2018-07-13drm: drop _mode_ from drm_mode_connector_attach_encoderDaniel Vetter
Again to align with the usual prefix of just drm_connector_. Again done with sed + manual fixup for indent issues.

2018-07-13drm: drop _mode_ from update_edit_property()Daniel Vetter
Just makes it longer, and for most things in drm_connector.[hc] we just use the drm_connector_ prefix. Done with sed + a bit of manual fixup for the indenting.

2018-05-23drm/i2c: tda998x: Remove VLA usageLaura Abbott
There's an ongoing effort to remove VLAs[1] from the kernel to eventually turn on -Wvla. The vla in reg_write_range is based on the length of data passed. The one use of a non-constant size for this range is bounded by the size buffer passed to hdmi_infoframe_pack which is a fixed size. Switch to this upper bound.

The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it. Fix this by using 'enum drm_mode_status' in the driver too.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

2017-11-07drm/drivers: drop redundant drm_edid_to_eld() callsJani Nikula
drm_add_edid_modes() now fills in the ELD automatically, so the calls to drm_edid_to_eld() are redundant. Remove them. All the other places are obvious, but nv50 has detached drm_edid_to_eld() from the drm_add_edid_modes() call.

It's dead code, the core handles all this directly now. The only special case is nouveau and tda988x which used one function for both legacy modeset code and -nv50 atomic world instead of 2 vtables. But amounts to exactly the same. v2: Rebase over the panel/brideg refactorings in stm/ltdc.

2017-07-14drm: handle HDMI 2.0 VICs in AVI info-framesShashank Sharma
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107). This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink. This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false. In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.

cec_read() is non-atomic in the presence of other I2C bus transactions to the same device. This presents a problem when we add support for the TDA9950 CEC engine part - both drivers can be trying to access the device. Avoid the inherent problems by switching to i2c_transfer() instead, which allows us to perform more than one bus transaction atomically. As this means we will be using I2C transactions rather than SMBUS, we have to check that the host supports I2C functionality.

A mode set is complex, and disables the ability to send infoframes to the sink, and is disruptive to audio - we have to mute the audio FIFO while doing a mode set.

As priv->audio_params can now be changed at run time, we need to be more careful about how we deal with a mode set. We must take the audio lock while checking if there's a valid audio configuration. However, it's slightly worse than that - during mode set, we mute the audio, and it must not be unmuted until we have finished the mode set. It is possible that the audio side may start while a mode set is in progress, so take the audio_mutex lock around the whole mode setting procedure.

2016-10-31drm/i2c: tda998x: mali-dp: hdlcd: refactor connector registrationBrian Starkey
Connectors shouldn't be registered until the rest of the whole device is set up, so that consistent state is presented to userspace. As such, remove the calls to drm_connector_register() and drm_connector_unregister() from tda998x, as these are now handled by drm_dev_(un)register() itself. To work with this change, the mali-dp and hdlcd bind and unbind sequences have to be reordered, to ensure that the componentised encoder/connector is bound before drm_dev_register() registers all connectors. Similarly, the device must be unregistered before the component is unbound. Altogether, this allows other drivers using tda998x to be de-midlayered, and to have less racy initialisation of their components. Splitting this commit into three (one per driver) isn't possible without intermediate breakage, so it is all squashed together here.

2016-01-13drm: Do not set connector->encoder in driversThierry Reding
An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.

2015-12-03drm/i2c: tda998x: unregister the connector in the unbind functionLiviu Dudau (ARM)
tda998x uses drm_connector_register() in the .bind function that needs to be balanced with a drm_connector_unregister() in the .unbind. Otherwise dangling sysfs entries are left behind and future rebinds will fail. Signed-off-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
