First move of items out of include/asm-arm/plat-s3c* to their new homes under arch/arm/plat-s3c/include/plat and arch/arm/plat-s3c24xx/include/plat directories.

2008-10-02serial: sh-sci: Dynamic clock management depends on HAVE_CLK.Paul Mundt2-31/+16
Presently this is conditionalized on sh, and disabled for sh64. Now that SH-5 ties in to the clock framework, the sh64 exception can be dropped. Additionally, ARM will want to use the same hooks once SH-Mobile G3 grows clock framework support, so switch these paths over to HAVE_CLK now. Once the H8 and ARM sh-sci users hook up HAVE_CLK, the driver can be switched over to having an outright dependency on it and the ifdefs can go away. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-10-02[ARM] 5250/1: unbalanced enable_irq() for serial_ks8695.c fixDick Hollenbeck1-9/+52
The function ks8695uart_set_termios() would cause an unbalanced enable_irq() generated message to be printk()ed. This is because there was no book keeping support to remember if the calls to enable_irq() and disable_irq() were balanced for the modem control irq.

2008-09-23atmel_serial: update the powersave handler to match serial coreAnti Sullin1-13/+19
This problem seems to be unnoticed so far: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b3b708fa2780cd2b5d8266a8f0c3a1cab364d4d2 has changed the serial core behavior to not to suspend the port if the device is enabled as a wakeup source. If the AT91 system goes to slow clock mode, the port should be suspended always and the clocks should be switched off. The patch attached updates the atmel_serial driver to match the changes in serial core. Also, the interrupts are disabled when the clock is disabled. If we disable the clock with interrupts enabled, an interrupt may get stuck. If this is the DBGU interrupt, this blocks the OR logic at system controller and thus all other sysc interrupts.

2008-09-038250: improve workaround for UARTs that don't re-assert THRE correctlyWill Newton2-4/+13
Recent changes to tighten the check for UARTs that don't correctly re-assert THRE (01c194d9278efc15d4785ff205643e9c0bdcef53: "serial 8250: tighten test for using backup timer") caused problems when such a UART was opened for the second time - the bug could only successfully be detected at first initialization. For users of this version of this particular UART IP it is fatal. This patch stores the information about the bug in the bugs field of the port structure when the port is first started up so subsequent opens can check this bit even if the test for the bug fails. David Brownell: "My own exposure to this is that the UART on DaVinci hardware, which TI allegedly derived from its original 16550 logic, has periodically gone from working to unusable with the mainline 8250.c ... and back and forth a bunch. Currently it's "unusable", a regression from some previous versions. With this patch from Will, it's usable."

2008-09-02imx serial: fix rts handling for non imx1 based hardwareMarc Kleine-Budde1-1/+1
The interrupt handler for muxed interrupts (imx2/imx3) was calling the rts handling subroutine if the RTSS bit was set. (Which indicates the status of the RTS line), leading to an interrupt flood on RTS bit low. This patch fixes the problem by looking at the RTSD bit instead, indicating a change in the RTS line.

CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if the end of a tuple chain is reached. As at least one PCMCIA driver relies on matching this return value, replace it with -ENOSPC which is now uniquely used for this purpose within the in-kernel pcmcia subsystem.
