Different queue can have different behavior. While it can be
unacceptable for a certain queue to be stuck for 2 seconds
(e.g. the command queue), it can happen that another queue
will stay stuck for even longer (a queue servicing a power
saving client in GO).
The op_mode can even make the timeout be a function of the

The allocation of the DCCM between the data and the stack
can theoretically change without notice to the driver, but
the total size is HW-fixed. Since the stack CCM (runtime
stack) has also data important to the FW - this patch allows
pulling the whole DCCM in one piece and adds it to the dump
data.

If the size isn't known - just use the data part of the
DCCM as it appears in the FW TLVs.

Fix a bug in nvm_read_section function if size of the section
is a multiple of 2K:

   - if the size of the section is *not* multiple of 2K,
   then we will have: read(2K) - return 2K ... read(2K) - return 2K
   read(2K) - return the rest (in bytes) and exit the while loop.
   - else, if the size of the section is a multiple of 2K,
   then we have: read(2K) - return 2K read(2K) - return 2K read(2K) -
   return 2K read(2K) - return 0 and exit the while with an error.

We should not return an error in the latter case, because it

A hardware bug had been discovered on 7260 / 3160 and 7265
and the workaround for this bug is to force the NIC to stay
awake as long as we have host commands in flight. This
workaround has been introduced for all NICs in a previous
patch:

b9439491 ("iwlwifi: pcie: keep the NIC awake when commands are in flight")

In newer NICs, this bug is solved, so we can let the NIC go
to sleep even when we send commands. The hardware will wake
up when we increment the scheduler write pointer.
Make the workaround conditional to only use it on affected
hardware.

1. Enable LP XTAL to avoid HW bug where device may consume much
power if FW is not loaded after device reset. LP XTAL is
disabled by default after device HW reset. Configure device's
"persistence" mode to avoid resetting XTAL again when SHRD_HW_RST
occurs in S3.

2. Add methods to access SHR (shared block memory space) directly from PCI
bus w/o need to power up MAC HW.

Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be
accessed directly from PCI bus through SHR arbiter even when MAC HW is
powered down. This is possible due to indirect read/write via
HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4)
registers.

Use iwl_write32()/iwl_read32() family to access these registers. The MAC HW
need not be powered up so no "grab inc access" is required.

For example, to read from SHR_APMG_GP1 register (0x1DC),
first, write to the control register:
HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register)
HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 2 (read access)
second, read from the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0].

To write the register, first, write to the data register
HEEP_CTRL_WRD_PCIEX_DATA[31:0] and then:
HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register)
HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 3 (write access)

D0i3 is bus power saving feature. It involves the
firmware - the driver needs to send a list of commands
to the firmware before entering this state. Wake up from
d0i3 also requires a few commands to the firmware.

The trigger to enter D0i3 is an idle timeout that will be
implemented later and will most probably rely on RUNTIME_PM
infrastructure.

In order to prevent entrance to D0i3 in critical flows, we
implement here a reference infrastructure. When a ref is
taken, we can't enter D0i3.

PCIe does't support D0i3.

The tx backoff settings used by the thermal throttling mechanism can
also be used for enforcing a limit on the power consumption of the module.

Handle the platform PCIe power limitation by translating the limit
(measured in mw) to its respective tx backoff value. The translation is
module specific.

The resulting tx backoff value is sent to the ucode, and also serves as the
minimal backoff value that can be set by the thermal throttling mechanism.
