Stephen Boyd a3ee9e0b57 drm/panel: boe-tv101wum-nl6: Ensure DSI writes succeed during disable
The unprepare sequence has started to fail after moving to panel bridge
code in the msm drm driver (commit 007ac0262b ("drm/msm/dsi: switch to
DRM_PANEL_BRIDGE")). You'll see messages like this in the kernel logs:

   panel-boe-tv101wum-nl6 ae94000.dsi.0: failed to set panel off: -22

This is because boe_panel_enter_sleep_mode() needs an operating DSI link
to set the panel into sleep mode. Performing those writes in the
unprepare phase of bridge ops is too late, because the link has already
been torn down by the DSI controller in post_disable, i.e. the PHY has
been disabled, etc. See dsi_mgr_bridge_post_disable() for more details
on the DSI .

Split the unprepare function into a disable part and an unprepare part.
For now, just the DSI writes to enter sleep mode are put in the disable
function. This fixes the panel off routine and keeps the panel happy.

My Wormdingler has an integrated touchscreen that stops responding to
touch if the panel is only half disabled too. This patch fixes it. And
finally, this saves power when the screen is off because without this
fix the regulators for the panel are left enabled when nothing is being
displayed on the screen.

Arnd Bergmann 9f20c9f4b1 accel: fix CONFIG_DRM dependencies
At the moment, accel drivers can be built-in even with CONFIG_DRM=m,
but this causes a link failure:

x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_dev_init':
ivpu_drv.c:(.text+0x1535): undefined reference to `drmm_kmalloc'

The problem is that DRM_ACCEL is a 'bool' symbol, so driver that
only depend on DRM_ACCEL but not also on DRM do not see the restriction
to =m configs.

To ensure that each accel driver has an implied dependency on CONFIG_DRM,
enclose the entire Kconfig file in an if/endif check.

Pali Rohár 5a73638212 arm64: dts: marvell: Fix compatible strings for Armada 3720 boards
All Armada 3720 boards have Armada 3720 processor which is of Armada 3700
family and do not have Armada 3710 processor. So none of them should have
compatible string for Armada 3710 processor.

Fix compatible string for all these boards by removing wrong processor
string "marvell,armada3710" and adding family string "marvell,armada3700"
as the last one. (Note that this is same way how are defined Armada 3710
DTS files).

riscv: switch to relative alternative entries
Instead of using absolute addresses for both the old instrucions and
the alternative instructions, use offsets relative to the alt_entry
values. So this not only cuts the size of the alternative entry, but
also meets the prerequisite for patching alternatives in the vDSO,
since absolute alternative entries are subject to dynamic relocation,
which is incompatible with the vDSO building.

riscv: introduce riscv_has_extension_[un]likely()
Generally, riscv ISA extensions are fixed for any specific hardware
platform, so a hart's features won't change after booting. This
chacteristic makes it straightforward to use a static branch to check
if a specific ISA extension is supported or not to optimize
performance.

However, some ISA extensions such as SVPBMT and ZICBOM are handled
via. the alternative sequences.

Basically, for ease of maintenance, we prefer to use static branches
in C code, but recently, Samuel found that the static branch usage in
cpu_relax() breaks building with CONFIG_CC_OPTIMIZE_FOR_SIZE[1]. As
Samuel pointed out, "Having a static branch in cpu_relax() is
problematic because that function is widely inlined, including in some
quite complex functions like in the VDSO. A quick measurement shows
this static branch is responsible by itself for around 40% of the jump
table."

Samuel's findings pointed out one of a few downsides of static branches
usage in C code to handle ISA extensions detected at boot time:
static branch's metadata in the __jump_table section, which is not
discarded after ISA extensions are finalized, wastes some space.

I want to try to solve the issue for all possible dynamic handling of
ISA extensions at boot time. Inspired by Mark[2], this patch introduces
riscv_has_extension_*() helpers, which work like static branches but
are patched using alternatives, thus the metadata can be freed after
patching.
