[PATCH v4 0/4] ARM: da850: fix pll0 rate setting

[bgolaszewski@baylibre.com (Bartosz Golaszewski)]

While trying to set the pll0 rate from the kernel I noticed there are
two issues with da850 clocks. The first patch fixes an infinite loop
in propagate_rate(). The third fixes an oops in da850_set_pll0rate().
The second patch is just a coding style fix, while we're at it.

v1 -> v2:
- change the approach in 1/3: create a new clock for nand inheriting
  the rate from the aemif clock (verified that nand still works on
  da850-lcdk)
- patch 3/3: also update the davinci_cpufreq driver - the only
  (indirect) user of da850_set_pll0rate()
- s/requested_rate/rate in 3/3

v2 -> v3:
- 1/3: keep the "aemif" connector id for the nand clock
- 3/3: instead of multiplying freq->frequency, divide rate by 1000
- retested both davinci_nand and clk_set_rate() for pll0

v3 -> v4:
- 1/4: add a comment explaining why we're leaving a NULL dev_id
- 2/4: emac_clk is added twice to the clock lookup table too - fix it
  and verify that davinci_mmdio gets a functional clock
- 4/4: s/opp == NULL/!opp/

Bartosz Golaszewski (4):
  ARM: da850: fix infinite loop in clk_set_rate()
  ARM: da850: don't add the emac clock to the clock lookup table twice
  ARM: da850: coding style fix
  ARM: da850: fix da850_set_pll0rate()
