2021-01-07regulator: mcp16502: lpm pin can be optional on some platformsClaudiu Beznea
On some platform (e.g. SAMA7G5) LPM pin should be optional as it can be controlled explicitly (via shutdown controller registers) in the platform specific power saving code to decrease the power consumption while suspended as this SoC pin may be connected to other devices that could take power saving actions based on its value.

2021-01-05Merge series "Add driver for dvfsrc, support for active state of scpsys" ↵Mark Brown
from Henry Chen <henryc.chen@mediatek.com>: This series is based on v5.10-rc1. The patchsets add support for MediaTek hardware module named DVFSRC (dynamic voltage and frequency scaling resource collector). The DVFSRC is a HW module which is used to collect all the requests from both software and hardware and turn into the decision of minimum operating voltage and minimum DRAM frequency to fulfill those requests. So, This series is to implement the dvfsrc driver to collect all the requests of operating voltage or DRAM bandwidth from other device drivers likes GPU/Camera through 3 frameworks basically: 1. interconnect framework: to aggregate the bandwidth requirements from different clients [1] https://patchwork.kernel.org/cover/10766329/ There has a hw module "DRAM scheduler", which used to control the throughput. The DVFSRC will collect forecast data of dram bandwidth from SW consumers(camera/gpu...), and according the forecast to change the DRAM frequency 2. Regualtor framework: to handle the operating voltage requirement from user or cosumer which not belong any power domain Changes in V6: * Remove the performace state support, because the request from consumer can be replaced by using interconnect and regulator framework. * Update the DT patches and convert them to DT schema. (Georgi) * Modify the comment format and coding style. (Mark) Changes in V5: * Support more platform mt6873/mt8192 * Drop the compatible and interconnect provider node and make the parent node an interconnect provider. (Rob/Georgi) * Make modification of interconnect driver from coding suggestion. (Georgi) * Move interconnect diagram into the commit text of patch. (Georgi) * Register the interconnect provider as a platform sub-device. (Georgi) Changes in V4: * Add acked TAG on dt-bindings patches. (Rob) * Declaration of emi_icc_aggregate since the prototype of aggregate function has changed meanwhile. (Georgi) * Used emi_icc_remove instead of icc_provider_del on probe. (Georgi) * Add dvfsrc regulator driver into series. * Bug fixed of mt8183_get_current_level. * Add mutex protection for pstate operation on dvfsrc_set_performance. Changes in V3: * Remove RFC from the subject prefix of the series * Combine dt-binding patch and move interconnect dt-binding document into dvfsrc. (Rob) * Remove unused header, add unit descirption to the bandwidth, rename compatible name on interconnect driver. (Georgi) * Fixed some coding style: check flow, naming, used readx_poll_timeout on dvfsrc driver. (Ryan) * Rename interconnect driver mt8183.c to mtk-emi.c * Rename interconnect header mtk,mt8183.h to mtk,emi.h * mtk-scpsys.c: Add opp table check first to avoid OF runtime parse failed Changes in RFC V2: * Remove the DT property dram_type. (Rob) * Used generic dts property 'opp-level' to get the performace state. (Stephen) * Remove unecessary dependency config on Kconfig. (Stephen) * Remove unused header file, fixed some coding style issue, typo, error handling on dvfsrc driver. (Nicolas/Stephen) * Remove irq handler on dvfsrc driver. (Stephen) * Remove init table on dvfsrc driver, combine hw init on trustzone. * Add interconnect support of mt8183 to aggregate the emi bandwidth.

2020-12-27proc mountinfo: make splice available againLinus Torvalds
Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.

The fix is to move Tegra's link up handling to .start_link() function like other DWC drivers. Tegra is a bit more complicated than others as it re-inits the whole DWC controller to retry the link. With this, the initialization ordering is restored to match the prior sequence.

2020-12-25genirq: Fix export of irq_to_desc() for powerpc KVMMichael Ellerman
Commit 64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()") removed the export of irq_to_desc() unless powerpc KVM is being built, because there is still a use of irq_to_desc() in modular code there. However it used: #ifdef CONFIG_KVM_BOOK3S_64_HV Which doesn't work when that symbol is =m, leading to a build failure: ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined! Fix it by checking for the definedness of the correct symbol which is CONFIG_KVM_BOOK3S_64_HV_MODULE.
