drm: Add helper for DP++ adaptors

2016-05-23T08:10:46Z

Add a helper which aids in the identification of DP dual mode (aka. DP++) adaptors. There are several types of adaptors specified: type 1 DVI, type 1 HDMI, type 2 DVI, type 2 HDMI Type 1 adaptors have a max TMDS clock limit of 165MHz, type 2 adaptors may go as high as 300MHz and they provide a register informing the source device what the actual limit is. Supposedly also type 1 adaptors may optionally implement this register. This TMDS clock limit is the main reason why we need to identify these adaptors. Type 1 adaptors provide access to their internal registers and the sink DDC bus through I2C. Type 2 adaptors provide this access both via I2C and I2C-over-AUX. A type 2 source device may choose to implement either of these methods. If a source device implements the I2C-over-AUX method, then the driver will obviously need specific support for such adaptors since the port is driven like an HDMI port, but DDC communication happes over the AUX channel. This helper should be enough to identify the adaptor type (some type 1 DVI adaptors may be a slight exception) and the maximum TMDS clock limit. Another feature that may be available is control over the TMDS output buffers on the adaptor, possibly allowing for some power saving when the TMDS link is down. Other user controllable features that may be available in the adaptors are downstream i2c bus speed control when using i2c-over-aux, and some control over the CEC pin. I chose not to provide any helper functions for those since I have no use for them in i915 at this time. The rest of the registers in the adaptor are mostly just information, eg. IEEE OUI, hardware and firmware revision, etc. v2: Pass adaptor type to helper functions to ease driver implementation Fix a bunch of typoes (Paulo) Add DRM_DP_DUAL_MODE_UNKNOWN for the case where we don't (yet) know the type (Paulo) Reject 0x00 and 0xff DP_DUAL_MODE_MAX_TMDS_CLOCK values (Paulo) Adjust drm_dp_dual_mode_detect() type2 vs. type1 detection to ease future LSPCON enabling Remove the unused DP_DUAL_MODE_LAST_RESERVED define v3: Fix kernel doc function argument descriptions (Jani) s/NONE/UNKNOWN/ in drm_dp_dual_mode_detect() docs Add kernel doc for enum drm_dp_dual_mode_type Actually build the docs Fix more typoes v4: Adjust code indentation of type2 adaptor detection (Shashank) Add debug messages for failurs cases (Shashank) v5: EXPORT_SYMBOL(drm_dp_dual_mode_read) (Paulo) Cc: stable@vger.kernel.org Cc: Tore Anderson Cc: Paulo Zanoni Cc: Shashank Sharma Cc: Daniel Vetter Cc: Shashank Sharma Signed-off-by: Ville Syrjälä Reviewed-by: Shashank Sharma (v4) Link: http://patchwork.freedesktop.org/patch/msgid/1462542412-25533-1-git-send-email-ville.syrjala@linux.intel.com (cherry picked from commit ede53344dbfd1dd43bfd73eb6af743d37c56a7c3) Signed-off-by: Jani Nikula

drm: Add Allwinner A10 Display Engine support

2016-04-28T08:30:05Z

The Allwinner A10 and subsequent SoCs share the same display pipeline, with variations in the number of controllers (1 or 2), or the presence or not of some output (HDMI, TV, VGA) or not. Add a driver with a limited set of features for now, and we will hopefully support all of them eventually Reviewed-by: Boris Brezillon Signed-off-by: Maxime Ripard

Misc stuff all over: - more mode_fixup removal from Carlos, there's another final pile still left. - final bits of vgaswitcheroo from Lukas for apple gmux, we're still discussing an api cleanup patch to make it a bit more abuse-safe as a follow-up - dp aux interface for userspace for tools&tests from Rafael Antognolli - actual interface parts for dma-buf flushing for userspace mmap - few small bits all over - vgaswitcheroo support for apple gmux from Lukas Wunner - checks for ->mode_fixup in non-atomic helpers from Carlos Palminha, plus removing dummy funcs from drivers. Carlos promised to follow up with more, since there's lots more silly dummy functions around. - dma-buf patches from Tiago, except the ioctl itself (that needed a respin to address review from David Herrmann) - encoder mask for atomic from Maarten - bunch of random things all over. * tag 'topic/drm-misc-2016-02-18' of git://anongit.freedesktop.org/drm-intel: (57 commits) drm/udl: Use module_usb_driver drm: fixes crct set_mode when crtc mode_fixup is null. drm/tilcdc: removed optional dummy encoder mode_fixup function. drm/sti: removed optional dummy encoder mode_fixup function. drm/rockchip: removed optional dummy encoder mode_fixup function. drm/qxl: removed optional dummy encoder mode_fixup function. drm/mgag200: removed optional dummy encoder mode_fixup function. drm/msm/mdp: removed optional dummy encoder mode_fixup function. drm/imx: removed optional dummy encoder mode_fixup function. drm/gma500: removed optional dummy encoder mode_fixup function. drm/radeon: removed optional dummy encoder mode_fixup function. drm/cirrus: removed optional dummy encoder mode_fixup function. drm/bochs: removed optional dummy encoder mode_fixup function. drm/ast: removed optional dummy encoder mode_fixup function. drm/amdgpu: removed optional dummy encoder mode_fixup function. drm/exynos: removed optional dummy encoder mode_fixup function. drm/udl: removed optional dummy encoder mode_fixup function. drm/virtio: removed optional dummy encoder mode_fixup function. drm/fb_helper: Use add_one_connector in add_all_connectors. drm/fb_helper: Use correct allocation count for arrays. ...

drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.

2016-02-12T13:22:40Z

This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the connector device pointer was correctly set in the aux helper struct. Two main operations are provided on the registers read and write. The address of the register to be read or written is given using lseek. The seek position is updated upon read or write. v2: - lseek is used to select the register to read/write - read/write are used instead of ioctl - no blocking_notifier is used, just a direct callback v3: - use drm_dp_aux_dev prefix for public functions - chardev is named drm_dp_auxN - read/write don't allocate a buffer anymore, and transfer up to 16 bytes a time - remove notifier list from the implementation - option on menuconfig is now a boolean - add inline stub functions to avoid breakage when this option is disabled v4: - fix build system changes - actually disable this module when not selected. v5: - Use kref to avoid device closing while still in use - Don't use list, use an idr for storing aux_dev - Remove "connector" attribute - set aux.dev to the connector drm_connector device, instead of drm_device v6: - Use atomic_t for usage count - Use a mutex instead of spinlock for idr lock - Destroy chardev immediately on unregister - other minor suggestions from Ville v7: - style fixes - error handling fixes v8: - more error handling fixes v9: - remove module_init and module_exit, and add drm_dp_aux_dev_init/exit to drm_kms_helper_init/exit.
