121 upstream. This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1: Use linux gpio api." (bb706b28bbd647c2fd7f22d6bf03a18b9552be05) which broke PCI bus operation. The problem is caused by alchemy_gpio2_enable() which resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected to GPIO2 and they obviously do not to like the reset. Since GPIO2 is correctly initialized by the boot monitor (YAMON) it is not necessary to call this function, so just remove it. Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid problems in case gpiolib gets initialized after PCI. And since alchemy gpio_set_value() calls au_sync() we don't have to au_sync() again later.

MIPS: DB1200: PCMCIA card detection must not be auto-enabled.

2010-04-30T19:52:43Z

Same issues as SD card detection: One of both is always triggering and the handlers take care to shut it up and enable the other. To avoid messages about "unbalanced interrupt enable/disable" they must not be automatically enabled when initally requested. This was not an issue with the db1200_defconfig due to fortunate timings; on a build without network chip support the warnings appear.

MIPS: Alchemy: DB1200: Remove custom wait implementation

2010-04-12T16:26:22Z

While playing with the out-of-tree MAE driver module, the system would panic after a while in the db1200 custom wait code after wakeup due to a clobbered k0 register being used as target address of a store op. Remove the custom wait implementation and revert back to the Alchemy- recommended implementation already set as default.

MIPS: Alchemy: use 36bit addresses for PCMCIA resources.

2010-02-27T11:53:43Z

On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus area. Currently, addresses at the far end of the 32bit area are assumed to belong to the PCMCIA area and fixed up to the real 36bit address before being passed to ioremap(). A previous commit enabled 64 bit physical size for the resource datatype on Alchemy and this allows to use the correct 36bit addresses when registering the PCMCIA sockets. This patch removes the 32-to-36bit address fixup and registers the Alchemy demo board pcmcia socket with the correct 36bit physical addresses. Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet card.
