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: NAlan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

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: NAlan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

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: NAlan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

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: NAlan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

In a few places, sdio_uart_irq() is called directly instead of waiting for the actual interrupt to be raised and the SDIO IRQ thread scheduled in order to reduce latency. However, some interaction with the tty core may end up calling us back (serial echo, flow control, etc.) creating two issues: - the host lock gets claimed twice from the same thread causing a deadlock; - the same direct calls to sdio_uart_irq() may be performed causing unexpected reentrancy into the IRQ handler. This patch handles both of those issues. Signed-off-by: NNicolas Pitre <npitre@mvista.com> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>
