Patch from Lennert Buytenhek The cirrus ep93xx has 3 pl010 UARTs, while amba-pl010.c only allows for 2 by default. A while ago, I think we agreed on changing the 2 to 8, but I don't see this in 2.6.17 yet.

This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Patch from Andrew Victor This patch includes a number of updates to the AT91RM9200 serial driver. Changes include: 1. Conversion to a platform_driver. [Ivan Kokshaysky] 2. Replaced all references to AT91RM9200 with AT91. This driver can now also be used for the AT91SAM9216. 3. Allow TIOCM_LOOP to configure local loopback mode. 4. Cleaned up the 'read_status_mask' usage and interrupt handler code. [Chip Coldwell] 5. Suspend/resume support. [David Brownell] There are a few 'unused variable' warning when compiling this - I removed the new DMA support to keep this first patch simpler.

This fixes various odd things that missed update together with cpm_uart platform_device move. Unified resources names, restructurisation, etc. Also, addressed issue with recent phys/virt translation rework. Being cache-coherent, CPM2's do alloc_bootmem() for the console stuff, and it was used to treat console buffer descriptor mapping 1:1 (as in CPM1 case), which is definitely wrong.

A bug report from Gerd Hoffmann has highlighted that unconditionally enabling the transmit interrupt at the end of console writes is very bad. In Gerd's case, it causes the test for buggy UARTs to give false positives, incorrectly identifying ports as buggy when they are not. Moreover, if we unconditionally enable the interrupt, and the port is sharing it's interrupt with other ports, there is the very real possibility that we'll cause an interrupt storm. (Not all ports use OUT2 as an interrupt mask.) Hence, revert part of f91a3715 and all of f5968b37 until a better solution can be found. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Current address translation methods can produce wrong results, because virt_to_bus and vice versa may not produce correct offsets on dma-allocated memory. The right way is, while tracking both phys and virt address of the window that has been allocated for boffer descriptors, and use those numbers to compute the offset and make translation properly.

This ugly hack add support for Siemens MC45 PCMCIA GPRS card (which is identical to Possio GCC, and which is offered by one of our local GPRS providers). Card has unfortunate feature that after poweron oxcf950 chip is fully powered and works, but attached MC45 modem is powered down :-( There is a special sequence (which takes 1 sec :-( ) to poweron MC45 (and after MC45 powers on, it takes more than 2 secs until firmware fully boots...) which needs to be executed after all powerons. I'm really not familiar with PCMCIA subsystem, so I have no idea whether I should issue request_region() on rest of oxcf950 address range (0-7 is UART, 8-F are special configuration registers), or how this should be better integrated with PM system and so on - I just put it in same place where another hack already lived... Card uses 18.432MHz XTAL, so to get it to work you must add lines below to the /etc/pcmcia/serial.opts. case "$MANFID-$FUNCID-$PRODID_1-$PRODID_2-$PRODID_3-$PRODID_4" in '030c,0003-2-GPRS-CARD--') SERIAL_OPTS="baud_base 1152000" ;; esac Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NDominik Brodowski <linux@dominikbrodowski.net>
