Subject: [PATCH 15/19] clk: at91: clk-programmable: add mux_table option
Date: Wed, 15 Jul 2020 14:24:23 +0300 [thread overview]
Message-ID: <1594812267-6697-16-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1594812267-6697-1-git-send-email-claudiu.beznea@microchip.com>
Add mux table option. This is necessary for IP versions where
software parent indexes are different than hardware parent
indexes (e.g. SAMA7G5).
