clk_{un}prepare is mandatory for platforms using common clock framework. Since
this driver is used by SPEAr platform, which supports common clock framework,
add clk_{un}prepare() support for designware i2c.Signed-off-by: Viresh Kumar <[email protected]> --- V1->V2: - Use clk_prepare_enable and clk_disable_unprepare drivers/i2c/busses/i2c-designware-platdrv.c | 10 +++++----- 1 files changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/i2c/busses/i2c-designware-platdrv.c b/drivers/i2c/busses/i2c-designware-platdrv.c index 76bf108..3a7a4e8 100644 --- a/drivers/i2c/busses/i2c-designware-platdrv.c +++ b/drivers/i2c/busses/i2c-designware-platdrv.c @@ -103,7 +103,7 @@ static int __devinit dw_i2c_probe(struct platform_device *pdev) r = -ENODEV; goto err_free_mem; } - clk_enable(dev->clk); + clk_prepare_enable(dev->clk); dev->functionality = I2C_FUNC_I2C | @@ -180,7 +180,7 @@ err_free_irq: err_iounmap: iounmap(dev->base); err_unuse_clocks: - clk_disable(dev->clk); + clk_disable_unprepare(dev->clk); clk_put(dev->clk); dev->clk = NULL; err_free_mem: @@ -202,7 +202,7 @@ static int __devexit dw_i2c_remove(struct platform_device *pdev) i2c_del_adapter(&dev->adapter); put_device(&pdev->dev); - clk_disable(dev->clk); + clk_disable_unprepare(dev->clk); clk_put(dev->clk); dev->clk = NULL; @@ -229,7 +229,7 @@ static int dw_i2c_suspend(struct device *dev) struct platform_device *pdev = to_platform_device(dev); struct dw_i2c_dev *i_dev = platform_get_drvdata(pdev); - clk_disable(i_dev->clk); + clk_disable_unprepare(i_dev->clk); return 0; } @@ -239,7 +239,7 @@ static int dw_i2c_resume(struct device *dev) struct platform_device *pdev = to_platform_device(dev); struct dw_i2c_dev *i_dev = platform_get_drvdata(pdev); - clk_enable(i_dev->clk); + clk_prepare_enable(i_dev->clk); i2c_dw_init(i_dev); return 0; -- 1.7.9 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
