Subject: [PATCH v2 0/5] drm/tidss: Fixes data edge sampling on AM62X and AM62A
Date: Thu, 6 Nov 2025 19:16:47 +0530 [thread overview]
Message-ID: <20251106134652.883148-1-s-jain1@ti.com> (raw)
Currently the driver only configure the data edge sampling partially.
AM62X, AM62A and AM62P require it to be configured in two distinct
registers: one in tidss and one in the Control MMR registers.
Introduce a new dt property to link the proper syscon node from the main
device registers into the tidss driver.
The series targets to fix the issue for AM62X and AM62A, later will add
the changes required for AM62P after DSS support gets upstreamed.
Fixes: ad2ac9dc9426 ("drm/tidss: Add support for AM625 DSS")
Fixes: 5cc5ea7b6d7b ("drm/tidss: Add support for AM62A7 DSS")
