2024-06-14drm/i915/gvt: rename range variable to strideJani Nikula
Range is a bit odd name for what really is stride. Rename. Switch to u32 while at it.

2024-06-14drm/i915/gvt: use proper i915_reg_t for calc_index() parametersJani Nikula
In order to be able to use the proper register macros instead of the underscore prefixed ones, pass i915_reg_t for the calc_index() parameters. Side note: DSPSURF is really about planes, not pipes. Fixed stride doesn't work for plane C for CHV (but that's okay for gvt). This doesn't support planes beyond C either. But all that is unrelated to the change at hand.

2024-06-14accel/ivpu: Implement DCT handlingJacek Lawrynowicz
When host system is under heavy load and the NPU is already running on the lowest frequency, PUNIT may request Duty Cycle Throttling (DCT). This will further reduce NPU power usage. PUNIT requests DCT mode using Survabilty IRQ and mailbox register. The driver then issues a JSM message to the FW that enables the DCT mode. If the NPU resets while in DCT mode, the driver request DCT mode during FW boot. Also add debugfs "dct" file that allows to set arbitrary DCT percentage, which is used by driver tests.

2024-06-14arm/komeda: Remove all CONFIG_DEBUG_FS conditional compilationspengfuyuan
Since the debugfs functions have no-op stubs for CONFIG_DEBUG_FS=n, the compiler will optimize the rest away since they are no longer referenced. The benefit of removing the conditional compilation is that the build is actually tested for both CONFIG_DEBUG_FS configuration values. Assuming most developers have it enabled, CONFIG_DEBUG_FS=n is not tested much and may fail the build due to the conditional compilation.

2024-06-13net: dsa: lantiq_gswip: Consistently use macros for the mac bridge tableMartin Blumenstingl
Only bits [5:0] in mac_bridge.key[3] are reserved for the FID. Also, for dynamic (learned) entries, bits [7:4] in mac_bridge.val[0] represents the port. Introduce new macros GSWIP_TABLE_MAC_BRIDGE_KEY3_FID and GSWIP_TABLE_MAC_BRIDGE_VAL0_PORT macro and use it throughout the driver. Also rename and update GSWIP_TABLE_MAC_BRIDGE_VAL1_STATIC to use the BIT() macro. This makes the driver code easier to understand.

2024-06-13net: dsa: lantiq_gswip: do also enable or disable cpu portMartin Schiller
Before commit 74be4babe72f ("net: dsa: do not enable or disable non user ports"), gswip_port_enable/disable() were also executed for the cpu port in gswip_setup() which disabled the cpu port during initialization. Let's restore this by removing the dsa_is_user_port checks. Also, let's clean up the gswip_port_enable() function so that we only have to check for the cpu port once. The operation reordering done here is safe.
