The Samsung ATNA33XC20 panel is an AMOLED eDP panel that has backlight control over the DP AUX channel. This panel is _almost_ able to be controlled in a "simple" way (and it originally was implemented in panel-simple.c), but it's really impossible to get the backlight semantics right there without adding wacky special-case code to panel-simple. Let's give up and clone the parts of panel-simple that we need and implement the power sequence that this panel needs. NOTE: we'll still leave the devicetree bindings alone. Even though the power-sequencing is non-standard the bindings are still "simple". Signed-off-by:

This reverts commit 18a1488b. Those delays were added to support the Samsung ATNA33XC20 panel. However, we've moving that to its own panel driver and out of panel-simple. That means we don't need the ability to specify this delay. NOTE: it's unlikely we want to keep this delay "just in case" some other panel needs it. The enable-gpio and the power supply are really supposed to be different ways to specify the same thing: the main enable of the panel. Supporting a delay between them doesn't really make sense.

This reverts commit 4bfe6c8f. This panel's power sequencing really can't be handled properly by panel-simple because of the special sequencing needed for the EL_ON3 GPIO. The only way it was sorta working in the past was by trying to jam that signal into the "enable-gpio", but that really wasn't a good fit. We'll add a custom panel driver for this panel to do it right. Signed-off-by:

The manual has always said that we need 100 us delays in a few places. Though it hasn't seemed to be a big deal to skip these, let's add them in case it makes something happier. NOTE: this fixes no known issues but it seems good to make it right. Fixes: a095f15c ("drm/bridge: add support for sn65dsi86 bridge driver") Signed-off-by:

When testing with a panel that's apparently a little more persnickety about the correct power sequence (specifically Samsung ATNA33XC20), we found that the ti-sn65dsi86 was doing things just slightly wrong. Looking closely at the ti-sn65dsi86's datasheet, the power off sequence is supposed to be: 1. Clear VSTREAM_ENABLE bit 2. Stop DSI stream from GPU. DSI lanes must be placed in LP11 state. 3. Program the ML_TX_MODE to 0x0 (OFF) 4. Program the DP_NUM_LANES register to 0x0 5. Clear the DP_PLL_EN bit. 6. Deassert the EN pin. 7. Remove power from supply pins Since we were doing the whole sequence in the "disable", I believe that step #2 (stopping the DSI stream from the GPU) wasn't happening. We also weren't setting DP_NUM_LANES to 0. Let's fix this. NOTE: things are a little asymmetric now. For instance, we turn the PLL on in "enable" but now we're not turning it off until "post_disable". It would seem to make sense to move the PLL turning on to "pre_enable" to match. Unfortunately, I don't believe that's allowed. It looks as if (in the non-refclk mode which probably nobody is using) we have to wait until the MIPI clock is there before we can enable the PLL. In any case, the way it is here won't really hurt--it'll just leave the PLL on a little longer. Fixes: a095f15c ("drm/bridge: add support for sn65dsi86 bridge driver") Signed-off-by:

The function drm_edp_backlight_init() is defined such that the "driver_pwm_freq_hz" parameter is optional--it's 0 if you don't want to futz with it. If you follow this variable through, you'll find out that if it's 0 we won't ever set the "bl->pwmgen_bit_count", leaving it as 0. That means that before using it in drm_edp_backlight_enable() we need to check to see if it's non-zero. Programming this field to zero was confusing the panel I tested with (Samsung ATNA33XC20). The backlight still worked somewhat but the brightness values didn't correspond to what they should have been.

The kerneldoc in drm_lease.c is unused because none of the functions are driver interfaces as the symbols are not exported. Since they aren't used and much of the existing comments don't provide any insights (e.g. they just repeat the function name or list out the function parameters), they should be removed to make them easier to maintain and to make useful info more obvious. As a note, many of the comments mention whether idr_mutex should be held, but these are mostly redundant in cases where the function contains lockdep assertions or grabs the mutex. To simplify review, here's the reasoning behind each update. drm_lease_owner: function name is self-descriptive _drm_find_lessee: function name is self-descriptive _drm_lease_held_master: function name and signature are self-descriptive _drm_has_leased: kerneldoc is summarized into a comment because the function name could be interpreted ambiguously (check if the object has been leased VS check if the master has a lease on the object) _drm_lease_held: Retain the idr_mutex comment because the function does not directly grab the mutex or use a lockdep assertion. Otherwise, the function name is self-descriptive. drm_lease_held: function name is self-descriptive drm_lease_filter_crtcs: Kerneldoc is summarized into a comment because the function name could be interpreted ambiguously (filter leases based on crtcs mask VS filter crtcs mask based on leases) drm_lease_create: Kerneldoc removed. Useful function details such as atomic leasing are retained. Errno interpretations are useful and retained. drm_lease_destroy: function name is self-descriptive. Additional information is also removed as they're already present as comments inside the function. _drm_lease_revoke: function name is self-descriptive drm_lease_revoke: function name is self-descriptive drm_mode_create_lease_ioctl: Kerneldoc removed, but useful function details retained. drm_mode_list_lessees_ioctl: function name is self-descriptive. Additional details restate what the code does. drm_mode_get_lease_ioctl: Function summary retained to clarify that it's the leased objects that are returned, not the lease structure. drm_mode_revoke_lease_ioctl: Kerneldoc removed, but useful function details retained.

An early pull for v5.15 (there'll be more coming in a week or two), consisting of the drm/scheduler conversion and a couple other small series that one was based one. Mostly sending this now because IIUC danvet wanted it in drm-next so he could rebase on it. (Daniel, if you disagree then speak up, and I'll instead include this in the main pull request once that is ready.)

It turns out that these variables are also passed through the hdmi codec parameters structure. Convert all the users to use this structure, and if it's used multiple times use a variable to store it instead of dereferencing it every time. Reviewed-by:

We make the following changes to the documentation of drm leases to make it easier to reason about their usage. In particular, we clarify the lifetime and locking rules of lease fields in drm_master: 1. Make it clear that &drm_device.mode_config.idr_mutex protects the lease idr and list structures for drm_master. The lessor field itself doesn't need to be protected as it doesn't change after it's set in drm_lease_create. 2. Add descriptions for the lifetime of lessors and leases. 3. Add an overview DOC: section in drm-uapi.rst that defines the terminology for drm leasing, and explains how leases work and why they're used. Signed-off-by:
