Subject: [PATCH v6 04/11] clk: at91: clk-master: add 5th divisor for mck master
Date: Thu, 19 Nov 2020 17:43:10 +0200 [thread overview]
Message-ID: <1605800597-16720-5-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1605800597-16720-1-git-send-email-claudiu.beznea@microchip.com>
From: Eugen Hristev <eugen.hristev@microchip.com>
clk-master can have 5 divisors with a field width of 3 bits
on some products.
Change the mask and number of divisors accordingly.
