2025-10-16drm/rockchip: dw_hdmi: use correct SCLIN mask for RK3228Alok Tiwari1-1/+1
In dw_hdmi_rk3228_setup_hpd(), the SCLIN mask incorrectly references the RK3328 variant. This change updates it to the RK3228-specific mask RK3228_HDMI_SCLIN_MSK using FIELD_PREP_WM16, ensuring proper HPD and I2C pin configuration for RK3228. Change: RK3328_HDMI_SCLIN_MSK -> RK3228_HDMI_SCLIN_MSK Fixes: 63df37f3fc71 ("drm/rockchip: dw_hdmi: switch to FIELD_PREP_WM16* macros") Signed-off-by: Alok Tiwari <alok.a.tiwari@oracle.com> Reviewed-by: Nicolas Frattaroli <nicolas.frattaroli@collabora.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Link: https://lore.kernel.org/r/20251010173143.72733-1-alok.a.tiwari@oracle.com

The vop2_plane_atomic_check() function incorrectly checks drm_rect_width(dest) twice instead of verifying both width and height. Fix the second condition to use drm_rect_height(dest) so that invalid destination rectangles with height < 4 are correctly rejected.

2025-09-02drm/rockchip: dw_hdmi: switch to FIELD_PREP_WM16* macrosNicolas Frattaroli1-44/+36
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. Remove this driver's very own HIWORD_UPDATE macro, and replace all instances of it with equivalent instantiations of FIELD_PREP_WM16 or FIELD_PREP_WM16_CONST, depending on whether it's in an initializer. This gives us better error checking, and a centrally agreed upon signature for this macro, to ease in code comprehension. Because FIELD_PREP_WM16/FIELD_PREP_WM16_CONST shifts the value to the mask (like FIELD_PREP et al do), a lot of macro instantiations get easier to read. This was tested on an RK3568 ODROID M1, as well as an RK3399 ROCKPro64.

2025-09-02drm/rockchip: inno-hdmi: switch to FIELD_PREP_WM16 macroNicolas Frattaroli1-6/+5
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. The inno-hdmi driver's own HIWORD_UPDATE macro is instantiated only twice. Remove it, and replace its uses with FIELD_PREP_WM16. Since FIELD_PREP_WM16 shifts the value for us, we replace using the mask as the value by simply using 1 instead. With the new FIELD_PREP_WM16 macro, we gain better error checking and a central shared definition. This has been compile-tested only as I lack hardware this old, but the change is trivial enough that I am fairly certain it's equivalent.

2025-09-02drm/rockchip: dw_hdmi_qp: switch to FIELD_PREP_WM16 macroNicolas Frattaroli1-35/+33
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. Replace this driver's HIWORD_UPDATE with the FIELD_PREP_WM16 macro from hw_bitfield.h. While at it, disambiguate the GRF write to SOC_CON7 by splitting the definition into the individual bitflags. This is done because FIELD_PREP_WM16 shifts the value for us according to the mask, so writing the mask to itself to enable two bits is no longer something that can be done. It should also not be done anyway because it hides the true meaning of those two individual bit flags. HDMI output with this patch has been tested on both RK3588 and RK3576. On the former, with both present HDMI connectors.

Remove VOP2's HIWORD_UPDATE macro from the vop2 header file, and replace all instances in rockchip_vop2_reg.c (the only user of this particular HIWORD_UPDATE definition) with equivalent FIELD_PREP_WM16 instances.

2025-09-02drm/rockchip: dsi: switch to FIELD_PREP_WM16* macrosNicolas Frattaroli1-74/+68
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. Remove this driver's HIWORD_UPDATE macro, and replace instances of it with either FIELD_PREP_WM16 or FIELD_PREP_WM16_CONST, depending on whether they're in an initializer. This gives us better error checking, which already saved me some trouble during this refactor. The driver's HIWORD_UPDATE macro doesn't shift up the value, but expects a pre-shifted value. Meanwhile, FIELD_PREP_WM16 and FIELD_PREP_WM16_CONST will shift the value for us, based on the given mask. So a few things that used to be a HIWORD_UPDATE(VERY_LONG_FOO, VERY_LONG_FOO) are now a somewhat more pleasant FIELD_PREP_WM16(VERY_LONG_FOO, 1). There are some non-trivial refactors here. A few literals needed a UL suffix added to stop them from unintentionally overflowing as a signed long. To make sure all of these cases are caught, and not just the ones where the FIELD_PREP_WM16* macros use such a value as a mask, just mark every literal that's used as a mask as unsigned. Non-contiguous masks also have to be split into multiple FIELD_PREP_WM16* instances, as the macro's checks and shifting logic rely on contiguous masks. This is compile-tested only.

2025-08-14drm/rockchip: vop2: make vp registers nonvolatilePiotr Zalewski1-4/+5
Make video port registers nonvolatile. As DSP_CTRL register is written to twice due to gamma LUT enable bit which is set outside of the main DSP_CTRL initialization within atomic_enable (for rk356x case it is also necessary to always disable gamma LUT before writing a new LUT) there is a chance that DSP_CTRL value read-out in gamma LUT init/update code is not the one which was written by the preceding DSP_CTRL initialization code within atomic_enable. This might result in misconfigured DSP_CTRL which leads to no visual output[1]. Since DSP_CTRL write takes effect after VSYNC[1] the issue is not always present. When tested on Pinetab2 with kernel 6.14 it happenes only when DRM is compiled as a module[1]. In order to confirm that it is a timing issue I inserted 18ms udelay before vop2_crtc_atomic_try_set_gamma in atomic enable and compiled DRM as module - this has also fixed the issue.

2025-07-14drm/bridge: Pass down connector to drm bridge detect hookAndy Yan2-2/+2
In some application scenarios, we hope to get the corresponding connector when the bridge's detect hook is invoked. In most cases, we can get the connector by drm_atomic_get_connector_for_encoder if the encoder attached to the bridge is enabled, however there will still be some scenarios where the detect hook of the bridge is called but the corresponding encoder has not been enabled yet. For instance, this occurs when the device is hot plug in for the first time. Since the call to bridge's detect is initiated by the connector, passing down the corresponding connector directly will make things simpler.

2025-07-08drm/rockchip: vop2: Fix the update of LAYER/PORT select registers when there ↵Andy Yan3-25/+122
are multi display output on rk3588/rk3568 The all video ports of rk3568/rk3588 share the same OVL_LAYER_SEL and OVL_PORT_SEL registers, and the configuration of these two registers can be set to take effect when the vsync signal arrives at a certain Video Port. If two threads for two display output choose to update these two registers simultaneously to meet their own plane adjustment requirements(change plane zpos or switch plane from one crtc to another), then no matter which Video Port'svsync signal we choose to follow for these two registers, the display output of the other Video Port will be abnormal. This is because the configuration of this Video Port does not take effect at the right time (its configuration should take effect when its VSYNC signal arrives). In order to solve this problem, when performing plane migration or change the zpos of planes, there are two things to be observed and followed: 1. When a plane is migrated from one VP to another, the configuration of the layer can only take effect after the Port mux configuration is enabled. 2. When change the zpos of planes, we must ensure that the change for the previous VP takes effect before we proceed to change the next VP. Otherwise, the new configuration might overwrite the previous one for the previous VP, or it could lead to the configuration of the previous VP being take effect along with the VSYNC of the new VP. This issue only occurs in scenarios where multi-display output is enabled.

Each window of a vop2 is usable by a specific set of video ports, so while binding the vop2, we look through the list of available windows trying to find one designated as primary-plane and usable by that specific port. The code later wants to use drm_crtc_init_with_planes with that found primary plane, but nothing has checked so far if a primary plane was actually found. For whatever reason, the rk3576 vp2 does not have a usable primary window (if vp0 is also in use) which brought the issue to light and ended in a null-pointer dereference further down. As we expect a primary-plane to exist for a video-port, add a check at the end of the window-iteration and fail probing if none was found.

2025-03-04drm/rockchip: lvds: lower log severity for missing pinctrl settingsHeiko Stuebner1-2/+2
While missing lvds pinctrl is unexpected and is reported, we nevertheless don't fail setting up the device and instead continue without explicit pinctrl handling. So lower the log-level from error to warning to reflect that.

2025-03-04drm/rockchip: lvds: Hide scary error messages on probe deferralHeiko Stuebner1-36/+27
Commit 52d11c863ac9 ("drm/rockchip: lvds: do not print scary message when probing defer") already started hiding scary messages that are not relevant if the requested supply just returned EPROBE_DEFER, but there are more possible sources - like the phy. So modernize the whole logging in the probe path by replacing the remaining deprecated DRM_DEV_ERROR with appropriate dev_err(_probe) and drm_err calls. The distinction here is that all messages talking about mishaps of the lvds element use dev_err(_probe) while messages caused by interaction with the main Rockchip drm-device use drm_err.

2025-03-04drm/rockchip: lvds: move pclk preparation in with clk_getHeiko Stuebner1-16/+3
The LVDS block needs a separate pclk only on some socs, so currently requests and prepares it in the soc-specific probe function, but common code is required to unprepare it in the error path or on driver remove. While this works because clk_unprepare just does nothing if clk is NULL, this mismatch of who is responsible still is not very nice. The clock-framework already has a helper for clk-get-and-prepare even with devres support in devm_clk_get_prepared(). This will get and prepare the clock and also unprepare it on driver removal, saving the driver from having to handle it "manually".
