From e17b9f20da7d2bc1f48878ab2230523b2512d965 Mon Sep 17 00:00:00 2001 From: Angelo Dureghello adureghello@baylibre.com Date: Sat, 25 Jan 2025 17:24:32 +0100 Subject: iio: dac: ad3552r: clear reset status flag

From: Angelo Dureghello adureghello@baylibre.com

commit e17b9f20da7d2bc1f48878ab2230523b2512d965 upstream.

Clear reset status flag, to keep error status register clean after reset (ad3552r manual, rev B table 38).

Reset error flag was left to 1, so debugging registers, the "Error Status Register" was dirty (0x01). It is important to clear this bit, so if there is any reset event over normal working mode, it is possible to detect it.
