* ENGR00323172 EPDC: there will be garbage when doing rotation unit testFancy Fang2014-07-17
| | | | | | | | Just as what the V4L2 PXP does, we should pass the drect w/h and output w/h accroding to the rotation angle. Signed-off-by: Fancy Fang <chen.fang@freescale.com> (cherry picked from commit bf95e3ee4131ce3ee78050f098704588766e8b07)
* ENGR00321817-01 HDMI: Dispaly blank after resumeSandor Yu2014-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue reproduce steps: 1. Boot up without HDMI cable plugin 2. Insert the HDMI cable. 3. echo mem > /sys/power/state , enter suspend, 4. resume it, System can resume from suspend but display is blank. Error log: mxc_sdc_fb fb.31: Unable to allocate framebuffer memory detected fb_set_par error, error code: -12 In mxc hdmi driver, if system bootup without hdmi cable plugin, driver will create a default modelist. In fbcon driver, array fb_display[] initialized when system bootup and save current mode pointer that point to default modelist. When hdmi cable is plugin the modelist will rebuild according edid data, but the pointer of video mode in fb_display[] is not updated. When system resume, fbcon will use the invalidate pointer to configured framebuffer, framebuffer will crash. Add function fb_new_modelist() after modelist is rebuild to fix the issue.

* ENGR00322272-2: video: mxc ldb: remove ldb_di_sel from pixel rate setupShawn Guo2014-07-11
| | | | | | | | | | | | | | | | | Since commit 0bec46131d88 (ENGR00318063-8: ARM: imx6q: hide buggy ldb_di_sel from clk API), the mux clock ldb_di_sel becomes unavailable from the clock tree. The LDB driver sets up its pixel clock rate with the help of ldb_di_sel knowledge, and thus causes problem. The net result is the LDB pixel clock rate slows down to 50 MHz (50285714) from the original 64 MHz (64653061) on imx6q. The patch fixes the problem by removing the ldb_di_sel knowledge from the clock configuration path and just setting the rate on div_sel[chno] clock. The bonus point is that we can use chan.vm.pixelclock directly instead of calculating the required rate we need to set on ldb_di_sel_parent. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

* ENGR00306875-2 video: mxc_hdmi: Set hdmi cable state a bit earilierNicolin Chen2014-04-16
| | | | | | | | | | | | | | | | | During hdmi hotplug test, there's a possibility that X-server unblanks the frame buffer while HDMI-audio just gets the signal to start playback. Then audio would get an unblanked state right before the playback and bypassed the DMA enabling code. So this issue is caused by the race between unblank and set_cable_state(). This patch sets the hdmi cable state a bit earilier so as to let audio play first. If unblank happens later, the hdmi core and hdmi audio would be robust enough to handle that case as long as it's not racing with the other parts.

* ENGR00305369 video: mxc ldb: disable channel in setup callbackLiu Ying2014-04-16
| | | | | | | | | | In order to avoid any pixelation issue, we should disable a LVDS channel before its relevant display controlled is enabled. This patch adds logics to disable the LVDS channel in the setup() callback which is invoked before the IPUv3 display controller is disabled and re-enabled.

Fixed: - Remove unused previous_mode - Add default_mode, initialize in disp_init function. - Initialize fbi->mode in disp_init function and hdmi_setup function.

* ENGR00302472-6 video: mxc: LDB driver refactorLiu Ying2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | This patch almost reworks the LDB driver to make the implementation simpler and clearer. The new version should support all the LDB modules embedded in imx53, imx6qdl and imx6sx. The lvds-channel subsidiary DT node is introduced to represent each LVDS channel. People may specify a channel's CRTC, working mode(dual mode or split mode), data width, data mapping, display timing and if it is a primary channel in the node. Change logs: * Use CTRC concept so that the driver may support both IPU and LCDIF as the display engines. * Add mxc dispdrv enable() callback. * Cache LDB ctrl register value at probe()/setup()/ enable() stages and finally write to the register at enable() stage. * Simplify logics for setting ctrl/bus muxing/clocks. * Use regmap to write crtl and bus muxing registers. * Remove LDB description in DT binding doc fsl_ipuv3_fb.txt. Instead, add a new one in fsl,ldb.txt. Signed-off-by: Liu Ying <Ying.Liu@freescale.com>
* ENGR00302472-5 video: mxc disp: Let encoder know fbi when enable/disableLiu Ying2014-04-16
| | | | | | | | | | | This patch adds framebuffer info structure to the mxc display driver enable/disable callback parameters so that the encoder drivers may know the framebuffer information. In this way, the encoder drivers which may deal with more than one framebuffer are able to figure out the one it is handling. A real example is the LDB encoder, which may deal with two standalone framebuffers at most. Signed-off-by: Liu Ying <Ying.Liu@freescale.com>
* ENGR00302472-4 video: mxc ipuv3 fb: Don't bail out if no DT mode strLiu Ying2014-04-16

* ENGR00302472-3 video: mxc: Introduce CRTC conceptLiu Ying2014-04-16
| | | | | | | | | | | As the mxc display system is getting more and more complex, various CRTCs(CRT controllers), such as IPUx DIy and LCDIFz, may drive various encoders. For example, imx6sx/imx6dl LCDIF may drive LDB while imx6dl IPU0 DI0/1 may drive LDB as well. This patch introduces CRTC concept to the display framework so that the core logic could be less IPU specific. Signed-off-by: Liu Ying <Ying.Liu@freescale.com>
* ENGR00299600 hdmi:yocto gui can not show to some TV on ard boardSandor Yu2014-04-16
| | | | | | | | | | | | | | | | For i.MX6 ARD board, the board not support read EDID from TV, so HDMI driver will create a default support mode list when system bootup. Because yocto xserver can not get video mode information from framebuffer now, and xserver will set default video mode XGA to framebuffer, but XGA mode is not support by hdmi. Remove XGA and SXGA from default support list. HDMI driver will find a nearest match video mode in support list. It is VGA mode. HDMI support VGA mode well. Issue is fixed.

* ENGR00286462 mx6sl fb: fix runtime pm not work at probe timeRobby Cai2014-04-16
| | | | | | | | | | | | | | For mxsfb, the lcdif controller is enabled (with clock enabled as well) at probe time, but pm_runtime_enable() is called after its enablement, thus runtime pm function only works at next enablement. The root cause is that pm_runtime_get_sync() function need to be called after pm_runtime_enable(). This patch fixes the problem by moving the position of pm_runtime_enable() ahead. For epdc fb, runtime pm may not work at probe time if DEFAULT_PANEL_HW_INIT is turned on (off by default). Fix it for safety. Signed-off-by: Robby Cai <R63905@freescale.com>
