展锐平台 触摸调试TP bringup
前言
一般lcd和tp应该是一起点亮的，这里分开了，详细lcd点亮方法查看上一篇lcd bringup
参考修改目录
STEP1
把厂商给得驱动放入文件夹ker/kernel6.6/unisoc-modules/touchscreen/
修改对应的Kconfig和makefile,这里是tp驱动是否被加载和编译的关键文件
# # Unisoc touchscreen (NEW )configuration # config TOUCHSCREEN_ILITEK_V3_SPI tristate "ILITEK V3 SPI Support" help This is support ilitek v3 spi touchscreen. if you want to use ilitek v3 spi touchscreen. please say "m".# Makefile for the ILITEK touchscreen driver. ifneq ($(strip $(BSP_KERNEL_VERSION)),kernel5.15) BSP_MODULES_OUT := ${COMMON_OUT_DIR}/unisoc_modules/kernel6.1/touchscreen/ilitek BSP_KERNEL_PATH := ${ROOT_DIR}/kernel6.1 KO_MODULE_OUT := $(BSP_MODULES_OUT) else KO_MODULE_NAME := ilitek KO_MODULE_OUT := $(BSP_MODULES_OUT)/$(KO_MODULE_NAME) endif ccflags-y += -Wall ccflags-y += -I$(srctree)/drivers/unisoc_platform/nest/touchscreen/core/ KO_MODULE_KBUILD := $(CURDIR)/Kbuild .PHONY: modules modules_install clean modules: @mkdir -p $(KO_MODULE_OUT) && ln -snf $(KO_MODULE_KBUILD) $(KO_MODULE_OUT)/Kbuild @ln -snf $(CURDIR) $(KO_MODULE_OUT)/source $(MAKE) -C $(BSP_KERNEL_PATH) M=$(KO_MODULE_OUT) src=$(CURDIR) $@ modules_install: $(MAKE) -C $(BSP_KERNEL_PATH) M=$(KO_MODULE_OUT) $@ # Remove the out directory wholly clean: @#$(MAKE) -C $(BSP_KERNEL_PATH) M=$(KO_MODULE_OUT) src=$(CURDIR) $@ rm -rf $(KO_MODULE_OUT) ########################################################################## ilitek-y := \ ilitek_v3.o \ ilitek_v3_spi.o \ ilitek_v3_qcom.o \ ilitek_v3_ic.o \ ilitek_v3_touch.o \ ilitek_v3_mp.o \ ilitek_v3_hostdl.o \ ilitek_v3_node.o obj-$(CONFIG_TOUCHSCREEN_ILITEK_V3_SPI) += ilitek.omakefile建议参考同级目录的tp驱动
这里ilitek-y
表示：生成 ilitek.o 这个目标文件时，需要把这些 .o 合并进去。
STEP2
在此目录添加对应的dtsi
ker\kernel6.6\unisoc\arch\arm64\boot\dts\sprd\touchscreen

STEP3
在对应的主dtsi中包含tp驱动dtsi
ker\kernel6.6\unisoc\arch\arm64\boot\dts\sprd\ums9360\
#include "../touchscreen/ums9360-touch_ilitek_spi_1600x2400.dtsi"STEP4
展锐平台tp最后跑的是\ker\kernel6.6\unisoc\drivers\unisoc_platform\nest\touchscreen
这里可以通过软链接/脚本的方式把ker\kernel6.6\unisoc-modules\touchscreen\ilitek挪过来
进入目录：
cd ker/kernel6.6/unisoc/drivers/unisoc_platform/nest/touchscreen执行：
ln -s ../../../../../unisoc-modules/touchscreen/ilitek ilitek然后确认：
即可
推上服务器的时候记得把软连接也加上
diff --git a/unisoc/drivers/unisoc_platform/nest/touchscreen/ilitek b/unisoc/drivers/unisoc_platform/nest/touchscreen/ilitek new file mode 120000 index 000000000..a3b5973dd --- /dev/null +++ b/unisoc/drivers/unisoc_platform/nest/touchscreen/ilitek @@ -0,0 +1 @@ +../../../../../unisoc-modules/touchscreen/ilitek/STEP5
加入编译链
unisoc/arch/arm64/configs/sprd_gki_qogirl8.fragment
添加Kconfig对应的宏
CONFIG_TOUCHSCREEN_ILITEK_V3_SPI=munisoc/unisoc_bazels/ums9360_user.bzl & unisoc/unisoc_bazels/ums9360_userdebug.bzl
添加对应的ko模块
"drivers/unisoc_platform/nest/touchscreen/ilitek/ilitek.ko",添加对应的Kconfig和makefile
/unisoc/drivers/unisoc_platform/Kconfig
source "drivers/unisoc_platform/nest/touchscreen/ilitek/Kconfig"/unisoc/drivers/unisoc_platform/Makefile
obj-$(CONFIG_TOUCHSCREEN_ILITEK_V3_SPI) += nest/touchscreen/ilitek/
