2019-02-12MLK-14857: mxc_hdmi: Set default mode a CEA modeRobert Chiras
When using fb_find_mode from fbdev/core with a specified user more, it will return a screeninfo structure with the pixclock corresponding to a different refresh rate than the requested one. For example, for 1920x1080@60 it will return pixclock=5780. When we get the videmode for this screeninfo, it will have a refresh of 59Hz, instead of 60Hz. If we use this mode as default mode when EDID cannot be read, on a monitor with fixed refresh rate of 60Hz, it won't work. Therefore, we should save the default mode, the nearest mode from CEA modes defined by our own driver (which will have the correct refresh rate and pixclock for the requested resolution).

commit 70f2d20917bc ("MLK-14884 mmc: sdhci: make DDR50 tuning optionally") want to make DDR50 card tuning optionally, but the code logic is not right, the tuning of DDR50 card will also be impacted by the flag 'SDHCI_SDR50_NEEDS_TUNING'. e.g. imx6sl/imx6sx/imx6ul/imx7d default set USE_TUNING_SDR50, which means on these SoC, DDR50 card still do tuning even haven't the flag 'SDHCI_DDR50_NEEDS_TUNING'. This patch fix the logic issue, separate DDR50 and SDR50 card. Signed-off-by: Haibo Chen <haibo.chen@nxp.com>

After commit 3e3274ab9ff3 ("mmc: sdhci-esdhc-imx: Use common sdhci_suspend|resume_host()"), we lost the pins state store and save in common sdhci_pltfm_{suspend|resume} API which results in the pins state lost in state un-retainable suspend/resume, then CMD transfer will meet timeout subsequently. Due to sdhci_pltfm_{suspend|resume} API becomes static after that commit later, we then do manual pins state save and restore in our platform suspend/resume API instead.

2019-02-12MLK-14648: mxc: fix default modelistRobert Chiras
When EDID read fails, the mxc_hdmi driver creates a default modelist using a hard-coded list with CEA modes. Every time the HDMI cable is plugged-in, it will destroy the current modelist and recreate the list. The problem comes from fbcon, which holds reference to current mode used for each framebuffer console. When we destroy the modelist and send the new one, if the memory for the old mode is overwritten it will try to find another mode, close to the old one. Since the mode could be overwritten by something else there is a high chance that the new selected mode to be different from the old one. If the HDMI sink does not support the selected mode, IPU will fail to deliver frames. Since it's wrong to advertise as supported modes the modes from a hard-coded list, just use one mode, which comes from cmdline. Signed-off-by: Robert Chiras <robert.chiras@nxp.com>

2019-02-12MLK-14612 media: capture: fix VIDIOC_DQBUF issuesLaurentiu Palcu
The following commit, in 4.9 kernel: commit 2d7007153f0c ("[media] media: videobuf2: Restructure vb2_buffer") added some changes to the v4l2 structures that were not properly included in the existing driver after the rebase from 4.1. Hence, when a new buffer was filled by the v4l2 core, the flags field in vb2_v4l2_buffer structure contained a pointer and, depending on the pointer value, the v4l2 core considered that the buffer was already dequeued, signaling the error to userspace. The issue appeared intermittently, after multiple reboots. This patch fixes it. Signed-off-by: Laurentiu Palcu <laurentiu.palcu@nxp.com>

2019-02-12MLK-14548: video: fb: hdmi: Allow Sil902 init regardless of fb registration timeCristina Ciocan
When a new fb is registered, a FB_EVENT_FB_REGISTERED event is sent to any registered fb client. Upon event receipt, the Sil902 HDMI transmitter saves the fb info structure address for future use and schedules a cable state check in order to setup and power up/down the device. The current Sil902 driver registers as fb client at the end of the probe function, thus events from fb core will only be received after the probe() call. If a framebuffer is registered before Sil902's probe() is called, the HDMI transmitter will not have knowledge of the framebuffer. This patch moves the Sil902 fb client registration step into an __init function and saves the fb info in case any registration event is received prior to the probe() call. When the probe() is called, check for any registration event and act accordingly. Sil902's init function class is called after the frame buffer core's init function class.
