Subject: drm/i915/psr: Try to program link training times correctly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The default of 0 is 500us of link training, but that's not enough for
some platforms. Decoding this correctly means we're using 2.5ms of
link training on these platforms, which fixes flickering issues
associated with enabling PSR.
v2: Unbotch the math a bit.
v3: Drop debug hunk.
v4: Improve commit message.

From de26859dcf363d520cc44e59f6dcaf20ebe0aadf Mon Sep 17 00:00:00 2001

Subject: rtlwifi: Fix scheduling while atomic error from commit 49f86ec21c01
Commit 49f86ec21c01 ("rtlwifi: Change long delays to sleeps") was correct
for most cases; however, driver rtl8192ce calls the affected routines while
in atomic context. The kernel bug output is as follows:
BUG: scheduling while atomic: wpa_supplicant/627/0x00000002
[...]

[<ffffffff810e8b80>] ? hrtimer_init+0x120/0x120
[<ffffffff815c5ba6>] ? schedule_hrtimeout_range_clock+0x96/0x120
[<ffffffff815c5c43>] schedule_hrtimeout_range+0x13/0x20
[<ffffffff815c568f>] usleep_range+0x4f/0x70
[<ffffffffa0667218>] rtl_rfreg_delay+0x38/0x50 [rtlwifi]
[<ffffffffa06dd0e7>] rtl92c_phy_config_rf_with_headerfile+0xc7/0xe0 [rtl8192ce]
To fix this bug, three of the changes from delay to sleep are reverted.
Unfortunately, one of the changes involves a delay of 50 msec. The calling
code will be modified so that this long delay can be avoided; however,
this change is being pushed now to fix the problem in kernel 4.6.0.
