irrevocable (except as stated in this section) patent license to make, have
made, use, offer to sell, sell, import, and otherwise transfer the Work, where
such license applies only to those patent claims licensable by such Contributor
that are necessarily infringed by their Contribution(s) alone or by combination
of their Contribution(s) with the Work to which such Contribution(s) was
submitted. If You institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
Contribution incorporated within the Work constitutes direct or contributory
patent infringement, then any patent licenses granted to You under this License
for that Work shall terminate as of the date such litigation is filed.

following places: within a NOTICE text file distributed as part of the
Derivative Works; within the Source form or documentation, if provided along
with the Derivative Works; or, within a display generated by the Derivative
Works, if and wherever such third-party notices normally appear. The contents of
the NOTICE file are for informational purposes only and do not modify the
License. You may add Your own attribution notices within Derivative Works that
You distribute, alongside or as an addendum to the NOTICE text from the Work,
provided that such additional attribution notices cannot be construed as
modifying the License.
You may add Your own copyright statement to Your modifications and may provide
additional or different license terms and conditions for use, reproduction, or
distribution of Your modifications, or for any such Derivative Works as a whole,
provided Your use, reproduction, and distribution of the Work otherwise complies

#### 5. Submission of Contributions
Unless You explicitly state otherwise, any Contribution intentionally submitted
for inclusion in the Work by You to the Licensor shall be under the terms and
conditions of this License, without any additional terms or conditions.

Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
including, without limitation, any warranties or conditions of TITLE,
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
solely responsible for determining the appropriateness of using or

liable to You for damages, including any direct, indirect, special, incidental,
or consequential damages of any character arising as a result of this License or
out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
any and all other commercial damages or losses), even if such Contributor has
been advised of the possibility of such damages.
#### 9. Accepting Warranty or Additional Liability
While redistributing the Work or Derivative Works thereof, You may choose to
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
other liability obligations and/or rights consistent with this License. However,
in accepting such obligations, You may act only on Your own behalf and on Your

Sitronix ST7701S MIPI-DSI display panel, driven over ESP-IDF's esp_lcd_st7701 component (DPI/DBI
interface, ESP32-P4 and other SOC_MIPI_DSI_SUPPORTED targets only). Owns the MIPI DSI PHY LDO
channel and DSI bus directly, so unlike SPI/RGB panels it has no parent bus controller device.

allow-tearing:
type: boolean
default: false
description: By default, when draw_bitmap's color_data is one of the panel's own frame
buffers (i.e. LVGL is bound directly onto them), draw_bitmap waits for a full scan-out to
complete before returning so the caller can't start overwriting a buffer still being
displayed. Set this to trade away that tear-free guarantee for lower latency (e.g. when
other tasks occasionally block timing for long enough that waiting causes visible stalls).
init-sequence:
type: array
element-type: uint8_t
description: >
Custom vendor bring-up sequence, flattened into bytes as a run of
[cmd, data-length, delay-ms, data-length bytes of data...] entries, e.g.
`init-sequence = [0x11 0 120 0x29 0 20];`.
Omit to use the ST7701 component's own built-in default sequence.
