2020-03-25drm/exynos: dsi: fix workaround for the legacy clock nameMarek Szyprowski
[ Upstream commit c0fd99d659ba5582e09625c7a985d63fc2ca74b5 ] Writing to the built-in strings arrays doesn't work if driver is loaded as kernel module. This is also considered as a bad pattern. Fix this by adding a call to clk_get() with legacy clock name. This fixes following kernel oops if driver is loaded as module: Unable to handle kernel paging request at virtual address bf047978 pgd = (ptrval) [bf047978] *pgd=59344811, *pte=5903c6df, *ppte=5903c65f Internal error: Oops: 80f [#1] SMP ARM Modules linked in: mc exynosdrm(+) analogix_dp rtc_s3c exynos_ppmu i2c_gpio CPU: 1 PID: 212 Comm: systemd-udevd Not tainted 5.6.0-rc2-next-20200219 #326 videodev: Linux video capture interface: v2.00 Hardware name: Samsung Exynos (Flattened Device Tree) PC is at exynos_dsi_probe+0x1f0/0x384 [exynosdrm] LR is at exynos_dsi_probe+0x1dc/0x384 [exynosdrm] ...

2019-04-20drm/exynos/mixer: fix MIXER shadow registry synchronisation codeAndrzej Hajda
[ Upstream commit 6a3b45ada960ac475ec2b4103d43e57943b2b8d3 ] MIXER on Exynos5 SoCs uses different synchronisation method than Exynos4 to update internal state (shadow registers). Apparently the driver implements it incorrectly. The rule should be as follows: - do not request updating registers until previous request was finished, ie. MXR_CFG_LAYER_UPDATE_COUNT must be 0. - before setting registers synchronisation on VSYNC should be turned off, ie. MXR_STATUS_SYNC_ENABLE should be reset, - after finishing MXR_STATUS_SYNC_ENABLE should be set again. The patch hopefully implements it correctly.

2018-11-27Revert "drm/exynos/decon5433: implement frame counter"Inki Dae
[ Upstream commit 6ca469e22a30992b4478d2ab88737c70667c1e00 ] This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b This patch makes it to need get_vblank_counter callback in crtc to get frame counter from decon driver. However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.

2018-07-24drm/exynos: Ensure suspended runtime PM state during system suspendMarek Szyprowski
Add calls to pm_runtime_force_{suspend,resume} as SYSTEM_SLEEP_PM_OPS for all drivers for the real Exynos DRM hardware modules. This ensures that the resources will be released for the system PM suspend/resume cycle. Exynos DRM core already takes care of suspending the whole display pipeline before PM callbacks of the real devices are called.

2018-07-24drm/exynos: Suspend/resume display pipeline as early/late as possibleMarek Szyprowski
In the current code, exynos_drm_suspend() function is called after all real devices (CRTCs, Encoders, etc) are suspended, because Exynos DRM virtual platform device is created as last device in the system (as a part of DRM registration). None of the devices for real hardware modules has its own system suspend/resume callbacks, so it doesn't change any order of the executed code, but it has a side-effect: runtime PM callbacks for real devices are not executed, because those devices are considered by PM core as already suspended. This might cause issues on boards with complex pipelines, where something depends on the runtime PM state of the given device. To ensure that exynos_drm_suspend() is called before any suspend callback from the real devices, assign it to .prepare callback. Same for exynos_drm_resume(), using .complete callback ensures that all real devices have been resumed when calling it.

Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.

2018-06-12treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Add more HW overlays support - It enables hardware overlay number 4 and 5. For this, this patch series adds required clocks. Several fixups - Fix default value of zpos according to real hardware overlay number. - Fix error value of exynos_Drm_crtc_get_by_type function correctly. - Fix static checker warning of scaler_task_done function. - Fix signedness bug in fimc_setup_clocks function. One cleanup - Disable framedone interrupt of DSI device which is not required.

DSI driver is not really interested in this interrupt. It causes only unnecessary code execution of interrupt handler and could possibly cause FIFO overflow - as it triggers DSI interrupt handler to process next DSI transfer. With this patch we will get rid of about 30 IRQ handler calls per second.

Enable support for 2 more hardware windows. This require enabling a few more clocks and set proper plane type for all windows. In the new configuration primary plane uses hardware window no 3 and cursor uses window no 5. The remaining hardware windows are used for overlays. This gives us an overlay plane both below and above primary plane for both Decon and DeconTV (which uses hardware window nr 0 for background).

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next - Add S5PV210 FIMD variant support. - Add IPP v2 framework. . it is a rewritten version of the Exynos mem-to-mem image processing framework which supprts color space conversion, image up/down-scaling and rotation. This new version replaces existing userspace API with new easy-to-use and simple ones so we have already applied the use of these API to real user, Tizen Platform[1], and also makes existing Scaler, FIMC, GScaler and Rotator drivers to use IPP v2 core API. And below are patch lists we have applied to a real user, https://git.tizen.org/cgit/platform/adaptation/samsung_exynos/libtdm-exynos/log/?h=tizen&qt=grep&q=ipp https://git.tizen.org/cgit/platform/adaptation/samsung_exynos/libtdm-exynos/commit/?h=tizen&id=b59be207365d10efd489e6f71c8a045b558c44fe https://git.tizen.org/cgit/platform/kernel/linux-exynos/log/?h=tizen&qt=grep&q=ipp TDM(Tizen Display Manager) is a Display HAL for Tizen platform. Ps. Only real user using IPP API is Tizen. [1] https://www.tizen.org/ - Two cleanups . One is to just remove mode_set callback from MIPI-DSI driver because drm_display_mode data is already available from crtc atomic state. . And other is to just use new return type, vm_fault_t for page fault handler.
