pch_uart: Add uart_clk selection for the MinnowBoard

2013-07-22T01:21:23Z

commit 29692d05647cb7ecea56242241f77291d5624b95 upstream. Use DMI_BOARD_NAME to determine if we are running on a MinnowBoard and set the uart clock to 50MHz if so. This removes the need to pass the user_uartclk to the kernel at boot time. Signed-off-by: Darren Hart Cc: Jiri Slaby Cc: "H.

Revert "serial: 8250_pci: add support for another kind of NetMos Technology PCI 9835 Multi-I/O Controller"

2013-07-13T18:42:26Z

commit 828c6a102b1f2b8583fadc0e779c46b31d448f0b upstream. This reverts commit 8d2f8cd424ca0b99001f3ff4f5db87c4e525f366. As reported by Stefan, this device already works with the parport_serial driver, so the 8250_pci driver should not also try to grab it as well.

tty: Reset itty for other pty

2013-07-13T18:42:26Z

commit 64e377dcd7d75c241d614458e9619d3445de44ef upstream. Commit 19ffd68f816878aed456d5e87697f43bd9e3bd2b ('pty: Remove redundant itty reset') introduced a regression whereby the other pty's linkage is not cleared on teardown. This triggers a false positive diagnostic in testing. Properly reset the itty linkage. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

Both tiny fixes, but needed" * tag 'tty-3.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: tty: Fix transient pty write() EIO tty/vt: Return EBUSY if deallocating VT1 and it is busy

parisc: fix serial ports on C8000 workstation

2013-06-18T18:29:07Z

The C8000 workstation (64 bit kernel only) has a somewhat different serial port configuration than other models. Thomas Bogendoerfer sent a patch to fix this in September 2010, which was now minimally modified by me. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Helge Deller

tty: Fix transient pty write() EIO

2013-06-17T19:37:29Z

Commit 699390354da6c258b65bf8fa79cfd5feaede50b6 ('pty: Ignore slave pty close() if never successfully opened') introduced a bug with ptys whereby a write() in parallel with an open() on an existing pty could mistakenly indicate an I/O error. Only indicate an I/O error if the condition on open() actually exists.

tty/vt: Return EBUSY if deallocating VT1 and it is busy

2013-06-17T19:37:29Z

Commit 421b40a6286e ("tty/vt: Fix vc_deallocate() lock order") changed the behavior when deallocating VT 1. Previously if trying to deallocate VT1 and it is busy, we would return EBUSY. The commit changed this to return 0 (success). This commit restores the old behavior.

Revert "serial: 8250: Make SERIAL_8250_RUNTIME_UARTS work correctly"

2013-06-03T17:08:28Z

This reverts commit cfcec52e9781f08948c6eb98198d65c45be75a70. This regresses a longstanding behaviour on X86 systems, which end up with PCI serial ports moving between ttyS4 and ttyS0 when you bisect to opposite sides of this commit, resulting in the need to constantly modify the console setting in order to bisect across it. Please revert, we can work on solving this for ARM platforms in a less disruptive way. Signed-off-by: Kyle McMartin Cc: Karthik Manamcheri Signed-off-by: Greg Kroah-Hartman
