Subject: [PATCH 3/4] mci: sdhci: add register define for P_VENDOR_SPECIFIC_AREA
Date: Thu, 29 Feb 2024 16:56:59 +0100	[thread overview]
Message-ID: <20240229155700.17443-3-ysionneau@kalrayinc.com> (raw)
In-Reply-To: <20240229155700.17443-1-ysionneau@kalrayinc.com>

This register is standardized by SDHCI (See SD Host Controller
Simplified Specification v4.20 "1.2 Register Map" and
"2.3.14 Pointer Registers to mFFh-100h Area").
 
It is necessary to access some vendor specific registers for
some controllers.
