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.

If a drm_file name is set append it to the process name.
This information is useful with the virtio/native-context driver: this

Giving the opportunity to userspace to associate a free-form
name with a drm_file struct is helpful for tracking and debugging.
This is similar to the existing DMA_BUF_SET_NAME ioctl.
Access to name is protected by a mutex, and the 'clients' debugfs

The alpha setup should start from the second layer, the current calculation
starts incorrectly from the first layer, a negative offset will be obtained
in the following formula:
offset = (mixer_id + zpos - 1) * 0x10

Add support for Exynos 7870 DECON in the Exynos 7 DECON driver.
Some Exynos 7 series SoCs (Exynos 7580 onwards) have different
register values. In order to address such changes, include a driver
data struct (named decon_data) so that correct base addresses and
shift values can be provided.

This patch series aims at adding support for Exynos7870's DECON in the
Exynos7 DECON driver. It introduces a driver data struct so that support
for DECON on other SoCs can be added to it in the future.
It also fixes a few bugs in the driver, such as functions recieving bad
pointers.
Test
decon_clear_channels() and decon_wait_for_vblank() accept a pointer to
struct exynos_drm_crtc. However, these functions are called when the
crtc is still uninitialized. Moreover, both functions use the pointer to
retrieve and use struct decon_context, which is initialized.
Modify the functions to
The clkdiv values are incorrect as ideal_clk is in kHz and the clock
rate of vclk is in Hz. Multiply 1000 to ideal_clk to bring it to Hz.

The DECON channels are not cleared properly as the windows aren't
shadow protected. When accompanied with an IOMMU, it pagefaults, and
the kernel panics.
Implement shadow protect/unprotect, along with a standalone update,
for channel clearing to properly take effect.

Hi,
as noted in the cover letter, I think the connection to DRM is a red herring.
