| | | | | | | | | | | | | | | | | | | | | | | | | | Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols, it's time to get rid of them: Move some of the platform devices to the boards which can use them, Rename a few (unused) constants in the header, Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally delete them altogether from the Alchemy Kconfig file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the last hardcoded base address from the au1000_eth driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have various bootloaders for Exynos4210 machines. Some of they set the ARM core frequency at boot time even when the boot is a resume from suspend-to-RAM. Such changes may create inconsistency in the data of CPUFREQ driver and have incurred hang issues with suspend-to-RAM. This patch enables to save and restore CPU frequencies with pm-notifier and sets the frequency at the initial (boot-time) value so that there wouldn't be any inconsistency between bootloader and kernel. This patch does not use CPUFREQ's suspend/resume callbacks because they are syscore-ops, which do not allow to use mutex that is being used by regulators that are used by the target function. This also prevents any CPUFREQ transitions during suspend-resume context, which could be dangerous at noirq-context along with regulator framework.

| * | [CPUFREQ] e_powersaver: Allow user to lower maximum voltageRafał Bilski2011-10-261-0/+18

One of the lessons learned from Adaptive Powersaver is that voltage values returned by processor are for worst case scenario. But required voltage is changing with CPU temperature. And even processors produced in the same batch can have different minimum voltage necessary for stable work at specified frequency. On Elonex Webbook, once system starts, temperature never drops below 48 deg. C. Loading module after systems start allows user to lower CPU voltage and still have stable system. Sadly C7 doesn't allow code to set frequency or voltage from outside limits. If you ask it to set voltage lower then minimum it will ignore you. Thats why it isn't possible to change minimum voltage for minimum frequency too. Changing maximum voltage on Elonex Webbook leads to very good results. Looks like VIA C7 1.6GHz 1084mV can safetly run at 892mV. This means 83% of orginal value. If same percentage applies to power generated it means 12.5W in the place of 15W. Not much, but it is better then nothing. Only C7-M makes it possible. If voltage is too low by 16mV or more you will experience kernel panic. If voltage is too low by 32mV or more you will experience system freeze. Signed-off-by: Rafał Bilski <rafalbilski@interia.pl> Signed-off-by: Dave Jones <davej@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems are using 1,2Ghz@844mV processors running at 600MHz@796mV. Try to detect such systems and don't touch anything on it. If CPU doesn't have P-States in BIOS it should run at maximum frequency. Allow user to bypass checks by means of two new options. Don't set frequency to maximum on module unloading to avoid bada boom. It is also possible that some processors may have incorrect values in min/max registers caused by error in manufacturing process. Probably it would be BIOS job to set them to right frequency and P-States tables would have correct values inside. Two additional sanity checks for voltage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some clocks may be force enabled when we probe the driver, but they need to be turned off by default so we have a known state. We call this the register initialization function if we need more stuff in there in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Module IRQs may still be disabled by DPM at the time the TWL6030 ISR runs, causing handle_simple_irq() to silently do nothing. This may result in missing TWL RTC alarm wakeups, for example, since the RTC child module ISR is not called to ack the IRQ. Disable the TWL6030 IRQ during suspend, enable it at DPM resume time, at which time the child module IRQs will be re-enabled.

Although the irq_desc and lock are different, LOCKDEP treats these as equivalent, presumably due to problems that can be incurred when locking more than one irq_desc, so best to avoid this. Suspend/resume actions implemented as PM notifiers to avoid touch the TWL core for this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AB3550 never passed the prototype stage. Instead it was used as a precursor to AB5500 for testing basic building blocks used in that chip, since they had large similarities. Since AB3550 will not see the light of day in product form and since the prototypes are no longer used, let's delete the driver and any references to it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The analog baseband chip ab5500 is a multi functional chip containing regulators, charging, gpio, USB and accessory detect. It also contain various multimedia functionalities like digital encoder and audio codec. The core driver added with this patch provides register access via i2c via PRCMU. Event handling implemented as irq_chip will come in future patches since it depends on PRCMU functionality not yet implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Intel MSIC chip found on Intel Medfield platforms. This chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The driver creates platform device for each subdevice. We also provide an MSIC register access API which should replace the more generic SCU IPC interface currently used. Existing drivers can choose whether they convert to this new API or stick with the SCU IPC interface.
