From 63bcc4f1e72713eca14c4b08e62bc3c07e67904a Mon Sep 17 00:00:00 2001 From: Jerry Han hanxu5@huaqin.corp-partner.google.com Date: Thu, 1 Aug 2019 15:52:35 +0800 Subject: [PATCH 02/10] [v2,2/2] drm/panel: Add Boe Himax8279d MIPI-DSI LCD panel
Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing, instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file, like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
Something went wrong when you tried to submit v10. Please try again.
Sam

From 23afac4125d1ca70809dc92c5ba6d76a880e92e8 Mon Sep 17 00:00:00 2001 From: Jerry Han hanxu5@huaqin.corp-partner.google.com Date: Thu, 1 Aug 2019 15:57:08 +0800 Subject: [PATCH 03/10] [v3,2/2] drm/panel: Add Boe Himax8279d MIPI-DSI LCD panel
Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
V3:
- Remove unnecessary delays in sending initialization commands (Jitao Shi)
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing, instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file, like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.

- Frefix all function maes with boe_ (Sam)
- Fsed "enable_gpio" replace "reset_gpio", Make it look clearer (Sam)
- Sort include lines alphabetically (Sam)
- Fixed entries in the makefile must be sorted alphabetically (Sam)
- Add send_mipi_cmds function to avoid duplicating the code (Sam)
- Add the necessary delay(reset_delay_t5) between reset and sending the initialization command (Rock wang)
V3:
- Remove unnecessary delays in sending initialization commands (Jitao Shi)
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing, instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file, like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.

Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing, instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file, like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
Something went wrong when you tried to submit v10. Please try again.
Apart from that, seems like the init sequence has changed drastically.
What is the reason behind this? Was there a bug with previous patches?
For reference in v8 the sequence was nearly identical for 8 and 10 inch devices - 8-10 line difference. Now we're looking at ~250 ...

Hi Emil:
These changes are not due to previous bugs. The init code changes for a couple of reasons: During the development of the project, 1: Suppliers of LCDS keep changing the process, optimizing the circuitry, and changing the values of certain registers. 2: Changing display effects, such as color temperature, white balance, gamma values, will also change the values of some registers. 3: 8 and 10 inch devices are different. As they continue to optimize their init code there will be big differences.
And we're going to continue to provide an optimized init code.
Thanks.

Hi Sam： sorry，My reply was late.
I commited to the following commit (d6781e490179 - (HEAD -> tmp, tag: drm-misc-next-2019-08-03) drm/pl111: Drop special pads config check (3 weeks ago) <Linus Walleij>)
I don't know why you executed the error. - Can you paste your mistakes?
I used the following command to join patch. 0005-v5-2-2-drm-panel-Add-Boe-Himax8279d-MIPI-DSI-LCD-pan.patch did not change the code. I just adjusted the form of commit according to your suggestions. so you can skip this patch.
Thank you for your guidance. If there are any questions. I hope you can point them out. I will modify it very quickly.
Thanks.

Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
V3:
- Remove unnecessary delays in sending initialization commands (Jitao Shi)
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing, instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file, like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
