Subject: [PATCH 1/9] drm: meson: mask value when writing bits relaxed
Date: Mon, 24 Jun 2019 16:47:56 +0200 [thread overview]
Message-ID: <86y31r82fo.fsf@baylibre.com> (raw)
In-Reply-To: 86zhm782g5.fsf@baylibre.com
The value used in the macro writel_bits_relaxed has to be masked since
we don't want change the bits outside the mask.
