2023-10-30drm/i915: Flush WC GGTT only on required platformsNirmoy Das
gen8_ggtt_invalidate() is only needed for limited set of platforms where GGTT is mapped as WC. This was added as way to fix WC based GGTT in commit 0f9b91c754b7 ("drm/i915: flush system agent TLBs on SNB") and there are no reference in HW docs that forces us to use this on non-WC backed GGTT.

2023-10-29watchdog: wdat_wdt: Add timeout value as a param in ping methodXing Tong Wu
According to the WDAT spec that states about WATCHDOG_ACTION_SET_COUNTDOWN_PERIOD: "This action is required if WATCHDOG_ACTION_RESET does not explicitly write a new countdown value to a register during a reset." And that implies, WATCHDOG_ACTION_RESET may write a countdown value, thus may come with a WATCHDOG_INSTRUCTION_WRITE_COUNTDOWN, thus need the timeout value as parameter or would otherwise write 0. The watchdog for SIONCT6126 need a entry WATCHDOG_INSTRUCTION_WRITE_COUNTDOWN for WATCHDOG_ACTION_RESET action, I send this patch to support it.

2023-10-29sbsa_gwdt: Calculate timeout with 64-bit mathDarren Hart
Commit abd3ac7902fb ("watchdog: sbsa: Support architecture version 1") introduced new timer math for watchdog revision 1 with the 48 bit offset register. The gwdt->clk and timeout are u32, but the argument being calculated is u64. Without a cast, the compiler performs u32 operations, truncating intermediate steps, resulting in incorrect values. A watchdog revision 1 implementation with a gwdt->clk of 1GHz and a timeout of 600s writes 3647256576 to the one shot watchdog instead of 300000000000, resulting in the watchdog firing in 3.6s instead of 600s. Force u64 math by casting the first argument (gwdt->clk) as a u64. Make the order of operations explicit with parenthesis.

This patch adds watchdog support for the ITE IT8613 watchdog. IT8613 watchdog works in the same way as the other watchdogs supported by it87_wdt. Before this patch, IT8613 watchdog is not supported. After a modprobe, dmesg reports: it87_wdt: Unknown Chip found, Chip 8613 Revision 000c With this patch, modprobe it87_wdt recognizes the watchdog as the dmesg output shows: it87_wdt: Chip IT8613 revision 12 initialized. timeout=60 sec (nowayout=0 testmode=0) Watchdog tests on a LES v4 have been successful, the watchdog works as expected with this patch [1].
