This series enables a set of miscellaneous features for Billion Capture+
(a handset using the MSM8953 SoC released in 2017):
- Panel and GPU
- Touchscreen
- WiFi + Bluetooth
- Hall sensor

Patches 1 and 2 provide a driver for Novatek NT35532 and its corresponding
devicetree bindings, required for enabling panel in DTS. The remaining
patches are all DTS changes, aimed to enable the features listed above.

Changes in v5:
- Based on dts-coding-style.html ("Nodes without unit addresses shall be
ordered alpha-numerically by the node name. For a few node types, they
can be ordered by the main property, e.g. pin configuration states
ordered by value of “pins” property."), sort pinctrl states by GPIO
index (Konrad);
- Pick up tags;
- Link to v4: https://lore.kernel.org/r/20260327-rimob-new-features-v4-0-06edff9c4509@protonmail.com

Changes in v4:
- (patch 1/6): added a new compatible (since it's not possible to
identify panel vendor/id), matching user of this device and leaving
novatek,nt35532 as fallback (Dmitry);
- (patch 2/6):
- according to bindings changes, make panel driver handling multiple
panels paired with NT35532 and use specific compatible/data;
- due to changes applied to panel code, remove tag received previously
by Dmitry.
- (patch 3/6):
- use a specific panel compatible, according to bindings changes;
- remove 'output-high' property from panel pinctrl, since panel is not
reset.
- Link to v3: https://lore.kernel.org/r/20260321-rimob-new-features-v3-0-d4b8ee867de7@protonmail.com

Changes in v3:
- (patch 1/6): removed avdd, avee and vci supplies from 'required' properties;
- (patch 2/6):
- removed "select VIDEOMODE_HELPERS" from nt35532 Kconfig entry, since
its functions are not used (but this option is enabled and its code
compiled anyway) by nt35532 panel driver;
- pick up tags (Dmitry).
- (patch 3/6): replaced a506_zap.mdt with a506_zap.mbn firmware name
in gpu_zap_shader (Dmitry);
- (patch 5/6): pick up tags (Konrad);
- (patch 6/6): pick up tags (Konrad);
- Link to v2: https://lore.kernel.org/r/20260318-rimob-new-features-v2-0-c1bf8917449e@protonmail.com

Changes in v2:
- (patch 1/6): define power supplies in the bindings as per datasheet
and update example;
- (patch 2/6): add blank lines where required between mipi dsi write
sequences in nt35532_on() function and make use of names for mipi dcs
commands, instead of hex numbers, to improve readibility (Dmitry);
- (patch 3/6): move pinctrl lines ibto panel node and get rid of
sleep/reset state, since panel just uses one pinctrl state for
default/sleep (Dmitry). Also, update power supplies according to
bindings;
- (patch 4/6): pick up tags (Konrad,Dmitry);
- (patch 6/6): squash hall sensor node into gpio-keys (Dmitry);
- Link to v1: https://lore.kernel.org/r/20260308-rimob-new-features-v1-0-aa2c330572c0@protonmail.com
