In function dpu_encoder_phys_cmd_wait_for_commit_done we are always checking if the relative CTL is started by waiting for an interrupt to fire: it is fine to do that, but then sometimes we call this function while the CTL is up and has never been put down, but that interrupt gets raised only when the CTL gets a state change from 0 to 1 (disabled to enabled), so we're going to wait for something that will never happen on its own. Solving this while avoiding to restart the CTL is actually possible and can be done by just checking if it is already up and running when the wait_for_commit_done function is called: in this case, so, if the CTL was already running, we can say that the commit is done if the command transmission is complete (in other terms, if the interface has been flushed).

DPU driver contains code to parse clock items from device tree into special data struct and then enable/disable/set rate for the clocks using that data struct. However the DPU driver itself uses only parsing and enabling/disabling part (the rate setting is used by DP driver). Move this implementation to the DP driver (which actually uses rate setting) and replace hand-coded enable/disable/get loops in the DPU with the respective clk_bulk operations. Put operation is removed completely because, it is handled using devres instead. DP implementation is unchanged for now.

dpu_kms_debugfs_init() is invoked for each minor being registered. Most of the files created are unrelated to the minor, so there's no reason to present them per minor. The exception to this is the DisplayPort code, which ends up invoking dp_debug_get() for each minor, each time associate the allocated object with dp->debug. As such dp_debug will create debugfs files in both the PRIMARY and the RENDER minor's debugfs directory, but only the last reference will be remembered. The only use of this reference today is in the cleanup path in dp_display_deinit_sub_modules() and the dp_debug_private object does outlive the debugfs entries in either case, so there doesn't seem to be any adverse effects of this, but per the code the current behavior is unexpected, so change it to only create debugfs files for the PRIMARY minor.

Add SC8180x to the hardware catalog, for initial support for the platform. Due to limitations in the DP driver only one of the four DP interfaces is left enabled. The SC8180x platform supports the newly added DPU_INTF_WIDEBUS flag and the Windows-on-Snapdragon bootloader leaves the widebus bit set, so this is flagged appropriately to ensure widebus is disabled - for now.

Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If the value is NULL, then the function will return 0 instead of a proper return code. Moreover none of dpu_hw_*_init() functions can return NULL. So, replace all dpu_rm_init()'s IS_ERR_OR_NULL() calls with IS_ERR(). Signed-off-by:

Now as dpu_hw_intf is not hanled by dpu_rm_get_assigned_resources, there is no point in embedding the (empty) struct dpu_hw_blk into dpu_hw_intf (and using typecasts between dpu_hw_blk and dpu_hw_intf). Drop it and use dpu_hw_intf directly. Signed-off-by:

commit 6f1b2285 introduces a regression which can deadlock as follows: Task1: Task2: jbd2_journal_commit_transaction ocfs2_test_bg_bit_allocatable spin_lock(&jh->b_state_lock) jbd_lock_bh_journal_head __jbd2_journal_remove_checkpoint spin_lock(&jh->b_state_lock) jbd2_journal_put_journal_head jbd_lock_bh_journal_head Task1 and Task2 lock bh->b_state and jh->b_state_lock in different order, which finally result in a deadlock.

Patch series "ocfs2: fix a deadlock case". This fixes a deadlock case in ocfs2. We firstly export jbd2 symbols jbd2_journal_[grab|put]_journal_head as preparation and later use them in ocfs2 insread of jbd_[lock|unlock]_bh_journal_head to fix the deadlock. This patch (of 2): This exports symbols jbd2_journal_[grab|put]_journal_head, which will be used outside modules, e.g. ocfs2.
