[PATCH] drm/tegra: dpaux: Make VDD supply optional
by Thierry Reding 05 Jun '19

05 Jun '19

From: Thierry Reding <treding(a)nvidia.com> The VDD supply is only needed to supply power to eDP panels connected to DPAUX. Technically that supply should be dealt with in the panel driver, but for backwards-compatibility we need to keep this around anyway. Also as a bit of background: the reason for why this supply is attached to DPAUX is to make sure the panel is properly powered early on so that it can generate a hotplug pulse at the appropriate time. This may no longer be required given the support for deferred fbdev setup that was "recently" introduced in DRM/KMS.

[PATCH] gpu: host1x: Do not link logical devices to DT nodes
by Thierry Reding 05 Jun '19

05 Jun '19

From: Thierry Reding <treding(a)nvidia.com> Logical devices created by the host1x bus infrastructure don't need to be associated with a device tree node. Doing so will cause the driver core to attempt to hook up IOMMU operations and fail because it is not a real device. However, for backwards-compatibility, we need to provide various OF_* uevent variables that were previously provided by of_device_uevent() and which are parsed by libdrm in userspace when querying the available devices. Do this by implementing a uevent callback for the host1x bus.

[PATCH] drm/tegra: Use GPIO descriptor API
by Thierry Reding 05 Jun '19

05 Jun '19

From: Thierry Reding <treding(a)nvidia.com> The legacy GPIO API has long been deprecated. Move the driver over to the descriptor-based API, which allows us to get rid of some boilerplate while at it.

[RESEND][PATCH v3 0/6] add LCD support for SAM9X60
by Claudiu.Beznea＠microchip.com 05 Jun '19

05 Jun '19

From: Claudiu Beznea <claudiu.beznea(a)microchip.com> Hi, These patches adds support for SAM9X60's LCD controller. First patches add option to specify if controller clock source is fixed. Second patch avoid a variable initialization in atmel_hlcdc_crtc_mode_set_nofb(). The 3rd add compatibles in pwm-atmel-hlcdc driver. The 4th patch enables sys_clk in probe since SAM9X60 needs this. Specific support was added also in suspend/resume hooks. The 5th patch adds SAM9X60's LCD configuration and enabled it. I took the changes of this series and introduced also a fix (this is the 6th patch in this series) - if you want to send it separately I would gladly do it. I resend this to also include Lee Jones for pwm-atmel-hlcdc changes. Thank you, Claudiu Beznea Changes in v3: - keep compatible string on patch 3/6 on a single line (I keep here a tab in front of ".compatible" to be aligned with the rest of the code in atmel_hlcdc_dt_ids[]) - patches 4/7 and 3/7 from v2 were applied so remove them from this version - add a fix for atmel_hlcdc (patch 6/6) Changes in v2: - use "|" operator in patch 1/7 to set ATMEL_HLCDC_CLKSEL on cfg - collect Acked-by, Reviewed-by tags Claudiu Beznea (4): drm: atmel-hlcdc: add config option for clock selection drm: atmel-hlcdc: avoid initializing cfg with zero pwm: atmel-hlcdc: add compatible for SAM9X60 HLCDC's PWM drm/atmel-hclcdc: revert shift by 8 Sandeep Sheriker Mallikarjun (2): drm: atmel-hlcdc: enable sys_clk during initalization. drm: atmel-hlcdc: add sam9x60 LCD controller drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_crtc.c | 18 ++-- drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c | 120 +++++++++++++++++++++++- drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.h | 2 + drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c | 2 +- drivers/pwm/pwm-atmel-hlcdc.c | 1 + 5 files changed, 132 insertions(+), 11 deletions(-) -- 2.7.4

[PATCH v2 0/2] drm/panel-simple: Add panel parameters for ortustech-com37h3m05dtc/99dtc and sharp-lq070y3dg3b
by H. Nikolaus Schaller 05 Jun '19

05 Jun '19

V2: * fix typo in 99dtc panel compatible string (reported by imirkin(a)alum.mit.edu) V1: Since v5.2-rc1 OMAP is no longer using a special display driver architecture for DPI panels, but uses the general drm/panel/panel-simple. So we finally can add SoC independent panel definitions for two panel models which we already had worked on quite a while ago (before device tree was introduced): https://patchwork.kernel.org/patch/2851295/ H.

[Bug 109955] amdgpu [RX Vega 64] system freeze while gaming
by bugzilla-daemon＠freedesktop.org 05 Jun '19

05 Jun '19

https://bugs.freedesktop.org/show_bug.cgi?id=109955 --- Comment #28 from Mauro Gaspari <ilvipero(a)gmx.com> --- Thanks all for adding comments and testing to this bug. I believe if we prove there is enough people affected on different cards, it will get the attention it needs, and hopefully a permanent mesa fix can be found and implemented. For those affected, if you don't mind testing the kernel parameters workaround i described above, and post your results, that would be a nice start. If you need help on how to do that you can reach out to me via PM or email. -- You are receiving this mail because: You are the assignee for the bug.
