Subject: [PATCH 6.12.y 1/3] mfd: intel_soc_pmic_chtdc_ti: Fix invalid regmap-config max_register value
Date: Mon, 13 Oct 2025 18:36:54 -0400	[thread overview]
Message-ID: <20251013223656.3673902-1-sashal@kernel.org> (raw)
In-Reply-To: <2025101305-cheek-copartner-c523@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.
