2016-05-23drm/imx: Match imx-ipuv3-crtc components using device node in platform dataPhilipp Zabel
The component master driver imx-drm-core matches component devices using their of_node. Since commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading"), the imx-ipuv3-crtc dev->of_node is not set during probing. Before that, of_node was set and caused an of: modalias to be used instead of the platform: modalias, which broke module autoloading. On the other hand, if dev->of_node is not set yet when the imx-ipuv3-crtc probe function calls component_add, component matching in imx-drm-core fails. While dev->of_node will be set once the next component tries to bring up the component master, imx-drm-core component binding will never succeed if one of the crtc devices is probed last. Add of_node to the component platform data and match against the pdata->of_node instead of dev->of_node in imx-drm-core to work around this problem.

2016-05-23mmc: dw_mmc: rockchip: Set the drive phase properlyDouglas Anderson
Historically for Rockchip devices we've relied on the power-on default (or perhaps the firmware setting) to get the correct drive phase for dw_mmc devices. This worked OK for the most part, but: * Relying on the setting just "being right" is a bit fragile. * As soon as there is an instance where the power on default is wrong or where the firmware didn't configure this properly then we'll get a mysterious failure. In commit 7a03fe6f48f3 ("clk: rockchip: reset init state before mmc card initialization") we actually started setting this explicitly in the kernel, but that commit wasn't quite right and also wasn't quite enough. See <https://patchwork.kernel.org/patch/9085311/> for some details. Let's explicitly set this phase in dw_mmc. The comments inside this patch try to explain the situation quite throughly, but the high level overview of this is: Before this patch on rk3288 devices tested (after revert of the clock patch described above): * eMMC: 180 degrees * SDMMC/SDIO0/SDIO1: 90 degrees After this patch: * Use 90 degree phase offset usually. * Use 180 degree phase offset for MMC_DDR52, SDR104, HS200. That means we are _changing_ behavior for those devices in this way: * If we have HS200 eMMC or DDR52 eMMC, we'll run ID mode at 90 degrees (vs 180) but otherwise have no change. * For any non-HS200 / non-DDR52 eMMC devices we'll now _always_ run at 90 degrees (vs 180). It seems fairly unlikely that building modern hardware is using an eMMC that isn't using DDR52 or HS200, of course. * For SDR104 cards we'll now run with 180 degree phase offset (vs 90). It's expected that 90 degree phase offset would have worked OK, but this gives us extra margin. I have tested this by inserting my collection of uSD cards (mostly UHS, though a few not) into a veyron_minnie and confirmed that they still seem to enumerate properly. For a subset of them I tried putting a filesystem on them and also tried running mmc_test.

2016-05-23drm/i915/bxt: Adjusting the error in horizontal timings retrievalRamalingam C
In BXT DSI there is no regs programmed with few horizontal timings in Pixels but txbyteclkhs.. So retrieval process adds some ROUND_UP ERRORS in the process of PIXELS<==>txbyteclkhs. Actually here for the given adjusted_mode, we are calculating the value programmed to the port and then back to the horizontal timing param in pixels. This is the expected value at the end of get_config, including roundup errors. And if that is same as retrieved value from port, then retrieved (HW state) adjusted_mode's horizontal timings are corrected to match with SW state to nullify the errors.

When we read out the watermark state from the hardware we're supposed to transfer that into the active watermarks, but currently we fail to any part of the active watermarks that isn't explicitly written.

2016-05-23drm/i915: Re-enable GGTT earlier during resume on pre-gen6 platformsVille Syrjälä
Move the intel_enable_gtt() call to happen before we touch the GTT during resume. Right now it's done way too late. Before commit ebb7c78d358b ("agp/intel-gtt: Only register fake agp driver for gen1") it was actually done earlier on account of also getting called from the resume hook of the fake agp driver. With the fake agp driver no longer getting registered we must move the call up. The symptoms I've seen on my 830 machine include lowmem corruption, other kinds of memory corruption, and straight up hung machine during or just after resume. Not really sure what causes the memory corruption, but so far I've not seen any with this fix. I think we shouldn't really need to call this during init, but we have been doing that so I've decided to keep the call. However moving that call earlier could be prudent as well. Doing it right after the intel-gtt probe seems appropriate. Also tested this on 946gz,elk,ilk and all seemed quite happy with this change. v2: Reorder init_hw vs. enable_hw functions (Chris) Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: drm-intel-fixes@lists.freedesktop.org Fixes: ebb7c78d358b ("agp/intel-gtt: Only register fake agp driver for gen1") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1462559755-353-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> (cherry picked from commit ac840ae53573d9f435c88c131f6707a79aecb466) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2016-05-23drm/i915: Respect DP++ adaptor TMDS clock limitVille Syrjälä
Try to detect the max TMDS clock limit for the DP++ adaptor (if any) and take it into account when checking the port clock. Note that as with the sink (HDMI vs. DVI) TMDS clock limit we'll ignore the adaptor TMDS clock limit in the modeset path, in case users are already "overclocking" their TMDS links. One subtle change here is that we'll have to respect the adaptor TMDS clock limit when we decide whether to do 12bpc or 8bpc, otherwise we might end up picking 12bpc and accidentally driving the TMDS link out of spec even when the user chose a mode that fits wihting the limits at 8bpc. This means you can't "overclock" your DP++ dongle at 12bpc anymore, but you can continue to do so at 8bpc. Note that for simplicity we'll use the I2C access method for all dual mode adaptors including type 2. Otherwise we'd have to start mixing DP AUX and HDMI together. In the future we may need to do that if we come across any board designs that don't hook up the DDC pins to the DP++ connectors. Such boards would obviously only work with type 2 dual mode adaptors, and not type 1. v2: Store adaptor type under indel_hdmi->dp_dual_mode Deal with DRM_DP_DUAL_MODE_UNKNOWN Pass adaptor type to drm_dp_dual_mode_max_tmds_clock(), and use it for type1 adaptors as well Cc: stable@vger.kernel.org Reported-by: Tore Anderson <tore@fud.no> Fixes: 7a0baa623446 ("Revert "drm/i915: Disable 12bpc hdmi for now"") Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1462216105-20881-3-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> (cherry picked from commit b1ba124d8e95cca48d33502a4a76b1ed09d213ce) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-05-23drm: Add helper for DP++ adaptorsVille Syrjälä
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 <tore@fud.no> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> (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 <jani.nikula@intel.com>

2016-05-22x86: remove pointless uaccess_32.h complexityLinus Torvalds
I'm looking at trying to possibly merge the 32-bit and 64-bit versions of the x86 uaccess.h implementation, but first this needs to be cleaned up. For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly the special cases for the constant size, and it's actually never relevant. Every user except for one aren't actually using a constant size anyway, and the one user that uses it is better off just using __put_user() instead. So get rid of the unnecessary complexity.

Otherwise the alignment check is useless in the implicit case and only the minimum size of the offset matters. This self-consistency check is further validated by the probe path that will re-check that the offset is large enough to contain all the metadata required to enable the device.
