[PATCH v2] i2c: i2c-tegra: Move clk_prepare/clk_set_rate to probe

From: Mikko Perttunen mperttu...@nvidia.com Currently the i2c-tegra bus driver prepares, enables and set_rates its clocks separately for each transfer. This causes locking problems when doing I2C transfers from clock notifiers; see http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July

[PATCH] i2c: i2c-tegra: Move clk_prepare/clk_set_rate to probe

/unprepare and clk_set_rate calls to the probe function, leaving only clk_enable/disable to be done on each transfer. This solves the locking issue. Signed-off-by: Mikko Perttunen mperttu...@nvidia.com --- drivers/i2c/busses/i2c-tegra.c | 57 +- 1 file changed
