Problem:
Hdmitx is a notify server, it should
notify hpd event unconditionally.
For clients which want to know hpd/edid
change of hdmitx side, need to register
notify callback of hdmitx server.
For clients which don't want to know
hpd/edid change of hdmitx side, it
should not register notify callback of
hdmitx server, or it register notify
callback but ignore HPD/EDID info
Solution:
always notify hpd event to clients unconditionally

This patch is to prevent printing annoying kernel log '...could not find
display-timings node...' when a device tree does not contain the node.
drivers/video/of_display_timing.c:
struct display_timings *of_get_display_timings(const struct device_node *np)
{
...
timings_np = of_get_child_by_name(np, "display-timings");
if (!timings_np) {
pr_err("%pOF: could not find display-timings node\n", np);
return NULL;
}
}

This patch is to set the default display mode within probed display
modes by given kernel parameter as
aml_drm.displaymode=<MODENAME>[:force]
where, MODENAME is the name of display mode and optionally ':force' can
be added in order to ignore the rest display modes so one display mode
is present in the system.

This patch is to add HDMI custom video timing and enforce the use of it no
matter whether EDID from the HDMI display is provided or not.
The custom video mode must be passed via Linux kernel command line in
the form of this;
aml_drm.modeline=<NAME>,<PCLK>,<H-TIMING>,<V-TIMING>[,HSYNC][,VSYNC][,SCANMODE]
where,
NAME : the video timing name and must not contain 'space'
PCLK : the pixel clock in MHz
H-TIMING : the horizontal video timing
<h-width>,<h-sync-start>,<h-sync-end>,<h-total>
V-TIMING : the vertical video timing
<v-widtv>,<v-sync-start>,<v-sync-end>,<v-total>
HSYNC/VSYNC : polarity of H-Sync and V-Sync,
* +HSync
* -HSync (default)
* +VSync
* -VSync (default)
SCANMODE : video scan mode string
* Progressive (default)
* Interlaced
HSYNC/VSYNC/SCANMODE are not case sensitive and the default value will
be applied when omitted

This patch adds to Wake On Lan with an extern ethernet phy and the wake
up is triggered through a GPIO pin. GPIOH_10 on ODROID-C5 is connected
to #INT of RTL8211F.
The method to enable WOL in generic Linux:
$ sudo ethtool -s eth0 wol ug
$ sudo systemctl suspend
The Amlogic's method is:
$ echo 1 | sudo tee /sys/class/ethernet/wol
$ sudo systemctl suspend

vdin1 node is removed in this commit :
[fb2690f09 ODROID-C5: arm64/dts: Removed unused nodes.]
However, this node is required to support screen capture using
/dev/video12 node which is related with amlvideo2 driver.
Without this, driver couldn't acquire the memory space to store frame data,
and it returns EBUSY error when VIDIOC_STREAMON is performed by ioctl.

We fixed this properties to make android 4K UI.
ro.surface_flinger.max_graphics_width=3840
ro.surface_flinger.max_graphics_height=2160
It causes an error.
aml_cma_alloc: heap-fb: alloc failed, req-size: 8227 pages, ret: -12
Increasing the size of dmaheap_fb_reserved by 2x will solve error.
