Use the general touchscreen method to config the max pressure for touch tsc2046(data sheet suggest 8 bit pressure), otherwise, for ABS_PRESSURE, when config the same max and min value, weston will meet the following issue,
[17:19:39.183] event1 - ADS7846 Touchscreen: is tagged by udev as: Touchscreen [17:19:39.183] event1 - ADS7846 Touchscreen: kernel bug: device has min == max on ABS_PRESSURE [17:19:39.183] event1 - ADS7846 Touchscreen: was rejected [17:19:39.183] event1 - not using input device '/dev/input/event1'
This will then cause the APP weston-touch-calibrator can't list touch devices.
root@imx6ul7d:~# weston-touch-calibrator could not load cursor 'dnd-move' could not load cursor 'dnd-copy' could not load cursor 'dnd-none' No devices listed.
And accroding to binding Doc, "ti,x-max", "ti,y-max", "ti,pressure-max" belong to the deprecated properties, so remove them. Also for "ti,x-min", "ti,y-min", "ti,x-plate-ohms", the value set in dts equal to the default value in driver, so are redundant, also remove here.

With the following configuration options: CONFIG_OF is not set CONFIG_MTK_PMIC_WRAP=y CONFIG_MTK_SCPSYS=y we get the following build warnings:
CC drivers/soc/mediatek/mtk-pmic-wrap.o drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=] drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=] CC drivers/soc/mediatek/mtk-scpsys.o drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=]
Looking at the code, both drivers can only bind to OF-defined device nodes, so these drivers are useless without OF and should therefore depend on it.
Also drop of_match_ptr() from both drivers. We already know what it will resolve to, so we might as well save cpp some work.
Developers or QA teams who wish to test-build the code can still do so by enabling CONFIG_OF, which is available on all architectures and has no dependencies.
