DRM bridge drivers are now attaching their DSI device at probe time,
which requires us to register our DSI host in order to let the bridge
to probe: this recently started producing an endless -EPROBE_DEFER
loop on some machines that are using external bridges, like the
parade-ps8640, found on the ACER Chromebook R13.
Now that the DSI hosts/devices probe sequence is documented, we can
do adjustments to the mtk_dsi driver as to both fix now and make sure
to avoid this situation in the future: for this, following what is
documented in drm_bridge.c, move the mtk_dsi component_add() to the
mtk_dsi_ops.attach callback and delete it in the detach callback;
keeping in mind that we are registering a drm_bridge for our DSI,
which is only used/attached if the DSI Host is bound, it wouldn't
make sense to keep adding our bridge at probe time (as it would
be useless to have it if mtk_dsi_ops.attach() fails!), so also move
that one to the dsi host attach function (and remove it in detach).

In commit 41ca9caaae
("drm/mediatek: hdmi: Add check for CEA modes only") a check
for CEA modes was added to function mtk_hdmi_bridge_mode_valid()
in order to address possible issues on MT8167;
moreover, with commit c91026a938
("drm/mediatek: hdmi: Add optional limit on maximal HDMI mode clock")
another similar check was introduced.
Unfortunately though, at the time of writing, MT8173 does not provide
any mtk_hdmi_conf structure and this is crashing the kernel with NULL
pointer upon entering mtk_hdmi_bridge_mode_valid(), which happens as
soon as a HDMI cable gets plugged in.
To fix this regression, add a NULL pointer check for hdmi->conf in the
said function, restoring HDMI functionality and avoiding NULL pointer
kernel panics.

In mailbox rx_callback, it pass struct mbox_client to callback
function, but it could not map back to mtk_drm_crtc instance
because struct cmdq_client use a pointer to struct mbox_client:
struct cmdq_client {
struct mbox_client client;
struct mbox_chan *chan;
};
struct mtk_drm_crtc {
/* client instance data */
struct cmdq_client *cmdq_client;
};
so remove the pointer of struct cmdq_client and let mtk_drm_crtc
instance define cmdq_client as:
struct mtk_drm_crtc {
/* client instance data */
struct cmdq_client cmdq_client;
};
and in rx_callback function, use struct mbox_client to get
struct mtk_drm_crtc.

These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

Reset dsi0 HW to default when power on. This prevents to have different
settingis between the bootloader and the kernel.
As not all Mediatek boards have the reset consumer configured in their
board description, also is not needed on all of them, the reset is optional,
so the change is compatible with all boards.

Pull drm updates from Dave Airlie:
"Highlights:
- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward
This has all been audited with known userspace, but there may be
some pitfalls that were missed.
- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs
- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support
- amdgpu adds support for Cyan Skillfish
- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.
Otherwise the usual smattering of stuff everywhere, panels, bridges,
refactorings.
Detailed summary:
core:
- extract i915 eDP backlight into core

In mailbox rx_callback, it pass struct mbox_client to callback
function, but it could not map back to mtk_drm_crtc instance
because struct cmdq_client use a pointer to struct mbox_client:
struct cmdq_client {
struct mbox_client client;
struct mbox_chan *chan;
};
struct mtk_drm_crtc {
/* client instance data */
struct cmdq_client *cmdq_client;
};
so remove struct cmdq_client and let mtk_drm_crtc instance define
mbox_client as:
struct mtk_drm_crtc {

The orginal formula will caused rdma fifo threshold config overflow
and no one could come out a solution for all SoC,
set threshold to 70% of max fifo size to make sure it will
not overflow, and 70% is a empirical vlaue.

The field drm_device.irq_enabled is only used by legacy drivers
with userspace modesetting. Don't set it in mediatek.
