Subject: [PATCH RESEND v7 04/10] drm/bridge: it6505: Change definition MAX_HDCP_DOWN_STREAM_COUNT
Date: Mon, 30 Dec 2024 18:51:22 +0800 [thread overview]
Message-ID: <20241230-v7-upstream-v7-4-e0fdd4844703@ite.corp-partner.google.com> (raw)
In-Reply-To: <20241230-v7-upstream-v7-0-e0fdd4844703@ite.corp-partner.google.com>
From: Hermes Wu <Hermes.wu@ite.com.tw>
A HDCP source device shall support max downstream to 127 devices.
Change definition MAX_HDCP_DOWN_STREAM_COUNT to 127
KSVs shall save for DRM blocked devices check.
This results in struct it6505 growth by ~0.5 KiB.
