2019-07-29video: fbdev: mxsfb: Fix flags not being appliedPhilippe Schenker
If one used display timings in devicetree the display_flags like pixelclk-active have not been applied. This commit fixes that and puts some nice debug messages so one can see from where those timings are applied. This fixes commit f397f60efbb24c2906cd95f443607b2642b49b24 "video: fbdev: mxsfb: allow setting display timings via kernel command line" Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> (cherry picked from commit 17652e758b1236c49d2e1d336d81a832452b7c53)
2019-07-29Revert "video: fbdev: mxsfb: honor native-mode"Philippe Schenker
This commit should not be in 4.14 and was accidentally introduced from 4.1 to 4.9 merge. It originally was deleted with commit: "f397f60e video: fbdev: mxsfb: allow setting display timings via kernel command line" This reverts commit 721dee144c883aebd6e997a53eed3ab3c24cef79.
2019-07-02Video: backlight: Enable backlight in any casePhilippe Schenker
This patch enables the backlight in any case. Mainline assumes now that backlight is turned on from an appropriate driver to get flickerless backlight experience. Theres no such thing in downstream, so get rid of the code part that blocks backlight from turning on. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2019-05-24video: fbdev: mxsfb: honor native-modeStefan Agner
Honor the native-mode property by adding only that mode to the mode list. With that we loose the list of modes, but we currently don't make use of it anyway. Also, the mode list lacks the pixel clock polarity information since struct fb_videomode does not store this information.

2019-05-24video: fbdev: mxsfb: fix pixelclock polarityStefan Agner
The PIXDATA flags of the display_flags enum are controller centric, e.g. NEGEDGE means the controller shall drive the data signals on pixelclocks negative edge. However, the drivers flag is display centric: Sample the data on negative (falling) edge. Therefore, change the if statement to check for the POSEDGE flag (which is typically not set): Drive on positive edge => sample on negative edge Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com> (cherry picked from commit 5652dc1ad78303fb246f050ba23c563319d823cf)

[ Upstream commit 2122b40580dd9d0620398739c773d07a7b7939d0 ] When unregistering fbdev using unregister_framebuffer(), any bound console will unbind automatically. This is working fine if this is the only framebuffer, resulting in a switch to the dummy console. However if there is a fb0 and I unregister fb1 having a bound console, I eventually get a crash. The fastest way for me to trigger the crash is to do a reboot, resulting in this splat: [ 76.478825] WARNING: CPU: 0 PID: 527 at linux/kernel/workqueue.c:1442 __queue_work+0x2d4/0x41c [ 76.478849] Modules linked in: raspberrypi_hwmon gpio_backlight backlight bcm2835_rng rng_core [last unloaded: tinydrm] [ 76.478916] CPU: 0 PID: 527 Comm: systemd-udevd Not tainted 4.20.0-rc4+ #4 [ 76.478933] Hardware name: BCM2835 [ 76.478949] Backtrace: [ 76.478995] [<c010d388>] (dump_backtrace) from [<c010d670>] (show_stack+0x20/0x24) [ 76.479022] r6:00000000 r5:c0bc73be r4:00000000 r3:6fb5bf81 [ 76.479060] [<c010d650>] (show_stack) from [<c08e82f4>] (dump_stack+0x20/0x28) [ 76.479102] [<c08e82d4>] (dump_stack) from [<c0120070>] (__warn+0xec/0x12c) [ 76.479134] [<c011ff84>] (__warn) from [<c01201e4>] (warn_slowpath_null+0x4c/0x58) [ 76.479165] r9:c0eb6944 r8:00000001 r7:c0e927f8 r6:c0bc73be r5:000005a2 r4:c0139e84 [ 76.479197] [<c0120198>] (warn_slowpath_null) from [<c0139e84>] (__queue_work+0x2d4/0x41c) [ 76.479222] r6:d7666a00 r5:c0e918ee r4:dbc4e700 [ 76.479251] [<c0139bb0>] (__queue_work) from [<c013a02c>] (queue_work_on+0x60/0x88) [ 76.479281] r10:c0496bf8 r9:00000100 r8:c0e92ae0 r7:00000001 r6:d9403700 r5:d7666a00 [ 76.479298] r4:20000113 [ 76.479348] [<c0139fcc>] (queue_work_on) from [<c0496c28>] (cursor_timer_handler+0x30/0x54) [ 76.479374] r7:d8a8fabc r6:c0e08088 r5:d8afdc5c r4:d8a8fabc [ 76.479413] [<c0496bf8>] (cursor_timer_handler) from [<c0178744>] (call_timer_fn+0x100/0x230) [ 76.479435] r4:c0e9192f r3:d758a340 [ 76.479465] [<c0178644>] (call_timer_fn) from [<c0178980>] (expire_timers+0x10c/0x12c) [ 76.479495] r10:40000000 r9:c0e9192f r8:c0e92ae0 r7:d8afdccc r6:c0e19280 r5:c0496bf8 [ 76.479513] r4:d8a8fabc [ 76.479541] [<c0178874>] (expire_timers) from [<c0179630>] (run_timer_softirq+0xa8/0x184) [ 76.479570] r9:00000001 r8:c0e19280 r7:00000000 r6:c0e08088 r5:c0e1a3e0 r4:c0e19280 [ 76.479603] [<c0179588>] (run_timer_softirq) from [<c0102404>] (__do_softirq+0x1ac/0x3fc) [ 76.479632] r10:c0e91680 r9:d8afc020 r8:0000000a r7:00000100 r6:00000001 r5:00000002 [ 76.479650] r4:c0eb65ec [ 76.479686] [<c0102258>] (__do_softirq) from [<c0124d10>] (irq_exit+0xe8/0x168) [ 76.479716] r10:d8d1a9b0 r9:d8afc000 r8:00000001 r7:d949c000 r6:00000000 r5:c0e8b3f0 [ 76.479734] r4:00000000 [ 76.479764] [<c0124c28>] (irq_exit) from [<c016b72c>] (__handle_domain_irq+0x94/0xb0) [ 76.479793] [<c016b698>] (__handle_domain_irq) from [<c01021dc>] (bcm2835_handle_irq+0x3c/0x48) [ 76.479823] r8:d8afdebc r7:d8afddfc r6:ffffffff r5:c0e089f8 r4:d8afddc8 r3:d8afddc8 [ 76.479851] [<c01021a0>] (bcm2835_handle_irq) from [<c01019f0>] (__irq_svc+0x70/0x98) The problem is in the console rebinding in fbcon_fb_unbind().

2019-02-12fbdev: fbmem: behave better with small rotated displays and many CPUsPeter Rosin
[ Upstream commit f75df8d4b4fabfad7e3cba2debfad12741c6fde7 ] Blitting an image with "negative" offsets is not working since there is no clipping. It hopefully just crashes. For the bootup logo, there is protection so that blitting does not happen as the image is drawn further and further to the right (ROTATE_UR) or further and further down (ROTATE_CW). There is however no protection when drawing in the opposite directions (ROTATE_UD and ROTATE_CCW). Add back this protection. The regression is 20-odd years old but the mindless warning-killing mentality displayed in commit 34bdb666f4b2 ("fbdev: fbmem: remove positive test on unsigned values") is also to blame, methinks.

2019-02-12MLK-20223 video: epdc: Increase the time available for LUT cleanupBogdan Chircu
The problem is that the kthread from submit workqueue aquires the queue_mutex and blocks the kthread from interrupt workqueue. But the kthread from interrupt workqueue is the one that should update the used_luts variable (on which the kthread from submit workqueue keeps polling), but it doesn't have a chance to do it (because it is blocked by mutex), even if the LUT complete interrupts are triggered. So the fix is, after the polling to release the mutex so that the kthread from interrupt workqueue can process the LUT complete interrupts and update the used_luts variable accordingly.

2019-02-12MLK-18585 video: fb: sii902x: Only bind to first mxs-lcdif FBLeonard Crestez
This driver registers itself as a fb_client and handles notifications from all FB in the system. It can end up trying to call fb_draw_logo on an overlay FB and this will crash because overlay_fb_ops has no fb_imageblit function. It also handles blank/unblank indiscriminately and for example if you connect a second LVDS display on 6sx and blank/unblank it then HDMI will also incorrectly blank/unblank. This last issue even affects imx_4.9.y Fix by only processing notifications from the FB that it's bound to. Bind to the first FB whose name starts with "mxs-lcdif" by checking fb_info->fix.id on FB_EVENT_FB_REGISTERED.
