2022-03-09drm/mediatek: implement the DSI HS packets alignedRex-BC Chen1-0/+12
Some DSI RX devices (for example, anx7625) require last alignment of packets on all lanes after each row of data is sent. Otherwise, there will be some issues of shift or scroll for screen. Take horizontal_sync_active_byte for a example, we roundup the HSA packet data to lane number, and the subtraction of 2 is the packet data value added by the roundup operation, making the long packets are integer multiples of lane number. This value (2) varies with the lane number, and that is the reason we do this operation when the lane number is 4. In the previous operation of function "mtk_dsi_config_vdo_timing", the length of HSA and HFP data packets has been adjusted to an integration multiple of lane number. Since the number of RGB data packets cannot be guaranteed to be an integer multiple of lane number, we modify the data packet length of HBP so that the number of HBP + RGB is equal to the lane number. So after sending a line of data (HSA + HBP + RGB + HFP), the data lanes are aligned.

This can be done during panel initialization (dsi is in command mode) or afterwards (dsi is in Video Mode). When the DSI is in Video Mode, all commands are rejected.

2022-02-09drm/mediatek: mtk_dsi: Avoid EPROBE_DEFER loop with external bridgeAngeloGioacchino Del Regno1-83/+84
DRM bridge drivers are now attaching their DSI device at probe time, which requires us to register our DSI host in order to let the bridge to probe: this recently started producing an endless -EPROBE_DEFER loop on some machines that are using external bridges, like the parade-ps8640, found on the ACER Chromebook R13. Now that the DSI hosts/devices probe sequence is documented, we can do adjustments to the mtk_dsi driver as to both fix now and make sure to avoid this situation in the future: for this, following what is documented in drm_bridge.c, move the mtk_dsi component_add() to the mtk_dsi_ops.attach callback and delete it in the detach callback; keeping in mind that we are registering a drm_bridge for our DSI, which is only used/attached if the DSI Host is bound, it wouldn't make sense to keep adding our bridge at probe time (as it would be useless to have it if mtk_dsi_ops.attach() fails!), so also move that one to the dsi host attach function (and remove it in detach).

2022-02-07dma-buf-map: Rename to iosys-mapLucas De Marchi2-5/+7
Rename struct dma_buf_map to struct iosys_map and corresponding APIs. Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include <linux/dma-buf-map.h> + #include <linux/iosys-map.h> Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map.

2021-12-13drm/mediatek: hdmi: Perform NULL pointer check for mtk_hdmi_confAngeloGioacchino Del Regno1-5/+7
In commit 41ca9caaae0b ("drm/mediatek: hdmi: Add check for CEA modes only") a check for CEA modes was added to function mtk_hdmi_bridge_mode_valid() in order to address possible issues on MT8167; moreover, with commit c91026a938c2 ("drm/mediatek: hdmi: Add optional limit on maximal HDMI mode clock") another similar check was introduced. Unfortunately though, at the time of writing, MT8173 does not provide any mtk_hdmi_conf structure and this is crashing the kernel with NULL pointer upon entering mtk_hdmi_bridge_mode_valid(), which happens as soon as a HDMI cable gets plugged in. To fix this regression, add a NULL pointer check for hdmi->conf in the said function, restoring HDMI functionality and avoiding NULL pointer kernel panics.

There are only minor changes, but they depend on other tegra driver updates here. - The ep93xx platform finally moves to using the drivers/clk/ subsystem, moving the code out of arch/arm in the process. This depends on a small sound driver change that is included here as well. - There are some minor updates for Qualcomm and Tegra specific firmware drivers. The other driver updates are mainly for drivers/soc, which contains a mixture of vendor specific drivers that don't really fit elsewhere: - Mediatek drivers gain more support for MT8192, with new support for hw-mutex and mmsys routing, plus support for reset lines in the mmsys driver. - Qualcomm gains a new "sleep stats" driver, and support for the "Generic Packet Router" in the APR driver. - There is a new user interface for routing the UARTS on ASpeed BMCs, something that apparently nobody else has needed so far. - More drivers can now be built as loadable modules, in particular for Broadcom and Samsung platforms. - Lots of improvements to the TI sysc driver for better suspend/resume support" Finally, there are lots of minor cleanups and new device IDs for amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape, allwinner, broadcom, and omap" * tag 'drivers-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (179 commits) optee: Fix spelling mistake "reclain" -> "reclaim" Revert "firmware: qcom: scm: Add support for MC boot address API" qcom: spm: allow compile-testing firmware: arm_ffa: Remove unused 'compat_version' variable soc: samsung: exynos-chipid: add exynosautov9 SoC support firmware: qcom: scm: Don't break compile test on non-ARM platforms soc: qcom: smp2p: Add of_node_put() before goto soc: qcom: apr: Add of_node_put() before return soc: qcom: qcom_stats: Fix client votes offset soc: qcom: rpmhpd: fix sm8350_mxc's peer domain dt-bindings: arm: cpus: Document qcom,msm8916-smp enable-method ARM: qcom: Add qcom,msm8916-smp enable-method identical to MSM8226 firmware: qcom: scm: Add support for MC boot address API soc: qcom: spm: Add 8916 SPM register data dt-bindings: soc: qcom: spm: Document qcom,msm8916-saw2-v3.0-cpu soc: qcom: socinfo: Add PM8150C and SMB2351 models firmware: qcom_scm: Fix error retval in __qcom_scm_is_call_available() soc: aspeed: Add UART routing support soc: fsl: dpio: rename the enqueue descriptor variable soc: fsl: dpio: use an explicit NULL instead of 0 ...
