2022-02-25arm64: Change elfcore for_each_mte_vma() to use VMA iteratorLiam Howlett1-6/+17
Rework for_each_mte_vma() to use a VMA iterator instead of an explicit linked-list. This will allow easy integration with the maple tree work which removes the VMA list altogether.

2022-02-25memory: Update of_memory lpddr2 revision-id bindingJulius Werner1-6/+13
This patch updates the code parsing the "jedec,lpddr2" device tree binding to use the new `revision-id` property instead of the deprecated `revision-id1` and `revision-id2` properties if available.

2022-02-25dt-bindings: memory: lpddr2: Adjust revision ID property to match lpddr3Julius Werner1-2/+15
Commit 3539a2c6c689 ("dt-bindings: memory: lpddr2: Add revision-id properties") added the properties `revision-id1` and `revision-id2` to the "jedec,lpddr2" binding. The "jedec,lpddr3" binding already had a single array property `revision-id` for the same purpose. For consistency between related memory types, this patch deprecates the LPDDR2 properties and instead adds a property in the same style as for LPDDR3 to that binding.

The features can be enabled or disabled from the firmware as well as the features can be configured at runtime by querying IOCTL_SET_FEATURE_CONFIG id. Similarly, the user can get the configured values of features by querying IOCTL_GET_FEATURE_CONFIG id.

2022-02-25misc: rtsx: conditionally build rtsx_pm_power_saving()Tom Rix1-32/+32
On s390 allyesconfig, there is this build error rtsx_pcr.c:1084:13: error: 'rtsx_pm_power_saving' defined but not used 1084 | static void rtsx_pm_power_saving(struct rtsx_pcr *pcr) | ^~~~~~~~~~~~~~~~~~~~ rtsx_pm_power_saving() is only used by rtsx_pci_runtime_idle() which is conditional on CONFIG_PM. So conditionally build rtsx_pm_power_saving() and the similar rtsx_comm_pm_power_saving() and rtsx_enable_aspm().

2022-02-25config: android-recommended: Don't explicitly disable CONFIG_AIOMarijn Suijten1-1/+0
Android nowadays (for a couple years already) requires AIO for at least its `adb` "Android Debug Bridge" [1]. Without this config option (`default y`) it simply refuses start, making users unable to connect to their phone for debugging purposes when using these kernel fragments.
