+Subject: [PATCH] rpi-cirrus-wm5102-overlay: fix pinctrl configuration
+
+Separate GPIOs connected to wm5102 and wm8804 into 2 pinctrl
+blocks and properly reference them from the DT nodes to have
+correct pinmux owners.
+
+Setup spi0 to use only one CS line on GPIO7 so that GPIO8 is
+no longer claimed by spi0 but can be used by wm8804.
