Subject: [PATCH 3/8] reset: k210: Use regmap_test_bits in k210_rst_status
Date: Tue, 03 Nov 2026 15:51:23 +0100 [thread overview]
Message-ID: <20261103-reset-regmap-test-bits-v1-3-1b33607a76b0@pengutronix.de> (raw)
In-Reply-To: <20261103-reset-regmap-test-bits-v1-0-1b33607a76b0@pengutronix.de>
Simplify k210_rst_status() by using regmap_test_bits().
Now returns 1 if asserted for all bits.
