[PATCH 5.10 070/226] media: venus: core: Add io base variables for each block

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx>

[ Upstream commit b4053a2097ec2f8ea622e817ae5a46a83b23aefe ]

New silicon means that the pre-determined offsets we have been using
in this driver no longer hold. Existing blocks of registers can exist at
different offsets relative to the IO base address.

This commit adds a routine to assign the IO base hooks a subsequent commit
will convert from absolute to relative addressing.
