drm/rockchip: lvds: Change platform data to hold helper_funcs pointer
Prepare the introduction of PX30 support by using
drm_encoder_helper_funcs as platform data instead of multiple register
names which are specific to rk3288 and not generic to all Rockchip
IPs. This way adding support for a new flavor of a similar IP will be
a matter of adding the relevant helper funcs.

When configuring the frame memory window, the last column and row

numbers are thus one less than the actual window width resp. height.
While this is handled correctly in mipi_dbi_fb_dirty() since commit

drm/sun4i: dsi: Handle bus clock via regmap_mmio_attach_clk
regmap has special API to enable the controller bus clock while
initializing register space, and current driver is using
devm_regmap_init_mmio_clk which require to specify bus
clk_id argument as "bus"
But, the usage of clocks are varies between different Allwinner
DSI controllers. Clocking in A33 would need bus and mod clocks
where as A64 would need only bus clock.
Since A64 support only single bus clock, it is optional to
specify the clock-names on the controller device tree node.
So using NULL on clk_id would get the attached clock.
To support clk_id as "bus" and "NULL" during clock enablement
between controllers, this patch add generic code to handle
the bus clock using regmap_mmio_attach_clk with associated
regmap APIs.

udmabuf: fix dma-buf cpu access
I'm just going to put Chia's review comment here since it sums
the issue rather nicely:
"(1) Semantically, a dma-buf is in DMA domain. CPU access from the
importer must be surrounded by {begin,end}_cpu_access. This gives the
exporter a chance to move the buffer to the CPU domain temporarily.
(2) When the exporter itself has other means to do CPU access, it is
only reasonable for the exporter to move the buffer to the CPU domain
before access, and to the DMA domain after access. The exporter can
potentially reuse {begin,end}_cpu_access for that purpose.
Because of (1), udmabuf does need to implement the
{begin,end}_cpu_access hooks. But "begin" should mean
dma_sync_sg_for_cpu and "end" should mean dma_sync_sg_for_device.
Because of (2), if userspace wants to continuing accessing through the
memfd mapping, it should call udmabuf's {begin,end}_cpu_access to
avoid cache issues."

- Calculate the packet sizes in bytes as in the vendor driver,

- Handle negative result in front/back/sync packages and fall

drm/drm_panel: Fix EXPORT of drm_panel_of_backlight() one more time
The initial commit followed by the fix didn't
take into consideration the case:
CONFIG_DRM_PANEL=y
CONFIG_BACKLIGHT_CLASS_DEVICE=m
CONFIG_DRM_I915=y
where symbol devm_of_find_backlight() is not reachable from DRM subsystem.
Quick fix is to avoid drm_panel_of_backlight() from exporting in such case.

drm/print: introduce new struct drm_device based logging macros
Add new struct drm_device based logging macros modeled after the core
kernel device based logging macros. These would be preferred over the
drm printk and struct device based macros in drm code, where possible.
We have existing drm specific struct device based logging functions, but
they are too verbose to use for two main reasons:
* The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS().
* The use of struct device over struct drm_device is too generic for
most users, leading to an extra dereference.
For example:
DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n");
vs.
drm_dbg_kms(drm, "Hello, world\n");
It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be
less readable than lowercase.
Some names are changed from old DRM names to be based on the core kernel
logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG ->
dbg.
Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use
(DRM_DEBUG is used widely in drivers though it's supposed to be a core
debugging category), they are named as drm_dbg_core and drm_dbg,
respectively.
The drm_err and _once/_ratelimited variants no longer include the
function name in order to be able to use the core device based logging
macros. Arguably this is not a significant change; error messages should
not be so common to be only distinguishable by the function name.
Ratelimited debug logging macros are to be added later.

drm/modes: parse_cmdline: Make various char pointers const
We are not supposed to modify the passed in string, make char pointers
used in drm_mode_parse_cmdline_options() const char * where possible.

drm/modes: parse_cmdline: Fix possible reference past end of string
Before this commit, if the last option of a video=... option is for
example "rotate" without a "=<value>" after it then delim will point to
the terminating 0 of the string, and value which is sets to <delim + 1>
will point one position past the end of the string.
This commit fixes this by enforcing that the contents of delim equals '='
as it should be for options which take a value, this check is done in a
new drm_mode_parse_cmdline_int helper function which factors out the
common integer parsing code for all the options which take an int.

drm/rockchip: add ability to handle external dphys in mipi-dsi
While the common case is that the dsi controller uses an internal dphy,
accessed through the phy registers inside the dsi controller, there is
also the possibility to use a separate dphy from a different vendor.
One such case is the Rockchip px30 that uses a Innosilicon Mipi dphy,
so add the support for handling such a constellation, including the pll
also getting generated inside that external phy.

Some dw-mipi-dsi instances in Rockchip SoCs use external dphys.
In these cases the needs clock will also be generated externally

drm/bridge/synopsys: dsi: move phy_ops callbacks around panel enablement
If implementation-specific phy_ops need to be defined they probably
should be enabled before trying to talk to the panel and disabled only
after the panel was disabled.
Right now they are enabled last and disabled first, so might make it
impossible to talk to some panels - example for this being the px30
with an external Innosilicon dphy that needs the phy to be enabled
to transfer commands to the panel.
So move the calls appropriately.
