Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

* SIIG serial cards have an PCI interface chip which also controls

* (except cards equiped with 4 UARTs) and initial clocking settings
* are stored in the EEPROM chip. It can cause problems because this
* version of serial driver doesn't support differently clocked UART's
* on single PCI card. To prevent this, initialization functions set
* high frequency clocking for all UART's on given card. It is safe (I
* hope) because it doesn't touch EEPROM settings to prevent conflicts
* with other OSes (like M$ DOS).
*
* SIIG support added by Andrey Panin <pazke@donpac.ru>, 10/1999
*
* There is two family of SIIG serial cards with different PCI
* interface chip and different configuration methods:
* - 10x cards have control registers in IO and/or memory space;
* - 20x cards have control registers in standard PCI configuration space.
*
* Note: some SIIG cards are probed by the parport_serial object.

[PATCH] 8250_pci.c: add comment about enum sorting order Signed-off-by: Russell King <rmk@arm.linux.org.uk>

* This table is sorted by (in order): baud, bt, bn, n.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
2005-04-16 22:20:36 +00:00
* Please note: in theory if n = 1, _bt infix should make no difference.
* ie, pbn_b0_1_115200 is the same as pbn_b0_bt_1_115200
