Subject: [RFC PATCH v3 5/5] phy: rockchip-pcie: Adjust read mask and write
Date: Fri, 13 Jun 2025 02:22:22 -0300 [thread overview]
Message-ID: <e8bc1e12ad3c7c38bfef25e696ffbec2b25f312c.1749791474.git.geraldogabriel@gmail.com> (raw)
In-Reply-To: <cover.1749791474.git.geraldogabriel@gmail.com>
Section 17.6.10 of the RK3399 TRM "PCIe PIPE PHY registers Description"
defines asynchronous strobe TEST_WRITE which should be enabled then
disabled and seems to have been copy-pasted as of current. Adjust it.
While at it, adjust read mask which should be the same as write mask.
