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() arch/arm/mach-davinci/da850.c | 51 +++++++++++++++++++++++++++++++++------ drivers/cpufreq/davinci-cpufreq.c | 2 +- 2 files changed, 45 insertions(+), 8 deletions(-) -- 2.9.3
