palkia: separate the gpio pins control for the second touch
There are two touch screen controllers on the Palkia device. One is on the lid; another is on the base. To support the different control path (for example: turning off the base's touch event when we don't want to use it however still keeping the lid's touch event), we use the different gpio pins to control the second touch. As a result, we need to modify the devicetree to adopt this change. With this change, we can control the primary and secondary touch screen controller respectively. BUG=b:149714955 TEST=lid/base touch screen works correctly Change-Id: I1f896e334e51c78300af724cbef8d57641ae5612 Signed-off-by: Zhuohao Lee <zhuohao@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42185 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
