From 8141b6da1763b9db009e5dcf873869bb31bcef45 Mon Sep 17 00:00:00 2001 From: Thomas Richard Date: Mon, 3 Jun 2024 19:01:00 +0200 Subject: regulator: tps6594-regulator: Fix the number of irqs for TPS65224 and TPS6594 The number of irqs is computed to allocate the right amount of memory for the irq data. An array of struct tps6594_regulator_irq_data is allocated one time for all the irqs. Each irq uses one cell of the array. If the computed number of irqs is not correct, not allocated memory could be used. Fix the values used in the calculation for TPS6594 and TPS65224.

Replace the "supply" member of each LDO description with the respective group supply name, so that the supply dependencies can be correctly described in the devicetree. Also fix two off-by-ones in the regulator macros, after some double checking the numbers against the datasheet. This uncovered a bug in the datasheet: add a comment to document this.
