| * CSR (control and status registers) |
| * |
| * CSR registers are mapped directly into PCI bus space, and are accessible |
| * whenever platform supplies power to device, even when device is in |
| * low power states due to driver-invoked device resets |
| * (e.g. CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes. |
| * |
| * Use iwl_write32() and iwl_read32() family to access these registers; |
| * these provide simple PCI bus access, without waking up the MAC. |
| * Do not use iwl_write_direct32() family for these registers; |
| * no need to "grab nic access" via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ. |
| * The MAC (uCode processor, etc.) does not need to be powered up for accessing |
| * the CSR registers. |
| * |
| * NOTE: Device does need to be awake in order to read this memory |
| * via CSR_EEPROM and CSR_OTP registers |
