Pull TDA998x i2c driver fixes from Russell King:
"This fixes the double-checksumming of the AVI infoframe which was
resulting in the checksum always being zero. It went unnoticed as
none of my HDMI devices had a problem with this"

drm/i2c: tda998x: fix bad checksum of the HDMI AVI infoframe
|
|
The commit 8c7a075da9f7980cc95ffcd7e6621d4a87f20f40
"drm/i2c: tda998x: use drm_hdmi_avi_infoframe_from_display_mode()"
also uses hdmi_avi_infoframe_pack() to create the AVI infoframe.
This function sets the checksum of the frame and this breaks
the second calculation of the checksum done in tda998x_write_if().

Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.
This also updates all the clients of multi_reg_write/register_patch.

The ADV7511 is probed before its slave encoder init function associates
it with an encoder. This creates a time window during which hot plug
detection interrupts can occur with an encoder, resulting in a crash in
the IRQ handler.
Fix this by ignoring hot plug detection IRQs when no encoder is
associated yet.

Remove the internal dependency on DPMS mode for power management by
using a by a powered state boolean instead, and use the new power off
handler at probe time. This ensure that the regmap cache is properly
marked as dirty when the device is probed, and the registers properly
synced during the first power up.
As a side effect this removes the initialization of current_edid_segment
at probe time, as the field will be initialized when the device is
powered on, at the latest right before reading EDID data.

The EDID read code waits for the read completion interrupt to occur
using wait_event_interruptible(). The condition passed to the macro
reads I2C registers. This results in sleeping with the task state set
to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit
8eb23b9f35aae ("sched: Debug nested sleeps").
Fix this by reworking the EDID read code. Instead of checking whether
the read is complete through I2C reads, handle the interrupt registers
in the interrupt handler and update a new edid_read flag accordingly. As
a side effect both the IRQ and polling code paths now process the
interrupt sources through the same code path, simplifying the code.

Add component helper support to the tda998x driver. This permits the
TDA998x to be declared as a separate device in device tree, and bound
at the appropriate moment with a co-operating card driver.

users of it in order to prevent regressions.

Re-jig the TDA998x code so that we separate the functionality from the
drm slave encoder implementation. In several places, this is pretty
clearly the correct thing to do, because we can avoid repetitively
having to convert from the drm_encoder to the TDA998x private
structure, particularly with the driver internal functions.
The main motivation behind this change is to allow the code to be
re-used with a standard drm_encoder and drm_connector implementation
based on the component helpers, rather than the slave_encoder system.
The addition of this will be in the following patch.
We keep the slave_encoder interface as there are existing users of
this; we need to give them time to convert and test.

Currently tda998x_encoder_destroy() calls cec_write() and reg_clear(),
as part of the release procedure. Such calls need to access the I2C bus
and therefore, we need to call them before drm_i2c_encoder_destroy()
which unregisters the I2C device.
This commit moves the latter so it's done afterwards.

This is C standard hair-splitting, but afaict
- sum will be promoted to signed int in computation since
uint8_t fits
- signed overflow is undefined.
No we need to add up an awful lot of bytes to actually make it
overflow. But I guess the real risk is gcc spotting this and going
bananas. Fix this by simply using unsigned in to force all computations
to use the well-defined unsigned behaviour.
Spotted by coverity.
v2: Simplify the entire computation as suggested by Jean.
