Save pll state before dsi host is powered off. Without this change some register values gets resetted. Signed-off-by: Harigovindan P Signed-off-by: Rob Clark

drm/msm/dsi: Add configuration for 28nm PLL on family B

2019-11-04T21:17:42Z

The 28nm PLL has a different iospace on MSM/APQ family B SoCs: add a new configuration and use it when the DT reports the "qcom,dsi-phy-28nm-hpm-fam-b" compatible. Signed-off-by: AngeloGioacchino Del Regno Signed-off-by: Rob Clark

drm/msm/dsi: Implement qcom, dsi-phy-regulator-ldo-mode for 28nm PHY

2019-10-24T19:08:12Z

The DSI PHY regulator supports two regulator modes: LDO and DCDC. This mode can be selected using the "qcom,dsi-phy-regulator-ldo-mode" device tree property. However, at the moment only the 20nm PHY driver actually implements that option. Add a check in the 28nm PHY driver to program the registers correctly for LDO mode.

drm/msm/phy/dsi_phy: silence -EPROBE_DEFER warnings

2019-09-03T23:16:58Z

The following errors show up when booting the Nexus 5: msm_dsi_phy fd922a00.dsi-phy: [drm:dsi_phy_driver_probe] *ERROR* dsi_phy_regulator_init: failed to init regulator, ret=-517 msm_dsi_phy fd922a00.dsi-phy: [drm:dsi_phy_driver_probe] *ERROR* dsi_phy_driver_probe: failed to init regulator dsi_phy_regulator_init() already logs the error, so no need to log the same error a second time in dsi_phy_driver_probe(). This patch also changes dsi_phy_regulator_init() to not log the error if the error code is -EPROBE_DEFER to reduce noise in dmesg.

drm/msm: drop use of drmP.h

2019-09-03T23:16:57Z

Drop the deprecated drmP.h header file, and trim msm_drv.h to the relevant include files. This resulted in a suprisingly many edits as many files relied on headers included via msm_drv.h. But msm_drv.h is not supposed to carry include files it do not need, so the individual files have to include what extra they needs. v2: - Rebased on top of https://gitlab.freedesktop.org/drm/msm.git msm-next Signed-off-by: Sam Ravnborg Cc: Rob Clark Cc: Sean Paul Cc: David Airlie Cc: Daniel Vetter Cc: Jordan Crouse Cc: Jeykumar Sankaran Cc: Bruce Wang Cc: Shayenne Moura Cc: Mamta Shukla Cc: Jonathan Marek Cc: Carsten Behling Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Paul Kocialkowski Cc: Sibi Sankar Cc: Todor Tomov Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/20190804065551.GA5211@ravnborg.org

Merge tag 'drm-msm-next-2019-06-25' of https://gitlab.freedesktop.org/drm/msm into drm-next

2019-06-28T00:16:40Z

+ usual progress on cleanups + dsi vs EPROBE_DEFER fixes + msm8998 (snapdragon 835 support) + a540 gpu support (mesa support already landed) + dsi, dsi-phy support + mdp5 and dpu interconnect (bus/memory scaling) support + initial prep work for per-context pagetables (at least the parts that don't have external dependencies like iommu/arm-smmu) There is one more patch for fixing DSI cmd mode panels (part of a set of patches to get things working on nexus5), but it would be conflicty with 1cff7440a86e04a613665803b42034 in drm-next without rebasing or back-merge, and since it doesn't conflict with anything in msm-next, I think it best if Sean merges that through drm-mix-fixes instead. (In other news, I've been making some progress w/ getting efifb working properly on sdm850 laptop without horrible hacks, and drm/msm + clk stuff not totally falling over when bootloader enables display and things are already running when driver probes.. but not quite ready yet, hopefully we can post some of that for 5.4.. should help for both the sdm835 and sdm850 laptops.)

drm/msm/dsi: Add old timings quirk for 10nm phy

2019-06-18T20:56:43Z

The v3.0.0 10nm phy has two different implementations between MSM8998 and SDM845, which require different timings calculations. Unfortunately, the hardware designers did not choose to revise the version to account for this delta so implement a quirk instead. Signed-off-by: Jeffrey Hugo Signed-off-by: Rob Clark
