66 * CSR (control and status registers)
67 *
68 * CSR registers are mapped directly into PCI bus space, and are accessible
69 * whenever platform supplies power to device, even when device is in
70 * low power states due to driver-invoked device resets
71 * (e.g. CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes.
72 *
73 * Use iwl_write32() and iwl_read32() family to access these registers;
74 * these provide simple PCI bus access, without waking up the MAC.
75 * Do not use iwl_write_direct32() family for these registers;
76 * no need to "grab nic access" via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ.
77 * The MAC (uCode processor, etc.) does not need to be powered up for accessing
78 * the CSR registers.
79 *
80 * NOTE:  Device does need to be awake in order to read this memory
81 *        via CSR_EEPROM and CSR_OTP registers

341 *                MAC_SLEEP is the best indication that restore is complete.
342 *                Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and
343 *                do not need to save/restore it.
