dt-bindings: coresight: qcom,coresight-tpdm: Fix too many 'reg'

2025-04-20T08:18:21Z

commit 1e4e454223f770748775f211455513c79cb3121e upstream. Binding listed variable number of IO addresses without defining them, however example DTS code, all in-tree DTS and Linux kernel driver mention only one address space, so drop the second to make binding precise and correctly describe the hardware.

dt-bindings: media: st,stmipid02: correct lane-polarities maxItems

2025-04-20T08:17:57Z

commit 3a544a39e0a4c492e3026dfbed018321d2bd6caa upstream. The MIPID02 can use up to 2 data lanes which leads to having a maximum item number of 3 for the lane-polarities since this also contains the clock lane.

ata: libata-core: Add 'external' to the libata.force kernel parameter

2025-04-20T08:17:41Z

[ Upstream commit deca423213cb33feda15e261e7b5b992077a6a08 ] Commit ae1f3db006b7 ("ata: ahci: do not enable LPM on external ports") changed so that LPM is not enabled on external ports (hotplug-capable or eSATA ports). This is because hotplug and LPM are mutually exclusive, see 7.3.1 Hot Plug Removal Detection and Power Management Interaction in AHCI 1.3.1. This does require that firmware has set the appropate bits (HPCP or ESP) in PxCMD (which is a per port register in the AHCI controller). If the firmware has failed to mark a port as hotplug-capable or eSATA in PxCMD, then there is currently not much a user can do. If LPM is enabled on the port, hotplug insertions and removals will not be detected on that port. In order to allow a user to fix up broken firmware, add 'external' to the libata.force kernel parameter. libata.force can be specified either on the kernel command line, or as a kernel module parameter. For more information, see Documentation/admin-guide/kernel-parameters.txt.

irqchip/gic-v3: Add Rockchip 3568002 erratum workaround

2025-04-20T08:17:35Z

[ Upstream commit 2d81e1bb625238d40a686ed909ff3e1abab7556a ] Rockchip RK3566/RK3568 GIC600 integration has DDR addressing limited to the first 32bit of physical address space. Rockchip assigned Erratum ID #3568002 for this issue. Add driver quirk for this Rockchip GIC Erratum. Note, that the 0x0201743b GIC600 ID is not Rockchip-specific and is common for many ARM GICv3 implementations. Hence, there is an extra of_machine_is_compatible() check.

coredump: Only sort VMAs when core_sort_vma sysctl is set
