Always stash the address error_entry() is going to return to, in %r12
and get rid of the void *error_entry_ret; slot in struct bad_iret_stack
which was supposed to account for it and pt_regs pushed on the stack.
After this, both fixup_bad_iret() and sync_regs() can work on a struct
pt_regs pointer directly.

Whenever pclk_vo is enabled hclk_vo must be enabled as well. This is
described in the Reference Manual as:
| 2.8.6 NIU Clock gating reliance
|
| A part of niu clocks have a dependence on another niu clock in order to
| sharing the internal bus. When these clocks are in use, another niu
| clock must be opened, and cannot be gated. These clocks and the special
| clock on which they are relied are as following:
|
| Clocks which have dependency The clock which can not be gated
| -----------------------------------------------------------------
| ...
| pclk_vo_niu, hclk_vo_s_niu hclk_vo_niu
| ...
The clock framework doesn't offer a way to enable clock B whenever clock A is
enabled, at least not when B is not an ancestor of A. Workaround this by
marking hclk_vo as critical so it is never disabled. This is suboptimal in
terms of power consumption, but a stop gap solution until the clock framework
has a way to deal with this.
We have this clock tree:
| aclk_vo 2 2 0 300000000 0 0 50000 Y
| aclk_hdcp 0 0 0 300000000 0 0 50000 N
| pclk_vo 2 3 0 75000000 0 0 50000 Y
| pclk_edp_ctrl 0 0 0 75000000 0 0 50000 N
| pclk_dsitx_1 0 0 0 75000000 0 0 50000 N
| pclk_dsitx_0 1 2 0 75000000 0 0 50000 Y
| pclk_hdmi_host 1 2 0 75000000 0 0 50000 Y
| pclk_hdcp 0 0 0 75000000 0 0 50000 N
| hclk_vo 2 5 0 150000000 0 0 50000 Y
| hclk_hdcp 0 0 0 150000000 0 0 50000 N
| hclk_vop 0 2 0 150000000 0 0 50000 N
Without this patch the edp, dsitx, hdmi and hdcp driver would enable their
clocks which then enables pclk_vo, but hclk_vo stays disabled and register
accesses just hang. hclk_vo is enabled by the VOP2 driver, so reproducibility
of this issue depends on the probe order.

In xemaclite_open() function we are setting the max speed of
emaclite to 100Mb using phy_set_max_speed() function so,
there is no need to write the advertising registers to stop
giga-bit speed and the phy_start() function starts the
auto-negotiation so, there is no need to handle it separately
using advertising registers. Remove the phy_read and phy_write
of advertising registers in xemaclite_open() function.

Unlike on R-Car Gen3 SoCs, setting a bit to zero in a GPIO / Peripheral
Function Select Register (GPSRn) on R-Car S4-8 is not always sufficient
to configure a pin for GPIO. For I2C-capable pins, the I2C function
must also be explicitly disabled in the corresponding Module Select
Register (MODSELn).
Add the missing FN_SEL_I2Ci_0 function enums to the pinmux_data[] array
by temporarily overriding the GP_1_j_FN function enum to expand to two
enums: the original GP_1_j_FN enum to configure the GPSR register bits,

Some ChromeOS EC devices (such as the Framework Laptop) only map I/O
ports 0x800-0x807. Making the larger reservation required by the non-MEC
LPC (the 0xFF ports for the memory map, and the 0xFF ports for the
parameter region) is non-viable on these devices.
Since we probe the MEC EC first, we can get away with a smaller
reservation that covers the MEC EC ports. If we fall back to classic
LPC, we can grow the reservation to cover the memory map and the
parameter region.
cros_ec_lpc_probe also interacted with I/O ports 0x800-0x807 without a
reservation. Restructuring the code to request the MEC LPC region first
obviates the need to do so.

DPK is short for digital pre-distortion calibration. It can adjusts digital
waveform according to PA linear characteristics dynamically to enhance
TX EVM.
Do this calibration when we are going to run on AP channel. To prevent
power offset out of boundary, it monitors thermal and set proper boundary
to register.
8852c needs two backup buffers, so we enlarge the array. But, 8852a still
needs only one, so it only uses first element (index zero).

IQ signal calibration is a very important calibration to yield good RF
performance. We do this calibration only if we are going to run on AP
channel. During scanning phase, without this calibration RF performance
is still acceptable because it transmits with low data rate at this phase.

TSSI is transmitter signal strength indication, which is a close-loop
hardware circuit to feedback actual transmitting power as a reference for
next transmission.
When we setup channel to connect an AP, it does full calibration. When
switching bands or channels, it needs to reset hardware status to prevent
use wrong feedback of previous transmission.
To do TX power compensation reflecting current temperature, it loads tables
of compensation values into registers according to channel and band group.
