Thank you!
The following changes since commit 4cece764965020c22cff7665b18a012006359095: Linux 6.9-rc1 (2024-03-24 14:10:05 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git tags/clk-fixes-for-linus for you to fetch changes up to d3e8a91a848a5941e3c31ecebd6b2612b37e01a6: clk: mediatek: mt7988-infracfg: fix clocks for 2nd PCIe port (2024-04-10 20:50:26 -0700) ---------------------------------------------------------------- A couple clk driver fixes, a build fix, and a deadlock fix. - Mediatek mt7988 has broken PCIe because the wrong parent is used - Mediatek clk drivers may deadlock when registering their clks because the clk provider device is repeatedly runtime PM resumed and suspended during probe and clk registration. Resuming the clk provider device deadlocks with an ABBA deadlock due to genpd_lock and the clk prepare_lock. The fix is to keep the device runtime resumed while registering clks. - Another runtime PM related deadlock, this time with disabling unused clks during late init. We get an ABBA deadlock where a device is runtime PM resuming (or suspending) while the disabling of unused clks is happening in parallel. That runtime PM action calls into the clk framework and tries to grab the clk prepare_lock while the disabling of unused clks holds the prepare_lock and is waiting for that runtime PM action to complete. The fix is to runtime resume all the clk provider devices before grabbing the clk prepare_lock during disable unused. - A build fix to provide an empty devm_clk_rate_exclusive_get() function when CONFIG_COMMON_CLK=n ---------------------------------------------------------------- Daniel Golle (1): clk: mediatek: mt7988-infracfg: fix clocks for 2nd PCIe port Pin-yen Lin (1): clk: mediatek: Do a runtime PM get on controllers during probe Stephen Boyd (6): clk: Remove prepare_lock hold assertion in __clk_release() clk: Don't hold prepare_lock when calling kref_put() clk: Initialize struct clk_core kref earlier clk: Get runtime PM before walking tree during disable_unused clk: Get runtime PM before walking tree for clk_summary Merge branch 'clk-rpm' into clk-fixes Uwe Kleine-König (1): clk: Provide !COMMON_CLK dummy for devm_clk_rate_exclusive_get() drivers/clk/clk.c | 173 ++++++++++++++++++++++------- drivers/clk/mediatek/clk-mt7988-infracfg.c | 2 +- drivers/clk/mediatek/clk-mtk.c | 15 +++ include/linux/clk.h | 5 + 4 files changed, 156 insertions(+), 39 deletions(-)
