Marek Szyprowski 3aa2a5c140 drm/exynos: gem: Simplify access to exynos GEM objects 
Replace all calls to exynos_drm_gem_get_{dma_addr,size}, by a simpler
function exynos_drm_gem_get(). This lets the caller to get access to
exynos_drm_gem object and extract any information about GEM object
without searching object tree for getting each parameter.

Marek Szyprowski eb4d9796fa drm/exynos: g2d: Convert to driver component API 
Exynos G2D driver is the last client of the custom Exynos 'sub-driver'
framework. In the current state it doesn't really resolve any of the
issues it has been designed for, as Exynos DRM is already built only
as a single kernel module. Remove the custom 'sub-driver' framework and
simply use generic component framework also in G2D driver.

Inki Dae 2d3bda7071 Fixups 
- Fix several problems to IPPv2 merged to mainline recentely.
   . An align problem of width size that IPP driver incorrectly
     calculated the real buffer size.
   . Horizontal and vertical flip problem.
   . Per-plane global alpha for XRGB modes.
   . Incorrect variant of the YUV modes.
 - Fix plane overlapping problem.
   . The stange order of overlapping planes on XRGB modes
     by setting global alpha value to maximum value.
 
 Cleanup
 - Rename a enum type, drm_ipp_size_id, to one specific to Exynos,
   drm_exynos_ipp_limit_type.
 - Replace {un/reference} with {put,get} functions.
   . it replaces several reference/unreference functions with Linux
     kernel nameing standard.

Boris Brezillon 5fa8e4a221 drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULL 
Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.

Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".

Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.

Kees Cook a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc() 
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

Marek Szyprowski 9913f74fe1 drm/exynos: ipp: Add IPP v2 framework 
This patch adds Exynos IPP v2 subsystem and userspace API.

New userspace API is focused ONLY on memory-to-memory image processing.
The two remainging operation modes of obsolete IPP v1 API (framebuffer
writeback and local-path output with image processing) can be implemented
using standard DRM features: writeback connectors and additional DRM planes
with scaling features.

V2 IPP userspace API is based on stateless approach, which much better fits
to memory-to-memory image processing model. It also provides support for
all image formats, which are both already defined in DRM API and supported
by the existing IPP hardware modules.

The API consists of the following ioctls:
- DRM_IOCTL_EXYNOS_IPP_GET_RESOURCES: to enumerate all available image
  processing modules,
- DRM_IOCTL_EXYNOS_IPP_GET_CAPS: to query capabilities and supported image
  formats of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_GET_LIMITS: to query hardware limitiations for
  selected image format of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_COMMIT: to perform operation described by the
  provided structures (source and destination buffers, operation rectangle,
  transformation, etc).

The proposed userspace API is extensible. In the future more advanced image
processing operations can be defined to support for example blending.

Userspace API is fully functional also on DRM render nodes, so it is not
limited to the root/privileged client.

Internal driver API also has been completely rewritten. New IPP core
performs all possible input validation, checks and object life-time
control. The drivers can focus only on writing configuration to hardware
registers. Stateless nature of DRM_IOCTL_EXYNOS_IPP_COMMIT ioctl simplifies
the driver API. Minimal driver needs to provide a single callback for
starting processing and an array with supported image formats.

Douglas Anderson 7bb3bb4d56 drm/bridge: analogix_dp: Split the platform-specific poweron in two parts 
Some of the platform-specific stuff in rockchip_dp_poweron() needs to
happen before the generic code.  Some needs to happen after.  Let's
split the callback in two.

Specifically we can't start doing PSR work until _after_ the whole
controller is up, so don't set the enable until the end.

Dave Airlie 2e1d6eab50 Remove Exynos specific framebuffer structure and 
relevant functions.
 - it removes exynos_drm_fb structure which is a wrapper of
   drm_framebuffer and unnecessary two exynos specific callback
   functions, exynos_drm_destory() and exynos_drm_fb_create_handle()
   because we can reuse existing drm common callback ones instead.
