2024-01-03clk: mediatek: add pcw_chg_bit control for PLLs of MT7988Sam Shih
Introduce pcw_chg_bit member to struct mtk_pll_data and use it instead of the previously hardcoded PCW_CHG_MASK macro if set. This will needed for clocks on the MT7988 SoC.

2024-01-03clk: mediatek: mt8188-topckgen: Refactor parents for top_dp/edp muxesAngeloGioacchino Del Regno
The top_dp and top_edp muxes can be both parented to either TVDPLL1 or TVDPLL2, two identically specced PLLs for the specific purpose of giving out pixel clock: this becomes a problem when the MediaTek DisplayPort Interface (DPI) driver tries to set the pixel clock rate. In the usecase of two simultaneous outputs (using two controllers), it was seen that one of the displays would sometimes display garbled output (if any at all) and this was because: - top_edp was set to TVDPLL1, outputting X GHz - top_dp was set to TVDPLL2, outputting Y GHz - mtk_dpi calls clk_set_rate(top_edp, Z GHz) - top_dp is switched to TVDPLL1 - TVDPLL1 changes its rate, top_edp outputs the wrong rate. - eDP display is garbled To solve this issue, remove all TVDPLL1 parents from `top_dp` and all TVDPLL2 parents from `top_edp`, plus, necessarily switch both clocks to use the new MUX_GATE_CLR_SET_UPD_INDEXED() macro to be able to use the right bit index for the new parents list.

2024-01-03clk: mediatek: clk-mux: Support custom parent indices for muxesAngeloGioacchino Del Regno
Add support for customized parent indices for MediaTek muxes: this is necessary for the case in which we want to exclude some clocks from a mux's parent clocks list, where the exclusions are not from the very bottom of the list but either in the middle or the beginning. Example: - MUX1 (all parents) - parent1; idx=0 - parent2; idx=1 - parent3; idx=2 - MUX1 (wanted parents) - parent1; idx=0 - parent3; idx=2 To achieve that add a `parent_index` array pointer to struct mtk_mux, then in .set_parent(), .get_parent() callbacks check if this array was populated and eventually get the index from that. Also, to avoid updating all clock drivers for all SoCs, rename the "main" macro to __GATE_CLR_SET_UPD_FLAGS (so, `__` was added) and add the new member to it; furthermore, GATE_CLK_SET_UPD_FLAGS has been reintroduced as being fully compatible with the older version. The new parent_index can be specified with the new `_INDEXED` variants of the MUX_GATE_CLR_SET_UPD_xxxx macros.

2024-01-03i40e: Restore VF MSI-X state during PCI resetAndrii Staikov
During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability register will be cleared. This can lead to issues when a VF is assigned to a VM because in these cases the VF driver receives no indication of the PF PCI error/reset and additionally it is incapable of restoring the cleared flag in the hypervisor configuration space without fully reinitializing the driver interrupt functionality. Since the VF driver is unable to easily resolve this condition on its own, restore the VF MSI-X flag during the PF PCI reset handling.

Commit 3116f59c12bd ("i40e: fix use-after-free in i40e_sync_filters_subtask()") avoided use-after-free issues, by increasing refcount during update the VSI filter list to the HW. However, it missed the unicast situation. When deleting an unicast FDB entry, the i40e driver will release the mac_filter, and i40e_service_task will concurrently request firmware to add the mac_filter, which will lead to the following use-after-free issue.

This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5. Since, it causes a regression in which eDP displays with PSR support, but no Replay support (Sink support <= 0x03), fail to enable PSR and consequently all IGT amd_psr tests fail. So, revert this until a more suitable fix can be found. This got brought back accidently with the backmerge.

2024-01-03drm/amd/display: Verify disallow bits were cleared for idleNicholas Kazlauskas
[Why] A hang was observed where a read-modify-write access occurred due to the register for idle state being shared between DMCUB and driver. dmcub read - idle allow / no commit driver read - idle allow / no commit driver write - idle disallow / no commit dmcub write - idle allow / commit Resulting in DMCUB re-entering IPS after a disable and keeping the allow high. [How] Long term we need to split commit/allow into two registers or use shared DRAM state, but short term we can reduce the repro rate by ensuring that the disallow went through by bounding the expected worst case scenario.
