From 60a6c8257f4144f49a7e0178603dd61ef4424a67 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 17 Feb 2023 14:45:42 -0600 Subject: spi: mpc5xxx-psc: Use platform resources instead of parsing DT properties The mpc52xx-psc and mpc512x-psc drivers use DT property parsing functions for 'reg' and 'interrupts', but those are available as platform device resources. Convert probe functions to use them and simplify probe to a single function. For 'cell-index', also use the preferred typed property function.
