Subject: [PATCH 5.4.y 1/3] mfd: intel_soc_pmic_chtdc_ti: Fix invalid regmap-config max_register value
Date: Mon, 13 Oct 2025 20:17:32 -0400 [thread overview]
Message-ID: <20251014001734.3748199-1-sashal@kernel.org> (raw)
In-Reply-To: <2025101316-disarm-pried-7a1f@gregkh>
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 70e997e0107e5ed85c1a3ef2adfccbe351c29d71 ]
The max_register = 128 setting in the regmap config is not valid.
The Intel Dollar Cove TI PMIC has an eeprom unlock register at address 0x88
and a number of EEPROM registers at 0xF?. Increase max_register to 0xff so
that these registers can be accessed.
