DMAENGINE: generic slave channel control v2
2010/7/21 Linus Walleij <linus.walleij(a)stericsson.com>: This adds an interface to the DMAengine to make it possible to reconfigure a slave channel at runtime. We add a few foreseen config parameters to the passed struct, with a void * pointer for custom per-device or per-platform runtime slave data. BT... 23 Jul 2010 00:34

[PATCH 0/3] drivers:staging:ti-st: patches
From: Pavan Savoy <pavan_savoy(a)ti.com> The following patches cleanup bit of a mess and also adds functionality to protocol drivers. with the 3rd patch now providing context to even the protocol drivers, the single device limit or support for multiple devices would be easier to implement. These patches depend on... 22 Jul 2010 07:02

[PATCH 3/3] drivers:staging:ti-st: give proto drivers context
From: Pavan Savoy <pavan_savoy(a)ti.com> protocol drivers such as BT, FM and GPS when registering to ST now provide their own private data which they expect when their functions namely registration completed & receive are called. Also upon tty_close, set protos_registered count to 0, although all protocols are ma... 22 Jul 2010 07:02

[PATCH 1/3] drivers:staging:ti-st: smarten, reduce logs
From: Pavan Savoy <pavan_savoy(a)ti.com> Replace looping on the data buffers and printk-ing by print_hex_dump. Also replace most of the pr_info by pr_debug to reduce logging at default loglevels (7 in our case..)

[review patch 0/2] new driver: Nosy, a low-budget FireWire packet sniffer
Here is a (not so) new driver proposed for merge into the mainline: Nosy - turns a Texas Instruments PCILynx card into an IEEE 1394 (FireWire) bus analyzer This kernel driver is useful to reverse-engineer undocumented vendor-specific protocols and as an aid in IEEE 1394 application/ driver/ firm... 22 Jul 2010 07:02

[review patch 1/2] firewire: new driver: nosy - IEEE 1394 traffic sniffer
This adds the traffic sniffer driver for Texas Instruments PCILynx/ PCILynx2 based cards. The use cases for nosy are analysis of nonstandard protocols and as an aid in development of drivers, applications, or firmwares. This comparably small kernel driver sets up packet reception DMA in the special snoop mode o... 22 Jul 2010 07:02
