* thermal: Make sysfs attributes of cooling devices default attributesMatthias Kaehlcke2015-03-051-20/+17
| | | | | | | | | Default attributes are created when the device is registered. Attributes created after device registration can lead to race conditions, where user space (e.g. udev) sees the device but not the attributes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | As soon as the interrupt has been enabled by devm_request_irq(), the interrupt routine may be called, depending on the current status of the hardware. However, at that point rcar_thermal_common hasn't been initialized complely yet.

| * thermal: exynos: Add TMU support for Exynos7 SoCAbhilash Kesavan2015-01-312-8/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add registers, bit fields and compatible strings for Exynos7 TMU (Thermal Management Unit). Following are a few of the differences in the Exynos7 TMU from earlier SoCs: - 8 trigger levels - Different bit offsets and more registers for the rising and falling thresholds. - New power down detection bit in the TMU_CONTROL register which does not update the CURRENT_TEMP0 when tmu power down is detected. - Change in bit offset for the NEXT_DATA field of EMUL_CON register. EMUL_CON register address has also changed. - INTSTAT and INTCLEAR registers present in earlier SoCs have been combined into one INTPEND register. The register address for INTCLEAR and INTPEND is also different. - Since there are 8 rising/falling interrupts as against at most 4 in earlier SoCs the INTEN bit offsets are different. - Multiple probe support which is handled by a TMU_CONTROL1 register (No support for this in the current patch). This patch adds special clock support required only for Exynos7. It also updates the "code_to_temp" prototype as Exynos7 has 9 bit code-temp mapping.

* | | netlink: make nlmsg_end() and genlmsg_end() voidJohannes Berg2015-01-181-5/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Contrary to common expectations for an "int" return, these functions return only a positive value -- if used correctly they cannot even return 0 because the message header will necessarily be in the skb. This makes the very common pattern of if (genlmsg_end(...) < 0) { ... } be a whole bunch of dead code. Many places also simply do return nlmsg_end(...); and the caller is expected to deal with it. This also commonly (at least for me) causes errors, because it is very common to write if (my_function(...)) /* error condition */ and if my_function() does "return nlmsg_end()" this is of course wrong. Additionally, there's not a single place in the kernel that actually needs the message length returned, and if anyone needs it later then it'll be very easy to just use skb->len there. Remove this, and make the functions void. This removes a bunch of dead code as described above. The patch adds lines because I did - return nlmsg_end(...); + nlmsg_end(...); + return 0; I could have preserved all the function's return values by returning skb->len, but instead I've audited all the places calling the affected functions and found that none cared. A few places actually compared the return value with <= 0 in dump functionality, but that could just be changed to < 0 with no change in behaviour, so I opted for the more efficient version. One instance of the error I've made numerous times now is also present in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't check for <0 or <=0 and thus broke out of the loop every single time. I've preserved this since it will (I think) have caused the messages to userspace to be formatted differently with just a single message for every SKB returned to userspace. It's possible that this isn't needed for the tools that actually use this, but I don't even know what they are so couldn't test that changing this behaviour would be acceptable.

These devices are either reported as a PCI device or an ACPI device. This device provides power limits, control states and optional temperature. This change implements minimal requirements to expose processor power limits which can be used during thermal power limiting. Power limits are exposed via an attribute group called "power_limits" under the device. The exported attributes are: power_limit_0_max_uw power_limit_1_max_uw power_limit_0_min_uw power_limit_1_min_uw power_limit_0_tmin_us power_limit_1_tmin_us power_limit_0_tmax_us power_limit_1_tmax_us power_limit_0_step_uw power_limit_1_step_uw Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
