The Cluster windows of upcoming VOP on rk3576 also support
linear YUV support, we need to set uv swap bit for it.
As the VOP2_WIN_UV_SWA register defined on rk3568/rk3588 is
0x, so this register will not be touched on these
two platforms.

Hi,
this small series improves debugging the tc358767 driver by using
dev_err_probe for additional information (patch 1) and print IRQ
debug output only if hotplug status actually changed.
Changes inv 3:
* Collected Robert's and Dmitry' R-b
Changes in v2:
* Added patch for supporting write-only
The function calls preceding these returns can return -EPROBE_DEFER. So
use dev_err_probe to add some information to
/sys/kernel/debug/devices_deferred

Most registers are read-writable, but some are only RO or even WO.
regmap does not support using readable_reg and wr_table when outputting
in debugfs, so switch to writeable_reg.
First check for RO or WO registers and fallback tc_readable_reg() for the
leftover RW registers.

Deferred I/O requires struct page for framebuffer memory, which is
not guaranteed for all DMA ranges. We thus only install deferred I/O
if we have a framebuffer that requires it.
A reported bug affected the ipu-v3 and pl111 drivers, which have video
memory in either Normal or HighMem zones

We enable most W=1 warnings by default subsystem wide. Also enable
warnings on unused static inlines when building with clang.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
