[PATCH 6.5 454/491] media: qcom: camss: Fix set CSI2_RX_CFG1_VC_MODE when VC is greater than 3

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

 



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

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

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

commit e655d1ae9703286cef7fda8675cad62f649dc183 upstream.

VC_MODE = 0 implies a two bit VC address.
VC_MODE = 1 is required for VCs with a larger address than two bits.

Fixes: eebe6d00e9bf ("media: camss: Add support for CSID hardware version Titan 170")
