drm/bridge/synopsys: dw-hdmi: fix dw_hdmi_setup_rx_sense

2018-05-30T17:42:39Z

The dw_hdmi_setup_rx_sense exported function should not use struct device to recover the dw-hdmi context using drvdata, but take struct dw_hdmi directly like other exported functions. This caused a regression using Meson DRM on S905X since v4.17-rc1 : Internal error: Oops: 96000007 [#1] PREEMPT SMP [...] CPU: 0 PID: 124 Comm: irq/32-dw_hdmi_ Not tainted 4.17.0-rc7 #2 Hardware name: Libre Technology CC (DT) [...] pc : osq_lock+0x54/0x188 lr : __mutex_lock.isra.0+0x74/0x530 [...] Process irq/32-dw_hdmi_ (pid: 124, stack limit = 0x00000000adf418cb) Call trace: osq_lock+0x54/0x188 __mutex_lock_slowpath+0x10/0x18 mutex_lock+0x30/0x38 __dw_hdmi_setup_rx_sense+0x28/0x98 dw_hdmi_setup_rx_sense+0x10/0x18 dw_hdmi_top_thread_irq+0x2c/0x50 irq_thread_fn+0x28/0x68 irq_thread+0x10c/0x1a0 kthread+0x128/0x130 ret_from_fork+0x10/0x18 Code: 34000964 d00050a2 51000484 9135c042 (f864d844) ---[ end trace 945641e1fbbc07da ]--- note: irq/32-dw_hdmi_[124] exited with preempt_count 1 genirq: exiting task "irq/32-dw_hdmi_" (124) is an active IRQ thread (irq 32) Fixes: eea034af90c6 ("drm/bridge/synopsys: dw-hdmi: don't clobber drvdata") Signed-off-by: Neil Armstrong Tested-by: Koen Kooi Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/1527673438-20643-1-git-send-email-narmstrong@baylibre.com

Backmerge tag 'v4.16-rc7' into drm-next

Linux 4.16-rc7 This was requested by Daniel, and things were getting a bit hard to reconcile, most of the conflicts were trivial though.

drm/meson: Fix potential NULL dereference in meson_drv_bind_master()

2018-03-20T16:15:40Z

platform_get_resource_byname() may fail and return NULL, so we should better check it's return value to avoid a NULL pointer dereference a bit later in the code. This is detected by Coccinelle semantic patch. @@ expression pdev, res, n, t, e, e1, e2; @@ res = platform_get_resource_byname(pdev, t, n); + if (!res) + return -EINVAL; ... when != res == NULL e = devm_ioremap(e1, res->start, e2); Signed-off-by: Wei Yongjun Signed-off-by: Neil Armstrong Acked-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/1521555630-29284-1-git-send-email-weiyongjun1@huawei.com

drm/meson: Add support for DMT modes on HDMI

2018-03-13T10:50:23Z

This patch adds support for DMT display modes over HDMI. The modes timings configurations are from the Amlogic Vendor linux tree and tested over multiples monitors. Previously only a selected number of CEA modes were supported. Only these following modes are supported with these changes: - 640x480@60Hz - 800x600@60Hz - 1024x768@60Hz - 1152x864@75Hz - 1280x1024@60Hz - 1600x1200@60Hz - 1920x1080@60Hz The associated code to handle the clock rates is also added.

drm/meson: Use drm_dev_put() instead of drm_dev_unref()

2018-03-13T09:38:28Z

According to 'drivers/gpu/drm/drm_drv.c', 'drm_dev_unref()' is just a compatibility alias for 'drm_dev_put()'. So use the latter instead.

drm/meson: fix vsync buffer update

2018-02-20T09:03:52Z

The plane buffer address/stride/height was incorrectly updated in the plane_atomic_update operation instead of the vsync irq. This patch delays this operation in the vsync irq along with the other plane delayed setup. This issue was masked using legacy framebuffer and X11 modesetting, but is clearly visible using gbm rendering when buffer is submitted late after vblank, like using software decoding and OpenGL rendering in Kodi. With this patch, tearing and other artifacts disappears completely.
