2025-12-16drm: renesas: rz-du: mipi_dsi: Add support for RZ/V2H(P) SoCLad Prabhakar2-0/+482
Add MIPI DSI support for the Renesas RZ/V2H(P) SoC. Compared to the RZ/G2L family, the RZ/V2H(P) requires dedicated D-PHY PLL programming, different clock configuration, and additional timing parameter handling. The driver introduces lookup tables and helpers for D-PHY timings (TCLK*, THS*, TLPX, and ULPS exit) as specified in the RZ/V2H(P) hardware manual. ULPS exit timing depends on the LPCLK rate and is now handled explicitly. The implementation also adds support for 16 bpp RGB format, updates the clock setup path to use the RZ/V2H PLL divider limits, and provides new .dphy_init, .dphy_conf_clks, and .dphy_startup_late_init callbacks to match the RZ/V2H sequence. With these changes, the RZ/V2H(P) can operate the MIPI DSI interface in compliance with its hardware specification while retaining support for existing RZ/G2L platforms.

2025-12-16drm: renesas: rz-du: mipi_dsi: Add LPCLK clock supportLad Prabhakar1-0/+5
Add LPCLK clock handling to the RZ/G2L MIPI DSI driver to support proper DSI timing parameter configuration on RZ/V2H SoCs. While lpclk is present on both RZ/G2L and RZ/V2H SoCs, the RZ/V2H SoC specifically uses the lpclk rate to configure the DSI timing parameter ULPSEXIT. Introduce a new lpclk field in the rzg2l_mipi_dsi structure and acquire the "lpclk" clock during probe to enable lpclk rate-based timing calculations on RZ/V2H while maintaining compatibility with RZ/G2L.

2025-12-16dt-bindings: display: bridge: renesas,dsi: Document RZ/V2H(P) and RZ/V2NLad Prabhakar1-29/+91
Add the compatible string "renesas,r9a09g057-mipi-dsi" for the Renesas RZ/V2H(P) (R9A09G057) SoC. While the MIPI DSI LINK registers are shared with the RZ/G2L SoC, the D-PHY register layout differs. Additionally, the RZ/V2H(P) uses only two resets compared to three on RZ/G2L, and requires five clocks instead of six. To reflect these hardware differences, update the binding schema to support the reduced clock and reset requirements for RZ/V2H(P). Since the RZ/V2N (R9A09G056) SoC integrates an identical DSI IP to RZ/V2H(P), the same "renesas,r9a09g057-mipi-dsi" compatible string is reused for RZ/V2N.

aie_destroy_context() is invoked during error handling in aie2_create_context(). However, aie_destroy_context() assumes that the context's mailbox channel pointer is non-NULL. If mailbox channel creation fails, the pointer remains NULL and calling aie_destroy_context() can lead to a NULL pointer dereference. In aie2_create_context(), replace aie_destroy_context() with a function which request firmware to remove the context created previously.

2025-12-13i3c: adi: Fix confusing cleanup.h syntaxKrzysztof Kozlowski1-6/+4
Initializing automatic __free variables to NULL without need (e.g. branches with different allocations), followed by actual allocation is in contrary to explicit coding rules guiding cleanup.h: "Given that the "__free(...) = NULL" pattern for variables defined at the top of the function poses this potential interdependency problem the recommendation is to always define and assign variables in one statement and not group variable definitions at the top of the function when __free() is used." Code does not have a bug, but is less readable and uses discouraged coding practice, so fix that by moving declaration to the place of assignment.

2025-12-12accel/amdxdna: Fix race where send ring appears full due to delayed head updateLizhi Hou1-11/+16
The firmware sends a response and interrupts the driver before advancing the mailbox send ring head pointer. As a result, the driver may observe the response and attempt to send a new request before the firmware has updated the head pointer. In this window, the send ring still appears full, causing the driver to incorrectly fail the send operation. This race can be triggered more easily in a multithreaded environment, leading to unexpected and spurious "send ring full" failures. To address this, poll the send ring head pointer for up to 100us before returning a full-ring condition. This allows the firmware time to update the head pointer.
