On a Chromebook I'm working on I noticed a big (~1 second) delay
during bootup where nothing was happening. Right around this big
delay there were messages about the TPM:
[ 2.311352] tpm_tis_spi spi0.0: TPM ready IRQ confirmed on attempt 2
[ 3.332790] tpm_tis_spi spi0.0: Cr50 firmware version: ...
I put a few printouts in and saw that tpm_tis_spi_init() (specifically
tpm_chip_register() in that function) was taking the lion's share of
this time, though ~115 ms of the time was in cr50_print_fw_version().
Let's make a one-line change to prefer async probe for tpm_tis_spi.
There's no reason we need to block other drivers from probing while we
load.
NOTES:
* It's possible that other hardware runs through the init sequence
faster than Cr50 and this isn't such a big problem for them.
However, even if they are faster they are still doing _some_
transfers over a SPI bus so this should benefit everyone even if to
a lesser extent.
* It's possible that there are extra delays in the code that could be
optimized out. I didn't dig since once I enabled async probe they
no longer impacted me.

The tpm2_get_cc_attrs_tbl() call will result in TPM commands being issued,
which will need the use of the internal command/response buffer. But,
we're issuing this *before* we've waited to make sure that buffer is
allocated.
This can result in intermittent failures to probe if the hypervisor / TPM
implementation doesn't respond quickly enough. I find it fails almost
every time with an 8 vcpu guest under KVM with software emulated TPM.
To fix it, just move the tpm2_get_cc_attrs_tlb() call after the
existing code to wait for initialization, which will ensure the buffer
is allocated.

During flow control we are just reading from the TPM, yet our spi_xfer
has the tx_buf and rx_buf both non-NULL which means we're requesting a
full duplex transfer.
SPI is always somewhat of a full duplex protocol anyway and in theory
the other side shouldn't really be looking at what we're sending it
during flow control, but it's still a bit ugly to be sending some
"random" data when we shouldn't.
The default tpm_tis_spi_flow_control() tries to address this by
setting 'phy->iobuf[0] = 0'. This partially avoids the problem of
sending "random" data, but since our tx_buf and rx_buf both point to
the same place I believe there is the potential of us sending the
TPM's previous byte back to it if we hit the retry loop.
Another flow control implementation, cr50_spi_flow_control(), doesn't
address this at all.
Let's clean this up and just make the tx_buf NULL before we call
flow_control(). Not only does this ensure that we're not sending any
"random" bytes but it also possibly could make the SPI controller
behave in a slightly more optimal way.
NOTE: no actual observed problems are fixed by this patch--it's was
just made based on code inspection.

It has been reported that some TIS based TPMs are giving unexpected
errors when using the O_NONBLOCK path of the TPM device. The problem
is that some TPMs don't like it when you get and then relinquish a
locality (as the tpm_try_get_ops()/tpm_put_ops() pair does) without
sending a command. This currently happens all the time in the
O_NONBLOCK write path. Fix this by moving the tpm_try_get_ops()
further down the code to after the O_NONBLOCK determination is made.
This is safe because the priv->buffer_mutex still protects the priv
state being modified.

When the kernel panics, one page of kmsg data may be collected and sent to
Hyper-V to aid in diagnosing the failure. The collected kmsg data typically
contains 50 to 100 lines, each of which has a log level prefix that isn't
very useful from a diagnostic standpoint. So tell kmsg_dump_get_buffer()
to not include the log level, enabling more information that *is* useful to
fit in the page.
Requesting in stable kernels, since many kernels running in production are
stable releases.

As description for DIV_ROUND_CLOSEST in file include/linux/kernel.h.
"Result is undefined for negative divisors if the dividend variable
type is unsigned and for negative dividends if the divisor variable
type is unsigned."
In current code, the FIXPT_DIV uses DIV_ROUND_CLOSEST but has not
checked sign of divisor before using. It makes undefined temperature
value in case the value is negative.
This patch fixes to satisfy DIV_ROUND_CLOSEST description
and fix bug too. Note that the variable name "reg" is not good
because it should be the same type as rcar_gen3_thermal_read().
However, it's better to rename the "reg" in a further patch as
cleanup.

/* KHz mW */
{ 1008000, 36, 0 },

"The OMAP developers are particularly active at hunting down
regressions, so this is a separate branch with OMAP specific

As Tony explains
"The recent display subsystem (DSS) related platform data changes
caused display related regressions for suspend and resume. Looks
like I only tested suspend and resume before dropping the legacy
platform data, and forgot to test it after dropping it. Turns out
the main issue was that we no longer have platform code calling
pm_runtime_suspend for DSS like we did for the legacy platform data
case, and that fix is still being discussed on the dri-devel list
and will get merged separately. The DSS related testing exposed a
pile other other display related issues that also need fixing
though":
- Fix ti-sysc optional clock handling and reset status checks for
devices that reset automatically in idle like DSS
- Ignore ti-sysc clockactivity bit unless separately requested to
avoid unexpected performance issues
- Init ti-sysc framedonetv_irq to true and disable for am4
- Avoid duplicate DSS reset for legacy mode with dts data
- Remove LCD timings for am4 as they cause warnings now that we're
using generic panels

- Fix omap_prm reset deassert as we still have drivers setting the
pm_runtime_irq_safe() flag
- Flush posted write for ti-sysc enable and disable
- Fix droid4 spi related errors with spi flags
- Fix am335x USB range and a typo for softreset
- Fix dra7 timer nodes for clocks for IPU and DSP

- Prevent pocketgeagle header line signal from accidentally setting

Fixes for omaps for v5.8
The recent display subsystem (DSS) related platform data changes caused
display related regressions for suspend and resume. Looks like I only
tested suspend and resume before dropping the legacy platform data, and
forgot to test it after dropping it. Turns out the main issue was that
we no longer have platform code calling pm_runtime_suspend for DSS like
we did for the legacy platform data case, and that fix is still being
discussed on the dri-devel list and will get merged separately. The DSS
related testing exposed a pile other other display related issues that
also need fixing though:
- Fix ti-sysc optional clock handling and reset status checks
for devices that reset automatically in idle like DSS
- Ignore ti-sysc clockactivity bit unless separately requested
to avoid unexpected performance issues
- Init ti-sysc framedonetv_irq to true and disable for am4
- Avoid duplicate DSS reset for legacy mode with dts data
- Remove LCD timings for am4 as they cause warnings now that we're
using generic panels
Then there is a pile of other fixes not related to the DSS:
- Fix omap_prm reset deassert as we still have drivers setting the
pm_runtime_irq_safe() flag
- Flush posted write for ti-sysc enable and disable
- Fix droid4 spi related errors with spi flags
- Fix am335x USB range and a typo for softreset
- Fix dra7 timer nodes for clocks for IPU and DSP
- Drop duplicate mailboxes after mismerge for dra7

Pull kgdb fixes from Daniel Thompson:
"The main change here is a fix for a number of unsafe interactions
between kdb and the console system. The fixes are specific to kdb
(pure kgdb debugging does not use the console system at all). On
systems with an NMI then kdb, if it is enabled, must get messages to
the user despite potentially running from some "difficult" calling
contexts. These fixes avoid using the console system where we have
been provided an alternative (safer) way to interact with the user
and, if using the console system in unavoidable, use oops_in_progress
for deadlock avoidance. These fixes also ensure kdb honours the
console enable flag.
Also included is a fix that wraps kgdb trap handling in an RCU read
lock to avoids triggering diagnostic warnings. This is a wide lock
scope but this is OK because kgdb is a stop-the-world debugger. When
we stop the world we put all the CPUs into holding pens and this
inhibits RCU update anyway"

In kgdb context, calling console handlers aren't safe due to locks used
in those handlers which could in turn lead to a deadlock. Although, using
oops_in_progress increases the chance to bypass locks in most console
handlers but it might not be sufficient enough in case a console uses
more locks (VT/TTY is good example).
Currently when a driver provides both polling I/O and a console then kdb
will output using the console. We can increase robustness by using the
currently active polling I/O driver (which should be lockless) instead
of the corresponding console. For several common cases (e.g. an
embedded system with a single serial port that is used both for console
output and debugger I/O) this will result in no console handler being
used.
In order to achieve this we need to reverse the order of preference to
use dbg_io_ops (uses polling I/O mode) over console APIs. So we just
store "struct console" that represents debugger I/O in dbg_io_ops and
while emitting kdb messages, skip console that matches dbg_io_ops
console in order to avoid duplicate messages. After this change,
"is_console" param becomes redundant and hence removed.

If the i2c bus driver ignores the I2C_M_RECV_LEN flag (as some of
them do), it is possible for an I2C_SMBUS_BLOCK_DATA read issued
on some random device to return an arbitrary value in the first
byte (and nothing else). When this happens, i2c_smbus_xfer_emulated()
will happily write past the end of the supplied data buffer, thus
causing Bad Things to happen. To prevent this, check the size
before copying the data block and return an error if it is too large.
