From bf7ddb18f1bfa0b61b4dc43732c114f20900bd4b Mon Sep 17 00:00:00 2001 From: Shiji Yang Date: Sun, 21 Mar 2021 22:43:59 +0800 Subject: [PATCH] ramips: speed up spi frequency for Youku YK-L1 Youku YK-L1 has a huge storage space up to 32 MB. It is better to use a higher spi clock to read or write serial nor flash chips. Youku YK-L1 has Winbond w25q256fvfg on board that can support 104 MHz spi clock so 48 MHz is safe enough. The real frequency can only be sysclk(580MHz ) /3 /(2^n) so 80 MHz defined in dts file will set only 48 MHz in spi bus.
