Hi Marek,
Thank you for the patch.
On lun., juin 17, 2024 at 19:36, Marek Vasut marek.vasut+renesas@mailbox.org wrote:
Extend generic_setup_phy() parameter list with PHY mode and submode and call generic_phy_set_mode() in generic_setup_phy(), so the generic PHY setup function can configure the PHY into correct mode before powering the PHY up.
Update all call sites of generic_setup_phy() as well, all of which are USB host related, except for DM test which now behaves as a USB host test.
Note that if the PHY driver does not implement the .set_mode callback, generic_phy_set_mode() call returns 0 and does not error out, so this should not break any existing systems.
