STRUCT R9A06G032_GATE(9)
π NAME π
struct r9a06g032_gate β clock-related control bits π
(yes bestie, this is from the Kernel API Manual, we're doing real kernel hours now)
β¨ SYNOPSIS β¨
struct r9a06g032_gate {
struct regbit gate, reset, ready, midle ;
};
π«Ά Members π«Ά
gateβ clock enable/disable, the whole point tbh πresetβ clock module reset, and it's active low so lowkey mind the polarity πreadyβ enables NoC forwarding of read/write requests to device, (eg. device is ready to handle read/write requests) β like it's saying "i'm up, send me stuff" fr frmidleβ request to idle the NoC interconnect, nap time for the master π΄
π Description π
So like, each of these fields describes a single bit in a register, which controls some aspect of clock gating. That's the whole vibe. π¦
The gate field is mandatory, no cap β this one enables/disables the clock, it's the main character. The other fields are optional, with zero indicating "not used" (so a zero there is literally just "ignore me" π).
In most cases there is a reset bit which needs to be de-asserted to bring the module out of reset. De-asserted, bestie, pay attention. β¨
Modules may also need to signal when they are ready to handle requests (read/writes) from the NoC interconnect β that's your ready bit doing its little job π«Ά.
Similarly, the midle bit is used to idle the master. Everybody needs a break sometimes, even the interconnect. πΈ
