24 Jun '22

From: ChiaEn Wu <chiaen_wu(a)richtek.com> This patch series add Mediatek MT6370 PMIC support. The MT6370 is a highly-integrated smart power management IC, which includes a single cell Li-Ion/Li-Polymer switching battery charger, a USB Type-C & Power Delivery (PD) controller, dual Flash LED current sources, a RGB LED driver, a backlight WLED driver, a display bias driver and a general LDO for portable devices. Among with this we took some changes and refined the device tree files to comply with DT specifications.

[PATCH v12 1/1] phy: phy-mtk-dp: Add driver for DP phy
by Bo-Chen Chen 24 Jun '22

24 Jun '22

From: Markus Schneider-Pargmann <msp(a)baylibre.com> This is a new driver that supports the integrated DisplayPort phy for mediatek SoCs, especially the mt8195. The phy is integrated into the DisplayPort controller and will be created by the mtk-dp driver. This driver expects a struct regmap to be able to work on the same registers as the DisplayPort controller. It sets the device data to be the struct phy so that the DisplayPort controller can easily work with it. The driver does not have any devicetree bindings because the datasheet does not list the controller and the phy as distinct units. The interaction with the controller can be covered by the configure callback of the phy framework and its displayport parameters.

[PATCH 0/5] Rework amdgpu HW fence refocunt and update scheduler parent fence refcount.
by Andrey Grodzovsky 24 Jun '22

24 Jun '22

Yiqing raised a problem of negative fence refcount for resubmitted jobs in amdgpu and suggested a workaround in [1]. I took a look myself and discovered some deeper problems both in amdgpu and scheduler code. Yiqing helped with testing the new code and also drew a detailed refcount and flow tracing diagram for parent (HW) fence life cycle and refcount under various cases for the proposed patchset at [2].

[git pull] drm fixes for 5.19-rc4
by Dave Airlie 24 Jun '22

24 Jun '22

Hi Linus, Fixes for this week, bit larger than normal, but I think the last couple have been quieter, and it's only rc4. There are a lot of small msm fixes, and a slightly larger set of vc4 fixes. The vc4 fixes clean up a lot of crashes around the rPI4 hardware differences from earlier ones, and problems in the page flip and modeset code which assumed earlier hw, so I thought it would be okay to keep them in. Otherwise, it's a few amdgpu, i915, sun4i and a panel quirk. Let me know if there are any issues. Just a headsup as well myself and danvet will be out the week 4th-10th July so you might not get an rc6 round, rc5 next week should be fine.

How do I gather up new code to be converted as patches?
by Kevin Brace 24 Jun '22

24 Jun '22

Hi, I spent about 2 days trying to figure this out, but I guess not a lot of people do this, so I was not able to find a good example somewhere on the Internet. How to I use git to gather up new code to be converted to patches? Specifically, I have 20+ new files in one location (drivers/gpu/drm/via) and a small change to DRM main make file (drivers/gpu/drm/Makefile). If someone can tell me how to do this, I will post the work on dri-devel. Regards, Kevin Brace Brace Computer Laboratory blog https://bracecomputerlab.com

[PATCH v2 00/96] Refactor non_legacy_dai_naming flag
by Charles Keepax 24 Jun '22

24 Jun '22

Historically, the legacy DAI naming scheme was applied to platform drivers and the newer scheme to CODEC drivers. During componentisation the core lost the knowledge of if a driver was a CODEC or platform, they were all now components. To continue to support the legacy naming on older platform drivers a flag was added to the snd_soc_component_driver structure, non_legacy_dai_naming, to indicate to use the new scheme and this was applied to all CODECs as part of the migration. However, a slight issue appears to be developing with respect to this flag being opt in for the non-legacy scheme, which presumably we want to be the primary scheme used. Many codec drivers appear to forget to include this flag: grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c | xargs grep -L "non_legacy_dai_naming" | wc 48 48 556 Whilst in many cases the configuration of the DAIs themselves will cause the core to apply the new scheme anyway, it would seem more sensible to change the flag to legacy_dai_naming making the new scheme opt out. This patch series migrates across to such a scheme.

[PATCH v14 00/15] drm/mediatek: Add MT8195 dp_intf driver
by Bo-Chen Chen 24 Jun '22

24 Jun '22

The dpi/dpintf driver and the added helper functions are required for the DisplayPort driver to work. This series is separated from [1] which is original from Guillaume. The display port driver is [2]. Changes for v14: 1. Separate a new binding patch to modify mediatek string format. 2. Use GENMASK(4, 0) for INT_MATRIX_SEL_MASK in patch "Add YUV422 output support" 3. Change kernel doc description of support_direct_pin. 4. Change to use pixels_per_iter to control quantity of transferred pixels per iterration. Changes for v13: 1. Change mediatek,mt8195-dp_intf to mediatek,mt8195-dp-intf. 2. Add kernel doc for mtk_dpi_conf. 3. Drop patch of tvd_pll enable. 4. Squash some color format transfer related patches. 5. Add new patch to support setting of direct connection to pins. 6. Change fix tag of "drm/mediatek: dpi: Only enable dpi after the bridge is enabled". Changes for v12: 1. Remove pll_gate. 2. Add more detailed commit message. 3. Separate tvd_clk patch and yuv422 output support from add dpintf support patch 4. Remove limit patch and use common driver codes to determine this. Changes for v11: 1. Rename ck_cg to pll_gate. 2. Add some commit message to clarify the modification reason. 3. Fix some driver order and modify for reviewers' comments.

[PATCH v5 0/9] usb: typec: Introduce typec-switch binding
by Prashant Malani 24 Jun '22

24 Jun '22

This series introduces a binding for Type-C data lane switches. These control the routing and operating modes of USB Type-C data lanes based on the PD messaging from the Type-C port driver regarding connected peripherals. The first 2 patches introduce the new "typec-switch" binding as well as one user of it (the ANX7625 drm bridge). Patches 3-5 add functionality to the anx7625 driver to register the mode-switches, as well as program its crosspoint switch depending on which Type-C port has a DisplayPort (DP) peripheral connected to it. Patch 6-9 add similar bindings update and Type-C switch support to the it6505 driver. v4: https://lore.kernel.org/linux-usb/20220615172129.1314056-8-pmalani@chromium… Changes in v5: - Rebased on usb-next, so removed Patch v4 1/7 and Patch v4 2/7 from this version (v5) since they are already in usb-next. - Added newer Reviewed-by tags. - Added new patches (6-9) in this version for a 2nd example (it6505) of a binding of the user. Patch submission suggestions: Option 1: - Bindings patches 1/9 and 2/9 can go through the USB repo (since they are already reviewed from v4 [1]). - Bindings patch 6/9 can go through the USB repo, and the remaining patches (3-5,7-9) can go through the DRM repo. <or> - Patches 3-9 can all go through the DRM repo. Option 2: - All patches (1-9) go through the USB repo. (My apologies if I've made this confusing, and I appreciate any suggestions for better submission strategy).

[PATCH RESEND] drm: i915: fix a possible refcount leak in intel_dp_add_mst_connector()
by Hangyu Hua 24 Jun '22

24 Jun '22

If drm_connector_init fails, intel_connector_free will be called to take care of proper free. So it is necessary to drop the refcount of port before intel_connector_free.
