2021-07-31drm/panel: atna33xc20: Introduce the Samsung ATNA33XC20 panelDouglas Anderson3-0/+378
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".

2021-07-31Revert "drm/panel-simple: Support for delays between GPIO & regulator"Douglas Anderson1-28/+0
This reverts commit 18a1488bf1e13fc3fc96d7948466b2166067c6c8. 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 4bfe6c8f7c23b01719671b69fd29b87a35ccd9d6. 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.

2021-07-31drm/bridge: ti-sn65dsi86: Fix power off sequenceDouglas Anderson1-4/+7
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.

2021-07-31drm/dp: Don't zero PWMGEN_BIT_COUNT when driver_pwm_freq_hz not specifiedDouglas Anderson1-4/+6
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.

2021-07-30drm: clean up unused kerneldoc in drm_lease.cDesmond Cheong Zhi Xi1-123/+8
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.

This converts the internal backlight in the Sony ACX424AKP driver to do it the canonical way: - Assign the panel->backlight during probe. - Let the panel framework handle the backlight. - Make the backlight .set_brightness() turn the backlight off completely if blank. - Fix some dev_err_probe() use cases along the way. Tested on the U8500 HREF520 reference design.

Inside drm_is_current_master, using the outer drm_device.master_mutex to protect reads of drm_file.master makes the function prone to creating lock hierarchy inversions. Instead, we can use the drm_file.master_lookup_lock that sits at the bottom of the lock hierarchy.

2021-07-28drm/amdgpu/display: only enable aux backlight control for OLED panelsAlex Deucher1-2/+2
We've gotten a number of reports about backlight control not working on panels which indicate that they use aux backlight control. A recent patch: commit 2d73eabe2984a435737498ab39bb1500a9ffe9a9 Author: Camille Cho <Camille.Cho@amd.com> Date: Thu Jul 8 18:28:37 2021 +0800 drm/amd/display: Only set default brightness for OLED [Why] We used to unconditionally set backlight path as AUX for panels capable of backlight adjustment via DPCD in set default brightness. [How] This should be limited to OLED panel only since we control backlight via PWM path for SDR mode in LCD HDR panel.

The commit message seems to indicate that PWM should be used for SDR mode on HDR panels. Do something similar for backlight control in general.
