不知道需要DTS里那里要改包括触摸液晶 framework需要修改吗

以x3399_marshmallow这个源码为例来说明：

进入kernel/arch/arm64/boot/dts/rockchip 这个目录

155 &rk_screen {

156    assigned-clocks = <&cru PLL_VPLL>;

157    assigned-clock-rates = <245000000>;

158    #include "lcd-mipi-7inch-wy070ml.dtsi"

159 /*  #include "lcd-mipi-7inch-r69429.dtsi" */

160 /* #include "lcd-edp-ltl101dl03.dtsi" */

161    /* #include "lcd-edp-lp079qx1.dtsi" */

162 };

lcd-mipi-7inch-wy070ml.dtsi表示我们的7寸mipi屏幕

lcd-edp-ltl101dl03.dtsi表示10.1寸edp屏幕

155 &rk_screen {

156    assigned-clocks = <&cru PLL_VPLL>;

157    assigned-clock-rates = <245000000>;

158  /* #include "lcd-mipi-7inch-wy070ml.dtsi" */

159 /*  #include "lcd-mipi-7inch-r69429.dtsi" */

160 #include "lcd-edp-ltl101dl03.dtsi"

161    /* #include "lcd-edp-lp079qx1.dtsi" */

162 };

这样就支持10.1寸edp屏幕了

120 &i2c1 {

121    status = "okay";

122

123    gsl3680@40 {

124       compatible = "tchip,gsl3680";

125       reg = <0x40>;

126       touch-gpio = <&gpio1 20 IRQ_TYPE_EDGE_RISING>;

127       reset-gpio = <&gpio1 9 GPIO_ACTIVE_LOW>;

128       max-x = <1024>;

129       max-y = <600>;

130    };

131

132    gt9xx: gt9xx@14 {

133       compatible = "goodix,gt9xx";

134       reg = <0x14>;

135       touch-gpio = <&gpio1 20 IRQ_TYPE_EDGE_RISING>;

136       reset-gpio = <&gpio1 9 GPIO_ACTIVE_LOW>;

137       max-x = <1200>;

138       max-y = <1920>;

139       tp-size = <101>;

140       status = "disabled";

141    };

142

143    /*

144    gsl3673: gsl3673@40 {

145       compatible = "GSL,GSL3673";

146       reg = <0x40>;

147       screen_max_x = <1536>;

148       screen_max_y = <2048>;

149       irq_gpio_number = <&gpio1 20 IRQ_TYPE_LEVEL_LOW>;

150       rst_gpio_number = <&gpio1 9 GPIO_ACTIVE_HIGH>;

151    };

152    */

153 };

此时使用的触摸是 gsl3680，而10.1edp对应的触摸是gt9xx的，因此修改为

120 &i2c1 {

121    status = "okay";

122

123    gsl3680@40 {

124       compatible = "tchip,gsl3680";

125       reg = <0x40>;

126       touch-gpio = <&gpio1 20 IRQ_TYPE_EDGE_RISING>;

127       reset-gpio = <&gpio1 9 GPIO_ACTIVE_LOW>;

128       max-x = <1024>;

129       max-y = <600>;

130       status = "disabled";

130    };

131

132    gt9xx: gt9xx@14 {

133       compatible = "goodix,gt9xx";

134       reg = <0x14>;

135       touch-gpio = <&gpio1 20 IRQ_TYPE_EDGE_RISING>;

136       reset-gpio = <&gpio1 9 GPIO_ACTIVE_LOW>;

137       max-x = <1200>;

138       max-y = <1920>;

139       tp-size = <101>;

140

141    };

142

143    /*

144    gsl3673: gsl3673@40 {

145       compatible = "GSL,GSL3673";

146       reg = <0x40>;

147       screen_max_x = <1536>;

148       screen_max_y = <2048>;

149       irq_gpio_number = <&gpio1 20 IRQ_TYPE_LEVEL_LOW>;

150       rst_gpio_number = <&gpio1 9 GPIO_ACTIVE_HIGH>;

151    };

152    */

153 };
