For the crust: In a medium bowl, combine the gingersnap cookies, butter and salt. Use a measuring cup to gently press the cookie crumb mixture into the bottom of the prepared pan. Freeze for 30 minutes.
For the filling: Using an electric mixer, whip the cream cheese, pumpkin, powdered sugar, cinnamon, cardamom, nutmeg, salt and cloves in a large bowl until creamy and smooth, about 5 minutes. Carefully fold in the coconut whipped topping with a rubber spatula. Pour into the crust and refrigerate at least 6 hours and up to overnight.
In a small skillet over medium-high heat, quickly toast the coconut flakes, stirring constantly so they don't burn. Allow to cool completely and then scatter over the cheesecake.
