On SDM845 DSI needs to express a perforamnce state
requirement on a power domain depending on the clock rates.
Use OPP table from DT to register with OPP framework and use
dev_pm_opp_set_rate() to set the clk/perf state.

driver.
This will need correcting so I will send out a second version and respond
to Sam Ravnborg's feedback at the same time. I recommend waiting for that
version before reviewing as this will not function on

Hi Sam,
Thanks for giving feedback. When I send out v2 I'll CC you on the rest of the
series
to be sure you have visibility. My responses are below.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

4cc is more generic than pixel format.

Some memory is vmalloc'ed in the 'suspend' function and freed in the
'resume' function.
However, it is also freed in the remove function.
In order to avoid a potential double free, set the corresponding pointer
to NULL once freed in the 'resume' function.

Do note that ath11k patches go to my ath.git tree, not net-next. But no
need to resend because of this.

I find it safer to handle also such source code adjustments
by a small patch series together with improved commit messages.

Add dt-bindings for Synopsys DesignWare MIPI DSI Host and VPG (Video
Pattern Generator) support in the IPK display subsystem.
The Synopsys DesignWare IPK display video pipeline is composed by a DSI
controller (snps,dw-ipk-dsi) and a VPG (snps,dw-ipk-vpg) as DPI
stimulus. Typically is used the

The struct member 'asic_setup' was assigned twice, let's remove one:
