UPSTREAM: Coccinelle: misc: Improve the matching of rules

Currently because of the left associativity of the operators, pattern
IRQF_ONESHOT | flags does not match with the pattern when we have more
than one flag after the disjunction. This eventually results in giving
false positives by the script. This patch eliminates these FPs by
improving the rule.

reported on are the same as the sites that were identified as having the

UPSTREAM: coccinelle: catch krealloc() on devm_*() allocated memory

krealloc() must not be used against devm_*() allocated
memory regions:

- if a bigger memory is to be allocated, krealloc() and
  __krealloc() could return a different pointer than the
  one given to them, creating a memory region which is not
  managed, thus it will not be automatically released on
  device removal.

- if a bigger memory is to be allocated, krealloc() could
  kfree() the managed memory region which is passed to it.
  The old pointer is left registered as a resource for the
  device. On device removal, this dangling pointer will be
  used and an unrelated memory region could be released.

- if the requested size is equal to 0, krealloc() can also
  just behave like kfree(). Here too, the old pointer is
  kept associated with the device. On device removal, this
  invalid pointer will be used and an unrelated memory
  region could be released.

For all these reasons, krealloc() must not be used on a
pointer returned by devm_*() functions.

Unsigned expressions cannot be lesser than zero. Presence of comparisons

gcc can detect such comparisons also using -Wtype-limits switch, but it warns

BACKPORT: FROMLIST: mmc: dw_mmc: introduce timer for broken command transfer over scheme

Per the databook of designware mmc controller 2.70a, table 3-2, cmd
done interrupt should be fired as soon as the the cmd is sent via
cmd line. And the response timeout interrupt should be generated
unconditioinally as well if the controller doesn't receive the resp.
However that doesn't seem to meet the fact of rockchip specified Soc
platforms using dwmmc. We have continuously found the the cmd done or
response timeout interrupt missed somehow which took us a long time to
understand what was happening. Finally we narrow down the root to
the reconstruction of sample circuit for dwmmc IP introduced by
rockchip and the buggy design sweeps over all the existing rockchip
Socs using dwmmc disastrously.

It seems no way to work around this bug without the proper break-out
mechanism so that we seek for a parallel pair the same as the handling
for missing data response timeout, namely dto timer. Adding this cto
timer seems easily to handle this bug but it's hard to restrict
the code under the rockchip specified context. So after merging this
patch, it sets up the cto timer for all the platforms using dwmmc IP
which isn't ideal but at least we don't advertise new quirk here.
Fortunately, no obvious performance regression was found by test and the
pre-existing similar catch-all timer for sdhci has proved it's an acceptant
way to make the code as robust as possible.

RK3328 hdmi phy is an upgraded version of 3228 hdmi phy, with
a completely different register layout. It improves physical
and antistatic capabilities.

It's max output bandwidth is same as rk3228 hdmi phy, optimized
up to 3.72Gbps per TMDS link.

power: rk818-charger: fix usb charger undetected

On some platforms (e.g. rk3399), we use extcon notify
framework to receive USB charger notifier from USB PHY
driver. Generally, the USB PHY driver uses a work to check
vbus status and the USB charger type every 2 seconds,
this polling mechanism may cause USB charger undetected
if we plug in/out USB charger quickly.

A typical error case is:
1. Plug in an USB DCP Adapter.
   - USB PHY driver sends notifier to rk818-charger
2. Plug out the USB Adapter, and plug in again immediately
   - rk818 detects plug out irq, and turns off charging
   - USB PHY driver schedule work doesn't detect the plug
     out/in operations, and doesn't send usb charger notifier

Fortunately, rk818 can detect plug in irq, so let's check
the USB charger type in rk818 plug in irq handler.

UPSTREAM: drm: introduce pipe color correction properties

Patch based on a previous series by Shashank Sharma.

This introduces optional properties to enable color correction at the
pipe level. It relies on 3 transformations applied to every pixels
displayed. First a lookup into a degamma table, then a multiplication
of the rgb components by a 3x3 matrix and finally another lookup into
a gamma table.

The following properties can be added to a pipe :
  - DEGAMMA_LUT : blob containing degamma LUT
  - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT
  - CTM : transformation matrix applied after the degamma LUT
  - GAMMA_LUT : blob containing gamma LUT
  - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT

DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by
the driver to tell userspace applications what sizes should be the
lookup tables in DEGAMMA_LUT and GAMMA_LUT.

A helper is also provided so legacy gamma correction is redirected
through these new properties.

v2: Register LUT size properties as range

v3: Fix round in drm_color_lut_get_value() helper
    More docs on how degamma/gamma properties are used

v4: Update contributors

v5: Rename CTM_MATRIX property to CTM (Doh!)
    Add legacy gamma_set atomic helper
    Describe CTM/LUT acronyms in the kernel doc

v6: Fix missing blob unref in drm_atomic_helper_crtc_reset

Thus the tests around the calls are not needed.

drm/edid: Clear the old hdmi info before parsing display info

The current EDID might not support advanced HDMI 2.0 features.
Leaving old hdmi info in the drm_display_info will make display
work not okay, when switching display from HDMI 2.0 device to
HDMI 1.4 device.

UPSTREAM: drm/edid: detect SCDC support in HF-VSDB

This patch does following:
- Adds a new structure (drm_hdmi_info) in drm_display_info.
  This structure will be used to save and indicate if sink
  supports advanced HDMI 2.0 features
- Adds another structure drm_scdc within drm_hdmi_info, to
  reflect scdc support and capabilities in connected HDMI 2.0 sink.
- Checks the HF-VSDB block for presence of SCDC, and marks it
  in scdc structure
- If SCDC is present, checks if sink is capable of generating
  SCDC read request, and marks it in scdc structure.

V2: Addressed review comments
  Thierry:
  - Fix typos in commit message and make abbreviation consistent
    across the commit message.
  - Change structure object name from hdmi_info -> hdmi
  - Fix typos and abbreviations in description of structure drm_hdmi_info
    end the description with a full stop.
  - Create a structure drm_scdc, and keep all information related to SCDC
    register set (supported, read request supported) etc in it.

  Ville:
  - Change rr -> read_request
  - Call drm_detect_scrambling function drm_parse_hf_vsdb so that all
    of HF-VSDB parsing can be kept in same function, in incremental
    patches.
