2018-12-14regulator: mcp16502: add support for suspendAndrei.Stefanescu@microchip.com
This patch adds support for entering/resuming suspend states. It does this by setting the LPM pin of the PMIC. When suspending the PMIC will enter the Low-power mode when the LPM pin will be set to high. If the suspend target state is suspend-to-mem, the PMIC will transition to Hibernate mode, otherwise, if it is standby, it will remain in Low-power mode.

We may have the L-SIG length depending on the phy_data info type; add it to radiotap when we do. Move getting the phy_data out one layer up and the info type into it so we can use this data more generically. We need to call the iwl_mvm_rx_he() function for other reasons as well, so can't just combine all of that into something like iwl_mvm_parse_phy_data().

2018-12-14iwlwifi: mvm: change PHY data RX for HE radiotapShaul Triebitz
The firmware changed the PHY data API, so follow suit. Some data is now available even for HT/VHT frames, so the info type in the metadata was changed. This change isn't backwards compatible, but 1) the firmware with the old API was never released; 2) the only overlap in the info type field is from the old type of TB to the new of HT, so this basically just means that with older FW and newer driver the data will be considered missing. While at it, remove the extra code to set the LTF syms corresponding to the streams and use the data from the device instead - we don't really need this in any case other than when we have it from the device. As the new API gives use the spatial reuse 1-4 fields for trigger-based PPDUs, also expose that to radiotap.

2018-12-14iwlwifi: pcie: fix erroneous printSara Sharon
When removing the driver, the following flow can happen: 1. host command is in progress, for example at index 68. 2. RX interrupt is received with the response. 3. Before it is processed, the remove flow kicks in, and calls iwl_pcie_txq_unmap. The function cleans all DMA, and promotes the read pointer to 69. 4. RX thread proceeds with the processing, and is calling iwl_pcie_cmdq_reclaim, which will print this error: iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0), index 4 is out of range [0-256] 69 69.

2018-12-14iwlwifi: mvm: force TCM re-evaluation on TCM resumeAvraham Stern
When traffic load is not low or low latency is active, TCM schedules re-evaluation work so in case traffic stops TCM will detect that traffic load has become low or that low latency is no longer active. However, if TCM is paused when the re-evaluation work runs, it does not re-evaluate and the re-evaluation work is no longer scheduled. As a result, TCM will not indicate that low latency is no longer active or that traffic load is low when traffic stops. Fix this by forcing TCM re-evaluation when TCM is resumed in case low latency is active or traffic load is not low.

2018-12-14iwlwifi: move iwl_nvm_check_version() into dvmLuca Coelho
This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs.

2018-12-14PM / Domains: Propagate performance state updatesViresh Kumar
Currently a genpd only handles the performance state requirements from the devices under its control. This commit extends that to also handle the performance state requirement(s) put on the master genpd by its sub-domains. There is a separate value required for each master that the genpd has and so a new field is added to the struct gpd_link (link->performance_state), which represents the link between a genpd and its master. The struct gpd_link also got another field prev_performance_state, which is used by genpd core as a temporary variable during transitions. On a call to dev_pm_genpd_set_performance_state(), the genpd core first updates the performance state of the masters of the device's genpd and then updates the performance state of the genpd. The masters do the same and propagate performance state updates to their masters before updating their own. The performance state transition from genpd to its master is done with the help of dev_pm_opp_xlate_performance_state(), which looks at the OPP tables of both the domains to translate the state.

2018-12-14PM / Domains: Save OPP table pointer in genpdViresh Kumar
dev_pm_genpd_set_performance_state() will be required to call dev_pm_opp_xlate_performance_state() going forward to translate from performance state of a sub-domain to performance state of its master. And dev_pm_opp_xlate_performance_state() needs pointers to the OPP tables of both genpd and its master. Lets fetch and save them while the OPP tables are added. Fetching the OPP tables should never fail as we just added the OPP tables and so add a WARN_ON() for such a bug instead of full error paths.

2018-12-14OPP: Don't return 0 on error from of_get_required_opp_performance_state()Viresh Kumar
of_get_required_opp_performance_state() returns 0 on errors currently and a positive performance state otherwise. Since 0 is a valid performance state (representing off), it would be better if this routine returns negative values on error. That will also make it behave similar to dev_pm_opp_xlate_performance_state(), which also returns performance states and returns negative values on error. Change the return type of the function to "int" in order to return negative values. This doesn't have any users for now and so no other part of the kernel will be impacted with this change.

2018-12-14OPP: Add dev_pm_opp_xlate_performance_state() helperViresh Kumar
dev_pm_genpd_set_performance_state() needs to handle performance state propagation going forward. Currently this routine only gets the required performance state of the device's genpd as an argument, but it doesn't know how to translate that to master genpd(s) of the device's genpd. Introduce a new helper dev_pm_opp_xlate_performance_state() which will be used to translate from performance state of a device (or genpd sub-domain) to another device (or master genpd). Normally the src_table (of genpd sub-domain) will have the "required_opps" property set to point to one of the OPPs in the dst_table (of master genpd), but in some cases the genpd and its master have one to one mapping of performance states and so none of them have the "required-opps" property set. Return the performance state of the src_table as it is in such cases.

2018-12-14PM / Domains: Make genpd performance states orthogonal to the idlestatesUlf Hansson
It's quite questionable whether genpd internally should care about if the corresponding PM domain for a device is powered on, as to allow setting a new performance state for it. The assumptions creates an unnecessary limitation at this point, for both consumers and providers, but more importantly it also makes the code more complicated. Therefore, let's simplify the code to allow setting a performance state, by invoking the ->set_performance_state() callback, no matter whether the PM domain is powered on or off. Do note, this change means genpd providers needs to restore the performance state themselves during power on, via the ->power_on() callback. Moreover, they may also need to check that the PM domain is powered on, from their ->set_performance_state() callback, before deciding to update the state.

2018-12-13net: dev: Add extack argument to dev_set_mac_address()Petr Machata
A follow-up patch will add a notifier type NETDEV_PRE_CHANGEADDR, which allows vetoing of MAC address changes. One prominent path to that notification is through dev_set_mac_address(). Therefore give this function an extack argument, so that it can be packed together with the notification. Thus a textual reason for rejection (or a warning) can be communicated back to the user.
