2009-12-11tty: sdio_uart: Style fixesAlan Cox
Running the current code through checkpatch shows a few bits of noise mostly but not entirely from before the changes. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty: sdio_uart: Fix termios handlingAlan Cox
Switching between two non standard baud rates fails because of the cflag test. Do as we did elsewhere and just kill the "optimisation". Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty: sdio_uart: Switch to the open/close helpersAlan Cox
Gets us proper tty semantics, removes some code and fixes up a few corner case races (hangup during open etc) Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11sdio_uart: Move the open lockAlan Cox
When we move to the tty_port logic the port mutex will protect open v close v hangup. Move to this first in the existing open code so we have a bisection point. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11sdio_uart: refcount the tty objectsAlan Cox
The tty can go away underneath us, so we must refcount it. Do the naïve implementation initially. We will worry about startup shortly. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11sdio_uart: Fix oops caused by the previous changesetNicolas Pitre
Now... testing reveals that the very first patch "sdio_uart: use tty_port" causes a segmentation fault in sdio_uart_open(): Unable to handle kernel NULL pointer dereference at virtual address 00000084 pgd = dfb44000 [00000084] *pgd=1fb99031, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] PREEMPT last sysfs file: /sys/devices/platform/mvsdio/mmc_host/mmc0/mmc0:f111/uevent Modules linked in: CPU: 0 Not tainted (2.6.32-rc5-next-20091102-00001-gb36eae9 #10) PC is at sdio_uart_open+0x204/0x2cc [...] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11sdio_uart: use tty_portAlan Cox
Add a tty_port object to the sdio uart. For the moment just begin using the tty field of the port, as this is the critical one to clean up. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty_port: Move hupcl handlingAlan Cox
Move the HUCPL handling from the end of close_port_start to the beginning of close_port_end. What this actually does is change the ordering from port shutdown port->dtr_rts to port->dtr_rts port shutdown Some hardware drops the physical connection on shutdown so we must perform the port operations before the shutdown.

2009-12-11Serial: Do not read IIR in serial8250_start_tx when UART_BUG_TXENIan Jackson
Do not read IIR in serial8250_start_tx when UART_BUG_TXEN Reading the IIR clears some oustanding interrupts so it is not safe. Instead, simply transmit immediately if the buffer is empty without regard to IIR.

2009-12-11Serial: pxa: work around Errata #75Uwe Kleine-König
Intel(R) PXA27x Processor Family Specification Update (Nov 2005) says: E75. UART: Baud rate may not be programmed correctly on back-to-back writes. Problem: When programming the Divisor Latch registers, Low and High (DLL and DLH), with back-to-back writes, the second register write may not take effect. The result is an incorrect baud rate. Workaround: After programming the first Divisor Latch register, read and verify it before programming the second Divisor Latch register. This was hit when changing the baud rate from 115200 to 9600 while receiving characters at 9600 Bd. And fixed indention of some comments nearby.

Here I've kept the selection of IIO_SW_RING separate from IIO_TRIGGER as it will go away fairly shortly when the ring buffer type becomes configurable on a per device basis, whereas the IIO_TRIGGER select will remain.

Adjusts the signal levels reported by the wlags49_h2 and wlags49_h25 staging drivers. With the constants supplied by Agere the signal levels are always poor, even in close proximity to the AP. The signals are now measured with a real device. 100% for close proximity to the AP, 0% for the noice floor. Now the levels shown by the NetworkManager gauge make sense. Some magic numbers in the related code are replaced by the correct constants from the wireless extension interface (wireless.h).
