The current keep-alive check mechanism uses a static variable that is
initialized to 0. When the function is first called, it may happen to
catch the 8-bit keep-alive counter right when it overflows, hence
returning BUSY.This patch will keep checking the counter for 10us, every 1us, but it
will immediately return if the keep-alive counter changed.Signed-off-by: Laurentiu Palcu

Update the HX8363 mipi panel to use new mipi dsi bridge interfaces
to register a panel device and send command packets. So this panel
driver can decouple with mipi_dsi_northwest driver.A new header file mipi_dsi_panel.h is added for all panel init
functions declare.Signed-off-by: Ye Li

Update the mipi_dsi_northwest driver to implement mipi dsi bridge interfaces
and register it as a bridge controller. Users can call bridge common interfaces

it to DSI host driver and then enable the DSI host.Signed-off-by: Ye Li

Add the host driver base from kernel for MIPI DSI controller on i.MX7ULP.
The controller provides a DPI-2 interface for LCDIF video stream, and a APB interface
for packet transmission.The driver provides APIs to register a MIPI panel device and its driver. The panel
driver can use the write packet function provided by the host driver to send control
packets to panel device via APB interface.MIPI DSI has its PHY and dedicated PLL. The driver will setup them when enabling the DSI
host.Signed-off-by: Ye Li

Support EPDC.
E-Ink feature is supported by i.MX6DL/SL/SLL/ULL and i.MX7D.This driver supports user defined logo file, if there is no logo file, it will
draw a black border around a white screen.If need to enable EPDC, a waveform file is required to let all
work.Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME
support.Please refer to Linux Reference Manual for how to flash WAVEFORM file.

This migrates rk_vop (the shared functions used by multiple VOP
mini-drivers) to be compatible with a live tree.Unfortunately, there's
(i) a lot of tree traversal needed for a VOP (as each active VOP
vnode references back to the endpoints in the encoders and vice
versa) to configure the connection between VOPs and encoders;
(ii) the DTS binding is not too sane and one needs to walk a node's
parents (the original code just assumed that the device would
live 3 levels above the property linked through a phandle) until
a UCLASS_DISPLAY device can be found.As part of the migration, the code for finding the enclosing display
device has been changed to not assume a specific depth of nesting
(i.e. we walk until we reach the root or find a matching device) and
to use the newly introduced (in the same series) ofnode_get_parent()
function.Signed-off-by: Philipp Tomsich

The rk_hdmi (shared functions for multiple HDMI mini-drivers) has been
using devfdt_get_addr() to read the HDMI controller's IO base address.
This will cause a failure with a live tree.This changes the driver to use dev_read_addr() which is safe both for
flat trees and live trees.Signed-off-by: Philipp Tomsich
