Some controllers can choose to skip preparation for power up. In that case, device context is initialized based on the pre_init flag not being set during mhi_prepare_for_power_up(). There is no reason MHI host driver should maintain and provide controllers with two separate paths for preparing MHI. Going forward, all controllers will be required to call the mhi_prepare_for_power_up() API followed by their choice of sync or async power up. This allows MHI host driver to get rid of the pre_init flag and sets up a common way for all controllers to use MHI. This also helps controllers fail early on during preparation phase in some failure cases. Signed-off-by: Bhaumik Bhatt <bbhatt@xxxxxxxxxxxxxx> --- This patch was tested on arm64 architecture.
Change looks good as current MHI controllers ath11k and pci generic are not using pre_init.
