| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renamed the MPC8568 MDS platform code to follow other 85xx boards. There isn't anything specific about the 8568 MDS code that wouldn't apply to another 85xx MDS system at this point. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Removed uccf_printk() and related functions, because they were just front-ends to printk(). Fixed some spacing and tabbing issues. Minor optimizations of some code. Changed the type of some variables to their proper type (mostly buffer descriptors). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | * | | | | [POWERPC] pseries: Enabling auto poweron after power is restored.Manish Ahuja2007-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During power outages, the UPS notifies the system for a shutdown. In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.

It provides voltage scaling and can use ACPI C3 state. That's curious. CPU will not change frequency on ACPI C3 when v1 is in use, but it will when v2 is used. Driver will return max frequency all the time if this isn't true for all processors. There is strange thing with mobile voltage. Looks like only Nehemiah (C3-M) supports it. Earlier processors have different mobile VRM (in docs), but I can't find any which is using it. Looks like all are using VRM 8.5. So fail for non Nehemiah with mobile VRM.

Voltage transitions will be done before or after frequency transition. That depends on direction of change. I don't know how to force conservative governor when voltage scaling is enabled, so there is only a warning for user. Minimal voltage is calculated in different way now because in this way more power is saved at lower multipliers.

Beta tested by Jorgen (jorgen (at) greven dot dk). Thanks! Based on documentation provided by Dave Jones (Thanks!) and C7 Eden datasheet available from www.via.com.tw. Looks like all these C7 Eden CPU's don't have P-states in BIOS. I know that 2 p-states is low, but Jorgen finds it usefull anyway because board is passive cooled. There are 3 different types of C7 processors (called brands): 0. C7-M - these processors can set any maultiplier between min and max, any voltage between min and max. 1. C7 - only min and max states are supported. Voltage is different for min and max states. 2. Eden - only min and max states are supported. Looks like this brand can only change multiplier. Voltage seems to be the same for min and max frequency. Signed-off-by: Rafal Bilski <rafalbilski@interia.pl> Signed-off-by: Dave Jones <davej@redhat.com>
