+SM2135 LED driver

+
+Component
+---------
+
+The SM2135 component represents a SM2135 LED diver chain
+(`SM2135 description <https://github.com/arendst/Sonoff-Tasmota/files/3656603/SM2135E_zh-CN_en-US_translated.pdf>`__,
+`SM2135 description <https://github.com/arendst/Sonoff-Tasmota/files/3656603/SM2135E_zh-CN_en-US_translated.pdf>`__) in
+ESPHome. Communication is done with two GPIO pins (MOSI and SCLK).
+It is used in some smart light bulbs:
+
+- Calex Smart RGB Reflector LED lamp (GU10)
+- LSC Smart GU10 
+
+To use the channels of this components, you first need to setup the
+global ``sm2135`` hub and give it an id, and then define the
+:ref:`individual output channels <sm2135-output>`.
+
+.. code-block:: yaml
+
+    # Example configuration entry
+    sm2135:
+      data_pin: GPIO12
+      clock_pin: GPIO14
+
+    # Individual outputs
+    output:
+      - platform: sm2135
+        id: output_red
+        channel: 0
+        max_power: 0.8
+      - platform: sm2135
+        id: output_green
+        channel: 1
+        max_power: 0.8
+      - platform: sm2135
+        id: output_blue
+        channel: 2
+        max_power: 0.8
+      - platform: sm2135
+        id: output_white
+        channel: 3
+        max_power: 0.8
+      - platform: sm2135
+        id: output_warmwhite
+        channel: 4
+        max_power: 0.8
+
+Configuration variables:
+************************
+
+-  **data_pin** (**Required**, :ref:`config-pin_schema`): The pin used for MOSI.
+-  **clock_pin** (**Required**, :ref:`config-pin_schema`): The pin which SCLK is
+   connected to.
+-  **id** (*Optional*, :ref:`config-id`): The id to use for
+   this ``sm2135`` component. Use this if you have multiple SM2135 chains
+   connected at the same time.

+.. _sm2135-output:
+
+Driver Output
+-------------
+
+The SM2135 output component exposes a SM2135 channel of a global
+:ref:`sm2135-component` as a float output.
+
+.. code-block:: yaml
+
+    # Example configuration entry
+    sm2135:
+      data_pin: GPIO12
+      clock_pin: GPIO14
+
+    # Individual outputs
+    output:
+      - platform: sm2135
+        id: output_red
+        channel: 0
+        max_power: 0.8
+      - platform: sm2135
+        id: output_green
+        channel: 1
+        max_power: 0.8
+      - platform: sm2135
+        id: output_blue
+        channel: 2
+        max_power: 0.8
+      - platform: sm2135
+        id: output_white
+        channel: 3
+        max_power: 0.8
+      - platform: sm2135
+        id: output_warmwhite
+        channel: 4
+        max_power: 0.8
+
+Configuration variables:
+************************
+
+- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
+- **channel** (**Required**, int): Chose the channel of the SM2135 chain of
+  this output component.
+- **sm2135_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
+  :ref:`sm2135-component`.
+  Use this if you have multiple SM2135 chains you want to use at the same time.
+- All other options from :ref:`Output <config-output>`.
+
+.. note::
+
+    The white LEDs are much brighter than the color LEDs. To get uniform brightness 
+    for both color and white you will need to limit the white led power.
+
+.. note::
+
+    This driver does not support enabling of both the color and the white channels
+    at the same time. Therefore, the :ref:`rgbw_color_interlock` should be set to true
+    when using this driver.
