2020-04-25drm/bridge: panel: Return always an error pointer in drm_panel_bridge_add()Enric Balletbo i Serra1-3/+3
Since commit 89958b7cd955 ("drm/bridge: panel: Infer connector type from panel by default"), drm_panel_bridge_add() and their variants can return NULL and an error pointer. This is fine but none of the actual users of the API are checking for the NULL value. Instead of change all the users, seems reasonable to return an error pointer instead. So change the returned value for those functions when the connector type is unknown.

2020-04-23Revert "drm/dp_mst: Remove single tx msg restriction."Lyude Paul2-2/+17
This reverts commit 6bb0942e8f46863a745489cce27efe5be2a3885e. Unfortunately it would appear that the rumors we've heard of sideband message interleaving not being very well supported are true. On the Lenovo ThinkPad Thunderbolt 3 dock that I have, interleaved messages appear to just get dropped: [drm:drm_dp_mst_wait_tx_reply [drm_kms_helper]] timedout msg send 00000000571ddfd0 2 1 [dp_mst] txmsg cur_offset=2 cur_len=2 seqno=1 state=SENT path_msg=1 dst=00 [dp_mst] type=ENUM_PATH_RESOURCES contents: [dp_mst] port=2 DP descriptor for this hub: OUI 90-cc-24 dev-ID SYNA3 HW-rev 1.0 SW-rev 3.12 quirks 0x0008 It would seem like as well that this is a somewhat well known issue in the field. From section 5.4.2 of the DisplayPort 2.0 specification: There are MST Sink/Branch devices in the field that do not handle interleaved message transactions. To facilitate message transaction handling by downstream devices, an MST Source device shall generate message transactions in an atomic manner (i.e., the MST Source device shall not concurrently interleave multiple message transactions). Therefore, an MST Source device shall clear the Message_Sequence_No value in the Sideband_MSG_Header to 0. MST Source devices that support field policy updates by way of software should update the policy to forego the generation of interleaved message transactions. This is a bit disappointing, as features like HDCP require that we send a sideband request every ~2 seconds for each active stream. However, there isn't really anything in the specification that allows us to accurately probe for interleaved messages. If it ends up being that we -really- need this in the future, we might be able to whitelist hubs where interleaving is known to work-or maybe try some sort of heuristics. But for now, let's just play it safe and not use it. Signed-off-by: Lyude Paul <[email protected]> Fixes: 6bb0942e8f46 ("drm/dp_mst: Remove single tx msg restriction.")

2020-04-20drm/ast: Allocate initial CRTC state of the correct sizeThomas Zimmermann1-1/+12
The ast driver inherits from DRM's CRTC state, but still uses the atomic helper for struct drm_crtc_funcs.reset, drm_atomic_helper_crtc_reset(). The helper only allocates enough memory for the core CRTC state. That results in an out-ouf-bounds access when duplicating the initial CRTC state.

2020-04-17video: fbdev: imxfb: ensure balanced regulator usageUwe Kleine-König1-6/+21
The fbdev framework doesn't care to call the .set_power callback only on changes. So the driver has to care for itself that the regulator doesn't get disabled more often than enabled. This fixes the regulator warning unbalanced disables for lcd supply which can be triggered by doing echo 4 > /sys/class/lcd/imxfb-lcd/lcd_power twice.

2020-04-17video: fbdev: controlfb: remove obsolete module supportBartlomiej Zolnierkiewicz1-24/+1
CONFIG_FB_CONTROL is bool, hence the Apple "control" frame buffer driver cannot be built as a module. Replace module_init() by device_initcall().

2020-04-17video: fbdev: controlfb: add COMPILE_TEST supportBartlomiej Zolnierkiewicz2-14/+29
Add COMPILE_TEST support to controlfb driver for better compile testing coverage. While at it: - convert driver to use eieio() and dcbf() helpers instead of open-coding them - add invalid_vram_cache() helper to avoid code duplication Acked-by: Sam Ravnborg <[email protected]> Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Use in_le32() instead of le32_to_cpup() to fix sparse warning about improper type of the argument. Also drop inline keyword from control_par_to_var() prototype (to match function definition).

2020-04-17video: ssd1307fb: Convert to atomic PWM APIAndy Shevchenko1-12/+5
Use the atomic API wherever appropriate and get rid of pwm_apply_args() call (the reference period and polarity are now explicitly set when calling pwm_apply_state()). We also make use of the pwm_set_relative_duty_cycle() helper to ease relative to absolute duty_cycle conversion.
