From fcc152f3bf55cec61167b173774cbf717b0ff5e4 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Thu, 3 Sep 2009 22:59:00 +0900 Subject: MIPS: TXx9: Fix spi-baseclk value TXx9 SPI bit rate is calculated by: fBR = fSPI / 2 / (n + 1) (fSPI is SPI master clock freq, i.e. imbusclk freq.) So use imbus_clk / 2 as a spi-baseclk.
