[PATCH 0/2] spi: sunxi: Improve the loading speed

[Michael Walle]

Right now, the maximal transfer speed from an SPI flash on a V3s is
about 240kb/s. That is pretty slow. It turns out, that due to an
error u-boot is setting the maximum frequency to 1MHz. By fixing
that another bug is unearthed: one cannot set a clock divider of 1:1
due to the handling between CDR1 and CDR2 handling. By fixing that
I achieved loading speeds of about 1.5MB/s.

  spi: sunxi: drop max_hz handling
  spi: sunxi: fix clock divider calculation for max frequency setting
