Subject: [PATCH v2 2/3] i2c: at91: fix clk_offset for sam9x60
Date: Mon, 2 Dec 2019 09:01:17 +0000	[thread overview]
Message-ID: <1575277244-6507-1-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1575276957-5615-2-git-send-email-eugen.hristev@microchip.com>

From: Eugen Hristev <eugen.hristev@microchip.com>

In SAM9X60 datasheet, FLEX_TWI_CWGR register rescription mentions clock
offset of 3 cycles (compared to 4 in eg. SAMA5D3).
This is the same offset as in SAMA5D2.

Fixes: b00277923743 ("i2c: at91: add new platform support for sam9x60")
Suggested-by: Codrin Ciubotariu <codrin.ciubotariu@microchip.com>
