2025-11-14s390/mm: Fix __ptep_rdp() inline assemblyHeiko Carstens
When a zero ASCE is passed to the __ptep_rdp() inline assembly, the generated instruction should have the R3 field of the instruction set to zero. However the inline assembly is written incorrectly: for such cases a zero is loaded into a register allocated by the compiler and this register is then used by the instruction. This means that selected TLB entries may not be flushed since the specified ASCE does not match the one which was used when the selected TLB entries were created. Fix this by removing the asce and opt parameters of __ptep_rdp(), since all callers always pass zero, and use a hard-coded register zero for the R3 field.

2025-11-14arm64: dts: qcom: qrb2210-rb1: Fix UART3 wakeup IRQ stormPraveen Talari
For BT use cases, pins are configured with pull-up state in sleep state to avoid noise. If IRQ type is configured as level high and the GPIO line is also in a high state, it causes continuous interrupt assertions leading to an IRQ storm when wakeup irq enables at system suspend/runtime suspend. Switching to edge-triggered interrupt (IRQ_TYPE_EDGE_FALLING) resolves this by only triggering on state transitions (high-to-low) rather than maintaining sensitivity to the static level state, effectively preventing the continuous interrupt condition and eliminating the wakeup IRQ storm.

Add a new code file to the mali-c55 driver that registers an output video node for userspace to queue buffers of parameters to. Handlers are included to program the statistics generation plus the white balance, black level correction and mesh shading correction blocks.

2025-11-14media: platform: Add mali-c55 3a stats devnodeDaniel Scally
Add a new code file to govern the 3a statistics capture node. On ISP_START, fill the stats buffer by reading out the metering space in the ISP's memory. This is done for the non-active config just as the dma transfer of the registers is. To acheive that, move the checking of the current config outside of mali_c55_swap_next_config() so we can use it for both functions.
