DisplayPort supports EDID up to 256 bytes (blocks 0 and 1). Update the block check to allow these two blocks. For any block beyond that (i.e. the monitor's EDID is larger than the 256 bytes ASPEED DP can hold), report it as an all-zero block instead of a read failure. Also remove the manual checksum/extension-count patch of block 0's last four bytes. That code was already dead, so the condition can never be true.

2026-08-31usb: typec: ucsi: displayport: Fix OOB altmode array indexJameson Thies
The UCSI displayport driver indexes the connector's port altmode array with the GET_CURRENT_CAM response after checking it is not 0xff. The port altmode array is UCSI_MAX_ALTMODES elements long. If the PPM returns an invalid GET_CURRENT_CAM response above UCSI_MAX_ALTMODES and not equal to 0xff, the kernel may crash with an array index OOB error. Update the UCSI displayport driver to verify the current cam is less than UCSI_MAX_ALTMODES before accessing the port altmode array.

2026-08-31thunderbolt: dma_test: Tear down DMA paths before stopping the ringsHaotian Zhang
dma_test_stop_rings() stops the RX and TX rings before calling tb_xdomain_disable_paths(). tb_ring_stop() zeroes the ring's descriptor base and the cancellation callbacks unmap and free the frame buffers, so by the time __tb_path_deactivate_hop() polls the hop's 'pending' bit any data still in flight has nowhere to drain to; on ASMedia ASM4242-class host routers the bit never clears and every teardown burns the full 500 ms timeout. This is the same defect as the one in tbnet_tear_down(), fixed as CVE-2026-74691 ("net: thunderbolt: Tear down DMA paths before stopping the rings"). Move the tb_xdomain_disable_paths() call before the tb_ring_stop() calls in dma_test_stop_rings(), so in-flight data drains while the rings are still active, and only then stop the rings and free the frame buffers.

2026-08-31pinctrl: renesas: rzg2l: Add SD channel POC support for RZ/G3LBiju Das
Add power-on control (POC) support for SD channels 1 and 2 on the RZ/G3L SoC (r9a08g046). Introduce PIN_CFG_IO_VMC_SD2 capability flag (bit 22) and SD_CH2_POC register offset (0x3024). Extend rzg2l_caps_to_pwr_reg() to return SD_CH2_POC when PIN_CFG_IO_VMC_SD2 is set. Replace RZG3L_MPXED_PIN_FUNCS() with RZG2L_MPXED_COMMON_PIN_FUNCS() for port PG and PH pins, dropping PIN_CFG_SOFT_PS which is inappropriate for SD pins, and annotate them with PIN_CFG_IO_VMC_SD1 and PIN_CFG_IO_VMC_SD2 respectively. Annotate all RZ/G3L SD0 dedicated pins (CLK, CMD, RST#, DS, DAT0–DAT7) with PIN_CFG_IO_VMC_SD0 so that power-source register lookups work correctly for those pins. Add sd_ch2 field to rzg2l_register_offsets and rzg2l_pinctrl_reg_cache to save and restore the SD_CH2_POC register across suspend/resume cycles.

Add a new fractional PLL clock type (CLK_TYPE_G3L_PLLDSI) for the RZ/G3L SoC's PLL7, which drives the DSI interface and requires a dedicated parameter calculation and programming sequence distinct from other PLLs in the RZ/G2L family. PLL7 output frequency is determined by the formula: Ffdco = (NIR + NFR / 4096) * (Fosc / MR) Ffout = Ffdco / (1 << PR) where: - Fosc = 24 MHz (oscillator input) - PR in [0, 4] (post divider, power-of-two) - MR in [1, 12] (input pre-divider) - NIR in [56, 375], NFR in [0, 4095] (integer and fractional parts) The FDCO must fall within one of two valid ranges: 900–2000 MHz (rangesel=0) or 2000–3000 MHz (rangesel=1). The parameter search in rzg3l_dsi_get_pll_parameters_values() iterates over all valid (MR, PR) combinations, filtering by the required FPFD range of 8–16 MHz, then delegates to rzg3l_dsi_compute_pll_parameters() to find the NIR/NFR pair that best approximates the requested rate. An exact match returns immediately; otherwise the combination with the smallest absolute frequency error is used. Computed parameters are cached in pll7_dsi_params within pll_clk to avoid redundant recalculation in determine_rate() when the requested rate has not changed.

2026-08-31clk: renesas: rzg2l: Add DSI divider clock support for RZ/G3LBiju Das
Add a new DSI divider clock type (CLK_TYPE_G3L_PLLDSI_DIV) for the RZ/G3L SoC, which requires a different divider implementation than the existing RZ/G2L DSI divider clock. The RZ/G3L DSI divider uses two cascaded dividers, DIV_DSI_A and DIV_DSI_B, where the effective divider is: rate = parent_rate / ((1 << div_a) * (div_b + 1)) DIV_DSI_A is a power-of-two divider with values in the range [0, 5], and DIV_DSI_B is a linear divider with values in the range [1, 16]. Introduce the g3l_dsi_div_hw_data structure, rzg3l_cpg_dsi_div_ops, and rzg3l_cpg_dsi_div_clk_register() to implement the new clock type, and add the DEF_G3L_PLLDSI_DIV() macro for use in clock table definitions.

2026-08-31clk: renesas: Clean-up simple provider misuse of the consumer APIJerome Brunet
Clock provider should not be using the consumer interface. In other words, a provider should not be dealing with struct clk. This change targets occurrences for which the provider uses the consumer interface and corresponding clk_hw interface exist.

2026-08-31soc: renesas: rcar-mfis: Convert spinlock to raw_spinlockWolfram Sang
With the upcoming hwspinlock support for this driver, mfis_write() can also be accessed from atomic contexts. Convert the spinlock guarding the unprotect register to a raw_spinlock, so we will avoid potential deadlocks with preempt_rt.

People not very familiar with Renesas R-Car SoCs may not know the meaning of the MFIS acronym. Hence expand it in the help text. While at it, drop "core driver", as there is only a single driver, unlike early development revisions, and replace "Gen5" by "R-Car Gen5".

2026-08-31cpuidle: psci: Fix support for probe deferral by dropping the faux deviceUlf Hansson
At the conversion to the faux driver/device we broke the support for probe deferral. In hindsight, the move to the faux device seems questionable, as it simply makes the code more complicated and for no good reason. To fix the support for the probe deferral let's therefore restore the old code and drop the faux device.

pci_match_device() can return the dummy pci_device_id_any entry when a device is force-bound via sysfs driver_override, in which case ->driver_data is unset (NULL). i915_pci_probe() casts it to struct intel_device_info * unconditionally and dereferences intel_info->require_force_probe, causing a NULL-ptr-deref.

2026-08-31drm/i915/display: Clear SEL_FETCH_PLANE_CTL on plane disableNemesa Garg
icl_plane_disable_sel_fetch_arm() wrote SEL_FETCH_PLANE_CTL = 0 only when crtc_state->enable_psr2_sel_fetch was set. If a plane was disabled after selective fetch had been turned off, the guard fired early and left the register's enable bit set in hardware. The bit is harmless until selective fetch is re-enabled. When it is, the hardware resumes fetching for the now-disabled plane and keeps its old DDB range reserved. i9xx_cursor_disable_sel_fetch_arm() has the same guard on SEL_FETCH_CUR_CTL and is fixed the same way. v2: Add same check for cursor also.
