2008-10-22sh: improve pinmux support for single direction pinsMagnus Damm3-23/+27
This patch improves the support for gpio pins that are hard wired to either input or output and lack control register association. A special force enum id is used to allow use without control register but still mark the gpio pin as input or output.

2008-10-22sh: use 10MHz VIO_CLK for ov772x on Migo-RMagnus Damm1-1/+4
Use a slower VIO_CKO clock frequency for the ov772x on Migo-R. This improves the camera picture quality on Panel Board V2.1. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-10-21sh: Update gpio_set_value() pin value handlingMagnus Damm1-1/+1
This patch updates the pinmux code to use the boolean value for the function gpio_set_value(). Without this patch values other than 0 and 1 will result in incorrect GPIO settings. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-10-21sh: Wire up oops reporting in the die notifier chain.Paul Mundt2-0/+3
Commit 3f5a54e371ca20b119b73704f6c01b71295c1714 ("ftrace: dump out ftrace buffers to console on panic") added an ftrace buffer dumper that hooks in to the die notifier chain and dumps out data in the oops path. Unfortunately SH supported ftrace but didn't support DIE_OOPS, so add that in and get it building again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-10-20kdump: make elfcorehdr_addr independent of CONFIG_PROC_VMCOREVivek Goyal1-0/+3
o elfcorehdr_addr is used by not only the code under CONFIG_PROC_VMCORE but also by the code which is not inside CONFIG_PROC_VMCORE. For example, is_kdump_kernel() is used by powerpc code to determine if kernel is booting after a panic then use previous kernel's TCE table. So even if CONFIG_PROC_VMCORE is not set in second kernel, one should be able to correctly determine that we are booting after a panic and setup calgary iommu accordingly. o So remove the assumption that elfcorehdr_addr is under CONFIG_PROC_VMCORE. o Move definition of elfcorehdr_addr to arch dependent crash files. (Unfortunately crash dump does not have an arch independent file otherwise that would have been the best place). o kexec.c is not the right place as one can Have CRASH_DUMP enabled in second kernel without KEXEC being enabled. o I don't see sh setup code parsing the command line for elfcorehdr_addr. I am wondering how does vmcore interface work on sh. Anyway, I am atleast defining elfcoredhr_addr so that compilation is not broken on sh.

2008-10-20container freezer: implement freezer cgroup subsystemMatt Helsley1-0/+2
This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

2008-10-20sh: Only build in gpio.o when CONFIG_GENERIC_GPIO is selected.Paul Mundt2-2/+4
The pinmux management is tied in to this code, while it is presently only used by platforms that select GENERIC_GPIO. The asm/gpio.h definitions are not referenced when GENERIC_GPIO is disabled, resulting in a build failure for all of the platforms that don't select it.

2008-10-04sh: More I/O routine overhauling.Paul Mundt6-232/+115
This tidies up a lot of the PIO/MMIO split. No in-tree platforms were making use of the MMIO overloading through the machvec (nor have any of them been in some time), so we just kill all of that off.
