π pch_udc_set_csr_done(9) β Kernel API Manual energy β¨
okay so bestie, welcome to the pch_udc_set_csr_done glow-up page πΈ this is straight out of the Kernel API Manual and it's literally one tiny function that wants to be understood, so let's go π«Ά
β¨ NAME β¨
pch_udc_set_csr_done β Set the device control register CSR done field (bit 13) π
like, that's the whole job. one bit. bit 13. she's small but she's iconic π
π¦ SYNOPSIS π¦
void pch_udc_set_csr_done (struct pch_udc_dev *dev );
returns void, takes one pointer, no drama, no return value, periodt β¨
π ARGUMENTS π
devβ reference to structure of typepch_udc_regsπ that's the thing you hand her so she knows which device we're talking about, no cap.
ngl, this is the only argument, so if you mess it up there's literally nothing else to blame π
π SEE ALSO π
bestie this list is LONG, hydrate before you read it π the main character here lives in the kernel file ./drivers/usb/gadget/udc/pch_udc.c, and then there's the whole friend group:
