Subject: [PATCH 2/2] Don't be TOO severe when looking for the IRQ names
Using strncmp with an all caps result in the driver being unable to
initialize itself when using the mainlined RK3288 DTS files, since they
define the IRQ names as "job", "mmu" and "gpu" instead of "JOB", "MMU"
and "GPU".
strncmp calls have been replaced by strncasecmp calls in order to
avoid such issue.

Subject: [PATCH] Added the new "compatible" list, mainly used by Rockchip
Because, you know, all the Mali Midgard GPU used to define the GPU
using the 'compatible = "arm,mali-midgard"' property, which worked fine.
But it was removed.
They replaced the "arm,mali-midgard" node by "arm,mali-tXXX" where XXX
is the GPU series, and added "arm,rk3288-mali" which is used by nothing.
Which broke the Mali Midgard GPL kernel driver.
This patch fixes this issue.

This patch is due the changes provoked by series of commit ending
at 513ae785c63c30741e46f43960213d4ae5382ec0, and removing the
setup_timer macros.
The previous patches replaced made sure that timers were all set
up with setup_timer and replaced setup_timer calls by timer_setup
calls.
This changed was introduced in the 4.15-rc1.

Subject: [PATCH] drivers: gpu: Arm: Midgard: Replace ACCESS_ONCE by READ_ONCE
The ACCESS_ONCE macro has now been removed in the 4.15.0-rc4,
and every ACCESS_ONCE call has been replaced by either READ_ONCE or
WRITE_ONCE calls.
Since the Midgard GPU drivers are not mainlined, the change
needs to be applied manually.
See commit b899a850431e2dd0943205a63a68573f3e312d0d and its parents,
for more informations.

Subject: [PATCH] gpu: arm: midgard: Remove sys_close references
sys_close is now replaced by ksys_close in an effort to remove
in-kernel system calls references.
See 2ca2a09d6215fd9621aa3e2db7cc9428a61f2911 and
https://lkml.org/lkml/2018/3/25/93 for more details.

Subject: [PATCH] GPU: ARM: Midgard: Adapt to the new mmap call checks.
Now, I don't know if this driver is just one of these "buggy" drivers
Linus is talking about, or if this is just standard GPU procedure.
Anyway, this patch is due to this change by Linus Torvalds :
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=be83bbf806822b1b89e0a0f23cd87cddc409e429
And the fix is inspired by :
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76ef6b28ea4f81c3d511866a9b31392caa833126

Subject: [PATCH] GPU: Mali: Midgard: remove rcu_read_lock references
This patch is actually based on @mihailescu2m patch.
This removes references to rcu_read_lock when acquiring the OPP table,
as it is useless since.
See :
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/base/power/opp/core.c?id=5b650b388844f26c61c70564865598836d05dcb3
The current rcu_read_lock actually generates some issues with recent
kernels.
See here :
https://community.arm.com/graphics/f/discussions/9207/midgard-r20p0-kernel-drivers-errors
The patch has been recreated since it does not apply directly on r19p0
sources (I guess the affected line numbers slightly differ...).
@mihailescu2m patch for the Mali Midgard r20p0 kernel driver can be
acquired here :
https://github.com/mihailescu2m/linux/commit/bbe73c3c1143e5991bdcaee3afaecf5c31af0647
