From mboxrd@z Thu Jan 1 00:00:00 1970 From: paweljarosz3691@gmail.com (=?utf-8?B?UGF3ZcWC?= Jarosz) Date: Thu, 6 Oct 2016 21:42:21 +0200 Subject: [PATCH] ARM: dts: rockchip: initialize rk3066 PLL clock rate Message-ID: <20161006194221.GA4895@vaio-ubuntu> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Initialize PLL rate while kernel init. No other module does than. Clock rates are taken from rk3066 TRM. Assigned values are for 125 degrees celcius operating point. This gives us performance boost observable for example in mmc transfers.
