Shared boost allows two amplifiers to share a single boost circuit bycommunicating on the MDSYNC bus. The passive amplifier does not controlthe boost and receives data from the active amplifier. GPIO1 should beconfigured for Sync when shared boost is used. Shared boost is notcompatible with External boost. Active amplifier requiresboost-peak-milliamp, boost-ind-nanohenry and boost-cap-microfarad. 0 = Internal Boost 1 = External Boost2 = ReservedHow binding can be reserved? For what and why? Drop. 2 is shared active, 3 is shared passive.
2 Is shared boost without VSPK switch, a mode not supported for new system designs. But there is laptops using it, so we need to keep supporting in the driver.
That's not the answer. 2 is nothing here, so it cannot be reserved. Aren't you mixing now some register value with bindings?
Best regards, Krzysztof
I have added a new patch with propper documentation. And I would like to use 3 and 4 for shared boost as CS35L41_EXT_BOOST_NO_VSPK_SWITCH already exist as 2 and is used in the current driver. The laptop that uses CS35L41_EXT_BOOST_NO_VSPK_SWITCH doesn't have the property "cirrus,boost-type", but to make everything consistent I would prefer to use 3 and 4 for the new boost types. Is that ok with you?
Thanks Lucas
