ARM: dts: AM335x: Make charge delay a DT parameter for TSC
The charge delay value is by default 0x400. But it can be set to lower values on some boards, as long as false pen-ups are avoided. Lowering the value increases the sampling rate (though current sampling rate is sufficient for TSC operation). In some boards, the value has to be increased to avoid false pen-up events. Hence, charge delay has been made a DT parameter. Signed-off-by: NVignesh R <vigneshr@ti.com> Acked-by: NTony Lindgren <tony@atomide.com> Signed-off-by: NDmitry Torokhov <dmitry.torokhov@gmail.com>
