2007-07-20[CELL] cbe_cpufreq: reorganize codeChristian Krafft6-188/+309
This patch reorganizes the code of the driver into three files. Two cbe_cpufreq_pmi.c and cbe_cpufreq_pervasive.c care about hardware. cbe_cpufreq.c contains the logic. There is no changed behaviour, except that the PMI related function is now located in a seperate module cbe_cpufreq_pmi. This module will be required by cbe_cpufreq, if CONFIG_CBE_CPUFREQ_PMI has been set. Signed-off-by: Christian Krafft <krafft@de.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2007-07-20[CELL] cbe_cpufreq: fix minor issuesChristian Krafft1-18/+40
Minor issues have been fixed: * added a missing call to of_node_put() * signedness of a function parameter * added some line breaks * changed global pmi_frequency_limit to a per node pmi_slow_mode_limit array Signed-off-by: Christian Krafft <krafft@de.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2007-07-20[CELL] cbe_cpufreq: fix initializationChristian Krafft1-12/+8
This patch fixes the initialization of the cbe_cpufreq driver. The code that initializes the PMI related functions was called per cpu: * registering cpufreq notifier block * registering a pmi handler This ends in a bug that the notifier block gets called in an endless loop. The initialization code is being put to the module init code path by this patch. This way it only gets called once.

2007-07-20[CELL] pmi: remove support for mutiple devices.Christian Krafft2-51/+36
The pmi driver got simplified by removing support for multiple devices. As there is no more than one pmi device per maschine, there is no need to specify the device for listening and sending messages. This way the caller (cbe_cpufreq) doesn't need to scan the device tree. When registering the handler on a board without a pmi interface, pmi.c will just return -ENODEV. The patch that fixed the breakage of cell_defconfig has been broken out of the earlier version of this patch. So this is the version that applies cleanly on top of it.

2007-07-20xen: disable vdso "nosegneg" on native bootRoland McGrath4-6/+29
One of the nice ideas behind paravirt is that CONFIG_XEN=y can be included in a standard configuration and be no worse for native booting than as a Xen guest. The glibc feature that supports the vDSO "nosegneg" note is designed specifically to make this easy. You just have to flip one bit at boot time. This patch makes Xen flip the bit, so a CONFIG_XEN=y kernel on bare hardware does not make glibc use the less-optimized library builds.

2007-07-20sh: update r2d defconfig and fix SH7751R pci compliationMagnus Damm2-3/+4
This patch updates the r2d board support in a few ways: - CPU_SUBTYPE_SH7751R is selected in the defconfig to play well with the r2d board Kconfig entry. Without this the defconfig results in no board enabled. - Enable EARLY_PRINTK. - Enable SH_STANDARD_BIOS - this works well for early printk on the r2d board. - Add "earlyprink=bios" to the cmdline for early serial port output by default. - CONFIG_SUBTYPE_SH7751R support is added to the sh-specific pci makefile.

2007-07-20sh: cpufreq: clock framework support.Paul Mundt2-135/+81
This gets the SH cpufreq working again. We follow the changes in the AVR32 implementation for wrapping in to the clock framework. CPUs that wish to use this are required to define rate rounding primitives in order to satisfy clk_round_rate(). This works well enough for the common case, though we should look at unifying this driver across all of the platforms that implement clock framework support in one capacity or another.
