A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Unfortunately, pcmcia_dev_present() returns false when a device is suspended, so checking this on resume does not work too well. Omit this test. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

asm/serial.h is supposed to contain the definitions for the architecture specific 8250 ports for the 8250 driver. It may also define BASE_BAUD, but this is the base baud for the architecture specific ports _only_. Therefore, nothing other than the 8250 driver should be including this header file. In order to move towards this goal, here is a patch which removes some of the more obvious incorrect includes of the file.

The patch below is necessary for 115200 baud on an OMAP1510 internal UART. It's been in the linux-omap tree for some time and with it applied to a vanilla Linus git tree the serial console on the Amstrad Delta (which is OMAP1510 based and whose initial bootloader runs at 115200) works fine (it doesn't without it).

I think register ranges obviously need to be claimed/released for all UARTs including those with UPIO_MEM32 and UPIO_TSI iotype. Also, serial8250_request_rsa_resources() returns false positives with UPIO_MEM32, UPIO_AU, and UPIO_TSI iotype -- I don't think this makes any sense.

Mauro Ziliani reports that this card has a higher clock rate. Rather than tweak the 8250 driver to handle this, add a quirk to pass the correct clock rate to the driver. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

According to the existing code, Nokia only make single-port cards, but are detected as multi-port cards. Handle this in roughly the same way via the config quirk - forcing it to be a real single port card (info->multi=0) changes the way we allocate the IO memory, which might stop the card working.

Move IBM quirk handling into its own quirk entry. Note that doing quirk handling after we've registered the ports is racy, but since I don't know if moving this will have an undesired effect, it's probably better to leave where it is. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Some quirks we will introduce next apply to (eg) all cards of one manufacturer. Therefore, we need a way to list these in the quirk table - use ~0 - this is not a possible device ID value. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

由 Russell King 提交于
- rename multi_id table to serial_quirk / quirks[] - use named initialisers - store a pointer to the quirk table in the serial_info structure so we can use the quirk table entry later. - apply multi-port quirk after the multi-port guessing code, but only if it's != -1.

m32r_sio re-uses a custom defined BASE_BAUD from asm/serial.h, and replaces SERIAL_PORT_DFNS with its own driver private copy. Since asm/serial.h is supposed to define 8250-based ports using these symbols, this isn't a sane idea. Hence, eliminate asm/serial.h from m32r_sio.c.

MSI is defined to be 32-bit write. The 5706 does 64-bit MSI writes with byte enables disabled on the unused 32-bit word. This is legal but causes problems on the AMD 8132 which will eventually stop responding after a while. Without this patch, the MSI test done by the driver during open will pass, but MSI will eventually stop working after a few MSIs are written by the device. AMD believes this incompatibility is unique to the 5706, and prefers to locally disable MSI rather than globally disabling it using pci_msi_quirk. Update version to 1.4.45.

If you send a priority character (as is done for flow control) then the tty driver can either have its own method for "jumping the queue" or the characrer can be queued normally. In the latter case we call the write method but without the atomic_write_lock taken elsewhere. Make this consistent. Note that the send_xchar method if implemented remains outside of the lock as it can jump ahead of a current write so must not be locked out by it.

Introduce the disable_irq_nosync_lockdep_irqsave() and enable_irq_lockdep_irqrestore() APIs. These are needed for NE2000; basically NE2000 calls disable_irq and enable_irq as locking against the IRQ handler, but both in cases where interrupts are on and off. This means that lockdep needs to track the old state of the virtual irq flags on disable_irq, and restore these at enable_irq time.

If your driver implements "break on" and "break off" this ensures you won't get multiple overlapping requests or requests in parallel. If your driver has its own break handling then its still your problem as the driver author.
